Abstract:
The present invention relates to an electrical insulator (2, 2') for an electrical apparatus, said insulator (2, 2') comprising a body (4, 4') containing an electrical insulating solid material (6) and non-solid inclusions (8) dispersed within the body (4, 4'). According to the invention, at least a portion of the inclusions (8) comprise at least one organofluorine compound having a lower Global Warming Potential than SF 6 .
Abstract:
The present invention relates to a dielectric insulation or arc-extinction fluid comprising or essentially consisting of: a) a fluorinated organic compound FOC1 as a first fluid component A in mixture with b) a second fluid component B different from the said first fluid component A. According to the invention, said first fluid component A is a hydrochlorofluoroolefin.
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.
