Claims

[Scope of claim for utility model registration] A substantially cylindrical tank placed on a cable support pedestal, whose lower part is covered with a board and whose upper part is covered with a lid,
Attach the cable head to the top of the board, connect the main circuit conductor on top of the cable head, and
A first disconnector that can connect and disconnect the main circuit conductor with other main circuit conductors connected to the main bus, and a second disconnector that can connect and disconnect the main circuit conductor and the lightning arrester installed in the tank. In a gas-insulated switchgear equipped with a disconnector and a grounding device for grounding the main circuit conductor, a group of stacked elements is installed at the apex of a triangle, and three movable contacts that also serve as lightning arrester terminals are installed. A gas characterized in that the lightning arrester and the second disconnector are configured by providing a fixed contact movably in a space surrounded by a group of elements and at a position where the movable contact is slidably inserted. Insulated switchgear.
