摘要: The present invention relates to an insulating gas used for electrical insulation or arc extinguishing of an electrical device, and an electrical device for insulating electricity using the same. The insulating gas of the present invention, which may replace SF6 gas, consists of a mixed gas of trifluoromethyl trifluorovinyl ether (CF3OCFCF2) and a carrier gas. The insulating gas of the present invention has the characteristics of a low boiling point, high dielectric strength, low toxicity, and a low global warming potential (GWP=1 or less), and thus may replace SF6, and the low global warming potential with no loss of high insulating capacity and arc extinguishing capability may reduce greenhouse gases.
