OJONIndoor type Disconnectors

1...24 kV

General

Compact dimensions, direct current

paths, double-knife construction

and cast resin insulators are common

to all OJON -type disconnectors.

The high short circuit strength of

these disconnectors is a result of

these features. Contact pressure

is achieved by spiral springs which

compress the knives.

Silver-plating prevents the contact

area of the contact and knives from

ageing, and keeps the temperature

rise within the limits set by the

standards. Owing to the double-knife

construction, forces needed to

operate the disconnectors remain

moderate even at high rated currents.

The operating levers of the discon-

nectors can be mounted on a flat

base. Busbar joints OJON�ZWJ 5

and 6 may be used for disconnec-

tors rated 2500 A and 4000 A. The

frames and levers of the discon-

nectors are painted green, and the

shaft terminals are treated with

anti-rust varnish. The knives are

painted red, which makes their

position clearly visible and gives a

pleasant look to the whole dis-

connector.

The contacts of the disconnectors

are made of copper bar for 630 A and

of cast copper for 1000...4000 A.

Aluminium busbars can be con-

nected, using jointing grease,

to 630...1600 A, disconnectors,

OJON�ZWJ 5 and 6 terminals and

earthing switches.

Indoor type Disconnectors


Standards and operating conditions

The disconnectors meet the requirements of IEC Publ. 129 (1984) and the Safety Regu-

lations of the Finnish Electrical Inspectorate (Sähköturvallisuusmääräykset). In accordance

with the standards, the ambient site temperature for indoor disconnectors, must be

�25 oC...+35 oC, and the access of unusually high quantities of dust, smoke, caustic

gasses and humidity to the site must be prevented.

Disconnectors OJON 3�1 A 1000, OJON 3�1/1600, OJON 3�1 A 2500 and OJON 3�1

A 4000 have been approved by the Register of Shipping of the U.S.S.R.

Mounting

Normally the disconnectors are mounted in the upright position with the hinges at the

bottom. Other positions are also possible provided that the operating or locking device

ensure that the knives stay in the open or closed position. Wall mounting with the knives

in a horizontal position must, however, be avoided, as the knives may bend down

sideways from the bearings.

Ordering information

1. Type and quantity.

2. Rated voltage Ur.

See tables 1 and 2, pages 4 and 5.

3. Rated current Ir.

4. Rated peak withstand current Ip.

Ip of the disconnector > network impulse short-circuit current Is.

The distance of the nearest post insulator is shown in table 2.

5. Rated short-time withstand current Ik.

Ik of the disconnector > network I1s. Ik is given in table 2 as 1 s value.

Any other length of continuous short-circuit current Ik2 of the network is

reduced to 1 s value with the formula below.

The formula is valid when the duration of tk2 > 1s.

Ik = Ik2 Ö tk2 / s. tk is the duration of Ik2.

AccessoriesEarthing knives, operating arms and manualoperating devicesTechnical data and ordering information

Earthing Knives

As shown in table 3 (page 6) the 630 A OJON_ disconnectors can be supplied

with either an upper or lower earthing knives. Earthing knives have the same

short-circuit strength as the corresponding disconnectors.

The main switch and earthing knives are interlocked with a locking device

so that they cannot be closed simultaneously. The locking device is normally

on the left side of the disconnectors. A locking device prevents the earthing

knife from opening and closing under its own weight.

Disconnector control

The following can be used as an operating mechanism for the disconnectors:

� operating rod NWA�ZS 5 (>1 kV) or NWA-ZS 6 (< 1 kV) and hook end

NWA�ZH 6 and arm YASKA 25

� manual operating mechanism OJO�ZA 1 or UEKO 2C3

� motor-operated control mechanism UEMC 40_. Refer to catalogue

34 UEMC 36_ and 34 UEMC 44_.

Motor Operating device UEMC 40_

The type and construction of motor operating device depends on the location

and accessories required. The device can be fitted to the disconnector

shaft or the front of the cubicle. When mounting on the shaft, check that there

is enough space between the disconnector shaft and mounting surface. When

the motor operating device is fitted on the front of the cubicle, the drive is

transfered using a lever system. Local electrical control (Pushbuttons) of the

operating device is available.

Manual operation is also possible by using an operating rod or control handle

when a motor operating device is fitted.

Operating arm

The simplest control mechanism is an operating arm and an operating rod.

Opening of the disconnector can be prevented with locking coil OJO�ZLA 6.

Manual operating mechanism, alternative A,

OJO-ZA 1

The manual operating mechanism OJO�ZA 1 for mounting on the front wall

of the cubicle, interlocks the disconnector in the extreme positions with the

help of a stall lever. A suspended pin ensures retention in these positions. The

end that comes through the front panel of the cubicle is covered with a

protective cover that can be locked with a padlock. The manual operating

mechanism can be supplied both with locking coil OKO�ZLA 3 and auxiliary

switch OLAN�AL 1. When there is no auxiliary voltage, the interlock (of the

locking coil) can be opened manually. In accordance with the standards, the

closing movement of the disconnector is from down-position to up-position.

Manual operating mechanism, alternative B,

UEKO 2C3

This manual operating mechanism comprises of a beveled gear on the end

of a shaft from the disconnector, a joint fitted with a position indicator on

the front panel and a control tube joining the two parts. Due to the joint,

the control tube can be moved through an angle of ±40 degrees from the

verticle position. The tube is to be cut to a suiatble length when installing.

The indicator locks the disconnector in the extreame positions. The operating

mechanism may also be locking with a locking coil UEKO-ZL 1 and padlock.

By turning the angle of the beveled gears the operating direction of the

disconnector can be adjusted to always be the same.

Auxiliary switches

Auxiliary switch OLAN-AL 1 can be fixed to the cubicle wall, in connection with

manual operating mechanism or to the frame of the disconnector. The

movement is transmitted from the shaft of the disconnector or manual

mechanism to the switch with levers and intermediate bars. Switches are

available with 6 or 9 change-over contacts. The contacts are silver-plated

and are double breaking. Protection class is IP20.

Interlocking


Interlocking

The use of locking devices in connection with different disconnectors is

detailed in table 3, page 6.

A. Disconnector interlocking when subject to gravity or

short-circuit and other disturbances

When operating arm controlled, the disconnectors are interlocked with locking

device OJO�ZE_ or locking coil OKO�ZLA 6. When the disconnector is

mounted in a horizontal plane, locking device OJO�ZE_ must always be used

to prevent the knives from closing under their own weight. Manual operating

mechanism OJO�ZA 1 locks the disconnector in the closed and the open

position with no additional equipment.

B. Disconnector interlocking to prevent unintentional

operation

When operating arm controlled, locking coil OJO�ZLA 6, which is fixed to the

frame of the disconnector is used. Manual operating mechanism OJO�ZA 1

can be locked with a padlock or locking coil OJO�ZLA 3. Manual operating

mechanism type UEKO 2C3 can be locked with a padlock or locking coil

UEKO-ZL 1.

Locking coils

The auxiliary control voltage of locking coils (OJO�ZLA 3 and 6) is either

DC or full-wave rectified alternating current. In the absence of voltage, the

interlock can be opened by pulling the armature with the operating rod or by

hand. Locking coil OJO-ZLA 3 is used with the operating mechanism while

locking coil used OJO�ZLA 6 is fixed to the left or right side of the disconnector.

Locking coil UEKO-ZL1 is to be fitted to the manual operating mechanism

UEKO 2C3 position indicating device on the inside of the cubicle.

Fuse-bases

The frame of the fuse-bases is made of steel plate and the insulators of cast
