Claims

[Scope of utility model registration request]

(1) In a gas-insulated switchgear in which a lightning arrester and a bushing are connected to the main circuit conductor via a T-shaped connecting conductor, the lightning arrester side is closer to the junction of the main circuit side conductor and the arrester side conductor in the connecting conductor. A gas insulated switchgear characterized in that a removable conductor that can be freely removed from the connecting conductor is provided in the section, and a hand hole is provided in the tank of the connecting conductor in accordance with the position of the removable conductor.

(2) The gas-insulated switchgear according to claim 1, wherein the lightning arrester is arranged parallel to the main circuit conductor and horizontally on the ground surface, and the lightning arrester side of the connecting conductor is bent in the horizontal direction toward the lightning arrester. .
