DOUBLE-PUFFER-TYPE COMPRESSED-GAS CIRCUIT-INTERRUPTER CONSTRUCTIONS

Gas blowing switch with double circuit opening including a pair of separate fixed contact structures, a pair of separate mobile structures, one of said fixed contact structures cooperating with one of said mobile contact structures to establish an arc therebetween, a device that electrically connects the two moving contact structures in series to form a pair of arcs located in series to interrupt high voltage line circuits, a pair of laterally separated blow type interruption structures each including an element of piston and a drive cylinder element that can be moved relative to one another, a common drive rod, a device that mechanically connects one end of said common drive rod to each of the two interruption structures of the type of blown apart laterally to produce simultaneous movement or of said element of each pair of interruption structures of the blow type separated laterally, in order to simultaneously drive each of the interruption structures of the blowing type by driving a jet of high pressure gas against the corresponding arc that forms inside each interruption structure of the type of blowing.
