USE OF A MIXTURE COMPRISING A HYDROFLUOROOLEFIN AS A MEDIUM-VOLTAGE ARC-EXTINGUISHING AND/OR INSULATING GAS AND MEDIUM-VOLTAGE ELECTRICAL DEVICE COMPRISING SAME

摘要

The invention relates to the use of a mixture comprising a hydrofluoroolefin, possibly associated with a dilution gas, as a gaseous electrical insulation and/or electrical arc extinguishing medium in substation medium-voltage electrical device. It also relates to medium-voltage electrical device in which electrical insulation and/or electrical arc extinguishing is (are) performed by a gaseous medium comprising hydrofluoroolefin, possibly associated with a dilution gas.
