Abstract (en)
[origin: WO2019233914A1] The invention relates to a gas-insulated switchgear (1) comprising a housing (2), which has an insulation chamber (6), and comprising current-conducting components (3, 4, 16) arranged therein and a gaseous insulation medium (8), which is electrically insulating and/or is used to extinguish an electric arc (10), present in the insulation chamber (6), the insulation medium (8) comprising a fluoronitrile and an oxidising carrier gas. The invention is characterised in that regions (22) which are doped with non-metallic foreign atoms are provided at least beneath parts of the surface (12) of the current-conducting components (3, 4, 16).
