Switching system

摘要

A switching system has two contact points and a contact link disposed so at be rotatably movable about an axis of rotation of the contact link between the two contact points. The switching system further has at least one quenching chamber and a magnetic element for producing a magnetic field being parallel to the axis of rotation of the contact link, for driving an arc produced when the contact points are open into the quenching chamber.

1. A switching system, comprising:
two contact rails each having a rail contact point; a contact link having two link contact points and disposed rotatably movable about an axis of rotation of said contact link, when said contact link is rotated to a contact position, each of said link contact points is in direct contact with one of said rail contact points defining a closed contact; at least one quenching chamber; a magnetic element for producing a permanent magnetic field, the permanent magnetic field being parallel to said axis of rotation of said contact link, for deflecting an arc into said quenching chamber and produced when said link contact points are no longer directly contacting said rail contact points; a rotary link mount; a bearing part connected to said contact link in at least one of a radially movable fashion by means of said rotary link mount or in a rotationally movable fashion relative to said bearing part, said bearing part having tangentially running cutouts formed therein; at least one spring, said contact link being coupled to said bearing part by means of said at least one spring biased with said closed contact; and said rotary link mount having bearing elements resting in said tangentially running cutouts, said bearing elements receiving said spring on a spring-end side.
