Abstract:
A gas-insulated low- or medium-voltage switch for system voltages within 1 to 52 kV and for up to 2000 A rated current includes first and second contacts being movable in relation to each other along an axis of the switch and defining a quenching region in which an arc is formed during a current breaking operation; and an arc-extinguishing system for extinguishing the arc during the current breaking operation. The arc-extinguishing system may include a pressurization system with a puffer chamber, and a nozzle system connecting the pressurization system with the quenching region, the nozzle system having a nozzle at its outlet for blowing the pressurized quenching gas onto the arc formed in the quenching region during the current breaking operation; and a swirling device configured for generating a subsonic swirl flow of a quenching gas onto the quenching region during the current breaking operation, wherein the swirling device is arranged at an entrance of the nozzle system. The arc-extinguishing system further includes a swirling device configured for generating a subsonic swirl flow of a quenching gas onto the quenching region during the current breaking operation, wherein the swirling device is arranged at an entrance of the nozzle system.

Claim (Index 4):
The gas-insulated low- or medium-voltage switch according to  claims 2 , wherein at least one of the swirling device and at least a portion of the nozzle system, such as a nozzle at an outlet of the nozzle system, extends along a center axis of the switch.
