To provide a gas-insulation switchgear capable of appropriately discharging insulation gas.SOLUTION: A gas-insulation switchgear includes a container and a pressure discharging device. The container encapsulates a conductor and insulation gas inside. The pressure discharging device is provided at an opening of the container and can discharge the insulation gas from a discharge port to the outside of the container in response to pressure of the insulation gas. A vertical range that can be reached by a hand of a maintenance worker in a horizontal region into which the maintenance worker enters during electrification is taken as a work space. The discharge port is arranged so as not to face the work space.SELECTED DRAWING: Figure 1 【課題】絶縁ガスを適切に放出することができるガス絶縁開閉装置を提供することである。【解決手段】実施形態のガス絶縁開閉装置は、容器と、放圧装置と、を持つ。容器は、導体および絶縁ガスを内部に封入する。放圧装置は、容器の開口に設置され、絶縁ガスの圧力に対応して絶縁ガスを放出口から容器の外部に放出可能である。通電中に保守作業員が立ち入る水平方向の領域であって保守作業員の手が届く鉛直方向の範囲を作業空間とする。放出口は、作業空間と対向しないように配置される。【選択図】図１
