    Abstract: The invention relates to an electrical switchgear (1), especially a generator switch (1), and a method for improved switching gas cooling. According to the invention, gas jets (12) are formed by a nozzle body (10) in the exhaust region (7), said gas jets are directed towards a deflector (14, 140), and are then subjected to turbulence. Said deflector forms part of the switching chamber housing (3) and has a high heat capacity and/or heat conductivity, such that the switching gas is cooled in a highly efficient manner by turbulent convection of the switching gas turbulence (13) on the deflector (14, 140). Forms of embodiment include the shape of the deflector (14, 140) and the nozzle body (10). The invention is advantageous, inter alia, in that the switching chamber housing (3) is protected from hot gases, the cooling of the switching gas is improved, and the switching capacity is increased.

    Abstract: An electrical switching device (1) is filled with a dielectric insulating medium comprising an organofluorine compound, in particular a fluoroether, a fluoroamine, a fluoroketone or a fluoroolefin, and comprises at least an arcing contact arrangement with a first arcing contact (4a) and a mating second arcing contact (4b). At least a first intermediate volume(7) is provided downstream from the first arcing contact (4a), and/or at least a second intermediate volume (8) is provided downstream from the second arcing contact (4b). The intermediate volumes (7, 8) are for intermediate pressure enhancement and exhaust gas jet formation for turbulent convective heat transfer to metal walls (7b, 8b) of the exhaust system.In embodiments, the first and/or second intermediate volume (7, 8) is delimited by at least one moveable wall (14a, 14b)arranged transversally to the longitudinal axis (z) and shiftable parallel to it by an actuation device(15, 16, 17).

    Abstract: The switch is used for interruption of large currents and contains a housing (10) filled with insulating gas, a contact arrangement which is arranged in the housing (10) and has two switching pieces (20, 30), which can move relative to one another along an axis (A) and each have a rated current contact (22, 32) and an arcing contact (21, 31) as well as containing a drive (D), which acts on a first (10) of the two switching pieces. The switch furthermore contains an apparatus (M), which is used for detection and indication of the contact wear, caused by the arc effect, of the two arcing contacts (21, 31), and has an indication (70) arranged outside the housing (10). In the case of this switch the remaining life, which is governed by the contact wear of the arcing contacts (21, 31), is detected and indicated by simple mechanical means. This is achieved, when the contact arrangement is closed, by the two arcing contacts (21, 31) abuting against one another head-to-head at a respective free end, forming an abutment point (S), by the arcing contact (31) of the second switching piece (30) being mounted such that it can be moved axially against the influence of a preloaded spring (33) and being fitted with an axially aligned operating member (50) at the end thereof averted from the abutment point (S), and by the detection and indication apparatus (M) having a transmission (60), which is passed in a gas-tight manner through the housing (10) and has a drive element (63) which is coupled to the operating member (50).

    Abstract: Disclosed is a heavy-duty circuit breaker featuring arc blow-out. Said circuit breaker comprises a hot gas-sensitive and/or gas pressure-sensitive element (10) that is protected from a hot gas flow (8) by means of a seal (1). Advantageously, said seal (1) is embodied as a movable contactless seal (1). The seal (1) is preferably provided with a means (2a) for generating a partial hot gas flow (8a) of the hot gas flow (3), a means (2) for reducing the mass flow rate of the partial hot gas flow (8a), and a means (3) for expanding the volume of the partial hot gas flow (8a). The mass flow reducing means (2) is advantageously configured as a duct (2) while the expanding means (3) is advantageously embodied as a pressure relief chamber (3). The element (10) can be a guiding element, a contacting element, or a sealing element, for example.
