摘要： A circuit breaker of different interruption speeds, and a spring operation mechanism is standardized for designing and manufacturing the circuit breaker. The circuit breaker has a power transmission mechanism for driving a movable contact 63 and a fixed contact 64 and an interruption spring 26 that imparts a driving force to separate the contacts through the power transmission mechanism. A latch mechanism restricts movement of the power transmission mechanism, and a pull-out operation section releases the restriction of the power transmission mechanism by the latch mechanism. The pull-out operation section is arranged to oppose a first arm of a lever to rotate the first arm. The lever is arranged so that a tip of a second arm is able to engage with and rest on the latch mechanism, and release the restriction of the power transmission mechanism by the latch mechanism.

摘要： A gas-insulated apparatus is equipped with multiple sensors for sensing a partial discharge signal caused by a foreign substance, and a frequency analyzing section for analyzing the frequency of the sensed partial discharge signal. A defect type judging section estimates the defect type of the foreign substance from the signal obtained through the frequency analysis or from the voltage phase distribution of partial discharge synchronized with the frequency of the voltage applied to the gas-insulated apparatus, and a location determining section estimates the defect location and signal intensity from the multiple partial discharge signals. A defect size calculating section estimates the defect size for each defect type from the signal intensity and field distribution at the defect location. Dielectric breakdown risk evaluation is performed based on the defect size and type, and the insulation failure risk is diagnosed from the partial discharge.
