Claims

[Scope of utility model registration request]

A fixed current-carrying contact in a cylindrical case filled with an insulating gas, a hollow fixed arc finger contact disposed inside the fixed current-carrying contact and electrically connected to the current-carrying contact, and the current-carrying contact. A movable arc contact element is provided inside a cylindrical movable energizing contact element which is disposed so as to be able to freely approach and separate from the fixed arc finger contact element, and a movable arc contact element which is disposed so as to be able to freely approach and separate from the fixed arc finger contact element. In a gas insulated disconnect switch in which the movable arc contact is separated from the arc contact at the same time as the arc contact is separated, the movable arc contact has an arc-resistant member forming a tip and an electrically conductive an arc drive coil electrically connected between coil end rings connected to the arc drive coil, and an overvoltage between the opposing surfaces of the coil entry jig and the arc-resistant member electrically in parallel with the arc drive coil. A gap is provided to form a protective gap, and the foreboard fixed arc finger contact is provided with a plurality of slots in the axial direction to have spring properties, and one end is fixedly supported on the fixed side member on the inside, and the other side is fixedly supported on the fixed side member. A gas insulated disconnector characterized in that a magnetically permeable member is disposed inside the tip of a fixed arc finger contact.
