Definitions
- the present invention relates to a gas used for the electrical insulation or extinguishing of electric arcs, as well as electrical appliances provided with an enclosure containing this gas.
- the electrical insulation and, where appropriate, the extinction of electric arcs are typically provided by a gas that is confined within an enclosure of these devices.
- a gas that is confined within an enclosure of these devices.
- the most commonly used gas is sulfur hexafluoride (SFe): this gas has a relatively high dielectric strength, good thermal conductivity and low dielectric losses. It is chemically inert and non-toxic to humans and animals and, after being dissociated by an electric arc, it recombines quickly and almost completely. In addition, it is nonflammable and its price is still moderate today.
- SFe has the major disadvantage of having a global warming potential (GWP) of 22,800 (relative to CO2 over 100 years) and a residence time in the atmosphere of 3,200 years, which places it among the gases with strong greenhouse effect.
- GWP global warming potential
- Hybrid systems have been proposed which combine gas insulation with solid insulation (EP 1724802). This, however, increases the volume of electrical appliances compared to that allowed by SFe insulation; and the cut in the oil or vacuum requires a redesign of the equipment.
- Perfluorocarbons generally have interesting dielectric strength properties, but their GWP is typically in a range of 5,000 to 10,000.
- SFe and other gases such as nitrogen or nitrogen dioxide are used to limit the impact of SFe on the environment: see, for example, WO 2009/049144. Nevertheless, because of the strong SFe GWP, the GWP of these mixtures remains very high.
- a mixture of SFe and nitrogen in a volume ratio of 10/90 has a dielectric strength in alternating voltage (50 Hz) equal to 59% of that of SFe but its GWP is of the order of 8 000 to 8 650.
- Such mixtures can not therefore be used as a low environmental impact gas.
- the document FR 2955970 proposes the use of fluoroketones in the gaseous state for electrical insulation.
- the fluoroketones can be combined with a carrier gas or dilution gas (for example nitrogen, air, nitrous oxide, carbon dioxide, oxygen, helium, etc.).
- Document FR 2975818 proposes a mixture of octofluorobutan-2-one and carrier gas as isolation medium.
- the document FR 2983341 proposes the use of polyfluorinated oxiranes as electric insulation gas and / or electric arc extinguishing.
- Document FR 2986102 proposes the use of a combination of polyfluorinated oxirane and hydrofluoroolefin as electrical insulation gas.
- the hydrofluoroolefins mentioned are 1, 3,3,3-tetrafluoropropene (HFO-1234ze), 2,3,3,3-tetrafluoropropene (HFO-1234yf) and 1,2,3,3,3-pentafluoropropene (HFO -1225ye).
- WO 2012/160158 proposes the use of a mixture of decafluoro-2-methylbutan-3-one and a carrier gas as an electrical insulating gas.
- the document WO 2013/004796 proposes the use of a gas based on hydrofluoroolefin as an electrical insulation gas.
