    摘要: 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.

    摘要: The present invention relates to a load transfer switch for a tap changer, comprising permanent main contacts that switch powerlessly for each phase. The general inventive concept lies in connecting the fixed permanent main contacts of side A or B of the load transfer switch by means of a movable rail-shaped permanent main contact that establishes an electrical connection to the corresponding permanent main contacts of the load line only in the end positions of the movable rail-shaped permanent main contact and in addition only provides for a single deflection for actuation, which connects in a purely compressive manner the plurality of contact fins of the corresponding fixed permanent main contact, which contact fins are connected in a resilient, articulated manner.

    摘要: The invention relates to a load transfer switch for a tap changer for switching among various winding taps of a step transformer without interruption. The general inventive concept lies in fastening both the force accumulator and the load transfer switch not on the bearing plate but rather on the force accumulator support by providing additional receptacles on the force accumulator support, which receptacles are supported over a large area on the oil tank, in particular on the upper permanent main contact supports fastened to the oil tank, of each phase of the load transfer switch in such a way that the force accumulator support is fixed both in the horizontal direction and the vertical direction and thus mechanically unburdens the bearing plate.
