開閉装置。1. A gas insulated switchgear in which equipment necessary for configuring a switching circuit is housed in a container filled with insulating gas,
An opening is provided in a part of the container, an insulating spacer is attached to airtightly close the opening, and a fixed electrode for applying a test voltage is connected to a device under test to which a test voltage needs to be applied. A movable electrode for applying a test voltage, which is disposed at a position facing the opening and comes into contact with and separates from the fixed electrode for applying a test voltage, hermetically penetrates the insulating spacer and is slidable in an airtight manner over the fixed conductor. A gas insulated switchgear, characterized in that the gas insulated switchgear extends through the container and is supported so as to be operable from the outside of the container.
