摘要
利用多针电晕增强放电装置,在无气流和存在高速气流的情况下都得到了稳定的大气压辉光.通过纪录发光图片、电流-电压波形和伏安特性曲线的方法对影响放电稳定性的因素做了细致地研究,发现了在从电晕放电到辉光放电的过程中存在着过渡阶段,表现为出现带有直流成分的Trichel脉冲.气流速度、极板间距以及针尖锥度和凹坑曲率半径的匹配程度都对放电的稳定性和电流密度有着重要的影响.
In a multi-pin to multi-sphere plane DC negative corona discharge configuration at atmospheric pressure, stable and diffuse glow discharge has been obtained. The effect of the air flow velocity, the gap distance and the electrode structure on the discharge mode transition and the stabilization of the glow discharge is investigated by means of electric measurements and emission recording. The stahilization mechanism of the glow discharge is discussed. It is found that there is a transition phase characterized by Trichel pulse with DC component between corona and glow discharge.
