Abstract

The invention relates to a distribution transformer having a tap-changing device for no-break switching between different winding taps of a distribution transformer. The general inventive concept consists in actuating both the selector contact unit and the switching means for no-break load switching by means of a common motor drive without interposition of an energy store.
