摘　　要：绝缘子串摆动引起的塔头与导线间的闪络事故和金具失效引起的线路故障越来越多,严重威胁输电系统的安全运行和正常供电。采用仿真平台建立输电线路绝缘子串精细化有限元模型,通过改变绝缘子的材料性能,得知不同材料绝缘子串对导线舞动影响较小,对导线风偏也起不到抑制作用。This nevertheless brings about continuously increasing occurrences of insulator string swaying-induced tower head-cable flashover accidents and equipment failure-induced line faults,which seriously threatens transmission systems′ safe operation and electric supply.This work briefly analyzed the span swaying of transmission lines whose insulator strings were made from various types of materials by establishing a finite element model of transmission line insulator strings.It found that the material type of insulator string could hardly influence line span swaying and could not suppress wind-induced swing.
