Abstract
Description
Claims (1)
- 모터(1)로 공급되는 AC전원의 상태에 따라 제어하는 모터 제어용 복합차단회로에 있어서, 번류기(1)에서 검출한 전류를 직류의 전압으로 변환시켜 소정의 비율로 분배한 분할 전압을 출력하는 전류-전압 변환부(3)와, 상기 전류-전압 변환부(3)로 부터의 분할 전압이 정격의 기준전압보다 큰가로 과전류의 여부를 판단하는 제1비교부(4)와, 영상변류기(5)에서 유기된 교류전압을 직류전압으로 바꾸면서 소정의 비율로 분배하여 출력하는 전압변환부(5)와, 상기 전압 변환부(6)로 부터의 분할 전압이 0V보다 큰가로서 지락 또는 단락의 상태를 판단하는 제2비교부(7)와, 상기 제1 및 제2비교부(4), (7)의 출력이 앤드게이트(A1)외 인버터(I)에 의해 반전되도록 한 인터페이스부(8)와, 상기 인터페이스부(9)로 부터의 출력에 따라 모터(1)로 공급 전원을 제어하는 릴레이부(5)들로 구성됨을 특징으로 하는 모터 제어용 복합차단 회로.
