Abstract

Insulators for overhead lines are considered to be of basic importance to the transmission system. This paper describes a new method to check defective ceramic insulators by finding the solution of the inverse problem in the system containing insulators strings. Measure the electric field of given points in the vicinity of high voltage insulators string, calculate the voltage distribution of the insulators by charge simulation method (CSM) and Newton method. Compare it with normal voltage distribution to check whether there are defective insulators in the string and the position of them

提出了一种利用电荷模拟法检测陶瓷绝缘子缺陷的新方法
架空线路的绝缘子被认为是输电系统的重要基础。本文提出了一种通过求解含绝缘子串系统的反问题来检测陶瓷绝缘子缺陷的新方法。测量高压绝缘子串附近给定点的电场,用电荷模拟法(CSM)和牛顿法计算出绝缘子串的电压分布。与正常电压分布比较,检查串中是否有不良绝缘子及其位置
