Title: (EN) Tank-type vacuum interrupter
(ZH) 箱型真空断路器
Abstract: front page image
(EN) In order to obtain a tank-type vacuum interrupter for which a vacuum valve arranged within a pressure tank can be replaced quickly in a small work space with the interrupter in the mounted state, a tank-type vacuum interrupter is equipped with: a pressure tank; an insulating frame supported in a detachable manner on a supporting body within the pressure tank by means of a coupling part; a vacuum valve supported by the insulating frame and having a fixed electrode and a movable electrode; a fixed-electrode-side terminal connected to a bushing-terminal-side internal conductor by means of a connecting part so as to be capable of contact/separation; a movable-electrode-side terminal connected to a bushing-terminal-side internal conductor by means of a connecting part so as to be capable of contact/separation; and an insulating rod, the inner end of which is coupled to the movable electrode in a detachable manner by means of a coupling part, and the outer end of which is coupled to an opening/closing mechanism that opens/closes the contacts of the fixed electrode and the movable electrode. A unit structure is formed by the vacuum valve, the fixed-electrode-side terminal, the movable-electrode-side terminal, and the insulating frame, and the unit structure can be removed or attached by disconnecting the connecting parts and the coupling parts.
