Claims (1)

  1. 개폐기에 전압이 인가되었을때 여자되는 코일과, 이코일의 여자에 의하여 생긴 자속통로를 형성함과 동시에 개폐기의 트립기구와 계합하게 장설된 가동철실과, 이 가동철심에 대응되게 설치되어 코일의 여자에 의하여 가동철심과의 사이에서 흡인동작하는 고정철심과 개폐기의 투입동작에 선행하여 축세되어서 개페기에 인가되는 전압이 소정치 이하로 되었을 때 가동철심을 고정철심에서 이격하는 방향으로 구동시키는 구동스프링과, 구동스프링의 축세후 개폐기의 투입 동작시까지, 개폐기에 인가되는 전압의 크기에 관계없이, 구동스프링의 축세상태를 유지하는 기구등을 구비하여서된 부족전압 트립장치.
