Abstract
A vacuum switching apparatus is equipped with a switching vessel which can be actuated by a drive unit at ground potential by means of a drive assembly transmitting the drive motion. The drive assembly includes a lever made of insulating material which is fulcrumed about an electrically conductive bearing pin. The lever serves as the actuating member of the switching vessel and the bearing pin is at an intermediate potential between the grounded and the high-voltage-carrying parts. The invention is suited particularly for single-pole or multi-pole vacuum switching apparatus in the medium-voltage range.
