2.1 사용 조건

1) 사용 고도 : 1000m 이하

2) 상대 습도 : 95% 이하

3) 주위 온도 : MAX 40℃ / MIN -5℃

2.2 모터 동작

HVF VCB는 전동 스프링 방식의 에너지 저장형 기구부를 가지고

있으므로 투입 스프링이 완전히 차지된 후 투입 동작이 가능합니다.

표4에서 동작 중 모터의 전류 소비치를 나타내었으며, 돌입전류는

아주 짧은 시간만 지속하므로 무시될 수 있습니다.

표준회로 1, 2번 단자에 규정 전압이 인가되면 모터(M1)에 의해 투입

스프링이 인장되어 차지가 완료됩니다. 그리고 LINK에 의해 작동되는

리미트 위치 S21, S22에 의해 모터의 구동은 정지되고, 그림 1과 같이

스프링 표시기는“SPRING CHARGED”

를 표시합니다.

차지가 완료된 차단기는“트립-투입-트립”

의 동작을 연속적으로 할 수

있으며 트립 동작 후 지체 없이 다음 투입 및 트립 동작이 가능합니다.

Vacuum Circuit Breaker Instruction Manual

2.1 Service Condition

1) Site altitude: Less than 1000 m

2) Relative humidity: Less than 95%  

3) Ambient temperature: MAX 40°C / MIN -5°C

2.2 Motor Drive

HVF VCB have motor-spring type stored-energy operating

mechanism. The closing operation can be done only after

the closing spring is charged. 

Consumption during the operation is shown in Table 4, and

the inrush current may be disregarded since it lasts for only

a brief period.

The closing spring is fully tensioned by motor (M1) with the

rated voltage applied through terminal No.1 & 2 of standard

control circuit. Then the limit switch (S21, S22) stops the

motor, and the spring indicator shows "SPRING CHARGED"

by link activation as shown in Fig.1. The charged VCB can

carry out the open-close-open sequential operation and

also the next close-open operation without delay.

Consideration of site altitude!

If the site altitude is higher than 1000 m, dielectric
strength of the breaker will be reduced according to
the altitude. Therefore, the values of power frequency
withstand voltage and lightning impulse withstand
voltage should be selected.

Rated withstand voltage according to rated voltage

X k (k: Refer to table 2-1.)

For higher humidity, it is required to use a heater in the
switchgear to prevent dewdrops on the insulation
material and the consecutive decrease in dielectric strength.
