光伏电站怎么才能选到合适的SPD？光伏电站大多分布于空旷的平原或者是山区，容易受到雷电的影响。雷电对光伏电站造成的影响，可以分为两种“直击雷”和“感应雷”。直击雷可以通过安装避雷针和避雷带的方式加以避免，防止感应雷入侵一般会在接线盒及PCS中配备感应雷浪涌电压的避雷器(SPD)。全国服务热线：400-0571-185。

避雷器的组成、原理和分类防雷器的基本元件有：放电间隙、气体放电管、变阻器、抑制二极管和扼流圈。根据其工作原理，可分为电压开关型SPD、限压型SPD和组合型SPD。其工作原理是：限制接入电力线和信号线的瞬时过电压设备能承受的范围，或向地面引入强雷击电流，以保护被保护设备或系统不受冲击损坏。防雷器全国服务热线：400-0571-185

在安装网络避雷器时，应注意信号避雷器内外的连接要求。进出网络避雷器不一定与信号传输方向一致。正确的连接方法是将网络避雷器的输入(IN)连接到信号通道，网络避雷器的输出(OUT)连接到保护装置，这是不可逆转的。网络避雷器的规范一般包含避雷器的技术参数和避雷器的维护和安装说明。在实际安装时，请仔细阅读相应的说明。网络避雷器全国服务热线：400-0571-185
