  • Patent number: 10825576
    Abstract: The present invention relates to an apparatus for the generation, the distribution and/or the usage of electrical energy. The apparatus comprises a housing enclosing an insulating space and an electrically conductive part arranged in the insulating space, said insulating space containing a dielectric insulation medium, at least a portion of which being in the form of an insulation gas comprising an organofluorine compound. According to the invention, at least some of the components of the apparatus that are directly exposed to the insulation gas are made of a material which remains unaltered during exposure to the insulation gas for a period of more than 1 year at operational conditions and/or have a surface, at least a portion of which is devoid of any nucleophilic group reactive towards the organofluorine compound and/or reactive towards any degradation product thereof at operational conditions.

  • Patent number: 10818407
    Abstract: The present invention relates to an electrical apparatus having an insulating space which contains a dielectric insulation fluid comprising an organofluorine compound. At least one solid component of the apparatus that is directly exposed to the insulation fluid contains a basic body made of a first material and a protective layer made of a second material different from the first material, the protective layer being directly or indirectly applied on the basic body and having a thickness of at least 50 ?m. The organofluorine compound is selected from the group consisting of: fluoroethers, fluoroketones, fluoroolefins, fluoronitriles, and mixtures thereof, and the first material comprises or consists of a material selected from the group consisting of: a polymeric material, a ceramic, a composite material, and mixtures or combinations thereof.

  • Patent number: 10505349
    Abstract: A device or component thereof is provided for generation, transmission, distribution and/or use of electrical energy. In at least one insulation space formed within the device, there is a current-conducting component. The insulation space includes a dielectric insulation medium that surrounds the current-conducting component. This insulation medium includes a) at least one organofluorine compound selected from the group consisting of fluoroketones, fluoronitriles, and mixtures thereof and b) a carrier gas comprising at least one component selected from the group consisting of air, an air component, CO2, or a mixture of these components. The device includes at least one gas seal for sealing of the at least one insulation space from a further space. The gas seal includes butyl rubber as seal material.
