ガス絶縁開閉装置。[Scope of claim for utility model registration] (1) A movable side electrode and a fixed side electrode are provided in a grounded container filled with insulating gas, and a movable contact connected to an opening/closing mechanism can be connected and separated between the two electrodes. In a gas-insulated switch equipped with a buffer spring having a spring load that balances or reduces the weight of the movable part of the switch, the spring force of the buffer spring is adjusted from the outside. A gas insulated switchgear characterized in that it is equipped with an adjustment device that can. (2) The adjustment device includes a flange that fixes one end of the buffer spring, a nut that regulates the position of the flange, and a threaded portion that is attached to a shaft provided on a drive device that drives the switch. A gas insulated switchgear according to claim 1, characterized in that the gas insulated switchgear is constituted by a joint having: (3) The gas insulated switchgear according to claim 2, wherein the adjustment device adjusts the spring force of the buffer spring by rotationally moving the joint. (4) The gas insulated switchgear according to claim 2, wherein the adjustment device adjusts the spring force of the buffer spring by rotationally moving the nut.
