标准范围

IEC 62548:2016规定了光伏（PV）阵列的设计要求，包括直流阵列布线、电气保护装置、开关和接地规定。范围包括光伏阵列的所有部件，包括但不包括储能装置、功率转换设备或负载。例外情况是，与电源转换设备相关的规定仅适用于涉及直流安全问题的情况。还包括用于连接光伏组件的小型直流调节装置的互连。本文件的目的是解决光伏系统特殊特性引起的设计安全要求。直流系统，尤其是光伏阵列，除了传统交流电力系统产生的危害外，还造成了一些危害，包括产生和维持电流不大于正常工作电流的电弧的能力。

IEC 62548:2016 sets out design requirements for photovoltaic (PV) arrays including DC array wiring, electrical protection devices, switching and earthing provisions. The scope includes all parts of the PV array up to but not including energy storage devices, power conversion equipment or loads. An exception is that provisions relating to power conversion equipment are covered only where DC safety issues are involved. The interconnection of small DC conditioning units intended for connection to PV modules are also included. The object of this document is to address the design safety requirements arising from the particular characteristics of photovoltaic systems. Direct current systems, and PV arrays in particular, pose some hazards in addition to those derived from conventional AC power systems, including the ability to produce and sustain electrical arcs with currents that are not greater than normal operating currents.
