Description
Claims (3)
- 전기선로상에 설치되어 과부하나 사고전류의 발생시 전원을 차단하여 회로 및 부하기기를 보호하는 차단기에 부착되는 보조장치에 있어서,상기 차단기 프레임내에 설치되어 바이메탈의 변위에 따라 이동하는 시프터와,상기 보조장치 프레임내에 설치되어 상호 접촉에 의해 차단기가 트립되었다는 것을 외부에 신호로 전달하기 위한 고정대 및 가동대와,상기 보조장치 프레임내에 회전 가능하게 설치된 연동레버와,상기 시프터와 연동레버 사이에 설치되어 결상에 의해 시프터가 이동할 때 연동레버가 회전되게 하여 주는 연결대와,상기 연동레버에 근접 설치되어 정상 통전시 가동대의 이동을 구속하고 연동레버의 회전시 함께 회전하면서 가동대를 구속상태에서 해제하는 구동레버를 포함하여 구성된 것을 특징으로 하는 차단기의 결상 표시장치.
- 제 1 항에 있어서,상기 연결대는 일측에 돌기를 형성하고 이 돌기를 연동레버의 구멍으로 끼워 연결대와 연동레버가 연동되도록 한 것을 특징으로 하는 차단기의 결상 표시장치.
- 제 1 항에 있어서,상기 구동레버는 일측에 탄성력이 작용하는 걸림핀을 설치하고 연동레버의 회전시 연동레버가 걸림핀에 걸림에 따라 구동레버가 함께 회전되게 한 것을 특징으로 하는 차단기의 결상 표시장치.
