Abstract

Det er beskrevet et høyspenningsanlegg med et iso- lergassfylt metallisk hus (1,5) som omgir spen- ningsførende aktivdeler (3, 7). Det er forsynt med isolatorer for elektrisk isolerende avstivning av aktivdelene (3, 7) i huset (1,5), med elektrisk isolerende drivinnretninger for betjening av de bevegelige partier i aktivdelene og med minst ett beskyttelsesbelegg (11) som tildekker i det minste isolatorene og de elektrisk isolerende drivinnret- ninger. Det skal tilveiebringes et høyspenningsanlegg med et beskyttelsessjikt som er ugjennomtrengelig for frigjorte, kjemisk aggresive spaltningsprodukter, spesielt fluss-syre, under anleggets hele levetid. Dette oppnås ved at beskyttelsesbelegget (11) er utformet slik at de ved drift av anlegget, i iso- lergassen dannede spaltningsprodukter trenger inn i beskyttelsesbelegget (11), og at beskyttelsesbe- legget (11) oppviser minst en komponent som reage- rer med spaltningsproduktene under dannelse av minst ett fast, ikke-hygroskopisk omsetnings- produkt. Omsetningsproduktet som dannes ved omset- ningen, forblir derefter i beskyttelsesbelegget (11).A high voltage system is described with an insulating gas-filled metallic housing (1,5) which surrounds live active parts (3, 7). Insulators are provided for electrically insulating stiffening of the active parts (3, 7) of the housing (1,5), with electrically insulating drive means for operating the movable parts of the active parts and with at least one protective coating (11) covering at least the insulators and the electrically insulating drive devices. A high-voltage plant with a protective layer shall be provided which is impervious to released, chemically aggressive decomposition products, especially hydrofluoric acid, throughout the life of the plant. This is achieved in that the protective coating (11) is designed so that the decomposition products formed in the insulating gas, during operation of the plant, penetrate into the protective coating (11) and that the protective coating (11) has at least one component that reacts with the decomposition products. to form at least one solid, non-hygroscopic reaction product. The reaction product formed during the reaction then remains in the protective coating (11).
