摘要

为研究爆炸性环境电感分断放电建弧过程，基于IEC-SSTA（IEC safe spark test apparatus）电弧放电宏观特性，建立极间微观粒子输运模型，研究建弧过程极间粒子数密度和电势的演化规律；分析爆炸性环境对放电起主要贡献的带电粒子类型。仿真结果表明：鞘层和等离子体区的形成标志着电弧的产生；在两种气体环境中对放电起主要贡献的正离子不同，而负离子、消耗电子能量的自由基和激发态粒子相同；甲烷—空气环境下电感分断电弧放电作用更强。

Abstract

For studying the arc building process of the inductor-disconnected discharge (IDD) arc in explosive environment

a micro particle transport model between electrodes is set up on the basis of the macroscopic characteristics of IEC safe spark test apparatus (IEC-SSTA) arc discharge so to study the evolution of particle number density and potential between electrodes during arc building process. The types of charged particles mainly contributing to the discharge in the explosive environment are analyzed. The simulation results show that the formation of sheath and plasma region marks the generation of arc. In the two gas environments

the positive ions that make the main contribution to the discharge are different

while the negative ions

free radicals that consume electron energy and excited particles are the same. The effect of inductive breaking arc discharge is stronger in methane air environment.
