Vacuum Circuit Breaker Instruction Manual

2.3 Multiple Auto-Reclosing

HVF circuit breakers are capable of auto-reclosing and 

can also be used for multiple reclosing for the following

operating sequence

O-0.3s-CO-3min-CO-15s-CO.....  (O: tripping; C: closing)

2.4 Interlock Mechanism of the Draw-Out Type Breaker

The draw-out type circuit breaker has an interlock

mechanism which prevents trouble due to misoperation.

The sensing parts check the position of the circuit breaker

and prevent it from closing if the associated disconnector is

not allowed for safe operation.

2.5 Closing (Y9) and Anti-Pumping (K1)

When closing, authorization is applied through terminals 

6 & 7 Solenoid Y9 fress the closing spring, and thus closes

the circuit breaker electrically.

Immediately after the breaker closes, Aux. S/W, S1 opens

the circuit of closing, and limit switch S3 and anti-pumping

relay K1 switch affect to Y9 so that they can not be

reactivated until the continuous closing command is

interrupted. Thus the breaker can meet the IEC

requirements for anti-pumping and trip-free opeation.

At the same time, the contact pressure spring is

compressed properly to maintain sufficient contact

pressure on the moving contact of the vacuum interrupters

while the breaker is in the closed position, and the tripping

spring is compressed for the opening operation.

2.6 Open Solenoid (Y1)

When the opening command is applied, the tripping spring

is unlatched by the trip solenoid Y1 and the force turns the

torque to rotate the brake shaft to make the opening

position. Immediately after the breaker is open, the

indicator displays the open state and Aux. S/W, S1 open

the opening circuit.

2.7 Auxiliary Switch (S1)

The standard auxiliary contacts for external connection are

composed of 4NO+4NC. These contacts are wired to the

control jack (XO).

Rated Insulation Voltage: AC/DC 250 V

Continuous Current: 10 A

Making Current: 30 A

Switching Current: 2 A at DC 220 V, 

τ

=20 ms

The maximum connection 10NO+10NC is available on request.

2.3 다중 재투입

HVF 차단기는 재투입 기능이 있으며, 또한 다음의 동작 스퀀스에 따라

다중 재투입으로도 사용될 수 있습니다.

O-0.3s-CO-3min-CO-15s-CO.....  (O; 트립, C; 투입)

2.4 인출형 차단기의 인터록 장치

인출형 차단기는 오동작으로 인한 사고를 막기 위해 인터록 장치를

구비하고 있습니다.

이 장치는 차단기의 위치를 파악하여 차단기가 안전한 위치에 있지

않을 때는 차단기의 투입이 불가능하게 합니다. 

2.5 투입(Y9)와 재투입방지 회로(K1)

표준회로 6, 7번 단자에 규정 전압의 투입 신호가 인가되면, 

솔레노이드 Y9가 동작하여 차단기가 전기적으로 투입되게 됩니다.

차단기가 투입되자마자, 보조접점 S1은 투입회로를 개방시키고, 

리미트스위치 S3과 재투입 방지 릴레이 K1은 연속 투입 지령이

끝날 때가지 Y9가 다시 동작되지 않도록 합니다.

따라서 차단기는 IEC에서 요구하는 재투입 방지와 트립 방지 기능과

일치합니다.

동시에 Contact Pressure Spring은 차단기가 투입상태에서 진공 밸브의

가동접점에 적절한 접촉압력을 유지시키기 위해 압축되며, 트립 스프링도

다음의 개극 동작을 위해 압축되게 됩니다.

2.6 트립 솔레노이드(Y1)

개극 신호가 인가되면 트립 솔레노이드, Y1은 트립 스프링의 랫치를

해지함으로 Breaker Shaft가 회전하여 차단기가 개극 되도록 합니다. 

차단기가 개극되면 개폐표시기는 Open 상태를 표시하고 보조접점 S1은

개극회로를 개로시킵니다.

2.7 보조 스위치(S1)

외부의 연결을 위한 표준 보조접점은 4NO + 4NC로 되어 있으며, 

이 접점들은 플러그 컨넥션(XO)에 연결되어 있습니다.

�정격절연전압 : AC/DC 250V

�연속전류 : 10A

�투입전류 : 30A

�개폐전류 : 2A (DC220V, τ=20ms에서)

�추가 접점이 요구되는 경우 최대 10NO+10NC까지 가능합니다.

Misoperation or carelessness may result in
serious injury or property damage.

With the  breaker closed, the draw in & out operation is
impossible. Do not push too hard on the breaker under
improper condition.

오조작, 또는 부주의가 중상 혹은 재산피해을 일으킬 수 있습니다.

차단기가 투입된 상태에서는 인입이나 인출이 불가능합니다.
잘못된 방법에서 차단기의 인입과 인출을 무리한 힘으로 동작
시키지 마십시오.
