摘要

通过实验研究了正棒-板电极间隙中气液混合体直流电晕放电的形态及其伏安特性

结果表明

不仅在棒电极头部有电晕放电现象发生

而且棒电极上的水滴表面也会产生较强的电晕放电。在相同电压作用下

自来水-空气混合体的放电电流最大

纯净水-空气混合体的次之

单纯空气的最小。电流的增大主要与液滴的电导率、运动液滴对局部电场的畸变及对空间电荷的破坏等作用有关。

Abstract

Through the study of positive corona discharge phenomenon in gas-liquid mixture and the rule of voltage-current curve in DC voltage

it is found that corona discharge can occur both in the rod electrode and in the drops on the rod electrode. Under the same voltage

the tap water-air mixture can bring the strongest discharge current

the pure water-air is the second

and the pure air is the least. The increase of current mainly relates to the conductivity of liquid

the distortion of partial electric field and the destruction to space charge by the moving drops.
