摘要

利用三维电场分析软件COULOMB计算了湿非陶瓷绝缘子的电场和电位分布。分析了扁平疏水硅橡胶(SIR)片上水滴表面的电场强度。水滴的导电性也是电场增强的一个重要因素。在雨或雾条件下，计算了绝缘子雨棚上水滴对电势分布的影响。还给出了几种典型情况(干净、雨和雾)的等势线图。

Electric field and potential distributions along non-ceramic insulators with water droplets

The electric field and potential distributions along wet nonceramic insulators are calculated using COULOMB, a three-dimensional electric field analysis program. The electric field intensification on the surface of the water droplets on a flat hydrophobic silicone rubber (SIR) sheet is analyzed. The conductivity of the water droplets is also an important factor in the electric field intensification. Under rain or fog conditions, the potential distributions influenced by the water droplets on the weathershed of the insulator are calculated. The plots of equipotential lines for a few typical cases (modeling dry-and-clean, rain, and fog conditions) are also shown.
