| Zusammenfassung: | The present invention relates to an earthing switch that can ensure sufficient switching performance regardless of the type of insulating gas. The earthing switch comprises: a fixed contact part which is fixed to the inside of an enclosure; a movable contact part which is disposed to face the fixed contact part, and has a hollow portion formed therein, wherein one end of the movable contact part is connected to a driving device and driven by the driving device, so that the other end is connected to or separated from the fixed contact part; and a piston part which is located within the hollow portion, and moves relative to the movable contact part. The hollow portion may extend along the longitudinal direction of the movable contact part, and both ends of the hollow portion in the longitudinal direction may be formed to be opened.
본 발명은, 절연가스의 종류에 상관없이 스위칭 성능이 충분히 확보될 수 있는 접지 개폐기에 관한 것으로, 외함 내에 고정된 고정 접점부; 상기 고정 접점부에 대향하도록 배치되고, 내부에 중공부가 형성되며, 일측 단부가 구동장치에 연결되어 상기 구동장치에 의해 구동됨으로써, 타측 단부가 상기 고정 접점부에 연결 또는 분리되는 가동 접점부; 및 상기 중공부 내에 위치되어, 상기 가동 접점부에 대해 상대이동하는 피스톤부를 포함하고, 상기 중공부는 상기 가동 접점부의 길이방향을 따라 연장되고, 상기 중공부의 길이방향 양측 단부는 개방되게 형성될 수 있다. |
