Thermal Decomposition Properties of Epoxy Resin in Sulfr hexafluoride/N2 Mixture

The results showed that thermal properties of 20% Sulfr hexafluoride/N2 (volume fraction of sf 6 is 20%) mixture has faster degradation than 40% insulating gas/N2 mixture. As ratio of gaz sf6 content decreases, thermal stability of the system decreases, and the decomposition process of sf6 gas is exacerbated. Moreover, a mathematical model was established to determine happening of partial overheating faults on the epoxy resin surface in insulating gas/N2 mixture.Get price
