摘要

为深入理解电极介质覆盖窄空气隙放电过程的动力学行为

探索不同外施电场条件下带电粒子行为、覆盖介质特性及间隙尺度对气隙放电的影响

建立了一维自洽流体力学的气体放电模型并进行数学分析

获得了大气压下电极介质覆盖窄空气间隙电场、粒子行为和介质表面电荷积聚过程的时空分布

以及与外施电场之间的对应关系.结果显示

外施电压的幅值、频率的变化对放电电流的幅值以及半个周期内的放电脉冲个数都会产生影响.另外

介质层厚度及介电常数的变化对放电电流的幅值及脉冲个数也会产生影响

但影响不大.

Abstract

【Abstract】 With the purpose of deeply understanding kinetic behavior of gas discharge in gas-dielectric insulation

research was carried out for exploring the kinetic behaviors of particles under different external applied electric fields

and revealling the effects of the short air-gap discharge under different dielectric characteristics and gap dimensions.Meanwhile

the one dimensional and self-consistent fluid model of the gas discharge was established and mathematical analysis was also implemented

and the...
