Abstract:
A high-voltage power breaker, comprising: first and second mutually opposite switching contacts when connected, are surrounded by an insulating material nozzle coaxially with respect to which a shielding electrode is arranged,the second switching contact performing a movement in the opposite direction to the first switching contact, which can be driven, during operation of the first switching contact, and the shielding electrode controllable based on coupling by a linkage to the second switching contact, in the movement direction of the first switching contact at a speed whose magnitude is less than the speed of the first switching contact, wherein the insulating material nozzle is connected to two tie rods which are diametrically opposite one another with respect to the center axis of the switch, and extend parallel to the second switching contact and are firmly connected on the side facing away from the insulating material nozzle to a first holder, the first holder is arranged such that it can move axially and on which two connecting rods are arranged such that they can pivot, each of which is connected in an articulated manner to one limb of a fork, the fork is guided such that it can rotate in a fixed bearing and has a lever on its side essentially opposite the limbs, to which lever a coupling lever is connected such that it can pivot and is connected to the contact rod which is fit to the second switching contact and can move axially.
