  • Analysis of SF6/N2 gas mixture decomposition by-products in

    Two methods have been carried out for the analysis of SF6/N2 gas mixture decomposition by-products in electric discharges: infrared spectroscopy and gas chromatography. The infrared spectroscopy is a rapid method from which we can have qualitative analysis about all the products in a mixture, except those having the same absorption lines.

    SF6 content, a SF6/N2 mixture exhibits many of the desir-able properties of SF6 as a gaseous dielectric. It has been suggested that this mixture may constitute a synergistic com-bination: The buffer gas (N2) serves to cool energetic elec-trons into the low-energy region where the electronegative gas (SF6) captures them with a remarkably high cross-

    Feb 15, 2015 · 1. Introduction. Sulfur hexafluoride (SF 6) has been widely used as an insulating and etching gas in the electric industry due to its chemical stability, non-toxicity, non-combustibility, and good insulating characteristics , ; however, SF 6 is a very potent greenhouse gas since its global warming potential (GWP) is 23,900 times higher than CO 2, and its lifetime is estimated to be 3200 years

  • Effects of vibrationally excited N2 molecules on dielectric

    Figure 12b shows that the attachment reaction rate of the 50% SF 6-50% N 2 mixture is higher than both the 5% SF 6-95% N 2 mixture and the 95% SF 6-5% N 2 mixture. SF 6 holds the higher attachment cross section than N 2 , and therefore the attachment reaction is enhanced when the SF 6 concentration increases from 5% to 50%.
