Title (EN) GAS-INSULATED MEDIUM OR HIGH VOLTAGE ELECTRICAL APPARATUS INCLUDING CARBON DIOXIDE, OXYGEN AND HEPTAFLUOROISOBUTYRONITRILE
(FR) APPAREIL ÉLECTRIQUE MOYENNE OU HAUTE TENSION À ISOLATION GAZEUSE COMPRENANT DU DIOXYDE DE CARBONE, DE L'OXYGÈNE ET DE L'HEPTAFLUOROISOBUTYRONITRILE
Abstract: front page image
(EN)The present invention relates to a medium or high voltage electrical apparatus including a sealed enclosure in which electrical components and a gaseous mixture are located, which ensure the electrical insulation and/or the extinction of the electrical arcs that likely to occur in said enclosure, the gaseous mixture including heptafluoroisobutyronitrile, carbon dioxide and oxygen in small quantities. Electrical components that are covered with a solid dielectric layer of variable thickness can be located in the sealed enclosure of the electrical apparatus according to the invention.
(FR)La présente invention concerne un appareil électrique moyenne ou haute tension comprenant une enceinte étanche dans laquelle se trouvent des composants électriques et un mélange gazeux assurant l'isolation électrique et/ou l'extinction des arcs électriques susceptibles de se produire dans cette enceinte, le mélange gazeux comprenant de 1 'heptafluoroisobutyronitrile, du dioxyde de carbone et de l'oxygène en faibles quantités. Dans l'enceinte étanche de l'appareil électrique selon l'invention, peuvent se trouver des composants électriques recouverts d'une couche diélectrique solide d'épaisseur variable.
