摘要： A puffer type gas circuit breaker has a piston, which is connected with a center shaft via a link mechanism. At an initial stage of an interruption operation, the link mechanism drives a puffer cylinder and the piston both in an interruption direction while maintaining an almost constant distance therebetween. Even when a pressure rise occurs in a compression chamber by the heat of an arc generated in accordance with opening between a fixed arc contact and a movable arc contact, the pressure rise does not become an operation counterforce to an operator. At a final stage of the interruption operation where the fixed arc contact is removed from a throat of an insulating nozzle, the link mechanism drives the piston in an almost stopped status.

摘要： A current limiter used for stable control of an electric power system, and particularly applied to a high voltage of the electric power system, has a reduced voltage for suppressing the overcurrent of the electric power system. The current limiter is not enlarged so that the current limiter secures the insulation of the voltage withstanding level, and the current limiter is easy to be introduced to the system. A limiting device is inserted between a low potential terminal of a winding of a star-connection of a three-phase transformer that has at least one winding of the star-connection and a ground point.

摘要： A gas insulated switching apparatus has lightning arrestors in a line side unit. Each lightning arrestor is mounted to be moved linearly into and out of connection with a corresponding conductor. Specifically, the cover which supports the lightning arrestor is disposed beneath the bottom plate of the vessel of the line side unit. The lightning arrestors are connected to a monitor of an operating device beneath the line side unit. Since the lower portion of the lightning arrestors are connected to the monitor, the length of the connection lines is made sufficiently short.
