摘要： Compact lightweight gas insulated switchgear which assures sufficient electrode fixing strength equivalent to the fixing strength given by brazing and is structurally simple and enables efficient arc rotation with low operating energy. In the switchgear, a movable arcing contact is located on a movable element, opposite to a fixed arcing contact and electrically connected to, or disconnected from, the fixed arcing contact as the movable element moves. The movable arcing contact includes, in order from its tip opposite to the fixed arcing contact, a first electrode as a convex hollow coaxial cylindrical electrode, hollow coaxial cylindrical first spacer, and second electrode as a hollow coaxial cylindrical electrode and has electric conduction means to connect the first and second electrodes electrically through the first spacer. The first and second electrodes are fixed through the first spacer by a fixing member having higher resistivity than the first and second electrodes.
