| 摘要 |
<p>The invention relates to the use of a mixture comprising decafluoro-2-methylbutan-3-one and a carrier gas or dilution gas as a medium for electrical insulation and/or for extinction of electric arcs in a medium- or high-voltage electrical device. It also relates to a medium- or high-voltage electrical device in which electrical insulation and/or extinction of electric arcs is/are implemented by a mixture comprising decafluoro-2-methylbutan-3-one and a carrier gas or dilution gas. Applications: electrical transformers, gas-insulated lines for transporting or distributing electricity, set of busbars, electrical connection/disconnection devices (circuit breakers, switches, switch-fuse sets, disconnectors, earthing switches, contactors, etc.).</p> |
