光伏系统的直击雷和瞬态过电压保护

确保光伏系统安全运行

雷暴所产生的电涌是光伏系统损坏的最常见的原因

涌经常导致系统损坏,如组件、逆变器、监视系统等部分。这部分的经济损失是非常可怕的。替换损坏的逆变器,安装新的光伏系统的硬件成本,设备停机所造成的发电损失…… 这意味着利益平衡点被打破,成本回收将延迟。

完整专业的防雷系统包含以下部分:

  • 外部防雷:包含接闪系统,引下线
  • 内部防雷:包含电涌保护和雷电等电位连接

完整的防雷系统才能确保光伏系统长期持续安全运营并确保营收。

屋顶光伏系统

专业防雷规划设计

屋顶光伏系统是最常见的光伏系统之一。由于所处暴露的安装位置,屋顶光伏系统特别容易遭受直接雷击和间接雷击的破坏。

因此,屋顶光伏系统需要全面的防雷保护。

根据三个不同的应用场景,请参考不同的解决方案:

  • 建筑没有设置外部防雷保护
  • 建筑设置了外部防雷保护,并且满足隔离距离要求
  • 建筑设置了外部防雷保护,但并不满足隔离距离要求

地面光伏系统和光伏电站

直击雷和瞬态过电压的保护

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

在地面光伏系统中,按结构可分为两种,集中式地面电站配置集中式逆变器;分布式地面电站配置组串式逆变器。

储能系统

储能系统用于储存光伏系统的额外电量,并在需要时并入电网中使用。平衡峰谷用电需求。

电涌,直击雷危害和电网电压波动会对储能系统造成损坏风险。

减少昂贵的维护和维修时间。保障储能系统稳定运行。定制全面的雷击及电涌保护方案。
