摘要： An on-load tap changer for uninterrupted changeover between winding taps of a tapped transformer has a separate selector for power-free preselection of the winding tap to be switched to, a separate load changeover switch for the actual load changeover from the previous to the preselected new winding tap, a rotatable drive shaft, and a force accumulator with at least one force-accumulator spring that for each load changeover is initially stressed by the drive shaft and after triggering thereof abruptly actuates the load changeover switch. A gear operatively connected with the drive shaft can load the force accumulator. A first mechanical freewheel between the gear and the force accumulator temporarily decouples the force accumulator from rotation with the drive shaft in such a manner that the force accumulator can be stressed with a delay in time after the start of actuation of the drive shaft.

摘要： 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.

摘要： 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.

摘要： A tap changer for uninterrupted switching over between winding taps of a tapped transformer has two load branches each for a respective phase to be switched. Each load branch has a vacuum switching contact acting as main contact and parallel thereto at least one series connection of a switch-over resistance and a respective further vacuum switching contact. The two load branches are connected with a common load shunt or connectable by mechanical switching elements. Two respective vacuum switching contacts of each load branch are constructionally combined to form a single vacuum switching tube with two separate movable contacts actuatable independently of one another and a common fixed contact. The common fixed contact is connected with the common load shunt or connectable mechanical switching contacts.
