电动汽车充电桩的雷击风险与防护

Lightning strike risk and protection of charging piles for electric vehicles

该文结合充电桩系统的组成结构、工作原理对充电桩遭受雷击的风险进行分析。同时,参照IEC、GB等有关防雷标准,在总结实践经验的基础上有针对性地提出了充电桩选址建议、防雷分类、直击雷防护、防雷等电位连接、屏蔽和合理布线、安装SPD、共用接地以及科学管养等多项综合防护措施,确保充电桩防雷安全。

This paper analyzes the risk of lightning strike on the charging pile based on the composition and working principle of the charging pile system. At the same time, with reference to follow the standards of IEC, GB and so on lightning protection, on the basis of summarizing the practical experience with charging pile location selection,suggestions were put forward in view of the classification of the lightning protection, lightning protection and lightning protection equipotential connection, shielding and reasonable wiring, installation of SPD, common ground as well as a number of comprehensive protection measures of the scientific custody, ensuring the safety of charging piles lightning protection.
