2. Product features:

As the high voltage power supply is a core product for electrostatic dedusting, we always pay

close attention to technical progress, seek innovation and improve strategies.

GGAj02 series high voltage power supply takes the HVC-ZC11 intelligent controller for high

voltage power supply most recently researched and developed by our company as its kernel control

component. The HVC-ZC11 intelligent controller for high voltage power supply is a new generation

controller designed and manufactured by using modern electronic technology, which is focused on

four great objectives of “all-digital technical feature, high precision spark response and control,

ingenious control function and network-based design concept”, based on sufficient absorption of the

essence of DAVC controller product manufactured by American GE company and in combination

with many incisive control theories. The product has the following main technical features:

It selects the 32-bit ARM7 core based MCU as its central processing unit (CPU), which

can acquire relevant data in real time and calculate the electric field parameter and spark

parameter rapidly, thus controlling the trigger angle of silicon controlled rectifier accurately.

It has advantages such as rapid response speed, accurate control and high reliability, etc.

It selects 240×128 high-brightness blue-screen LCD for information display. Total Chinese

information display and advanced wizard push-key program make the man-machine

interface become very clear and easy for operation. It can be designed into multiple

language display according to needs so as to meet the requirements of export projects.

The advanced control program is provided with many operating modes, which can be

selected appropriately according to the use requirements in different industries and various

operating conditions on site so as to make the electrostatic precipitator reach the best

operating effect. Its dynamic spark tracing and detection technology can automatically

distinguish flashover in different intensities and carry out corresponding control, thus

3

making the voltage of electric field recovered from flashover as fast as possible and

improving the efficiency of dust collection. Its perfect and reliable protective functions

make the electrostatic precipitator able to operate stably and reliably for a long period of

time.

With the photoelectric full isolation technology and switch power technology as well as the

circuit board designed and manufactured by adopting advanced surface mounting

technology (SMT), the product is featured with preeminent quality, high reliability, strong

anti-interference ability, etc. Meanwhile, the controller is mounted on the door plate with

advantages such as compact structure, convenient operation, etc.

The shutdown recording program can record the most recent fault as well as the operating

parameters and time when the fault occurs, which provides great convenience in the

troubleshooting. Meanwhile, the controller implements registration management and green

shade service, thus the user can obtain the best aftersales service.

With strong communication networking function, it can realize seamless communication

with the DCS system of our party or a third party.

a. It adopts the most common RS485 serial communication interface on site and

follows MODBUS communication protocol, thus it can conduct data exchange directly

with the PLC and DCS of any mainstream brand in the world; the operating data and

controlling parameters of each power supply can be uploaded to the host computer of DCS

through MODBUS communication protocol; alternatively, the high voltage data of several

electric fields can first be integrated to the PLC in the low voltage control system and then

be uploaded to the host computer through the communication interface (Ethernet or

MODBUS) on the PLC itself by utilizing the margin list, and the host computer manages,

regulates and controls each high voltage equipment indirectly through PLC.

b. It reserves CAN2.0 communication interface, which can realize the high speed

communication connection between up to 127 sets of high voltage power supplies and a

single PLC or host monitoring computer at the same time, build the required DCS work

station and realize data acquisition and exchange with the highest communication speed up

to 1MB/S (40M) and the maximum communication distance of a single node up to 10KM

(5KB/S). For the user who requires CAN2.0 communication, it only needs to change the

4

communication module.

c. Besides being designed with RS485 and CAN2.0 full open communication

interfaces, the HVC-ZC11 intelligent controller for high voltage power supply is also

designed with hard wired communication interfaces, which can build non-open

communication connection conveniently with the DCS of a third party and realize the

function of remote startup and shutdown and voltage regulation of equipment.

Main Structure and Operating Principle

I. Product structure and outline dimensions

The complete set of high voltage rectifier for electrostatic precipitator is commonly composed

of high voltage control cabinet, rectifier transformer and damping resistor. If the user selects the

outdoor type (with the cable exit at the high voltage side) rectifier transformer, the high voltage

isolation switch cabinet can be provided according to the user’s requirements.

1. High voltage control cabinet

The high voltage control cabinet is of standard cold bent steel frame structure, with uniform

7

outline dimensions of 600×600×2200. The color of cabinet frame is: GSB05-1426-2001 [light sea

(iron) blue], and the color of door plate is: GSB05-1426-2001 (sea grey). The cable entry mode is

divided into: top entry and bottom entry. If you have any special requirement for the outline

dimensions and colors, please put forward it when placing an order.

For the appearance of high voltage control cabinet, see attached figure (3).

2. Rectifier transformer

The rectifier transformer is an oil-immersed natural cooling type, including such two sections

as of alternating current booster and high voltage silicon bridge rectifier stack. The transformer

adopts the ri-shaped iron core (“ri” is a Chinese character), which is featured with small loss, low

temperature rise and small volume through computer-aided optimized design. The silicon rectifier

stack adopts avalanche components with long service lifetime, which can be recovered by itself

after instant breakdown and is mounted in the transformer container.

According to the series program recommended by the national standards, the rated output

direct current (average) of rectifier transformer is (unit: A): 0.05, 0.1, 0.2, 0.4, 0.6, 0.7, 0.8, 1.0, 1.2,

1.4, 1.6, 1.8 and 2.0, that is, thirteen grades altogether; and the rated output direct current voltage is

(unit: KV): 40, 50, 60, 66, 72, 80, 90, 100 and 120.

For the rated current and voltage beyond the above series program, we can provide them

according to the user’s requirements.

The structural type of rectifier transformer is high impedance rectifier transformer, which is

divided into the type of cable exit at the high voltage side (outdoor type) and the type of cable exit

at the top (indoor type).

For the outline drawing of rectifier transformer, see attached figure (4).

3. Damping resistor

The damping resistor is connected in series between the high voltage output end of rectifier

transformer and the cathode line of electrostatic precipitator, which is a protective component in the

electric circuit system of rectifier. It plays an important role in the suppression of flashover impact

current, absorption of higher harmonic wave and protection of control circuit during the operation.

For the outdoor type rectifier transformer (with cable exit at the high voltage side) provided

with high voltage isolation switch cabinet, the damping resistor is commonly mounted in the high

voltage isolation switch cabinet.

8

The resistance and power of damping resistor shall be selected according to “Parameter List

for Main Components in the Primary Circuit” (attached table 2).

4. High voltage isolation switch and switch cabinet

The high voltage isolation switch is used to connect the high voltage incoming terminal in the

electric field of electrostatic precipitator with the high voltage output terminal of rectifier

transformer or the ground so as to ensure the personal safety during the repair of electrostatic

precipitator.

The high voltage isolation switch cabinet is generally used with the outdoor type rectifier

transformer and is placed between the rectifier transformer and temperature holding cabinet. The

flange of high voltage protective cover on the outdoor type rectifier transformer shall be joined to

the inlet flange of switch cabinet. The high voltage inlet and outlet directions of high voltage

isolation switch cabinet as well as the on-off operating direction of high voltage isolation switch

shall be determined by the user according to site arrangement.

II. Operating principle of primary circuit

For the electric schematic diagram, see attached figure (2).

The electric schematic diagram is mainly composed of primary circuit, operating control

circuit and auxiliary circuit (e.g. cooling fan), etc. The single phase alternating current 380V, 50 Hz

power supply is connected with the primary contactor KM1 through fuses FU1 and FU2. After the

control of primary contactor KM1, one output is connected with the input terminal A of transformer

through two silicon controlled rectifiers V1 and V2 in inverse parallel; the other output is connected

with the X1 terminal of transformer through the primary current transformer TA1. The phase-shifted

and voltage-regulated single phase alternating current power supply is output as the negative high

voltage after the voltage boosting and current rectification of transformer, and is supplied to the

electrostatic precipitator through the damping resistor. R7 and R6 are respectively the current

sampling resistor and voltage sampling resistor at the direct current high voltage side. The

secondary current and secondary voltage sampling signals are sent to the controller, which output

the conduction angle of trigger signal controlled thyristor (silicon controlled rectifier) after the

operation and processing of computer system. This automatic control system adopts the dual

closed-loop automatic control system with current inner loop feedback and voltage outer loop

feedback. The functions of other main components in the primary circuit are as follows:

Equipment Installation and Use

I. Equipment inspection and installation

1. Installation and inspection of transformer

(1) After the transformer is transported to the installation site, make sure to inspect if the

porcelain bush has any collision injury and if the sealing section has any oil permeation

phenomenon.

(2) The body of transformer is provided with four symmetrical lifting hooks, which are used to

lift or hoist the entire transformer. The lifting eyes on the tank cover are only be used for core lifting

(note: these lifting eyes cannot be used for lifting the entire transformer). During the lifting, the

angle between the transformer body and vertical line shall not exceed 30%. If this condition cannot

be satisfied, a special intermediate crossbeam can be used to lift the transformer.

(3) Insulation inspection

The insulation resistance of rectifier transformer can be checked and measured with a

1000V/2500V megger. Before the inspection, the secondary voltage/current sampling board shall be

dismantled. The readings of insulation resistance are as follows:

hook up the lifting eyes on the transformer tank body for lifting; if the lifting hooks are used for

lifting, then the diameter of lifting hooks shall not be more than 30mm so as to avoid damaging the

radiating fins due to compression. It is strictly forbidden the use the lifting eyes on the tank cover to

lift the entire transformer.

(2) When the high voltage rectifier transformer is installed in the isolation chamber, it shall be

kept more than 1m away from walls.

(3) After the installation and commissioning of high voltage rectifier transformer are finished

in position, the universal wheel shall be fixed at the bottom of transformer with channel steel so as

to prevent the displacement.

3. Installation of high voltage control cabinet

The high voltage control cabinet must be fixed with anchor bolts according to the requirement

of outline drawing.

4. Installation and arrangement of circuit

(1) Conduct wiring according to attached figure 1. Besides providing 380V alternating current

power supply, the power supply incoming line must also provide N line with a cross section not less

than 2.5mm2.

(2) According to relevant provisions of low voltage power distribution, select the specified

copper core cable to connect the power supply, high voltage control cabinet and silicon rectifier

transformer. The current and voltage feedback signal wires shall adopt RVVP4×1.5mm² shielded

cable, and the metal shielded layer shall have single end earthing within the controller or high

voltage control cabinet. When the equipment communicates with the PLC or host computer, it shall

adopt DJYPVP3×2×0.5 mm² triple twisted pair pairwise shielded cable.

Note: the secondary current and voltage sampling signals and the rectifier transformer oil

temperature sampling signal must be connected with the control cabinet through their respective

shielded cables, which cannot be replaced by common control cables.

(3) The earthing terminals of control cabinet, rectifier transformer and load shell must all be

grounded very reliably, with their earthing resistance not more than 2.0�. In order to prevent the

interference, the earthing terminals of high voltage control cabinet, rectifier transformer and load

(e.g. the anode of electrostatic precipitator) shall be connected with each other at the same point for

earth connection

12

The detailed arrangement method for earthing wires is as follows: a piece of multi-strand

copper core wire with a cross section not less than 35mm2 shall be directly arranged from the

earthing terminal of each rectifier transformer to the earthing busbar of high voltage control cabinet.

Meanwhile, a piece of multi-strand copper core wire with a cross section not less than 16mm2 shall

be arranged from the earthing terminal of rectifier transformer to the earthing bolt on the

transformer shell, then a piece of multi-strand copper core wire with a cross section not less than

16mm2 shall be arranged from the earthing bolt to the anode of load (i.e. the shell of main body).

(4) The equipment wiring shall comply with relevant provisions of high voltage and low

voltage wiring specified by the country.

(5) In order to prevent the interference, during the cable arrangement, the power cable, signal

cable and communication cable shall be separately arranged so as to avoid mutual cross

interference.

II. Simulation commissioning of equipment

1. False-load test of the high voltage control cabinet

In order to ensure the safe reliability of equipment, before the first operation and reoperation

after the repair of the equipment, two pieces of power primary cables must be disconnected between

the high voltage control cabinet and rectifier transformer; two incandescent lamp bulbs with their

power not less than 100W shall be connected with each other in series and then be connected with

the power outlet terminal of high voltage control cabinet. Do voltage stepup test in manual

operating mode by using normal equipment starting method so as to ensure that the equipment will

be connected with the rectifier transformer to work at load only after the silicon controlled rectifier

can be triggered normally.

2. Fault alarm test of the equipment

(1) Oil temperature alarm: the rectifier transformer shall be equipped with a PT100

temperature sensor. When the transformer oil temperature reaches 85 , the controller will send out

a trip signal and give an alarm, and the display screen of controller will display the oil temperature

out-of-tolerance fault of transformer.

(2) High voltage safety interlock: after the installation of transformer, control cabinet and load,

it is necessary to interlock the high voltage output available switch with the startup operation of

control cabinet so as to ensure safe power supply. When the safety interlock is not available, it is not

13

allowed to start the equipment, and the controller has the prompt for unavailable safety interlock.

(3) Load open-circuit/short-circuit protection: when the high voltage output of transformer is

open-circuited, the controller can trip for open circuit and meanwhile control the secondary voltage

does not exceed the rated value; when the high voltage output of transformer is short-circuited, the

controller can trip for short circuit and meanwhile control the secondary current does not exceed the

rated value.

III. Equipment use

1. Check and adjustment before the first startup

(1) Disconnect the power supply for entering the control cabinet;

(2) Check if the plug of controller is connected reliably;

(3) Check if all wires are correct and reliable;

(4) Check if all fuses are in good conditions and without looseness;

(5) Check the insulation of load (electric field of electrostatic precipitator) with a 2500V

megger, and its resistance value shall be above 100M� generally.

(6) Check if the secondary current and voltage sampling resistances comply with the

requirements with a multimeter. For the standard secondary current sampling resistance of the

equipment of various specifications, see attached table (2), and the secondary voltage sampling

resistance is 7.8K�.

2. Local startup of the equipment:

Close the circuit breaker QF1 of operating power supply, and the “power indicator” green lamp

HL1 will be lit. The master switch SA1 will be changed over to “local” position. The HVC-ZC11

high voltage intelligent controller for power supply will be energized for self-check and be rest by

itself. The display screen will display the salutatory interface, then enter the shutdown recording

interface. After the “confirmation” key is pressed, the system will enter the initial waiting interface.

At this time, if the “automatic” key is pressed, then the controller will automatically control the

pick-up of primary contactor KM1. After that, the voltage will be increased slowly until it reaches a

set limit value. Then, it will operate around this value. When the “manual” key is pressed, it will

enter the manual waiting interface. At this time, the required operation can be selected according to

the menu. After the primary contactor KM1 is picked up, the “power indicator” green lamp HL1

will be turned out and the “system operating” red lamp HL2 will be lit, thus the system will enter

14

the operating state.

Note: when starting the equipment for operation, if the controller has the prompt for

“unavailable safety interlock”, then it indicates that the high voltage isolation switch is not changed

over to the “operating” position or the interlock is connected virtually. At this time, the equipment is

unable to start up. Please try it again after confirming the position of high voltage isolation switch.

3. Local shutdown of the equipment:

After the “stop” key is pressed, the controller will first make the output voltage drop to zero,

then release the primary contactor KM1 and disconnect the primary circuit. At this time, the

“system operating” lamp HL2 is turned out and the “power indicator” lamp HL1 is lit, then it will

be alright after making the master switch SA1 change over to the “off” position. 4. Remote control

of the equipment:

When the equipment requires remote centralized control, first close the circuit breaker QF1 of

operating power supply, then make the master switch change over to the “central control” position.

At this time, the controller is unable to carry out operations such as startup, voltage step-up or

controlled by the remote PLC or DCS.

5. Operating instructions of the controller

The HVC-ZC11 intelligent controller is provided with a 240x128 high-brightness liquid crystal

display (LCD) and four thin-film keys as the man-machine dialogue window. Among four keys,

except that the reset key is a fixed key, other three keys are draw keys, with their current functions

to be determined by the wizard push-key program. The operator only needs to carry out operation

according to the prompt on the LCD, which is very straight and simple. Six commonly used display

interfaces are shown as follows:

6. Fault trip:

16

When the faults such as permanent short circuit, open circuit, primary overload, oil

temperature out-of-tolerance, heavy gas alarm, etc. occur in the electric field, the HVC-ZC11

controller will judge them automatically and output the trip signal. At this time, the startup and

shutdown control relay KA2 will be de-energized, the contacts KM2 and KM1 will be released to

disconnect the primary circuit, the fault alarm relay KA3 will be energized, and the fault alarm

buzzer HA1 will give a sound and light alarm. LCD will display the fault parameters and fault

causes. After the “confirmation” key is pressed, the fault alarm relay KA3 will be energized, stop

giving an alarm and return to the initial waiting interface.

IV. Precautions for equipment use

1. In order to ensure the equipment and personal safety, it is strictly forbidden to change over

the high voltage isolation switch or switch off the power supply switch directly when the equipment

is at operating state.

2. The current and voltage feedback signal wires between the rectifier transformer and control

cabinet must use metal shielded wires so as to prevent from the interference.

3. In order to ensure the personal safety, it is strictly forbidden to enter the high voltage

isolation chamber during the operation of equipment.

Equipment Maintenance and Service

I. Service of high voltage control cabinet

Regularly check if there is any overheating, looseness or damage on the components and parts,

circuits and wires within the high voltage control cabinet; according to the ambient conditions on

the site, regularly clean and wipe the high voltage control cabinet to keep the cleanness in the high

voltage control cabinet and rectifier transformer bushing.

II. Service of rectifier transformer

1. Regularly check if the drying agent of rectifier transformer has any change in color. If any, it

shall be replaced promptly.

2. Regularly check if the oil level and temperature rise of rectifier transformer are normal. If

not, please handle them promptly.

3. Regularly wipe the shell of rectifier transformer and check if the shell has any rusting so as

to ensure the cleanness of rectifier transformer and soundness of protective paint on the shell.

4. The transformer oil test shall be conducted annually, which shall comply with the provisions

of GB/T7595-2000. The breakdown voltage shall not be less than 40KV/2.5mm, otherwise,

the oil shall be filtered again or replaced with new oil. The withstand voltage value of new oil

shall be more than 45KV/2.5mm.

III. Measurement of earth resistance

The earth resistance of system shall be measured annually, and the earth resistance value of

each point shall not be more than 2.0�.

IV. Active part inspection for rectifier transformer

21

1. When it has any doubt about the interior after the rectifier transformer has any collision or

other events during the transportation or it needs to conduct repair after a fault occurs during the

operation, the active part inspection shall be conducted.

2. Active part operation for rectifier transformer

(1) Before the active part is lifted, first loosen the oil drain valve on the lower part of

transformer tank and discharge about 80KGS of transformer oil. Pay attention to ensure that the

discharged oil is contained and sealed in a clean vessel so as to prevent the transformer oil from

being polluted. Meanwhile, its storage time shall be as short as possible for fear of becoming damp

and reducing the dielectric strength.

(2) Remove all connecting bolts on the tank cover and tank body.

(3) Before the active part is lifted, for the outdoor type, first open the small cover plate and

stretch the hand into the oil tank. The lifting can be conducted only when the wires between the

high voltage output and porcelain insulator connecting terminal are released with a wrench. After

the active part inspection is finished, the active part shall be put into the oil tank and then restored to

its original condition.

(4) When the active part is lifted, pay attention to the balance of gravity center on the active

part. Four corners of the oil tank shall be monitored so as to prevent from the collision between the

active part and tank body and cause any damage.

(5) After the active part inspection is finished, put the active part into the oil tank and install

and fasten it in opposite direction. Connect the high voltage output wire and fill in the transformer

oil.

3. Main items in the active part inspection are as follows:

(1) If the coil has any collision injury and if the silicon rectifier stack has any crack;

(2) If the high voltage porcelain insulator has any damage and if all parts and fasteners have

any looseness phenomenon;

(3) The iron core shall be grounded reliably and only grounded at one point; for that with a

core-crossing screw stem, measure the insulation resistance between it and core with a 2500V

megger, and the resistance value must be more than 1000M�.

4. Precautions for the active part inspection for transformer:

(1) The lifting of active part shall be conducted in good weather conditions when it is dry

22

without dust and moisture (the relative humidity shall not be more than 75%) and at a clean position.

Its lifting time shall be as short as possible so as to avoid from becoming damp or being polluted

and thus reducing the dielectricity. The active part inspection cannot be conducted in rainy days.

(2) When the lifted active part is exposed to the air, its continuous time for contacting with the

air outside shall not exceed the following provisions:

In dry air (the relative humidity of air shall not be more than 65%) � 3 hours.

In humid air (the relative humidity of air shall not be more than 75%) � 1 hours.

(3) After the rectifier transformer goes through the active part inspection, the power-on test can

be conducted only after the transformer oil is filled back and generally stands for 24 hours for fear

of high voltage discharge in bubbles.

5. Withstand voltage test for transformer oil

If the condition permits, the breakdown voltage shall be measured for transformer oil. The oil

sample shall be taken from the oil drain valve. At this time, the oil temperature shall not be lower

than +5 . The transformer oil must go through the withstand voltage test, and the average instant

breakdown voltage value of five tests shall be more than 35KV/2.5mm. If the breakdown voltage of oil

is lower than the required value, it can be used only when the causes are found out and it is handled

accordingly. In addition, if it needs to replenish oil, it is preferable to add the oil of same grade as far as

possible. In case the oil grade is different, then it can be mixed for use only after the chemical analysis is

conducted in advance.

6. Withstand voltage test for transformer

The rectifier transformer has already go through the induced voltage withstand test and applied

high voltage test before leaving the factory. If the high voltage test is required on the site, then it is

necessary to short circuit the high voltage set on the silicon rectifier stack, disassemble the high

voltage measuring resistor and current feedback outlet wire, put them into the oil again and stand

for 24 hours. Then the high voltage porcelain insulator shall go through the withstand voltage test to

earth. Otherwise, the applied high voltage test can not be conducted. For the silicon rectifier

transformer below 72KV, its test voltage shall be more than 1.1 times of rated voltage and less than

1.5 times of rated voltage.
