Abstract
1,176,335. Switchgear arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 13 Dec., 1967 [13 Dec., 1966], No. 55818/66. Heading H1N. In a switchgear arrangement having two sections each section including a main circuit breaker unit 2, 2a connectible through an isolating switch 13, 13a to a bus-bar 7, 7a the two busbars lie parallel and in a plane between and spaced from the two circuit breaker units. The circuit breakers, isolating switches and busbars are contained in individual metal chambers which may be filled with sulphur hexafluoride. The metal chambers are contained in a cubicle divided by walls 10a, 10b as shown. The circuit breakers may comprise series connected vacuum switches a, b, c and are connected by further isolating switches 5 to cables 8. Earthing switches 5a, 6a are associated with each of the isolating switches.
