Abstract
Official abstract text for this publication.
The invention relates to the use of a gas as a medium for electrically isolating and/or extinguishing electric arcs, said gas comprising a hexafluorobutene. The invention also relates to an electric device comprising a sealed chamber inside which electric components and said gas are located.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrical insulation and/or extinguishing gas for electric arcs, the gas comprising: from 10 to 100 mol % of trans-1,1,1,4,4,4-hexafluorobut-2-ene; and/or from 25 to 100 mol % of 2,3,3,4,4,4-hexafluorobut-1-ene. 2. The gas of claim 1 , wherein the gas is used in a medium-voltage electrical substation appliance. 3. The gas of claim 1 , further comprising a diluent. 4. The gas of claim 1 , wherein the gas is used in a temperature range, a lower limit of which has a value from −30 to 20° C. 5. The gas of claim 1 , wherein the gas is used in a temperature range, a lower limit of which is greater than or equal to 0° C.
