Interlock system

For personnel safety, SecoVac 3.3kV-27kV

is designed with a number of mechanical

and electrical interlocks. For example,

breaker contacts must be open before

the breaker can be moved from test to

service position. A positive mechanical

stop is provided when the breaker

reaches the service or test/disconnect

positions. Mechanical rejection interlocks

are provided to permit only the insertion

These and other necessary interlocks

provide a comprehensive safety system.

Furthermore, springs automatically

Overview

The Multilin 3 Series of protection relays

are highly functional, economical

protection relays for feeders, motors and

transformers. By providing an economical

system for protection, control, monitoring

and metering, and both local and

remote user interfaces in one assembly,

�� <`��!��

eliminate the need for expensive discrete

components.

The Multilin 3 Series provides detailed

diagnostic information allowing users to

troubleshoot and minimize downtime.

Detailed diagnostics is provided via the

?�\��

and the 192 cycle Oscillography report

sampled at 32 samples per cycle.

The robust Multilin 3 Series streamlines

Preventative maintenance

The Multilin 3 Series allows users to track

relay exposure to extreme environmental

conditions by monitoring and alarming

at high temperatures. This data allows

user to proactively schedule regular

maintenance work and upgrade activities.

All relays utilize EnerVistaTM setup

software for communication, monitoring

and metering. Actual values, setpoints,

status, trending, and waveform capture

information may all be viewed via

the software, and can be used for

troubleshooting.

Working Principle

Working Principle of Operating Mechanism

The vacuum gas pressure inside vacuum interrupter is less than

1.33×10-3Pa. Under normal circuit conditions the interrupter is

closed. Arcing is established within the interrupter by withdrawing

the moving contact from stationary contact. This arc burns in

the metal vapor evaporated from local hot spots on the contact

surfaces. The metal vapor continually leaves the inter-contact

region and recondenses on the contact surfaces and surrounding

metal vapor condensation shield. The latter is usually isolated

from both contacts and serves to protect the glass or ceramic

envelope from vapor deposition. At current zero, vapor production

ceases and the original vacuum condition is rapidly approached.

The dielectric strength of the interrupter also increases, and the

circuit is interrupted. Within the contacts in the open position, the

circuit voltage is withstood internally by the inter-contact gap

and externally by the insulating envelope.

The energy that is necessary for closing the circuit breaker is

provided by the closing spring. The energy storage can be done

by the motor or by the manual charging handle.

Motor spring charging

The energy charging mechanism consists of energy storing

motor, gear wheel, cam, holder and closing spring. When the

energy-storing motor (11) is charged, the pinion of output shaft

(12) that is connected to motor will rotateand drive the gear

��"=��

on the shaft move, which then drive the shaft to rotate, so that

draws out the closing spring (17) for storing energy. When the

block on the gear wheel is pushed away, the clutch is separated

��5��

mechanism in charged position, thus completing the charging

operation succeeds.

When energy is charged manually, the operator charges

the spring by operating the energy-charging handle on the

mechanism up and down repeatedly.

When the charging operation is completed, you can hear a 'click',

and the energy charging indicator (13) is switched over, as well as

the status of position switch (6), cutting the secondary charging

circuit supply to motor. The operating mechanism now is ready

for the next operation. (Figure 3)

When the closing circuit is powered, the closing coil is energized

and the holder (4) will rotate counter clockwise to break away

��"=��; ��

force from closing spring (17), will rotate clockwise,

to push the roller on the main shaft, which will move the main

shaft (10) in counter clockwise rotation. The main shaft moves the

connecting rod down through arm, so that the insulating rod (2)

sequences of opening and closing operations. Once the circuit

breaker is in closed position, the closing operation will be

prohibited.

When the circuit breaker is closed, the mechanism can be

charged for close, so that the circuit breaker can reclose

immediately after tripping.

When the breaker receives an opening command (the opening

push button is pressed or the tripping coil (16) is energized), the

tripping shaft will rotate clockwise. Under the action of opening

spring (3) and contact-compressing spring, main shaft will move

clockwise, and the insulating rod (2) will make the movable

indicator (9) will indicate 'open'. Meanwhile, the counter will record

the operation.

The follow interlocking facilities are

incorporated to ensure the safe operation

of the breaker. when the breaker is closed,

the withdrawable circuit breaker cannot

be racked between the service position

and test position.

When the earthing switch is in the

closed position, the withdrawable

circuit breaker cannot be racked into

the service position

When the withdrawable circuit breaker

is in service position, the earthing

switch cannot be closed

Correct installation is of primary

importance, the manufacturer’s

instructions must be carefully studied

and followed. It is good practice to use

gloves for handling the breaker during the

installation.

Please carry out installation and wiring

of breaker according to manual. Do not

place any foreign objects in the breaker or

modify it in anyway.

Check before installation

After the breaker is unpacked, check

the poles for any signs of mechanical

damage. The product nameplate and

^ ��

order. Check goods according with the

packing list.

Clean the insulating parts with a clean

dry cloth. Make sure the upper and lower

contact arms are clean and free of any

deformation caused by mishandling

during transport or storage.

Check the vacuum pressure in the vacuum

interrupter through power frequency

withstand voltage test. If it fails, please

The careful and professional

installation is a fundamental condition

for the failure free operation of the

circuit breaker

The circuit breaker should be

installed so that there are no external

forces applied to it from busbars or

mechanical supports

The busbar connection should not

cause any deformation to the breaker

terminals

Take note of supplied drawings for bolt

sizing and lengths

Use the standard bolts with strength

of class 8.8 and the disc springs to

tighten the bus bar (Table 1)

All commissioning and operation work

shall be carried out by persons who have

received professional training and are

familiar with operation of the breaker.

Necessary protective and preventive

measures shall be taken during work.

Use the product under normal working

Commissioning

Operation for withdrawable circuit breaker

Put the circuit breaker into test position

Connect the secondary wiring plug and

open and close the breaker several

times to ensure correct operation by

local and remote control

Insert the handle and rotate the racking

handle clockwise about 20 revolutions.

Upon the 'click', the withdrawable

circuit breaker will be in the service

position (Don't apply excessive force, to

avoid any damage)

Considerations

Check the circuit breaker for any

damage or any other dangerous

��$ ��

Wipe down the breaker, especially dirt

that may have accumulated on the

surface of the insulator. Especially the

dirt on the surface of insulation

The lifting hook of the circuit breaker

must be removed prior to operation

Check the primary and secondary

circuits as well as the earthing

Implement energy charged, opening

and closing operations. Manually

ensure the breaker is operating

correctly
