摘要

采用介质涂覆的球-板电极结构

研究了不同电导率、气压和脉冲电压幅值条件下水中流注放电的特性.结果表明

水的电导率和脉冲电压幅值对水中流注速度、图像亮度等有较大影响.不同电导率条件下

气压由0.1 MPa降至0.006 5 MPa对水中超音速流注发展平均速度并无明显影响.在低气压时

纯净水中间隙为10%击穿电压(U

)降低

约为一个大气压条件下的80%

而在高电导率的水中

几乎不受气压影响.由放电图像和放电电流波形分析可知

在低电导率的水中

流注发展是不连续的分步发展

在每一步的发展中形成一个或多个微小的气泡.

Abstract

Adopting a dielectric-coated electrode configuration

the characteristics of streamer discharge in water with different conditions such as conductivity

ambient pressure

and voltage amplitude are investigated under pulse voltages. The experimental results demonstrate that water conductivity and applied voltage amplitude exert a great influence on mean velocity and brightness of the streamer discharge. When the ambient pressure decreases from 0.1 MPa to 0.006 5 MPa

the pressure affects slightly the mean velocities of the supersonic streamer in both distilled and tap water. Also

the 10% breakdown voltage(U

)is decreased by 20% in distilled water under the pressure of 0.006 5 MPa than that under the pressure of 0.1 MPa

while in tap water the U

is almost the same under different pressures. Based on the analysis of the discharge images and current waveforms

it can be concluded tha

t the streamer development in low conductivity water gets discrete and steps forward.
