标准摘要
[中文适用范围]: 本部分IEC 62257是一项技术规范,适用于具有以下特性的独立可再生能源产品: - 所有提供基本能源服务所需的组件作为套件或集成到单个组件中销售和安装,至少包括: - 电池、电池或其他能量存储设备 - 发电设备,如太阳能电池板,能够为电池、电池或其他能量存储设备充电 - 电缆、开关、接线、连接器和保护装置,足以连接发电设备、电源控制单元和能量存储设备 - 负载(可选),如照明、负载适配器电缆(例如用于移动设备)和电器(电视、收音机、风扇等)。 - PV模块的最大功率点电压和套件中任何其他组件的工作电压不超过35 V。对于符合适当安全标准的AC-DC转换器例外。 - PV模块或其他发电设备的峰值功率额定值小于或等于350 W。 - 不需要设计专业知识来选择适当的系统组件。 本文档主要针对电池和PV模块的离网可再生能源产品,直流系统电压不超过35 V,峰值功率额定值不超过350 W。本文档中的测试在许多情况下能够充分评估电压或功率额定值较高的系统。在指定组织同意将这些测试应用于电压和功率额定值较高的产品的情况下,测试实验室负责确保采取足够的安全措施来保护技术人员和测试设备。指定组织还负责定义这些产品的消费者安全要求。 本文档包括与安全相关的条款;然而,它不打算成为一个全面的安全标准。特别是,本文档不打算用作安全标准(如IEC 62368-1或IEC 60335(所有部分))的替代品,用于包含在独立可再生能源产品中的电器(如收音机和电视)。也不打算取代IEC 62281或UN 38.3对运输中电池安全的要求,或IEC 61730-1和IEC 61730-2对用于独立可再生能源产品之外的PV模块的安全要求。 本文档不涉及电磁兼容性(EMC)。现场经验表明,在本文档范围内的独立可再生能源产品的典型应用中,EMC不是一个主要问题。在EMC是一个问题的应用中(例如包括医疗设备的系统),应参考特定应用的相关标准。 [外文原描述]: IEC TS 62257-9-5:2024 provides support and strategies for institutions involved in rural electrification projects. It documents technical approaches for designing, building, testing, and maintaining off-grid renewable energy and hybrid systems with AC nominal voltage below 500 V, DC nominal voltage below 750 V and nominal power below 100 kVA. The purpose of this document is to specify laboratory test methods for evaluating the quality assurance of stand-alone renewable energy products. This document is specifically related to renewable energy products that are packaged and made available to end-use consumers at the point of purchase as single, stand-alone products that do not require additional system components to function. This document establishes the framework for creating a product specification, the basis for evaluating quality for a particular context. Product specifications include minimum requirements for quality standards and warranty requirements. This document applies to stand-alone renewable energy products having the following characteristics: This document was written primarily for off-grid renewable energy products with batteries and PV modules with DC system voltages not exceeding 35 V and peak power ratings not exceeding 350 W. This document includes provisions related to safety; however, it is not intended to be a comprehensive safety standard. In particular, this document is not intended to be used as an alternative to safety standards such as IEC 62368-1 or IEC 60335 (all parts) for appliances such as radios and televisions that are included with stand-alone renewable energy products
