在环境空气中的负电晕放电中，可以观察到不同的放电模式。本文确定了这些模式对应的放电电流区域。研究了阳极几何形状、阳极电阻率、极间距离和气体流量对标记电晕到辉光和辉光到火花转变的阈值电流的影响。实验数据的备份由分析处理的电离不稳定性发展内的一个本地电流点上的金属和电阻阳极。
In negative corona discharges in ambient air different discharge modes can be observed. In this paper the discharge current regions corresponding to these modes are determined. The influence of anode geometry, anode resistivity, inter-electrode distance and gas flow on the threshold currents that mark the corona-to-glow and glow-to-spark transitions is investigated. The experimental data are backed up by an analytical treatment of ionization instability development within a local current spot on metallic and resistive anodes.
