Abstract

894,215. High-tension switches. REYROLLE & CO. Ltd., A. Nov. 4, 1960 [Nov. 5, 1959], No. 37638/59. Class 38 (5). In a circuit-breaker assembly comprising one or more interrupters 10 in series with a switch 11 arranged to open after arc extinction by the interrupters 10 and in which the interrupters and switch remain open until the circuitbreaker is required to be closed, an impedance 20 is connected across the switch and has such a value that, with the interrupters 10 and switch 11 open, approximately one-fifth of the system voltage applied across the circuitbreaker assembly will fall across the seriesbreak switch 11. The impedance 20 is preferably a capacitor and voltage-sharing impedances 13 which shunt the interrupters 10 may also be capacitors. The interrupters may be of the air-blast type supported on insulators 12 on a local reservoir 18 or alternatively smalloil volume interrupters may be used. The switch 11 comprises a horizontally rotatable arm 14 on a torque-shaft insulator 15.
