摘要
给出了赝火花开关所需辉光放电腔的具体要求,对赝火开关辉光放电腔进行了优化设计,并对优化后的放电腔进行了粒子模拟和实验研究。粒子模拟结果表明:此放电腔为辉光放电腔,辉光放电建立时间约18.5 ns;辉光放电时,此放电腔阴极位降占整个电位降的主要部分,且阴极位降区净离子密度为一常数。实验结果显示:此放电腔为辉光放电腔,其工作在Paschen曲线最低点左侧,放电电压随气压的升高而降低;当辉光放电电流为0.14~3.60 mA时,放电模式为正常辉光放电。
Abstract
Detailed demand and optimization design of glow discharge cavity of pseudospark switch are presented. Based on the optimum structure, particle simulation and experimental investigation are given. The particle simulation shows that the designed discharge cavity is a glow discharge cavity and the set up time of glow discharge is approximately 18.5 ns. When glow discharge happens, the cathode voltage drop dominates the primary anode voltage drop. In the cathode voltage drop region, the ion density is larger than the electron density and the net charge density is a constant. The experiment indicates that, the glow discharge cavity works on the left region of Paschen curve; as the gas pressure increases, the discharge voltage drops. When the discharge current is more than 0.14 mA and less than 3.60 mA, the discharge mode is normal glow discharge.
