330kV输电线路防鸟害绝缘护套仿真分析及应用

为研究330 kV输电线路安装绝缘护套的防鸟害效果,采用Ansoft对330 kV线路复合绝缘子的轴向电位和电场分布进行仿真分析。结果表明:对330 kV输电线路而言,当绝缘护套厚度为1 cm、导线夹有效长度为50 cm时,防鸟害效果最佳;将导线、金具和均压环都包覆在内时,绝缘子高压端电场分布最优。最后结合仿真分析结果,对输电线路防鸟害绝缘护套的现场应用提出了建议。

Simulation analysis and application of insulation sheath for bird damage preventing installed on 330 kV transmission line

In order to study the bird protection effect of installing insulation sheath on 330 kV transmission lines, An soft was adopted to simulate and analyze the axial potential and electric field distribution of the composite insulator on 330 kV lines. The results show that when the insulation sheath thickness on 330 kV transmission line is 1cm and the effective length of wire clip is 50 cm, the bird damage prevention effect is the best. The electric field distribution at the high voltage end of the insulator is optimal when the conductor, metal fittings and pressure equalizing ring are covered by insulation sheath. Finally, some application suggestions of insulation sheath for bird damage preventing installed on transmission line were put forward based on the simulation results.
