Abstract
1394547 Gas blast switches SIEMENS AG 25 April 1973 [25 April 1972] 19750/73 Heading H1N In a high voltage electrical switch of the puffer type wherein two fixed contacts shaped to define nozzles 3a, 4a for the flow of arc quenching SF 6 gas co-operate with a movable bridging contact 7 carrying an auxiliary contact ring 9 of graphite, and wherein the moving contact, when the switch opens, moves in conjunction with a piston arrangement to compress the arc quenching gas, the auxiliary contact ring is so retained in the movable bridging contact assembly by resilient electrically insulating material 10 that when the switch is open it is contacted by lamellae of the movable contact. These lamellae are forced into contact with the auxiliary contact ring by means of springs controlled by camming surfaces 8.
