Claims (1)

  1. 교류전로(電路)에 삽입된 부하개폐 접점과, 이 접점에 흐르는 전류를 검출하는 번류기와, 이 변류기의 2차권선에 접속되어서 상기 변류기의 교류 2차전류를 단일방향 전류로 변환하는 정류회로와, 이 정류회로의 출력단자 사이에 접속된 직류 정전압(定電壓) 전원회로와, 상기 단일방향 전류에 비례하는 상기 전류검출 저항체의 전압강하를 증폭하는 차동증폭회로와, 상기 단일방향 전류의 소정의 크기에 대하여 소정의 시간지연을 발생시키는 시한(時限)회로와, 이 시한회로의 출력에 의해서 개방에서 폐쇄로 조작되는 개폐회로와, 이 개폐회로의 폐성(閉成)으로 전자(電磁)트립코일에 의해 구동되어서 상기 부하개폐 접점을 폐쇄에서 개방으로 하는 차단기구를 구비하고, 상기 시한회로는 상기 차동증폭회로의 출력신호를 받아서, 그 출력신호의 피크치전압으로 변환하는 피크치변환회로와, 상기 자동증폭회로의 출력신호를 받아서, 그 출력신호의 피크치전압으로변환하는 피크치변환회로와, 상기 실효치변환 회로로부터의 실효치전압과 피크치변환 회로로부터의 피크치전압이 입력되는 장한시(長限時)트립회로와, 이 장한시 트립회로에 입력되는 실효치전압을 피크치전압으로 전환하는 스위치와, 상기 실효치변환 회로의 출력 전압이 소정치 이상으로 되었을때 이것이 검출하여 또한 상기 스위치를 전환하여 상기 장한시 트립회로를 실효치변환 회로로부터 피크치변환 회로측에 접속하는 전환제어회로를 구비한 것을 특징으로 하는 회로차단기.
    ※ 참고사항 : 최초출원내용에 의하여 공개하는 것임.
