PROBLEM TO BE SOLVED: To allow for switching to a seal-off system, without decomposing the high-pressure gas container of a currently operating insulated switchgear of gas circulation system, while allowing low cost maintenance and management of apparatus including subsequent moisture control.SOLUTION: A gas-insulated switchgear includes a gas container, a supply and exhaust port, and an adsorber. The gas container is obtained by connecting a plurality of cylindrical members, having a flange at the end, by means of the flange. The supply and exhaust port supplies and exhausts gas to and from the gas container, and is provided on the peripheral surface of the cylindrical member. The adsorber is attached to the supply and exhaust port. The adsorber has a moisture adsorption chamber housing a moisture adsorbent.SELECTED DRAWING: Figure 1 |
