摘要

研究了空气和雾组成的气液混合两相体在球-球电极中的直流击穿电压。实验结果表明:"!电极上的水滴会使击穿电压降低

在准均匀和非均匀电场中

降低的比例差别不大;随着喷雾量的增加

降低的比例增加;"#空气中的雾会使击穿电压提高

在准均匀电场中（间隙较小时）

提高的比例较大

而且随着雾量的加大

提高的比例增加;在非均匀电场中（间隙较大）

提高不明显。

Abstract

This paper investigates the DC breakdown voltage in the two-phase mixture that is composed of air and mist. The experiment result shows that the water drop can reduce the breakdown voltage

there’s few difference in the ratio of dropping in uniform and non-uniform electric field;the bigger the mist flux is

the higher the breakdown voltage is. It also finds that gap length has influence on the effect of mist. And the liquid layer on the electrode surface can decrease the breakdown voltage.
