Abstract:
PROBLEM TO BE SOLVED: To provide an electric breaker device (1), especially a high voltage circuit breaker (1), and an improved cooling method of quenching gas. SOLUTION: Cold gas (111) is intermediately stored in exhaust areas (7, 8), and a first partial gas flow (11a) is guided so as to bypass the intermediately stored cold gas (111) and flow into a breaker chamber (2). The intermediately stored cold gas (111) is compulsorily exhausted from the exhaust area (7, 8) by reinforcement of the flow of a second partial gas flow (11b), and mixed to the first partial gas flow (11a) before flowing into a breaker chamber housing (3).

Abstract:
The method involves flowing switching gas from an arc-discharging zone to an exhaust area filled with cold gas (111). The switching gas is split up into two partial gas flows (11a, 11b). A part of the cold gas is immediately stored in the exhaust area, and one partial flow is guided to the cold gas and flowed into a switching chamber (2). The cold gas is displaced from the exhaust area with the help of another partial flow, where the former partial flow and the cold gas are mixed with one another before flowing into a switching chamber housing (3). An independent claim is also included for an electrical switching circuit for an electrical power grid.
