MIXTURE OF HYDROFLUOROOLEFIN AND FLUOROKETONE FOR USE AS AN INSULATION AND/OR ARC-EXTINGUISHING MEDIUM AND A GAS INSULATED MEDIUM-VOLTAGE ELECTRICAL DEVICE COMPRISING SAME

摘要

The invention relates to the use of a mixture comprising a hydrofluoroolefin and a fluoroketone, optionally associated with a dilution gas, as an electric insulating and/or electric arc extinguishing medium in a medium-voltage electrical device. It also relates to a medium-voltage electrical device in which electrical insulation and/or electric arc extinguishing is (are) provided by a mixture comprising a hydrofluoroolefin and a fluoroketone, optionally associated with a dilution gas.
