Description
Claims (4)
- 그 자체에 접지단자가 마련된 전기적 부하, 그리고 이들 부하를 제어하는 마이크로컴퓨터를 포함한 제어장치를 구비하여서 된 전기제품의 누설전류 검출장치에 있어서, 상기 접지단자 및 상기 제어장치에 접속되어 상기 전기적 부하에서의 누설전류를 검출하기 위한 포토커플러가 구비된 누설전류 검출수단과, 상기 누설전류 검출수단이 동작될 때 누설전류 유무의 신호를 상기 제어장치에 출력하는 신호발생수단과, 상기 신호발생수단에서 출력되는 누설전류 검출신호에 의해 상기 전기적 부하에 공급되는 전원을 차단하는 스위칭 수단을 구비하여 된 것을 특징으로 하는 누설전류 검출장치.
- 제1항에 있어서, 상기 신호발생수단이 복수의 전압분배 저항기를 구비하여서 된 것을 특징으로 하는 누설전류 검출장치.
- 제1항에 있어서, 상기 스위칭 수단이 상기 제어장치에 의해 동작되어 정상전원시는 온상태로 누설전류시는 오프상태로 제어되는 릴레이인 것을 특징으로 하는 누설전류 검출장치.
- 제1항에 있어서, 상기 모터와 전기부하에서 누설전류가 발생시 경보를 발생하는 경보발생수단이 더 마련되어 있는 것을 특징으로 하는 누설전류 검출장치.
