Abstract
A metal-encapsulated, gas-insulated high-voltage circuit-breaker includes a fixed contact configuration which is accommodated in its own fixed contact housing, and a moving contact piece configuration which is driven by a first drive and is accommodated in a contact housing that is connected to the moving contact piece configuration or can move with said contact piece configuration during a switching operation. The contact configurations may have contact pieces for a rated current and for guiding and extinguishing an arc. At the same time, a device is provided for producing a gas flow. The device includes a dielectric nozzle in which the arc burns and is blown and which is guided in a sealed manner in the fixed contact housing throughout an entire switching operation. In order to achieve a disconnecter switch function, a second drive is provided which, during or after completion of the disconnection operation, drives the fixed contact housing with the fixed contact piece configuration counter to the disconnection direction of the moving contact piece configuration, in such a way that the insulating nozzle is released from its guide and an isolating path is thus achieved in order to provide a disconnecter switch function.
