Abstract

203,555. Coates, W. A., and Metropolitan-Vickers Electrical Co., Ltd. Oct. 7, 1922. High-potential switches; switch boards.- Switch gear to control the connections between duplicate bus-bars 1, 2 or between different sections of bus-bars comprises for each pair of busbars to be inter-connected a single main circuitbreaker 4 for controlling the connection of the bus-bars and of the reactance 3 therebetween, an isolating switch 5 disposed between one terminal of the circuit-breaker and one of the busbar sections thereof, a pair of reactance isolating switches 6, 7 and a direct connection switch 8 disposed between the other bus-bar and the other terminal of the circuit-breaker. The switches 5 - - 8 are of the coaxial contact kind described in Specifications 187,027 and 187,565 and are provided with interlocking arrangements as described in Specification 186,733 whereby the reactance isolating switches and the direct connection switch cannot be operated unless the circuit-breaker is in the open position, the direct connection switch can only be closed when the two reactance isolating switches are open, and the reactance isolating switches cannot be closed until the direct connection switch is open.
