Claims (1)

  1. 열형 과부하 계전기로서,과전류가 흐를때 굽어지는 바이메탈을 구비하며;일단이 시프터와 결합되고, 바이케탈 굽힘시에 시프터를 통하여 상기 바이메탈에 의해 회전되는 해제레버를 구비하며;상기 해제레버의 타단과 결합하는 제 1 스프링과, 상기 제 1 스프링이 상기 해제레버의 회전에 의해 그 한계점을 지나 제 1 안정상태를 벗어나면,제 1 스프링을 제 2 안정사태로 보내주는 역할을 하는 제 2 스프링으로 구성된 스프링기구를 구비하며;그리고, 상기 스프링기구의 자유단과 결합하는 접점지지체를 수반하며, 상기 제 1 스프링이 제 1 안정상태 또는 제 2 안정상태로 왔을때, 회로를 연결하거나 차단하는 역할을 하는 접점장치를 구비하는 것을 특징으로 하는 열형 과부하 계전기.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
