Abstract

604,632. Regulating transformers. FOWLER, J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 29, 1945, No. 32268. [Class 38 (ii)] [Also in Group XXXVII] In a drum-type polyphase tap-changing selectorswitch, the fixed contacts 2 : 7 for each phase are arranged in a zone around the cylinder 1, and selectively engaged by leading and trailing contacts 8 : 13 moved alternately step-by-step, by concentric operating shafts 14, 18, driven through Geneva wheels 25, 26 by a common driver 27. The contact arms 8, 10, 12 are fixed to the tube 14 and the arms 9, 11, 13 pivoted on the tube, and operated from the shaft 18 by keys 20 passing through slots 16 in the tube, Fig. 4. In an arrangement for one phase of a tap-changing circuit; Fig. 5, a switch 37 and divertor resistances 33, 34 are used to change circuit so that the arms 8, 9 of the selector-switch are out of circuit when moving.
