标准摘要
[中文适用范围]： 这些补充要求适用于保护光伏（PV）字符串和光伏阵列的熔丝组件，用于标称电压最高达 1500 V DC 的电路设备中，并且，在适用范围内，也适用于标称电压更高的电路。其额定电压最高可达 1500 V。此类熔丝组件通常被称为“光伏熔丝组件”。在大多数情况下，相关设备的一部分充当熔丝底座。由于设备种类繁多，无法给出通用规则；相关设备作为熔丝底座的适用性应由制造商和用户协商确定。然而，如果使用单独的熔丝底座或熔丝支架，它们应符合 IEC 60269 系列的相关要求。光伏熔丝组件保护下游逆变器组件（如电容器）或电容器反向放电进入阵列或阵列布线直至额定分断容量。 [外文原描述]： IEC 60269-6:2010+A1:2021 gives supplementary requirement to those given in IEC 60269-1 for fuse-links for protecting photovoltaic (PV) strings and photovoltaic (PV) arrays in equipment for circuits of nominal voltages up to 1 500 V d.c. This consolidated version consists of the first edition (2010) and its amendment 1 (2021). Therefore, no need to order amendment in addition to this publication. This publication is to be read in conjunction with IEC 60269-1:2006 . The contents of the corrigendum of November 2021 have been included in this copy.
