    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. But less attention has been paid to the thermal properties of an SF6/N2 mixture, especially with insulation materials overheating happening simultaneously. In this paper, thermal decomposition properties

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

    The results showed that thermal properties of 20% SF 6 /N 2 (volume fraction of SF 6 is 20%) mixture has faster degradation than 40% SF 6 /N 2 mixture. As ratio of SF 6 content decreases, thermal stability of the system decreases, and the decomposition process of SF 6 is exacerbated. Moreover, a mathematical model was established to determine happening of partial overheating faults on the epoxy resin surface in SF 6 /N 2 mixture.
