Abstract
An electrical breaker device, in particular a high-voltage circuit breaker, and a method for improved quenching gas cooling are disclosed. Cold gas is stored intermediately in the exhaust region, and a first partial gas flow is guided to bypass the intermediately stored cold gas and to flow off into the breaker chamber, the intermediately stored cold gas being forcibly displaced out of the exhaust region with the aid of a second partial gas flow and being mixed with the first partial gas flow before flowing off into the breaker chamber housing. Exemplary embodiments relate, inter alia, to the design of the intermediate storage volume for the cold gas and to auxiliary means for precooling the hot quenching gas. Advantages are, inter alia, improved quenching gas cooling, an increased circuit breaker rating and/or a more compact breaker design.
