标准摘要
[中文适用范围]： 本文件适用于用于光伏(PV)系统电路中直流电弧的检测和可选中断的设备。文件涵盖了光伏电路中串联电弧的检测程序，以及用于中断电弧的设备的响应时间。 文件定义了进行测试的参考场景。本文件涵盖连接到系统不超过最大光伏源电路电压1500 V DC的设备。 并联电路电弧的检测不在本文件范围内。本文件不适用于除光伏直流源以外的直流源或应用。 注：并联电弧检测可能会在未来的版本中考虑。 [外文原描述]： IEC 63027:2023 applies to equipment used for the detection and optionally the interruption of electric DC arcs in photovoltaic (PV) system circuits. The document covers test procedures for the detection of series arcs within PV circuits, and the response times of equipment employed to interrupt the arcs. The document defines reference scenarios according to which the testing is conducted. This document covers equipment connected to systems not exceeding a maximum PV source circuit voltage of 1 500 V DC. This document provides requirements and testing procedures for arc-fault protection devices used in PV systems to reduce the risk of igniting an electrical fire.
