Abstract (en)
[origin: WO2013037573A1] The invention relates to an on-load tap changer consisting of an energy store, a drive shaft designed as a screw spindle, vacuum switching tubes and a contact carrier and vertically arranged tap contacts. Actuation of the vacuum switching tubes occurs in dependence on the contacts. According to the invention, the vacuum switching tubes are actuated via cam discs and deflection assemblies. In parallel, the contacts attached to the contact carrier are moved vertically by the drive shaft and the tap contacts are thus actuated.
