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 lightning arrester, one end of which is fixed to a main circuit conductor, is disposed at the other end of the lightning arrester. a fixed contact portion and a second fixed contact portion disposed on the main circuit conductor are arranged to face each other,
A sliding contact portion connected to a ground conductor is disposed between the first fixed contact portion and the second fixed contact portion and on the same axis, and one end portion is connected to the first fixed contact portion. a movable contact that contacts and separates from the second fixed contact portion and contacts the sliding contact portion when the other end portion contacts and separates from the second fixed contact portion and is in contact with at least the first fixed contact portion or the second fixed contact portion; disposed on the sliding contact portion so as to be capable of reciprocating linear movement at intermediate positions so as to be spaced apart from the first fixed contact portion and the second fixed contact portion by appropriate distances necessary for insulation, respectively; During normal energization, the movable contact section contacts the first fixed contact section, and when the main circuit conductor is grounded, the movable contact section contacts the second fixed contact section, and the withstand voltage test of the main circuit conductor is performed. An opening/closing device characterized in that the movable contact portion is sometimes located at an intermediate position between the first fixed contact portion and the second fixed contact portion. (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.
