HVF Series

Hazardous High Voltage will cause serious injury,
property damage, or death.

Before inserting or withdrawing, the breaker should be
open. Before turning the handle, lift up the interlock
handle. If excessive power is applied to the handle
when the breaker is closed or the interlock handle is
not lifted up, it can cause damage to the breaker.

Make sure that the breaker and cradle have same
rating when inserting and withdrawing the breaker.

The sticker and name plate with rating are attached on
the product.

고전압은 중상, 재산피해, 혹은 사망을 일으킵니다.

차단기를 인입, 인출시키기 전에 차단기는 반드시 트립(OPEN)
상태이고, 인출입 핸들을 돌리기 전에 Interlock lever는
손으로 들어 올려진 상태이어야 합니다.
차단기가 투입상태이거나 인터록 핸들이 올라가 있지 않았을 때,
무리하게 힘을 가하여 돌릴 시에는 제품의 파손을 가져올 수
있습니다.

차단기와 크레들의 사양이 일치하는지 반드시 확인하여 주십시오.

크레들과 차단기에 제품의 사양이 표시되어 있습니다. 
반드시 확인 후 사양이 일치하도록 하십시오.

Excessive weight can cause serious injury or damage.

To avoid this situation, DO NOT transport the breaker
on a lifting facility in the raised position

과도한 무게가 나가는 제품은 심각한 인명피해, 기타 사고를
일으킬 수 있습니다.

높게 올려진 상태에서 차단기를 이동하지 마시고, 절대 차단기
밑에 서있거나 지나가는 일이 없어야 합니다.

4.3.1. ES/FS Type 

1) VCB 상태점검

배전반 또는 Cradle에 설치하기 전 VCB가

“OPEN”되었는지 반드시 확인하십시오.

2) Disconnection(또는 Test) 위치로 장착

차단기를 Cradle의 Disconnection(또는 Test)
위치에 밀어 넣습니다. 이때 Interlock Lever를
충분히 눌러 삽입이 원활히 이루어 지도록
합니다. 또한, 그림 4-8과 같이 Truck Wheel이
정확히 안착되었는지 확인하여야 합니다.

3) Connection 위치로 장착

차단기가 개극 되었는지 확인한 후, 
수동 인출입 핸들을 삽입하십시오. 
Interlock Lever를 충분히 누르고 차단기가
Connection 위치로 이동하도록 인출입 핸들을
차단기 방향으로 밀어 삽입합니다.
그림 4-6 하부 사진과 같이, 차단기가
Connection 위치에 정확히 장착되면
Interlock Pin이 자동으로 떨어지면서
Interlock Lever가 원위치로 복귀합니다. 
이때 Interlock이 적절히 이루어지면
Locking 되는 소리(부딪히는 소리)가
발생하오니 반드시 확인하십시오.
또한, Interlock Lever를 2~3회 이상 눌러
자연스럽게 동작하는지 반드시 확인하십시오.

4.3 HVF 차단기의 인출입 방법

현대 HVF Type 진공차단기의 인출입 장치는 고객의 요청에 따라

여러 종류가 제작될 수 있습니다.

다음은 당사에서 표준으로 사용하고 있는 모든 방식의 인출 장치에 대한

취급 설명입니다. 표준 Type이 아닌 경우에는 당사로 문의하십시오. 

4.3.1. ES/FS Type 

1) Check the condition of the breaker.

Check the breaker is opened before
inserted into the switchgear or cradle. 

2) Insertion to the disconnection position

Insert the breaker to the cradle at
disconnection (or test) position. 
At this time, push down the interlock
lever fully for easy insertion. Check that
the wheels of the breaker are 
inserted into the cradle as fig 4-8.

3) Insertion to the connection position

After checking to see if the breaker is
opened at the disconnection position,
insert the crank handle to the hole to
draw in and out.  Push the interlock down
fully. Then, push up the crank handle to
the breaker so that the breaker moves to
the connection position.
If the breaker is in the connection
position as in fig 4-6b, the interlock pin
drops down into the lock hole and
interlock lever comes back to the initial
position.
At this time, check that interlock pin
makes the locking sound 
"knocking or click".
Finally, push the interlock lever times to
check the movement.
