Introduction of GB/T 18802.31-2021

GB/T 18802的本部分适用于对雷电的间接和直接效应或其他瞬态过电压的电涌进行保护的电涌保护器（SPD)。这些SPD将被连接到额定电压不超过1 500 V的光伏系统的直流侧。?
这些SPD至少包含一个用来限制电压和泄放电涌电流的非线性的元件。本部分规定这些电器的性能特性、安全要求、标准试验方法和额定值。?
符合本部分的SPD仅仅是设计用来安装在光伏系统直流侧和逆变器的直流侧。?
用于储能光伏系统（如电池，电容组)的SPD不包含在本部分中。?
在分开的输入和输出端子之间有特殊的串联阻抗的SPD (IEC 61643-11:2011中所谓的二端口SPD)目前不包含在本部分中。?
符合本部分的SPD是只能用工具来连接和断开的永久连接的固定式SPD。本部分不适用于移动式SPD。?
注1: 对于应用于光伏系统的SPD，出于对电源效率的考虑，输入和输出端子之间通常不包含特殊的串联阻抗。?
注2: 凡在本部分中提到的电力系统或者电网，都是指光伏系统的直流侧。
