Abstract

1,089,575. Arcing preventing in switches. BROWN, BOVERI & CO. Ltd. Feb. 28, 1966 [March 2, 1965], No. 8592/66. Heading H2B. A rectifier unit for shunting the contacts of a high-power switch, and wherein a control means then opens the circuit of the rectifier in the halfcycle during which it is non-conducting, comprises a column of disc-shaped semi-conductor rectifier elements (7) respectively separated by heat reservoir discs (8) of the same diameter as the semi-conductor elements but of sufficient thermal capacity to absorb the heat produced by a half-cycle of short-circuit current without a dangerous temperature rise, thus enabling relatively small semi-conductor elements to be used. The semi-conductor elements are of silicon and the heat reservoirs may be of molybdenum or tungsten. The column may be built up of cells each consisting of three discs in the sequence molybdenum silicon, molybdenum, the selected number of cells being readily soldered together for improving contact. Terminal leads may be brought out from the semi-conductor elements for connection to potential control elements or, if thyristors are used, to control apparatus.
