Abstract (en)

[origin: US5770828A] The circuit-breaker has a quenching chamber which is filled with an insulating medium, is of cylindrical design and has a quenching zone extending along a longitudinal axis. In addition, it has a fixed contact arrangement, which is arranged in the course of a main current path, and a moving contact arrangement. Furthermore, a blowing volume is provided which stores the increased pressure of the insulating medium which occurs during a disconnection process. At least one contact link, which has two contact points, electrically conductively connects the fixed contact arrangement and the moving contact arrangement to one another in the connected position. The contact link is also mounted to a holder such that it can rotate. The side of the contact link which interacts with the fixed contact arrangement is acted on by a force directed outward in the radial direction with respect to the longitudinal axis.
