Abstract

206,841. Akt.-Ges. Brown, Boveri, et Cie. Nov. 13, 1922, [Convention date]. Regulating switches; high-potential switches. -A step-by-step switch for variably tapping a transformer winding in order to vary the transforming ratio consists of a number of annular contacts a mounted in an insulating sleeve which, in turn, is mounted within a metal cylinder e having dome-shaped ends the lower end serving also as an additional annular contact. The contacts are connected by leads d to the tappings and the whole of the fixed contact structure, which includes a cylindrical insulating casing f, is supported within the oil-filled transformer casing by an insulating tube g. The movable contactmember consists of a pair of contact balls c pressed on to the contact rings by two conical surfaces n pressed towards one another by springs m. The balls are retained by fingers o. The moving contact structure has some free movement, afforded by a pin-and-slot connection, on the rod h which is actuated by rack and pinion mechanism from outside the tank.
