Abstract
619,474. Regulating switches. FOSTER TRANSFORMERS & SWITCHGEAR. Ltd., JENNINGS, R. E., ELLIS, R. F., and BAGNALL, R. I. Dec. 12, 1946, No. 36701. [Class 38 (v)] A tap-changing switch suitable for the transformer disclosed in Specification 607,347, [Group XXXV], comprises an insulating plate a carrying respectively on its upper and lower sides high voltage-difference studs f and low voltage -difference studs c, the latter being connected to the transformer winding through resistance wire, Fig. 8 (not shown). Movable brushes h, h<1>, g of copper or carbon connect the studs f, c with contact rings d, e and b respectively. The brush g is spring-mounted in a holder i secured to an operating spindle k and brushes h, h<1> are mounted in a holder j secured to a gear-wheel l through which the spindle freely passes. A pinion r rotatable on an arm t secured to the spindle k engages the gear l and another gear q having slightly fewer teeth and fixed to the plate a. Rotation of the spindle k causes the brush g to make a number of revolutions for one revolution of the brushes h, h<1>. More than one revolution of the latter is prevented by a cam m on the gear l, or holder j, depressing a spring-loaded stop pin n into engagement with a projection o on the holder i, at the end of travel in either direction. The gear-wheels may alternatively comprise circular racks or contrate-wheels engaged by a pair of bevelled pinions.
