Abstract
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.
Claims15
A process for providing electric insulating and/or electric arc extinguishing within a sealed enclosure of a medium-voltage electrical device, the process comprising:
- enclosing a gaseous medium in the sealed enclosure comprising electrical components,
- wherein the gaseous medium comprises a hydrofluoroolefin comprising three carbon atoms and a fluoroketone comprising five carbon atoms.
A medium-voltage electrical device, comprising:
- a sealed enclosure in which electrical components are located together with a gaseous medium providing electric insulating and/or electric arc extinguishing within the sealed enclosure,
- wherein the gaseous medium comprises a hydrofluoroolefin comprising three carbon atoms and a fluoroketone comprising five carbon atoms.
