Abstract

Suspension insulator string is widely used as insulator structures in high voltage overhead power lines. Power frequency voltage of feed line is distributed along string elements in unequal amounts due to parasitic capacities (on ground and wire). Grading rings arrangement close to current-conducting elements is one of the most effective ways for voltage grading. The results of investigation of voltage distribution along insulator string based on the following models set are presented in the article: real string in high voltage laboratory, string physical model based on lumped elements, mathematical model in software package. Two-dimensional axially symmetric model of insulator string based on finite element analysis was developed in ActiveField software package. The results of optimality calculation for selection of grading ring arrangement height are presented and analyzed. Comparison and analysis of theoretical and experimental data were carried out on the base of investigation results.

一套研究悬架绝缘子串电压分布的模型

悬挂式绝缘子串是高压架空输电线路中广泛使用的绝缘子结构。馈线工频电压由于寄生容量(在地面和导线上)的影响，沿串元件分布不均。在导流元件附近布置分级环是进行电压分级最有效的方法之一。本文介绍了基于以下模型集的绝缘子串电压分布的研究结果:高压实验室中的真实串、基于集总元的串物理模型、软件包中的数学模型。在ActiveField软件包中建立了基于有限元分析的二维绝缘子串轴对称模型。给出并分析了分级环布置高度选择的优化计算结果。在研究结果的基础上，对理论数据和实验数据进行了对比分析。
