| Zusammenfassung: | An on-load tap changer for uninterrupted switching between different winding taps of a tapped transformer has a plurality of fixed selector contacts electrically connected with the individual winding taps, arranged in a line, and actuatable by two longitudinally displaceable movable selector contacts. Two vacuum interrupters serve for the uninterrupted switching of each phase. A motor drive actuates the on-load tap changer. The entire load changeover switch is arranged by a transmission module on the underside of a transformer cover. |
