摘要： A metal-clad isolator switch for multiple interruption divided in two parts insulated from each other and comprising means for connecting the interconnected movable switching contacts of the isolator switch with earth and a selectively operating signalling and protecting system which selectively indicates, when and in which one of the isolator switch parts an unwanted earthconnection occurs.

摘要： Metal clad gas blast circuit breaker which is exclusively adapted to interrupt a circuit, the switching element thereof being accommodated in a metal casing containing high-pressure and low-pressure compartments filled with insulating gas under overpressure, said circuit breaker comprising a safety valve and means to control said valve in such a manner, that the overpressures in said compartment can never fall below predetermined values.

摘要： A circuit-breaker is provided with relatively movable contacts and an actuating rod is attached to one of the contacts to effect separation of the contacts and opening of the circuit-breaker. The contact assembly is housed within an outer chamber which is subjected to insulating gas under high pressure and the contact assembly forms an inner chamber which, when the contacts are closed, is isolated from the outer chamber and which is vented to a pressure lower than the pressure in the outer chamber. A small net force acts on the movable contact to which the actuating rod is attached to maintain the contacts in closed condition. When the contacts are closed, the pressure differential existing between the outer and inner chambers is used in substantially balancing fashion and additional means is provided for cooperating with this differential pressure effect to establish the small net force serving to maintain the contacts in closed condition. When the contacts are open the pressure differential disappears and full pressure balance is effected so that both upon initial opening and continued opening movement as effected by the actuating rod, the actuating rod is subjected to very little mechanical stress. The opening of the contacts opens a valve formed between separable contacts and communicating the inner chamber with the outer chamber and allowing the insulating or extinguishing gas to rush past the contacts and axially through at least one of them for extinguishing the arc produced by opening of the contacts.

摘要： An electric switch having an axially movable switching contact and a resilient annular fixed contact. The fixed contact is in permanent contact with said switching contact and consists of a zigzag folded metal strip surrounded and supported by an annular holder. The metal strip is bent in the shape of a ring which snugly encloses the switching contact and is constituted by a circular series of pairs of contact lips.

摘要： A metal-clad isolator switch for high voltage, comprising fixed contacts, movable switching contacts cooperating with said fixed contacts and at least one earthing switch, of which the fixed contact is attached to the envelope of the isolator switch and the movable contact is carried by the holder of the movable switching contacts of the isolator switch, said movable earthing contact being directly mechanically driven and directly mechanically locked in either end position by a movable switching contact of the isolator switch.

摘要： An electric switch having an axially movable switching rod and a fixed contact which is in permanent contact with said switching contact. The fixed contact comprising a zigzag folded metal contact strip which is bent in the shape of an uninterrupted ring. The inner circumference of said ring is bent in the shape of longitudinally split tubes extending in the direction of the width of said strip and interconnecting the parts of the folded strip that adjoin each other at said inner circumference.
