Abstract (en)
A circuit breaker which includes at least one quenching chamber is described. The quenching chamber is configured to be filled with insulating gas, extends along a longitudinal axis and includes an arcing zone and an exhaust zone. The exhaust zone is configured to dissipate hot insulating gases from the arcing zone into an exhaust tank. At least one deflection volume is enclosed by a deflection housing and is arranged within an inner volume of the exhaust zone. The at least one deflection volume is configured to fluidly connect the arcing zone with the exhaust tank through a plurality of openings within the deflection housing.
