摘要

本文考察了用细金属丝密绕于光滑电极表面上

来模拟连续半园柱微观突出粗糙表面的实际可行性

定量计算及实验了这种表面在SF

中的表面粗糙度效应

计算曲线与实验结果非常接近。这表明

只要计算模型与实验电极一致

电极表面的连续微观突出对SF

气体放电的影响

可根据流注判据定量预测。

Abstract

This paper investigates into feasibility of forming multiple semicylindrical protrusions by winding a thin wire on the electrode surface.Computational and experimental results for this surface roughness model are in good agreement

which shows that prediction of the effect of multi-protrusions on breakdown of SF6 is porsible

if the roughness model used in computation is in accordance with the surface condition of the electrode
