Abstract

845,390. Regulating switches. SMIT & CO.'S TRANSFORMATORENFABRIEK N.V., W. July 22, 1958 [July 22, 1957], No. 23570/58. Class 38 (5). [Also in Group XXXV] In a polyphase transformer tap-changing switch, corresponding fixed contacts are all arranged in pairs in one and the same circle on the inner surface of a cylinder, for co-operation with movable bridging contacts 52, 52a. The fixed contact pairs 51, 51a are shrouded by insulators 63, 63a and co-operate with contact tips 60, 60a of the movable contacts. The tips project through the walls of insulating cylinders 57 and are carried by bridge members 59, the cylinders each having a toothed wheel 61 cooperating with a toothed rim 62 on the cylinder so that the contact tips move in an epicycloidal manner. There are three contacts 52 carried by a plate 53 secured to a shaft 54, and three contacts 52a carried by a plate 53a secured to a sleeve 55 free on the shaft 54, each plate being moved stepwise so that contacts 52, 52a engage alternate pairs of fixed contacts.
