Gaoya dianqi, 2006 研究了平板-平板电极、多针-平板电极和筛网电极3种电极结构DBD的放电特性,通过测量电压-电流波形图及放电发光图比较了它们的区别,并从放电机理角度对实验结果作了解释。结果表明:平板-平板电极DBD表现为稳定的细丝状放电。而多针-平板电极DBD融合针尖的电晕效应,使得放电空间中呈现扩散圆锥形放电。筛网电极DBD可以实现大气压辉光放电（APGD）,放电更加均匀,放电空间内看不到放电细丝的存在。

Dianci bileiqi, 1986 本文介绍了对各类型悬式绝缘子在交流电压下的无线电干扰特性进行试验研究的情况,提出了一些悬式绝缘子在不同电压下无线电干扰水平的范围,并指出悬式绝缘子的无线电干扰水平取决于表面电晕和局部放电,而电晕和局部放电主要与绝缘子的结构尺寸及钢脚部位的胶装情况有关。

Gaoya dianqi为了研究带电污秽颗粒对绝缘子表面积污、电场分布的影响及空气域电晕放电现象，以FXBW-35/70绝缘子为研究对象，采用多物理场耦合有限元软件Comsol Multiphysics搭建了AC-DC、湍流、带电颗粒相互作用及颗粒运动的耦合风洞模型，进行了带电颗粒对绝缘子表面积污、电场和空气域电晕放电分布研究。结果表明：风速越大，迎风区积污速度快于其他区面；粒径增大时，迎风面积污严重，背风区积污很小，侧风区基本无变化；染污中迎风区伞裙表面的电位和电场畸变最为严重，背风区次之，染污后伞裙表面电位、电场有所缓和 ...
