The present invention relates to an environmentally friendly insulated switchgear for an electric railroad, which adopts DRY-AIR gas, N_2 gas, fluorinated mixture gas, and the like without using SF_6 gas which is an insulator used in advance. Specifically, a disconnector and a circuit breaker are reduced and modularized. So, a space occupied by the disconnector and the circuit breaker is reduced, and space occupancy in an electric room is improved. Moreover, a distance from a manipulator is shortened, and manipulation operation of the manipulator is accurately transmitted to the disconnector and the circuit breaker. Therefore, a malfunction is reduced. Furthermore, the environmentally friendly insulated switchgear for an electric railroad can prevent the sudden malfunction caused by a worker by efficient arrangement.
본 발명은 기존에 사용되는 절연재인 SF6 가스를 사용하지 않고 DRY- AIR가스, N2가스, 불소계 혼합가스 등을 채용한 전기철도용 모듈형 절연개폐장치에 관한 것으로, 특히 단로기와 차단기를 축소 모듈화함에 따라 이들이 차지하는 공간을 축소시켜 전기실의 공간 활용도를 높였고, 조작기와의 거리를 좁혀 조작기의 조작 동작이 정확하게 단로기와 차단기에 전달되게 하여 오동작을 줄였으며, 효율적이 배치를 통해 작업자에 의한 불의의 오작동을 방지할 수 있게 한 전기철도용 친환경 모듈형 절연개폐장치에 관한 것이다.
