Abstract
Description
Claims (1)
- 조절기(11)가 구비된 전기, 전자기기를 구성함에 있어서, 상호 직렬 연결된 상태에서 두 전선(A,B) 사이에 병렬 연결되어 교류전압이 공급될시 접지선이 위치에 따라 선택적으롱 점등되는 전원램프(L1,L2)와; 상기 전원램프(L1,L2)의 중앙 접점에 설치되어 전원전압 공급시 가상접지 기능을 수행하는 가상접지선(VGW)과; 상기 전원램프(L1,L2)의 점등여부에 따라 두 전선(A,B)중 어느선이 접지선인지를 검출하는 접지선 검출센서(1,2)와; 상기 두 전선(A,B)에서 영점전압을 검출하여 주는 영점전압 검출부(4)와; 상기 접지선 검출센서(1,2)의 출력신호를 선택적으로 출력시켜 차폐망(8)이 정확한 접지선에 연결되도록 하는 제어부(3)와; 상기 두 전선(A,B))과 영점전압 검출부(4)에 입력단자가 각각 연결되고 출력단자가 차폐망(8)에 공접되어 상기 제어부(3)의 출력신호에 따라 선택적으로 구동되어 차폐망(8)을 정확한 접지선에 연결시켜 주는 제1 내지 제3스위칭부(5-7)와; 각종 전기, 전자기기(100)내에 설치되어 기기내에서 발생되는 유해파의 방출을 차폐시켜 주는 차폐망(8)을 상호 연결 구성하여서 된 것을 특징으로 하는 접지선 검지에 의한 유해파 차단장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
