备用电池第2-100部分:备用电池模块安全

[中文适用范围]： IEC 62282 标准的第 2-100 部分提供了燃料电池模块在结构和正常运行及异常条件下运行以及测试的安全相关要求。它适用于具有以下电解质化学的燃料电池模块：碱性；聚合物电解质（包括直接甲醇燃料电池）；磷酸；熔融碳酸盐；固体氧化物；盐的水溶液。燃料电池模块可提供带或不带外壳，并且可以在显著加压水平或接近环境压力下运行。本文件涉及可能导致人员危险并在燃料电池模块外部造成损害的条件。本文件不解决燃料电池模块内部损害的防护，前提是这种损害不会导致模块外部的危险。这些要求可由其他包含燃料电池模块的设备标准取代，具体取决于特定应用需求。本文件不涉及燃料电池道路车辆应用。本文件无意限制或抑制技术进步。采用与本文件要求详述的材料或具有不同构造形式的设备，可根据这些要求的目的进行检验和测试，如果被认为是实质上等效的，可被视为符合本文件。燃料电池模块是最终产品的组成部分。这些产品需要根据适用的最终产品安全要求进行评估。 [外文原描述]： IEC 62282-2-100:2020 provides safety related requirements for construction, operation under normal and abnormal conditions and the testing of fuel cell modules. This document deals with conditions that can yield hazards to persons and cause damage outside the fuel cell modules. Protection against damage inside the fuel cell modules is not addressed in this document, provided it does not lead to hazards outside the module. These requirements can be superseded by other standards for equipment containing fuel cell modules as required for particular applications. This first edition cancels and replaces IEC 62282-2, published in 2012. This edition includes the following significant technical changes with respect to IEC 62282­2:2012: • update of definitions, in particular fuel cell module for normal operation; • leakage values under normal and abnormal operation have been addressed; • a delayed ignition test has been included; • protective measures to limit gas leakage have been included; • the requirements for insulation between live parts and SELV have been updated; • the general safety strategy has been modified to reflect the needs for different application standards; the modifications are in line with similar modifications made to IEC 62282­-3-­100; • the electrical components clause has been modified to reflect the needs for different application standards; the modifications are in line with similar modifications made to IEC 62282-3-100; • protective earthing as part of the module or bonding as a measure within the installation has been introduced; • a dielectric strength test has been completely updated by referring to IEC 62744-1 for voltages up to 1 000 V AC/1 500 V DC; • a new “pressure drop method” leakage test method has been included; • a new Annex addressing significant hazards, hazardous situations and events dealt with in this document, and linked to 4.1 (General safety strategy) has been added. The contents of the corrigendum of November 2023 have been included in this copy.
