る請求項(1)記載の開閉装置。[Claims for Utility Model Registration] (1) In a switchgear in which at least a lightning arrester is housed in a metal container at ground potential, a first fixed contact part disposed on the live part side of the lightning arrester and a metal container at ground potential A second fixed contact part disposed on a ground conductor located in one end of which contacts and separates from the first fixed contact part, and the other end of which contacts and separates from the second fixed contact part, and at least the first fixed contact part. Fixed contact part or second
The movable contact part, which contacts the sliding contact part when in contact with the fixed contact part, is separated from the first fixed contact part and the second fixed contact part in an intermediate position by an appropriate distance necessary for insulation, respectively. The sliding contact portion is arranged so as to be able to move in a reciprocating straight line so as to be spaced apart, and the movable contact portion is in contact with the first fixed contact portion during normal energization, and the movable contact portion is in contact with the first fixed contact portion when the main circuit conductor is grounded. The movable contact portion is configured to be in contact with the second fixed contact portion and to be at an intermediate position between the first fixed contact portion and the second fixed contact portion during a withstand voltage test of the main circuit conductor. A switchgear characterized by: (2) The switchgear according to claim 1, wherein the metal container is filled with an insulating medium such as an insulating gas or an insulating oil.
