Abstract (en)
[origin: EP2056322A1] A high-voltage circuit breaker (10) filled with insulating gas, comprises 2 oppositely-arranged arcing contacts (15), surrounded by an insulating nozzle (20); 2 oppositely-arranged main contacts (16), outside of the insulating nozzle, each oppositely-arranged main contact being assigned to one of the arcing contacts; and diverting device (50) to divert an insulating gas flow (27) from a region between the 2 arcing contacts. The diverting device includes mechanism to divert insulating gas from the insulating gas flow that is diverted from the region between the 2 arcing contacts. High-voltage circuit breaker (10) filled with insulating gas, comprises 2 oppositely-arranged arcing contacts (15), surrounded by insulating nozzle (20); 2 oppositely-arranged main contacts (16), outside of the insulating nozzle, each oppositely-arranged main contact being assigned to one of the arcing contacts; and diverting device (50) to divert an insulating gas flow (27) from a region between the 2 arcing contacts. A respective insulating gas flow is conducted outside of the insulating nozzle from both directions in a direction toward the main contacts. The diverting device includes mechanism to divert insulating gas from the insulating gas flow that is diverted from the region between the 2 arcing contacts, such that the 2 insulating gas flows flowing in both directions toward the main contacts have approximately the same effect on the insulating gas flowing in the region of the 2 main contacts, thus preventing the insulating gas present in this region from being displaced.
