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 19):
The method of performing a current breaking operation by the gas-insulated low- or medium-voltage switch according to  claim 10 , wherein the current is a rated current within a range of up to 2000 A through said switch, and wherein the system voltage is at most 52 kV, the method including:\n separating the first and second contacts from each other by relative movement away from each other along the axis of the switch, so that an arc is formed in the quenching region between the first and second contacts; and blowing, by the arc-extinguishing system, a subsonic swirl flow of a quenching gas onto the quenching region.
