BS IEC 61643-32:2017描述了设备的选择、安装和协调原则 用于直流电压高达1500 V的光伏（PV）系统和交流侧的SPD 光伏系统的额定电压高达1000 V rms 50/60 Hz。光伏装置从一个光伏阵列或一组相互连接的光伏组件延伸而来 包括相关电缆和保护装置以及连接处的逆变器 配电盘或公用设施供电点中的点。IEC 61643的这一部分考虑了不同位置和不同类型光伏中使用的SPD 系统:位于建筑物顶部的光伏系统。位于地面的光伏系统类似于自由场发电厂，具有多个 接地和网状接地系统。光伏安装一词指的是这两种光伏系统。术语光伏发电 该设备仅用于地面上的扩展自由场多接地电力系统。 对于包括电池在内的光伏装置，可能需要额外的要求。交叉引用:IEC 61643-21:2000 IEC 61643-12:2008 IEC 60364-5-54: 2011IEC 61643-31:2018IEC 62305-4:2010ITU-T K20:2000（E）IEC 60364-5-53:2001IEC 61000-4-5:2014IEC 60364-4-44:2007/AMD1:2015IEC 60364-4-44:2007IEC 60364-7-712:2017ITU-T K21:2000（E）IEC 61643-11:2011IEC 62305-2:2010IEC 62305-2:2010IEC 62305-3:2010IEC 60664-1:2007IEC 61643-22:2015IEC 62305-1:2010IEC 6206:2006EC当前购买的所有修改件都包括在IEC 61643:62903中购买本文件。

BS IEC 61643-32:2017 describes the principles for selection, installation and coordination of SPDs intended for use in Photovoltaic (PV) systems up to 1 500 V DC and for the AC side of the PV system rated up to 1 000 V rms 50/60 Hz.The photovoltaic installation extends from a PV array or a set of interconnected PV-modules to include the associated cabling and protective devices and the inverter up to the connection point in the distribution board or the utility supply point.This part of IEC 61643 considers SPDs used in different locations and in different kinds of PV systems:PV systems located on the top of a building.PV systems located on the ground like free field power plants characterized by multiple earthing and a meshed earthing system.The term PV installation is used to refer to both kinds of PV systems. The term PV power plant is only used for extended free-field multi-earthed power systems located on the ground. For PV installations including batteries additional requirements may be necessary.Cross References:IEC 61643-21:2000IEC 61643-12:2008IEC 60364-5-54:2011IEC 61643-31:2018IEC 62305-4:2010ITU-T K20:2000 (E)IEC 60364-5-53:2001IEC 61000-4-5:2014IEC 60364-4-44:2007/AMD1:2015IEC 60364-4-44:2007IEC 60364-7-712:2017ITU-T K21:2000 (E)IEC 61643-11:2011IEC 62305-2:2010IEC 62305-3:2010IEC 60664-1:2007IEC 61643-22:2015IEC 62305-1:2010IEC TR 62066:2002IEC 60904-3:2016IEC 62561All current amendments available at time of purchase are included with the purchase of this document.
