Abstract:
1. A switch comprising: a hermetic vessel filled with an insulating medium; an insulating spacer dividing the hermetic vessel into a first hermetic space and a second hermetic space; a fixed electrode penetrating through and fixed to the insulating spacer; a first conductor led into the first hermetic space; a second conductor led into the second hermetic space; a first movable electrode connected to the first conductor directly or via another member, the first movable electrode movably provided in a vacuum vessel disposed in the first hermetic space so as to abut on/separate from the fixed electrode; a second movable electrode connected to the second conductor directly or via another member, the second movable electrode being provided in the second hermetic space so as to be movable in a first direction to become apart from the fixed electrode and in a second direction opposite the first direction; an opposed electrode slidably provided in the fixed electrode to face the second movable electrode so as to separate from the second movable electrode in an open state and so as to be in contact with the second movable electrode in a closed state; a first driver configured to generate a driving force for moving the first movable electrode so as to separate the first movable electrode from the fixed electrode when breaking a circuit between the first conductor and the second conductor from each other; a second driver configured to generate a driving force and moves the second movable electrode in the first direction when performing an opening operation; and a driving force transmitting mechanism configured to move the opposed electrode in the second direction by converting a direction of the driving force for moving the second direction opposite the moving direction of the second movable electrode when the second driver generates the driving force for moving the second movable electrode in the first direction.
