Abstract
Description
Claims (2)
- 차단기 동작코일의 단선 유무를 감지하기 위한 회로에 있어서,동작 코일과 직렬로 연결되어 상기 동작 코일의 정상 동작시에 발광하고, 단선시에 발광하지 않도록 저항과 LED가 직렬로 결합된 단선 감지부;상기 단선 감지부의 LED발광 상태를 감지하여 전기 신호를 발생하는 포토 커플러와 상기 포토 커플러에서 발생된 전기 신호에 의해 동작되는 릴레이를 포함하는 원격 감지부;상기 원격 감지부의 릴레이 동작에 따라 연동되는 스위치에 의해 동작되어 상기 동작 코일의 단선시에 경고 램프 및/또는 소리를 발생하는 경고부; 및상기 원격 감지부의 릴레이 동작에 따라 연동되는 스위치에 의해 동작되어 상기 동작 코일의 정상 동작 및 단선 여부를 기록하는 관리 서버를 포함하는 것을 특징으로 하는 차단기 동작 코일 감시 장치.
- 제1항에 있어서, 상기 원격 감지부는,상기 포토 커플러의 전기 신호는 트랜지스터의 베이스 단자에 연결되어 증폭되고, 상기 트랜지스터의 신호 증폭에 의해 상기 릴레이가 동작되는 것을 특징으로 하는 차단기 동작 코일 감시 장치.
