摘要:
针对高压开关柜的尖端放电,首先,提出仿真分析局部放电问题时阈值判据的计算方法,并推导出电晕层厚度的计算公式;然后,考虑到湿度是影响高压开关柜局部放电的重要因素,通过实验数据拟合,得到电晕起始电压随相对湿度的变化公式;最后,采用有限元分析软件进行尖端放电的电场计算与分析,并通过尖端放电实验测试电晕起始电压.仿真实验结果表明:高压开关柜尖端放电的电场计算方法是正确的,且简便实用,有助于高压开关柜进行结构优化设计.
Abstract:
In this paper, the tip discharge in high-voltage switchgear was taken as the research object. Firstly, the calculation method of the threshold criterion for simulating the partial discharge problem was proposed and the calculation formula of the corona layer thickness was derived. Secondly, considering that the humidity is an important factor affecting the partial discharge in high voltage switchgear, the varying formula of the corona onset voltage with relative humidity was obtained by analyzing the experimental data. Finally, the finite element analysis software was used to calculate and analyze the electric field of tip discharge in high voltage swichgear, and the corona onset voltage was tested by the tip discharge experiment. The simulation experiment results show that the calculation method of the electric field at the tip discharge of the high voltage switchgear is correct, simple and practical, and it is helpful for the structural optimization design of the high voltage switchgear.
