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: 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.

Abstract: The present invention relates to an apparatus for the generation, the distribution or the usage of electrical energy, said apparatus comprising a housing enclosing an insulating space and an electrical component arranged in the insulating space. The insulating space contains a dielectric insulation gas comprising an organofluorine compound A. The apparatus further comprises a molecular sieve arranged such as to come into contact with the insulation gas. The molecular sieve has an average pore size y greater than the molecular size of at least one decomposition product of the organofluorine compound A generated during operation of the apparatus. The adsorption capability of the molecular sieve for organofluorine compound A is lower than for the at least one decomposition product. According to the invention, the apparatus further comprises at least one desiccant arranged such as to come into contact with the insulation gas.

Abstract: A method and device for operating a fluid-insulated electrical apparatus (1) are disclosed. The insulation fluid (10) of the electrical apparatus (1) comprises at least two fluid components (A,B) which are a priori ingredients of the insulation fluid (10). The method comprises the step of carrying out at least one optical measurement and/or at least one gas chromatographic measurement on the insulation fluid (10). Using this measurement or these measurements or at least one additional measurement on the insulation fluid(10), a first concentration (cA) of the first fluid component (A) and a second concentration (c
B ) of the second fluid component (B) are derived. Then, using the first concentration (c
A ) and the second concentration (c
B ), and, advantageously, a dielectric breakdown strength E
bd of the insulation fluid (10), an operating state (O) of the electrical apparatus (1) is derived.
