摘要
介绍了为研究大间距水中脉冲电晕放电建立的放电模型和实验系统。理论和实验结果分析证明水中电晕放电为过阻尼过程,无振荡,无二次放电。采用高速摄影仪研究放电及气泡的运动过程发现,放电仅在高压电极端部形成球形等离子体,不存在贯通的电弧通道,产生的气泡无二次涨缩过程。
The pulsed corona discharge in water is presented, and its model is founded and the experimental system is designed. The composition of experimental system, experimental results and analytical results are presented. Both theoretical and experimental .results prove that the discharge is an over damping process, there＇s no phenomena of vibration and second discharge. Pictures are taken by high--speed photography. The fork plasma produced by discharge only exists at the tip of the discharge electrode, not pass through the two dectrodes. The bubble doesn＇t expand andshrink secondly.
