摘要

在建立输电线路防雷计算模型的基础上

用电磁暂态计算程序对有、无避雷线的35 kV输电线路避雷器的雷电放电电流和吸收的雷电放电能量进行了计算。具体计算了不同幅值的雷电流作用下

不同冲击接地电阻时

线路上避雷器的放电电流和吸收的比能量

讨论了雷电流、接地电阻对放电电流和比能量的影响

并对分别装在有、无避雷线的输电线路上的避雷器的放电电流和比能量进行了纵向比较分析。

Abstract

Based on the lightning overvoltage analysis model of transmission line

the absorbed discharging energy and lightning discharging current of line arresters on 35 kV transmission lines with and without shielding wires are analyzed by electromagnetic transient analysis program when the line surge arresters are applied to improve the lightning protection effect of transmission line.When the lightning respectively strikes on towers and transmission lines under varied conditions

such as different impulse grounding resistance and different lightning current

the lightning discharging current of arrester and the absorbed lightning discharging energy are calculated

and the influence of grounding resistance and lightning current on them are discussed.At the same time

the absorbed discharging energy and lightning discharging current are compared for 35 kV transmission lines with and without shielding wires in order to conclude the influence of shielding wires.
