Unique Advantages

Conventional circuit breakers use complicated

mechanisms to transfer actions from a single actuator

into the movements of three arc quenching contacts.

Beyond this, the movable contacts are fixed in their

OPEN and CLOSED positions through the use of

mechanical latches. These mechanical arrangements

are subject to severe stresses at C-O operations and are

the main reason for circuit breaker failures.

Tavrida Electric has simplified this mechanical

structure to the greatest possible degree. The ISM

vacuum circuit breaker uses three single-coil magnetic

actuators, one per pole. All the switching elements are

assembled along a single axis. All mechanical

movements are therefore direct and linear. The three

actuators are mounted in a steel frame and

mechanically linked by a synchronizing shaft.

Failure of critical components, such as

• mechanical latching

• gears, chains, bearings and levers

• tripping and closing coils

• motors to charge springs

are completely avoided.

Highly Reliable Drive Mechanism

Top Availability & Reliability

Usually a VCB offers interfaces for mechanical

interlocking which move with every switching

operation. As a result

• the mechanical parts need to be designed to

withstand the extreme acceleration during switching

operations.

• the reliability of the attached mechanical

interlocking can influence the performance of the

vacuum circuit breaker.

For Tavrida Electric´s new generation of ISM the

operation is not coupled with the operation of the

vacuum circuit breaker. By rotating the interlocking

shaft by 90° the moving armature of the actuator is

mechanically locked in its open position. In addition

the actuator coils are disconnected by a microswitch.

The advantages are:

• the number of switching operations of the entire

system is not limited by the mechanical lifetime of the

connected interlocking mechanism.

• the reliability of the switchgear is dramatically

increased.

New Interlocking Philosophy of HD ISM

Interlocking shaft in unlatched position. ISM is closed.

Interlocking shaft in locked position. ISM is open.

Maximizing the benefits of the driving mechanism

requires vacuum interrupters that combine small

dimensions with an extraordinary long mechanical and

electrical lifespan.

The use of a predefined axial magnetic field provides

even distribution of current density and consequently

substantial improvement of vacuum interrupting

performance.

Selected contact material and special contact design

together with optimized movement and switching

speed result in bounce-free closing.

Substantial increase in mechanical lifespan as well as

size reduction of Tavrida Electric vacuum

interrupters was achieved by utilizing metal bellows

consisting of single discs as opposed to the

conventional use of folded steel.

This has resulted in 50 000 (150 000 at response) C-O

cycles at rated current or 100 operations at full short

circuit breaking current without the need to replace or

adjust any parts of the ISM.

Tavrida Electric´s vacuum circuit breaker are

maintenance free over the total life expectancy of at

least 30 years.

Family of TEL-type vacuum interrupters.

Conventional circuit breakers are designed for only

limited monitoring capability. Regular inspections and

maintenance are required to ensure availability during

operation.

Tavrida Electric‘s vacuum circuit breakers are not only

designed to minimize the number of components. In

addition their status is monitored on a continuous

basis. In the unlikely event of failure, an indication

signal is generated by the control module.

A failure can be rectified before an unsuccessful

switching attempt is made.

This clearly results in greater availability of the

electric power supply system. At the same time

scheduled maintenance and costs are drastically

reduced.

Tavrida Electric´s ISM is the most compact and lightest

weight vacuum circuit breaker available. This makes it

possible to design the most compact switchgear

solutions on the market.

The flexible mounting position and the flexible

connection between the Control Module and the

Switching Module make this vacuum circuit breaker

suitable for almost any application.

When purchasing equipment various cost criteria have

to be evaluated, the so called Life Cycle Cost (LCC).

LCC studies measure the impact of a system or project

on long term budgets and its operating impact. The

studies examine factors such as product purchase cost,

maintenance cost, non-availability cost and design

parameters.

The moment you buy, you decide what total cost you

will be facing throughout the life cycle!

• Thanks to its large number of switching operations,

the ISM remains in service longer than any other

vacuum circuit breaker.

• Compact switchgear solutions not only help save

material costs but also provide additional cost savings

because of reduced space requirements.

• Highest availability reduces down-time to an abso-

lute minimum.

• It is maintenance-free, thus reducing overall costs

drastically.

An arc fault instantaneously releases large amounts of

energy. Arcing time is a critical factor in limiting the

damage and risk of personal injury resulting from an

arc flash. The total arching time is determined by both

relay response time and circuit breaker opening times.

The energy released in an arc fault is directly

proportional to the total clearing time. Whilst relay

response times have improved, medium voltage

circuit breaker opening times are usually as long as

five cycles!

Tavrida circuit breakers are designed with the entire

concept in mind – optimizing vacuum interrupter,

insulation, magnetic actuator and control modules.

This has resulted in the fastest circuit breaker, the one

cycle interrupter - a breakthrough for fast switching

and arc flash protection technology.

Once the circuit breaker receives the trip signal from

an arc-flash relay, it is able to interrupt in twelve

milliseconds (HD ISM with CM-15-01S) to provide

increased arc flash hazard mitigation – the fastest arc

fault interruption in the industry – helping to reduce

work-related injuries, fatalities and lost productivity.

Tavrida circuit breakers are fully compatible with

standard arc-flash relays such as the SEL 751A.

One Cycle Interruption -Reducing Arc Flash Hazards

The step sequence of arc interruption protection with

Tavrida circuit breaker:

• Arc flashlight occurs

• SEL 751A reacts within 5ms and applies Trip

command to control module of circuit breaker

• CM-15-01S control module reacts within 4ms and

makes circuit breaker tripping

• Tavrida HD ISM circuit breaker opens within

maximum 8ms (15ms for LD ISM)

• Arc extinguishes at the following zero crossing or

current

One Cycle Interrupcion

Arc Flash Safety

Voltage decreases or complete supply interruptions

represent the most important and critical problems

for the quality of energy supply today. It is especially

true that voltage disturbances with electronic control

systems and other sensitive installations can lead to

complete loss of production and long stoppage time.

Possible areas of utilization include, for example:

Auxiliary installations serving power stations

• Steam power stations

• Gas turbine power stations

• Combined cycle power stations

• Nuclear power stations

Environmental technology installations

• Flue gas purification

• Refuse incineration installations

Voltage supply to continuous industrial processes

• Chemical plants

• Industrial facilities with high degrees of automation

• Fiber manufacturing

• Petrochemical processes

Fast Automatic Transfer

In order to realize a permanent availability, the load

is supplied from at least two synchronized feeders

which are independent from one another and which are

equipped with High Speed Transfer Devices. In doing

so, the High Speed Transfer Device has the task of

ensuring uninterrupted continuous operation of the

connected devices in case of a power supply

breakdown, taking into account different physical

factors, through the most rapid possible transfer to a

different feeder kept stand-by.

The typical decay characteristics (voltage and

frequency) of a disconnected busbar and the possible

closing moments are shown in the figure.Busbar with two feeders

The execution of fast transfers is the most preferred.

A fast transfer takes place when the both the main and

the stand-by feeder are within specified limit values

at the moment of initiation, e.g. that slip and phase

angle are limited between the networks and the

stand-by voltage lies above a minimum value. Here the

open and close commands to the circuit-breaker from

the High Speed Transfer Device are issued

synchronously. The current-free transfer time occurring

in this case for the users is exclusively dependent upon

the difference between the operating time for closing

and opening the circuit breakers concerned.

Tavrida circuit breakers are designed in a way to

provide both trip and close time minimal in the

industry. Complete changeover can take no more than

50ms with a proper digital relay, for example SUE 3000

or SEL 571, with a current free transfer time (dead

time) 12ms.

An exemplary oscillogram of a fast transfer caused by

main feeder fault with dead time of approximately 20

ms is shown in the figure.

In case of power supply failure the TEL manual

generator CBcomp_MG_1(110_40) can be used as

reserve power supply for CM_1501_1(220_x)

This optional amendment to CM-15 allows having an

opportunity of performing emergence close operation

at any time independently from availability of

standard or emergency power supply system and

allows to increase reliability and applicability of the

TEL vacuum circuit breakers sufficiently.

In the OPEN position the vacuum interrupter contacts

are held open by the force of the opening spring. The

opening spring is located in the monostable magnetic

actuator.

To close the vacuum interrupter contacts, a current

pulse derived from the closing capacitor in the control

module is injected into the actuator coil. The current

in the coil produces a magnetic flux in the gap

between the upper yoke and the actuator armature.

The rising coil current increases the magnetic flux and

the electromagnetic attraction between the yoke and

the armature, eventually overcoming the restraining

force of the opening spring. The armature, drive

insulator and moving contact start to move.

As the armature moves towards the upper yoke, the air

gap decreases, and the magnetic attraction force

consequently increases. This increasing force

accelerates the armature, drive insulator and moving

contact to a closing speed of 1m/s. This optimum

speed ensures the complete absence of contact bounce

and reduces the probability of the vacuum gap

prestriking before the contacts close.

When the contacts close, the moving contact stops,

but the armature travel continues with rapid

decelaration caused by the compression of the contact

pressure spring. In the final position of the armature

the coil current saturates the ring magnet. The

saturation increases the power of the ring magnet to a

level that generates sufficient flux to hold the

armature in CLOSED position after the coil current has

been switched off.

In the CLOSED position, the vacuum interrupter

contacts are kept closed by the force of the magnetic

actuator. Intensive testing has proven that the residual

flux of the ring magnet is sufficient to hold the

actuator CLOSED even under vibration and impact

conditions.

To open the vacuum interrupter a small current of

opposite polarity derived from the opening capacitor

in the control module is passed through the coil for

15-20 ms. This current partially demagnetizes the ring

magnet and reduces the magnetic holding force on the

armature. Opposing forces from the charged opening

spring and the contact pressure spring cause the

armature and the moving contact to release

and accelerate rapidly, ensuring a high interrupting

capacity.

The ISM can also be manually opened. When the

synchronizing shaft is rotated, a force exceeding the

magnetic attraction forces of the ring magnet is

applied to the armature, which subseqently starts to

move. As the air gap increases, the opening spring and

the contact pressure spring overcome the magnetic

holding force, and the vacuum interrupter opens.
