Title:
INSULATING GAS USED FOR ELECTRICAL INSULATION OR ARC EXTINGUISHING BY REPLACING SF6 GAS AND ELECTRICAL DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/086308
Kind Code:
A1
Abstract:
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 same. The insulating gas of the present invention, which can 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 can replace SF6. In addition, since the global warming potential is low while maintaining high insulating capacity and arc extinguishing capability, greenhouse gases can be reduced.
