摘要

利用光电电场传感器对复合绝缘子表面场强的分布进行了测量

采用平行金属板对研制的电场传感器进行了工频标定实验

并测量了绝缘子棒身表面附近的轴向电场和伞裙下方的径向电场分布。对绝缘子和连接金属导体进行了建模

并利用边界元法计算了绝缘子表面场强的分布

计算结果和测量值基本符合。

Abstract

This paper introduces an optical electric field sensor for the measurement of electric field distribution on composite insulator surface.The developed sensor is calibrated between two parallel metal plates under power frequency.The measurement of z-direction electric field on glass rod surfaces and r-direction electric field beneath weathersheds is carried out.Geometrical model is built and electric field on the surface of insulator is calculated by using boundary element method（BEM）.The results show good agreement between the measurement and calculated data.
