The variation of C4F7N, C5F10O, and their decomposition components in breakdown under different pressures
Abstract
The decomposition characteristics of C4F7N and C5F10O are basic to understand their insulating and arc-quenching performance, and the decomposition products are related to the equipment discharge fault and insulation state. A chemical kinetic model is employed to study the variation of C4F7N, C5F10O, and their decomposition components under different pressures. The results show that the molar fraction and recombination rate of C5F10O are higher than those of C4F7N, and high pressure has larger influence on the molar fraction and recovery rate of C5F10O than those of C4F7N, so C5F10O presents a better molecular recovery characteristic and dielectric strength than C4F7N at high pressures.
