  • SF6/N2 Mixtures for HV Equipment and Practical Problems

    Abstract. Since SF 6 gas has a high dielectric performance and interrupting capability, it is used widely in the Electric Power Industry. Recently, it is recognized that SF 6 gas is a greenhouse gas and therefore, SF 6 /N 2 gas mixtures are proposed as a replacement of pure SF 6.

  • Problems of the application of N2/SF6 mixtures to gas

    Sep 21, 2001 · In designing a gas‐insulated bus (GIB) using N 2 /SF 6 mixtures, there are many application problems, such as the mixture pressure needed in order to maintain the required dielectric and heat transfer performance. Problems of recycling SF 6 are also essential in applying N 2 /SF 6 mixtures.

  • High SF6/N2 selectivity in a hydrothermally stable zirconium

    Sep 15, 2015 · A hydrothermally stable, zirconium-based metal–organic framework called UiO-66-Zr has been studied for its ability to separate SF 6 from SF 6 /N 2 mixtures. The ideal adsorbed solution theory (IAST)-predicted selectivities based on single-component isotherms and the dynamic breakthrough calculations for mixture conditions demonstrate that UiO-66-Zr can effectively separate SF 6 /N 2 mixtures.

  • Thermal Decomposition Properties of Epoxy Resin in SF6/N2 Mixture

    As a promising alternative for pure SF6, the mixture of SF6/N2 appears to be more economic and environment-friendly on the premise of maintaining similar dielectric properties with pure SF6.
