摘要
输电线路绝缘子的电压和电场分布对绝缘子的相关设计和运行维护非常重要。根据绝缘子串电压分布曲线和线路绝缘子实测结果可判断出绝缘子串的劣化程度、绝缘子串的绝缘性能等电气特征。主要研究玻璃绝缘子串的电压与电场的分布。在总结静电场计算方法的基础上,根据绝缘子串计算模型的特点,选择了ANSYS有限元方法进行求解。
The voltage and electric filed distribution of the transmission line insulator strings is very important to the de-sign and operation and maintenance. According to the voltage distribution curve of insulator chain and the measured re-suits of the insulator, it can judge some electric-al characteristics , such as the degree of degradation and insulation per-formance of insulator strings. This paper mainly studies the voltage and electric field distribut-ion of glass insulatorstrings. According to the characteristics of the calculation model of insulator strings, this paper cho-ose ANSYS Finite El-ement Method to solve on the basic of method for calculating the electrostatic field.
