Abstract (en)
[origin: WO2010012329A1] The invention relates to a manual drive for a tap changer for a tap-changing transformer having a locking unit. The locking unit has a catch which can pivot and has different locking means; the catch can be operated from the outside before an intended switching operation. The locking unit offers as high a degree as possible of safety against inadvertent or else deliberate incorrect operations of the manual drive.
