摘要
高海拔情况下,低气压和覆冰使绝缘子电气性能降低,冰闪电压与绝缘子串布置方式有关,水平布置时冰闪电压最高,V型布置方式次之,垂直布置方式时冰闪电压最低,采用"3+1"和"4+1"间插布置方式且大盘径绝缘子的盘径比参考盘形悬式绝缘子大100-150mm时,具有较好的防冰效果;合理的间插布置方式可以提高覆冰绝缘子串交流冰闪电压15%-20%。
Under the condition of high altitude, low air pressure and reduce the electrical performance of icing insulator, flashover voltage and insulator string arrangement on horizontal when the icing flashover voltage is the highest, V layout of the vertical arrangement of the icing flashover voltage is the lowest, with ＂3＋1＂ and ＂4＋1＂ are inserted between the layout and the market the diameter of disc insulator diameter than the reference disc suspension insulator 100-150 mm, with anti icing effect is good; reasonable arrangement can be inserted between the increase of iced insulators AC flashover voltage 15%-20%.
