Abstract
1,255,621. Pulse generators. SOUTH WALES SWITCHGEAR Ltd. 29 Nov., 1968 [4 Jan., 1968], No. 558/68. Heading H3P. [Also in Divisions H1 and H2] A capacitor discharge type pulse generator uses " divided switch " arrangement, Fig. 1, comprising a number of switches 8 which are constrained to operate in unison (e.g. by means of an insulating rod 7) and are arranged such that circuit elements connected across them are in a first series connection for one position of the switches and in a second series connection, with at least some of them reversed in polarity, in another position of the switches. The arrangement includes an assembly which comprises a plurality of substantially flat aligned parallel plates 1, 2, 3, 4 each provided with first, second, third and fourth terminals a 1 , b 1 , c 1 , d 1 , a 2 , b 2 , c 2 , d 2 &c. and a switch actuator rod 7 passing through the assembly of plates and carrying a switch arm 8. adjacent each plate for making connection between terminals such as a 1 and c 1 or b 1 and d 1 in the two positions of the switches. Movement of the switches from the positions shown in Fig. 1 to the positions where they interconnect terminals b 1 and d 1 , b 2 and d 2 , b 3 and d 3 , b 4 and d 4 , reverses the polarity of series connected rectifiers 6. The arrangement may be immersed in oil and mounted within a rectifier housing. In another embodiment, Figs. 4 and 5, the "divided switch " is connected such that it reverses the polarity of alternate secondary windings of a transformer so as to reduce the output from a maximum to zero (Fig. 5). Alternatively each transformer winding could be replaced by a number of complete rectifier sets. As another embodiment, the switch may be incorporated in a cascade rectifier generator of the Greinacher type (Figs. 2 and 3, not shown). Alternatively, it may be used in a high impulse voltage generator which comprises a rectifier/capacitor set c 1 (Fig. 6) in series with a further set (c 2 ) of series connected capacitors. One or both of the capacitor sets is interconnected by an arrangement similar to Fig. 1. The capacitor sets having been charged up, an impulse voltage appears across a resistor (R) when the polarity of one set is reversed.
