摘要
文章说明了雷直击变电站时如何对其控制室内的弱电设备造成干扰，并分析了雷击控制室防雷系统时，影响室内回路中暂态感应电压幅值的各种因素。最后以平果５００ｋＶ变电站为例，说明雷击变电站控制室防雷系统时对弱电设备的影响及防护措施。研究表明，变电站设计时应尽量使有引雷作用的建筑物（如消雷器）远离控制室和计算机室；建筑物防雷系统设计时，不应单纯追求对称布置和均矩布置，应根据实际情况采用最优方案。
This paper describes how direct lightning stroke against substation disturbs the electronic devices in control building. Various factors affecting the magnitude of transient voltage induced in indoor loop are analyzed when the lightning protection system(LPS) for control building is directly stricken. Finally, taking the 500kV Pingguo substation as an example, the affection on electronic devices caused by lightning stroke against LPS is demonstrated and the adequate protection measurements are presented.
