도1은 종래 가스절연개폐장치의 접지개폐기를 나타내는 구성도이다(개로 상태). 도시한 바와 같이, 접지개폐기(10)는 케이스(11)의 내부에는 개폐동작을 하는 가동자(12)와 이 가동자(12)의 통전 전류를 통전시키는 접촉자(13)와 이 접촉자(13)를 고정시켜 통전 전류를 케이스(11) 외부로 통전시키는 고정 플레이트(14)가 설치되고, 상기 가동자(12)의 일측(상측)단에는 상기 가동자(12)가 직선운동하 도록 슬라이딩하는 한편 회동하는 중간레버(15)가 힌지결합되며, 상기 중간레버(15)의 일측단에는 조작기 축(도시안됨)에 연결되는 조작레버(16)가 힌지결합되고, 상기 중간레버(15)의 타측단은 장홀(17a)이 형성된 가이드(17)에 의해 슬라이딩하게 되어 있으며, 상기 케이스(11)와 고정 플레이트(14)를 절연하는 절연체(18)와, 상기 케이스(11)와 통전부를 이어주는 접지 본드(Bond)(19)를 구비한다.1 is a configuration diagram showing a ground switch of a conventional gas insulated switchgear (open state). As shown in the drawing, the ground switch 10 includes a mover 12 which opens and closes the inside of the case 11, a contactor 13 which energizes a conduction current of the mover 12, and the contactor 13. A fixing plate 14 is provided to fix the current to the case 11 so that the energizing current is supplied to the outside of the case 11, and the movable plate 12 slides at one end (upper side) of the movable plate 12 so as to linearly move. Rotating intermediate lever 15 is hinged, one end of the intermediate lever 15, the operation lever 16 is connected to the manipulator shaft (not shown) is hinged, the other end of the intermediate lever 15 The metal sheet is slid by a guide 17 having a long hole 17a formed therein, an insulator 18 that insulates the case 11 from the fixing plate 14 and a ground bond that connects the case 11 and the energizing part. (Bond) 19 is provided.
