Abstract:
An on-load tap changer uninterruptedly switches between winding taps of a tap-changing transformer. The on-load tap changer includes: at least one selector configured to preselect, in a powerless manner, a selected winding tap of the winding taps; at least one diverter switch configured to actually switch loads from a previous winding tap to a preselected winding tap of the winding taps; at least one toothed gearing comprising a first gearwheel and a second gearwheel, the first gearwheel being assigned to the selector, and the second gearwheel being assigned to the diverter switch; and a drive shaft, which is configured to be actuated by a motor drive. The first gearwheel and the second gearwheel are directly interconnected mechanically in such a way that the first gearwheel and the second gearwheel are simultaneously actuatable. The drive shaft is configured to drive either the first gearwheel or the second gearwheel.
