Abstract

During the research of a complete stage sliding discharge on a surface of solid dielectric in atmospheric air in pulsed mode, an effect of self-organization of the discharge formation was found. With increase of pulse repetition rate, a change of the current flow pathway occurs. From the surface of a dielectric substrate, starting from a middle part of the discharge gap, the discharge channel shifts to surrounding gas volume. We explained this phenomenon by an accumulating ionization effect within gas volume due to the difference of vibrational relaxation time of oxygen, depending on temperature on dielectric substrate and within gas volume above the surface.

脉冲模式下空气中完全级滑动放电形成的自组织电离机制
在研究大气中固体介质表面脉冲模式下的全级滑动放电过程中,发现了放电形成的自组织效应。随着脉冲重复频率的增加,电流流动路径发生变化。从介质衬底表面开始,从放电间隙的中间部分开始,放电通道向周围气体体积移动。我们解释了这一现象,由于氧的振动弛豫时间的差异,气体体积内的累积电离效应,这取决于介电基片上的温度和表面以上气体体积内的温度。
