Abstract (en)
[origin: WO2012095156A1] The invention relates to a tap changer with a pre-selector for the uninterrupted switching between various winding taps of a tap transformer. The claimed invention is characterised in that instead of the individual lamellas being hinged by means of separate springs, two contact sheets which are arranged essentially parallel to each other are provided. Said contact sheets are guided parallel in by means of U-shaped sheet metal parts and can be pressed together by leg springs in such a manner that between the sides of the contact sheet metal parts facing inwards, the stationary adjacent preselector contacts of a phase are accomodated.
