摘要
提出了一种电晕耦合无声放电结构,通过对线-板式电晕耦合无声放电结构静电场进行数值模拟,得出了不同线-板电极配置下的电场分布,结合流光形成、发展和传播所需的静电场条件,分析了电极配置。结果表明,对于一定的放电电压和线-板间距,存在一个较优的线电极直径,使之既满足于电晕放电的起晕,又满足于流光放电的发生、发展及稳定传播。对于一定的线-板间距,线-线间距存在一个有效范围。
A corona coupling silent discharge structure is put forward and the distributions of electrical field on different electrode configurations are calculated by the numerical simulation of electrostatic field of the line-plate coupling structure. The electrode configuration is analyzed by combining the static electric field conditions for streamer corona forming, developing and propagating. Results show that there is an optimum line electrode diameter for one certain discharge voltage and line-plate spacing. This optimum diameter satisfies the forming of corona, and satisfies the developing and propagating of streamer corona. Furthermore, there is an effective range of line-line spacing for one certain line-plate spacing.
