  • Patent number: 4877928
    Abstract: A release mechanism for a high speed circuit breaker comprises a roller rotatably supported on an axle in a mobile contact bridge. A jack is acting in the circuit closing direction on the roller, and the frontal side of the jack is in the form of a slide. The force of a disconnecting spring acts on the contact bridge in a disconnecting direction. The release mechanism to be provided with the connected contact bridge is capable of very rapid release, so that high short circuit currents may be interrupted very rapidly. This is obtained by the slide having a configuration such that in the connected state of the contact bridge the frictional forces acting on the roller are compensated.
