摘要
随着变电站综合自动化改造的实施,变电站弱电系统的防雷保护日显重要。从分析雷电入侵变电所弱电系统的两种途径入手,对可能出现的雷电过电压进行仿真计算,对电涌保护器配置提出了一些意见,为变电所弱电系统防雷设计提供参考。
With the reconstruction of integrated substation automation, it＇s more and more important to protect the secondary equipments against the lightning electromagetic impulses. A computational analysis about the overvoltage probably occurring on the secondary equipments was dealt with according to two ways of substation being intruded by the lightning surge. As a result, several advices about the location schemes of surge protective device were proposed to make the design of lightning protection for substation secondary equipments.
