    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 invention relates to a heavy-duty circuit breaker which can be filled with a quenching gas and which contains a first displaceable arcing contact piece (1), a second displaceable arcing contact piece (2), a drive for driving the first arc contact piece (1) and an auxiliary drive (3) for driving the second arc contact piece (2). A light arc (4) is, optionally, present between the arc contact pieces. The heavy-duty circuit breaker comprises a heating chamber (11) for temporally storing quenching gas which is heated by the arc (4), and an insulating nozzle (5), which is constricted on the cross-section (6) in order to guide a quenching gas flow, which is connected to the heating chamber (11) by means of a channel (7). The constriction of the cross-section (6) is at least partially closed by a damn by one of the two arc contact pieces (2) which may also be displayed as a damn contact piece. The auxiliary drive (3) is embodied in such a manner that during a switching off step the direction of displacement of the second arc contact pieces (2) are reversed from a counter direction to the same direction of the two arc contact pieces (1, 2), when the constriction of the cross-section (6) is no longer at least partially closed by the damn contact piece (2). Advantageously, the mechanism is a mechanism (3) which is driven by the driven.

    Abstract: The compressed-gas cutout (10) according to the invention comprises a first contact (14) and a second contact (18), which are displaceable relative to each other along a longitudinal axis (A). A blow volume (54, 52, 68) is provided around the first contact (14). Said blow volume (54, 52, 68) is connected via a gas channel (44) to an electric arc zone (40) in order to blow at an electric arc produced when disconnecting the first contact (14) from the second contact (18). The blow volume (54, 52, 68) is delimited radially on the outside by a disconnecting element (30), which disconnects the blow volume (54, 52, 68) from a low-pressure chamber (72). In the radial direction, a flow opening (64, 66, 68) enabling gas exchange leads from the low-pressure chamber (72) into the blow volume (54, 52, 68).

    Abstract: Disclosed is an arcing chamber for a heavy-duty circuit breaker that can be filled with a quenching gas. Said arcing chamber comprises a first (1) and a second arcing contact piece (2), at least one (1; 2) of which can be moved by means of a driving mechanism. An arc (4) optionally burns between the contact pieces (1, 2) while a heating chamber (11) is used for temporarily storing quenching gas heated by the arc (4). An insulating nozzle (5) is provided with a throat (6) that is used for directing a quenching gas flow and is connected to the heating chamber (11). A maximum speed v 12,max of the two arcing contact pieces (1, 2) relative to one another, which is at least 1.3 times the relative speed V 12,c of the two arcing contact pieces (1, 2) required for capacitive switching, is reached during a switching-off process. The following particularly applies for the maximum relative speed v 12,max in case a single-chamber heavy-duty circuit breaker is used: v 12,max = 23 x U N p f / (E krit p 0 ), wherein U N represents the nominal voltage of the heavy-duty circuit breaker when the same is embodied as a single-chamber heavy-duty circuit breaker, p represents the first-pole-to-clear factor of the heavy-duty circuit breaker, E krit represents the utilized field strength for discharging the quenching gas, p 0 represents the filling pressure of the quenching gas, and f represents the system frequency for which the arcing chamber is designed.

    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.
