Abstract

본 발명은 가스절연 부하 개폐기와, 이 개폐기 이용한 잔류전류의 접지방법에 관한 것으로, 종래에는 가스 개폐기를 개방한 상태에서 충전전류를 방전시키는데 많은 위험부담이 따라 작업자의 안전을 도모하기가 어려웠고, 이에 따라 안전사고가 빈번하게 발생되는 문제가 있었다. 이에 본 발명은 단일 용기 내부에 전류를 공급하는 전류공급용 고정접점과, 전류를 방전시키는 접지용 고정접점을 형성하고, 가동가능하게 설치되어 상기 전류공급용 고정접점과 접지용 고정접점 사이를 이동하는 전류개폐수단을 구비하여 가스충진상태에서 전류의 공급 및 중단과 아울러 접지기능을 수행하도록 구성한 것으로, 접지 및 충전전류의 방전이 간편하게 이루어짐과 아울러 접지작업이 안전하게 이루어져 작업자의 편리를 도모하고, 작업에 따른 위험부담을 덜어주도록 한 효과가 있으며, 또한, 신설 또는 증설된 지중케이블의 포설상태를 별도의 추가작업 없이 테스팅할 수 있도록 한 것이다.The present invention relates to a gas insulated load switch and a grounding method of the residual current using the switch, and in the related art, it is difficult to promote the safety of the operator due to the high risk of discharging the charging current while the gas switch is opened. Accordingly, there was a problem that safety accidents occur frequently. Accordingly, the present invention forms a fixed contact for supplying current and a fixed contact for grounding to discharge current in a single container, and is movable to move between the fixed contact for current supply and the fixed contact for grounding. It is designed to perform the grounding function as well as supplying and stopping the current in the gas filled state by providing the current switching means. It has the effect of reducing the risk according to the, and also, it is possible to test the installation status of the new or expanded underground cable without any additional work.
