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 gas-insulated high-voltage switchgear includes a contact arrangement that is enclosed in a housing (10) and has two arc contacts in a coaxial arrangement, namely a tulip contact (20) with a constriction and a contact pin (30), said contacts being movable relative to each other along an axis (A). The switchgear also includes two insulating nozzles (40, 50) which are held at a distance to each other in the axial direction. The first (40) of the two insulating nozzles has a first flow channel (41), which is led along the axis and which comprises a first constriction (42), and the second (50) has a second flow channel (51), which is led along the axis and which has a second constriction (52). In the switchgear, the tulip contact (20) is arranged in a first flow channel (41) outflow section (43) which is arranged downstream of the first constriction (42). The sum of the flow cross-sections (Ακ, ΑΣ) of the constriction of the tulip contact (20) and of a third constriction arranged in the outflow section (43) is greater than the flow cross-section (An) of the first constriction (42), wherein a first sub-flow (L11) of a quenching gas flow (L1) can be conducted through the constriction of the tulip contact (20), and a second sub-flow (L12) which is oriented parallel to the first sub-flow (L11) can be conducted through the third constriction. In this manner, the dielectric restoration of an isolating gap which can be found in the arc zone (L) is improved upstream of the tulip contact (20), and the breaking capacity and the operating reliability of the switchgear are thus increased.

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.
