摘要： PROBLEM TO BE SOLVED: To reduce the size of a gas-insulated switchgear for effective utilization of the space of power plant/substation and improved economy. SOLUTION: The gas-insulated switchgear comprises a fixed contact piece and a movable contact piece which is attachable/detachable from the fixed contact piece. The identical buffer device is used for braking operation of the movable contact piece in both cut-off operation and throw-in operation of the movable contact piece.

摘要： PROBLEM TO BE SOLVED: To provide a gas-insulated switch gear capable of stably supporting and fixing its drive operating device, even if a larger drive operating device is used as the size of the gear is increased and so as the required power, which solves such a problem with a conventional gas-insulated switch gear using a flange arranged at a side of a movable contact of the drive operating device unit as a structure for supporting and fixing the unit, that the overall size is increased, because many reinforcement parts are necessary to reinforce the upper cantilever supporting structure.
SOLUTION: An output shaft of a hydraulic operation drive device and a driving shaft of a movable contact of the gas-insulated switch gear are arranged in a line. A longitudinal shaft of a pressure storage device using air as a pressure storage source is arranged in parallel with the output shaft of the hydraulic operation drive device. A high pressure block equipped with a hydraulic line for supplying a high pressure operating fluid from the pressure storage device to the hydraulic operation drive device, is arranged perpendicular to the two types of shaft to support and fix the hydraulic operation drive device.
