消电管中集流放电针截面形状对消电效果影响的研究

The research on the discharge effect of cross-section shapes of discharging needle in electrostatic eliminating tube

本文对消电管中集流放电针的形状与消电效果之间的关系进行了研究。采用FEM的方法,对同一尺度的三种不同截面的集流放电针在空间中形成的静电场进行了仿真。分析了两个特定方向上的电场强度分布,并对电场强度与消电效果之间的关系进行了讨论。结果表明,其中截面为三角形的集流放电针在几个特定方向上电场强度的平均值最高,对静电的消除效果最好。

This paper has a research on the relationship between discharging effect and the shape of discharge needle in discharge tube. This paper use the finite element method, which simulate the electrostatic fields generated by three kinds of different cross-section discharge needles that have the same size, then analyses the electric intensity distribution in two particular directions and discusses the rela- tionship between electric intensity and discharging effect. The results shows that, the discharge needle having a small angle triangle cross- section have the highest average electric intensity in several specific directions, and have the best effect on discharging.
