SF6放电等离子体分解特性的研究
Research of the Decomposition Characteristics of SF6 Discharge Plasma
摘要
Abstract
The decomposition of SF6 discharge involves complex physical and chemical processes,and arc energy is one of the most important factors.This paper considers the role of arc energy on the plasma temperature,Saha (ionization) equation and Guldberg-Wagge (dissociation) equation is modified to establish mathematical model of SF6 decomposition,SF6 decomposition products and components in calculation,dynamic process of each particle composition and content with temperature changes;Particle number density of each components are calculated in plasma when pressure is 0.1～0.6 MPa and temperature is 300～41 300 K.The spectrum experiment platform is built,and the electron density of arc plasma at pressure of 0.1～0.4 MPa is obtained.The results show that when the temperature of electron is less than 1 000 K,gas begins to decompose.The chemical reaction at different temperatures is not the same.The theoretical calculation results of the electron number density are in agreement with the experimental results,which prove the feasibility and accuracy of the method.关键词
