主权项 1. An on-load tap changer for uninterrupted switching between different winding taps of a tapped transformer, consisting of a selector and a load changeover switch, wherein the selector has fixed selector contacts that are respectively electrically connected with the individual winding taps and that are arranged along a linear path, the fixed selector contacts are selectably connectable by two longitudinally displaceable, movable selector contacts of the selector, wherein switching elements are provided in the load changeover switch for uninterrupted switching for each phase, a motor drive with a drive motor for introduction of switching process of the on-load tap changer is provided, the two movable selector contacts of the selector and the switching means of the load changeover switch are, for the uninterrupted switching, so directly actuatable by the drive motor that the introduction of the drive movement of the drive motor to the movable selector contacts, and the switching means for the uninterrupted switching takes place without interposition of a force-storing unit.
