Abstract
Aiming at the calculation of the critical breakdown field strength of high-temperature gas mixtures, the zero-dimensional model adopted in this paper is introduced at first. Based on the zero-dimensional model, the critical breakdown field strength of gas mixtures with different components, including the pure gas, the mixture of air & PA6 vapor and the air & POM vapor are calculated. The results are analyzed theoretically. The main contents include the acquisition of particle composition under high temperature, the approximate solution of Boltzmann equation, the calculation of electron energy distribution function (EEDF), the selection of collision cross section data and the calculation of ionization coefficient and adsorption coefficient. The emphasis is on the approximate solution of the Boltzmann transport equation and the analysis of the effect of different gas media on the critical breakdown field strength.关键词
