Abstract (en)
[origin: WO9912177A1] During the breaking action of an electric high voltage switch, a quick and high compression of an extinguishing gas should result in order to effectively extinguish an electric arc. During said breaking action, a high and quick compression of the extinguishing gas is achieved by means of a first (6) and second compression piston (7) of a piston cylinder arrangement (5, 6, 7) which move in opposite directions. The breaking movement of an actuatable contact part (19) is utilized in order to simultaneously operate the first compression piston (6) in the direction of the actuator (9) breaking movement and to actuate the second compression piston (7) in an opposite direction to the first compression piston by means of a shape (16) and a stationary mounted lever (14).
