Abstract

1,068,706. Transformers. E. SCHEUBECK. July 27, 1965 [July 28, 1964], No. 31988/65. Heading H1T. Apparatus for load change-over switches for tap switches in variable transformers T comprises main switching sections 11 and 14 each having a plurality of series-connected switches 21, 31, 41, 51 . . . and 24, 34, 44, 54 . . . respectively, and auxiliary switching sections 12, 13 each having a switch-over resistance 32, 33 and a switch 22, 23, said resistances 32, 33 each being divided by tappings into equal parts with equal resistance values corresponding to the number of switches 21, 31 . . . and 24, 34 . . . respectively, said tappings being electrically connected to the connecting leads of the switches 21, 31 . . . and 24, 34 . . . Initially, switches 21, 31 . . . are closed, all other switches being open, and to change over from tap A to tap B, switch 22 is closed and switches 21, 31 . . . opened, switch 23 is then closed, switch 22 is next opened, then switches 24, 34 . . . are closed, and finally switch 23 is opened.
