    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.

    Abstract: The circuit breaker includes an auxiliary drive mechanism (3). This mechanism is constructed to reverse the direction of movement of the second arc contact section (2). Reversal takes place during circuit breaking, and occurs when the constricted section (6) is no longer partially blocked by the contact end section (2). The auxiliary drive is an electrodynamic drive. It is alternatively taken from the main drive. The auxiliary drive mechanism includes at least one cam track plate (14). Equations describing the constriction geometry are provided. An independent claim is included for the corresponding method.
