Beschreibung
Zusammenfassung:	A gas-insulated switching device includes: a vacuum valve having a movable contact provided on one side of a movable conductor and a fixed contact provided to a fixed conductor; an insulation rod connected to another side of the movable conductor led out from the vacuum valve through a bellows; an operation rod connecting the insulation rod and an operation device; an airtight container in which the insulation rod, the other side of the movable conductor, and the operation rod are accommodated; and an intermediate pressure chamber formed by communication between internal spaces of the bellows and the airtight container. A sliding contact member is provided to the other side of the movable conductor. The sliding contact member is connected, via the airtight container, to a main circuit conductor. A communication portion provided between the airtight container and the sliding contact member allows communication inside the airtight container.
