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.

摘要： The invention relates to an on-load tap changer for step transformers, which has one main current branch and one auxiliary current branch for each of the two winding taps to be switched. In each main current branch and auxiliary current branch, switching is accomplished by means of a vacuum switching tube. According to the invention, an additional mechanical contact is provided in each of the main current branches and in each of the auxiliary current branches between the respective winding tap to which said branch is electrically connected and the respective vacuum switching tube in said branch. Said mechanical contacts are switched in such a way that the vacuum switching tubes in the main current branch and the auxiliary current branch of the unconnected winding tap can be galvanically isolated from the unconnected winding tap.
