摘要： A circuit breaker includes: first and second contacts moveable relative to each other along an axis of the circuit breaker between an open and closed configuration and defining an arcing region in which an arc is formed during current breaking operation; a nozzle directing a flow of quenching gas onto the arcing region during current breaking operation, a diffusor downstream of the nozzle for further transporting the quenching gas within the arcing region and/or downstream of the arcing region, and a mechanical swirling device arranged downstream of the nozzle and at least partially in the diffusor for imparting a swirl onto the quenching gas flowing along the diffusor, the mechanical swirling device having an axial overlap with the second contact in the open configuration of the circuit breaker.

摘要： The present invention relates to a device for interrupting non-short circuit currents only, and in particular relates to a disconnector, more particularly high voltage disconnector, or to an earthing switch, more particularly make-proof earthing switch, and further relates to a low voltage circuit breaker. The device comprises at least two contacts movable in relation to each other between a closed state and an open state and defining an arcing region, in which an arc is generated during a current interrupting operation and in which an arc-quenching medium comprising an organofluorine compound is present. According to the application, a counter-arcing component is allocated to the arcing region, the counter-arcing component being designed for counteracting the generation of an arc and/or being designed for supporting the extinction of an arc.

摘要： A gas-insulated high-voltage switching device which includes an arcing contact arrangement having a first arcing zone member and a second arcing zone member that are movable relative to one another along an axis. An auxiliary nozzle surrounds at least a part of a second arcing contact unit and has an auxiliary nozzle throat having an axial extension and allowing passage at least of an end of the first arcing contact unit. A main nozzle throat has an axial extension sideways of the auxiliary nozzle throat and allows passage at least of the end of the first arcing contact unit. A cross-sectional area of the main nozzle throat is substantially decreasing in the direction away from the auxiliary nozzle throat so as to form a substantially converging duct for the flow of an arc-extinguishing gas.
