Abstract

The invention concerns a high-voltage circuit breaker (10) filled with insulating gas having a main axis A, comprising arcing contacts (12, 16) and an insulating nozzle (22);wherein an insulating gas flowing from a storage chamber and heated by an electric arc (26 between the two arcing contacts (12, 16) is partitioned into a first gas flow (32) and a second gas flow (34) conducted outside of the insulating nozzle (22) from opposite directions toward a main gas chamber (42),wherein the first gas flow (32) flows through a first intermediary gas chamber (36) and the second gas flow (34) flows through a second intermediary gas chamber (50) and is partitioned in a first portion (56) directed to the main gas chamber (42) and a second portion (60) directed to an exhaust gas chamber (62),characterized in that the first portion (56) of the second gas flow (34) is smaller than the second portion (60) of the second gas flow (34).
