Abstract:
1. High-voltage circuit breaker filled with insulating gas, comprising: two oppositely-arranged arcing contacts, surrounded by an insulating nozzle; two oppositely-arranged main contacts, outside of the insulating nozzle, each oppositely-arranged main contact being assigned to one of the arcing contacts; at least one mechanism configured to partition an insulating gas flow from a region between the two arcing contacts into first and second insulating gas flows of opposite directions, wherein the first and second insulating gas flows are conducted outside of the insulating nozzle from opposite directions toward the main contacts; and at least one diverting device configured to reduce the first insulating gas flow by diverting insulating gas from the first insulating gas flow, such that the first and second insulating gas flows flowing from opposite directions toward the main contacts do not displace the insulating gas present in a region around the two main contacts, wherein the least one diverting device is configured to divert insulating gas from the first insulating gas flow, such that the first and second insulating gas flows flowing from opposite directions toward the main contacts have approximately the same value with respect to at least one of volume and amount.
