摘要
分析了地处多雷区的沿海变电所遭受雷击的特点,介绍了雷电侵袭供电网的三种形式;论述了变电站防雷的三道防线,以及站内重要电气设备如断路器、变压器、电抗器等的防雷保护,探讨了变电所的接地技术,并对此类变电站的防雷设计提出了一些建议。
Analysis was made to the lightning features of substations located in coastal areas with lots of lightning. Introduction was made to three kinds of forms of power supply nets invaded by lightning. Discussion was made on three proof-lines of substation lightning-proof, and lightning-proof for important electric equipment within station such as circuit breakers, transformers, reactors etc, as well as the grounding techniques of substations. Some suggestions were raised for this kind of substation＇s lightning-proof design.
