Abstract: A tap changer with vacuum-switching tubes for controlling a transformer having taps has a selector for power-free selection of a one of the taps to be switched and a load-changeover switch for actual switching over from the connected tap to a new, pre-selected one of the taps. A first cam disk is fixed against rotation on a rotatable switch shaft, and a rocker lever arrangement has a first roller for actuating the vacuum-switching tubes. A second cam disk is also rotationally fixed on the switch shaft, and there are two further arms of U-shaped construction on the rocker lever arrangement. A lever has a free end provided with a second roller that co-operates with the second cam disk. This lever is between the further arms and mounted to be rotatable about an axis. A compression spring is provided between the lever and the further arms.

Abstract: 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.

Abstract: An indexing transmission for an on-load tap changer or a tap selector of a tapped transformer has a rotatable cam disk having an outer edge formed with a succession of convex and concave cam formations in regular succession and merging with one another, a crank transmission driving the cam disk, and a drive output disk acted on by the cam disk and having an outer edge. Engagement rollers rotatable on an end face of the drive output disk near the outer edge of the drive output disk roll on the outer edge of the cam disk. A switch shaft is rotationally fixed to the drive output disk such that the cam disk in cooperation with the engagement rollers of the drive output disk triggers a stepped rotation of the switch shaft through a defined step angle.

Abstract: The invention relates to an energy store for a load tap changer with a longitudinally movable lifting carriage and an also longitudinally movable snap-action carriage which follows the movement of the lifting carriage after being triggered and whose longitudinal movement is converted into a rotary movement of an output shaft that actuates the load tap changer. In order to do so, two rolls which are guided in an especially geometrically designed guide rail are disposed on the snap-action carriage. Only one of the two rolls is positively guided in the guide rail during the first part of each movement of the snap-action carriage while the other roll can be moved freely. The second roll that could previously be moved freely is then positively guided during the second part of the movement while the roll which was previously guided can be moved freely. The roll which was initially guided is positively guided once again during the third part of the movement.
