Abstract
SF6 has been widely used in electric industries due to its good insulation characteristics and arc extinguishing performance, but research on its substitutes has become a hot topic in recent years to reduce serious greenhouse effect caused by SF6. Perfluoroisobutyronitrile (C4F7N) and its mixtures are promising to replace SF6 due to their excellent insulation performance and relative low greenhouse effect. This article studied basic decomposition paths of C4F7N/N2 gas mixtures using density functional theory (DFT), and calculated the main decomposition reaction rate constants with transition state theory (TST). The results can lay a theoretical basis for C4F7N gas insulated electrical equipment insulation evaluation.
