Abstract

In a high-voltage power breaker having two mutually opposite switching contacts which, when connected are surrounded by an insulating material nozzle, coaxially with respect to which a shielding electrode is arranged, with a first switching contact, which can be driven, being connected via the insulating material nozzle and a linkage to the second switching contact, such that said switching contact carries out a movement in the opposite direction to the first switching contact during operation of the latter, the shielding electrode is operatively connected to the second switching contact such that, during disconnection, it carries out a movement which controls the electric field in the switching gap.
