4.3 Operation Mode
1) Charging
When the charging mechanism
is activated by hand or motor
(31), the charging shaft (11-1)
turns by the gears and the
driver (11-2) so that the closing
spring (12) is tensioned. When
the closing spring is fully
tensioned, the closing pawl
(11-3) makes the closing spring
be latched.
2) Closing
When closing command is
applied, the closing spring is
unlatched by the activation of
the closing pawl. Through the
energy from the discharging of
the closing spring, the coupling
bar is powerfully pushed down
via the charging shaft and the
cam.
Consequently, the breaker shaft
is turned until the moving
contact is fully closed and
latched by the trip pawl (25-1).
At the same time, the contact
pressure spring (49) is
compressed to insure sufficient
contact pressure on the moving
contact while the breaker is in
the closed position, and the
tripping spring (13) is
compressed for the opening
operation.
3) Recharging
After the closing operation, the
closing spring can be
immediately recharged bya
motor (31) or hand so that the
breaker immediately re-closes
in case the closing authorization
re-closes is applied.
4) Opening
When opening command is
applied, the tripping spring is
unlatched by the activation of
the trip pawl, and the breaker
shaft is returned to the open
position.

4.3 동작 설명
1) Charging
수동적인 방법이나 모터(31)에 의해
closing spring(12)이 차지되면,
charging shaft(11-1)가 gear나
11-3
driver(11-2)에 의해 돌아가서 투입
스프링을 압축합니다. closing spring
11
이 완전히 압축되면, closing pawl
33
(11-3)은 closing spring이 풀리지
25-1
않도록 고정시킵니다.
16
2) Closing
투입지령이 들어오면, closing spring
이 closing pawl에 의해 압축을 풀게
됩니다. 이 에너지에 의해 coupling
bar가 charging shaft와 cam을 통하
여 세게 아래로 내려가게 됩니다.
결과적으로 breaker shaft(16)는
moving contact가 완전히 닿을 때까
지 회전하게 되며, trip pawl(25-1)에
의해 멈춰집니다. 동시에 contact
pressure spring(49)은 차단기가 투입
상태에서 moving contact에 적정
압력을 주기 위해 알맞게 압축됩니다.
trip spring(13)은 opening 동작을
위해 압축됩니다.
3) 재투입 대기
투입 동작 후에, closing spring이
모터나 수동으로 다시 압축될 수 있
습니다. 이는 재투입 지령이 내려오면
다시 재투입하기 위해서 입니다.
4) 트립
트립 지령이 내려지면, tripping
spring이 trip pawl에 의해 압축이
풀어지고, breaker shaft는 개극 위치
로 돌아오게 됩니다.
