Abstract:
1. A gas circuit breaker comprising: a sealed vessel with an insulating gas filled therein; an operation device case; an interrupting unit provided inside the sealed vessel, the interrupting unit including a fixed part and a movable part capable of parting from or coming in contact with the fixed part; a high-voltage conductor coupled to the movable part; an interrupting-unit side insulating rod attached to the movable part, the interrupting-unit side insulating rod moving the movable part in a closing direction and an interrupting direction; an electric actuator including a mover, the mover linking to the interrupting-unit side insulating rod inside the operation device case; a capacitor electrically coupled in parallel to the interrupting unit inside the sealed vessel; a movable contact electrically coupled to the capacitor; and a capacitor-side insulating rod attached to the movable contact, wherein the interrupting-unit side insulating rod or the mover has an engaging part inside the operation device case, wherein the capacitor-side insulating rod has a retaining part to be engaged with the engaging part, the retaining part being located at a position on a side of the engaging part, farther away from the interrupting unit, and wherein a closing-spring is provided so as to link the retaining part with an end of the sealed vessel, adjacent to the operation device case.
