摘要
对复合绝缘子的缺陷类型、缺陷尺寸和缺陷位置进行仿真计算,获得伞裙沿面的轴向、径向电场分布曲线,计算出伞裙沿面轴向、径向电场的畸变率和最大场强值。结果表明:径向电场对于缺陷的反应更灵敏,通过分析伞裙沿面高压端和低压端径向电场分布规律,能够得到复合绝缘子缺陷的位置与类型等相关信息。
The type,size,and location of defects on composite insulator were simulated to obtain the axial and radial electric field distribution curves along the insulator shed,and then the distortion rate and the maximum field intensities of axial and radial electric field were calculated.The results show that the radial electric field is more sensitive to the defect.The types and location of defects can be obtained by analyzing the radial electric field distribution along the insulator shed.
