Abstract: A gas blast circuit breaker for high voltages has an elongated breaking chamber permanently filled with compressed gas which contains a power break with a movable contact. An operating device for the movable contact is positioned at one end of the breaking chamber. An exhaust channel runs through the breaking chamber with its outlet at the other end of the breaking chamber. A blast valve is mounted for closing and opening the outlet. The blast valve is actuated towards closing position by fluid under pressure from the breaking chamber, supplied through a passage leading by a first auxiliary valve. The blast valve is closed by the opening movement of the movable contact through a push rod which acts to open the first auxiliary valve when the contact opens. A second auxiliary valve connected to the outside and also operated by the push rod is opened when the breaker is closed so as to open the blast valve.

Abstract: A high voltage switching device is operated by a compressed gas valve having an electrodynamic operating means. The operating means comprises a stationary coil which is inductively connected to a short-circuit winding supported by the movable member of said valve. To operate the switching device a capacitor located at high potential is connected to said coil through a photoelectric switching member.
