Abstract
980,247. High voltage switches. BROWN, BOVERI & CO. Ltd. Aug. 6, 1963 [Aug. 7, 1962], No. 30913/63. Heading H2B. In a compressed gas circuit breaker having multiple series connected interrupters 3c and isolators 2c, the interrupters are in pairs in twin chambers on insulator columns 3 while the isolators are in chambers supported by a separate insulator column 2 and constantly subjected to the gas pressure in a reservoir 1 through at least one of the insulator columns 3 supporting the interrupters. Upon the application of an electrical pulse at 10a an electromagnet 3l opens a valve 3h to admit compressed gas from the reservoir 1 to the underside of a piston 3f which opens an operating valve (not shown) in the interrupter head through a connecting rod 3d. Simultaneously an electromagnet 8c releases a latch to open a valve 8a passing compressed gas through a line 9 to the operating valve 2h of the isolators at the foot of insulator column 2, thus opening the isolators a short while after the interrupters but before the latter reclose. The circuit breaker is reclosed by venting line 9 through a valve 8d opened by a latch tripped by a further electromagnet 8f. Upon failure of one or other of the electrical connections 10, 10b, the operating sequence is preserved by means of conduits 3r, 3q.
