地面光伏系统和光伏电站的雷击及电涌保护

保护光伏电站免受直击雷和瞬态过电压的破坏

地面光伏系统和光伏电站的防雷系统有两个目标:

  • 保护光伏电站区域免受雷电引起的破坏
  • 保护组件,逆变器,监控系统免受电磁脉冲的影响

由于投资总量高,运营商需要保证电站的长期稳定运行。因为这个原因,雷电相关风险应根据IEC 62305-2进行分析及计算。风险分析是提供防雷系统规划的基础。

降低现有光伏系统的风险

现有光伏系统往往无法防止直击雷及电涌的侵袭。我们可以提供合适的产品用于升级整体防雷系统,帮助您找到一个合理的解决方案 请直接与我们联系!

集中式地面电站配置集中式逆变器

案例 1

直流电缆从直流汇流箱导出,经过光伏电站区域连接到集中式逆变器。

标准规定和说明:标准DIN EN 62305-3补充条款5中规定,地面光伏系统在LPS III和接地系统网格为20 x 20 m情况下,电压限制或复合型1级SPD的最小放电能力。在选择直流侧的1级SPD时,必须遵守此标准的要求。

全面保护电子元件

1+2级复合型电涌保护器安装在逆变器的直流侧和汇流箱中。此外,1级复合型电涌保护器用于保护逆变器的交流侧。数据通讯接口也需要采用电涌保护器进行保护。

直击雷保护

接闪系统用于保护光伏组件免受直击雷破坏。光伏组件专用接闪短针可以固定在光伏支架上。

分布式地面电站配置组串式逆变器

案例 2

光伏电站应用分布式方案,大量的交流电缆会经过电站区域连接组串式逆变器到交流汇流箱或者箱变侧。
