Claims (1)

누전차단 회로를 구비한 누전 차단기에 있어서, AC 전원 측에포로 커플러를 설치하면서, 양방향 포로다이오드를 병렬 접속시키고, 그 일측이 바리스터에 연결되게 하고 타측이 전류 제한 저항에 의하여 AC 전원선에 연결되게 하며 이버터가 누전 검출 신호를 상대 변환하도록 집적회로와 비교기의 비반전 단자사이에 접속되게 하고, 비교기에는 그의 반전 단자에 클램프 다이오드를 접속하며 비반전단자에 다이오드를 접속시키고 동시에 다이오드와 캐패시터를 병렬로 접속하므로, 비교기가 소정 지연 시간 펄스폭을 가진 단일 펄스를 발생시키는 펄스 발생기로 구성하게 되고 비교기의 출력 단자측에 AND 게이트를 연결하여 누전시 누전차단기의 동작 상태 유무를 판단하게한 동작 시험 회로로 이루어진 누전 차단기.In an earth leakage circuit breaker having an earth leakage circuit, the bidirectional pore diodes are connected in parallel, and the other side is connected to the varistor and the other side is connected to the AC power line by a current limiting resistor while installing the captive coupler on the AC power side. The inverter is connected between the integrated circuit and the non-inverting terminal of the comparator so as to relatively convert the earth leakage detection signal. The comparator connects a clamp diode to its inverting terminal, a diode to the non-inverting terminal, and simultaneously parallels the diode and the capacitor. Operation test circuit is composed of a pulse generator for generating a single pulse having a predetermined delay time pulse width, and by connecting the AND gate to the output terminal side of the comparator to determine the operation state of the ground fault breaker Earth leakage breaker. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
