标准摘要
[中文适用范围]: 本部分 IEC 62257 是一项技术规范,规定了用户安装中连接微电网或独立系统发电部分的接口设备的设计和实现的一般要求。 此接口是用户安装的一部分,如图1所示。 图1 - 电气化系统的一般配置 本部分 IEC 62257 适用于分散式农村电气化系统(DRESS)中最大功率为500 VA的简化用户接口(配电板)。 注:对于分散式电气化系统中功率超过500 VA的安装,适用 IEC TS 62257-5。 本部分 IEC 62257 适用于用户安装中的接口设备,该设备将用户安装连接到: - 240 V 或 230 V 或 220 V 或 120 V 交流微电网, - 独立安装的发电部分 - 交流或直流。 该设备提供保护、隔离和配电功能。 [外文原描述]: IEC TS 62257-9-3:2016(E) specifies the general requirements for the design and the implementation of the interface equipment within the user's installation which connects to a microgrid or the generating part of a standalone system. It applies to simplified user's interfaces (distribution board) in electrical installations with maximum power of 500 VA in decentralized rural electrification systems. The main technical changes with regard to the previous edition are as follows: changing the voltage range covered by the technical specification to AC nominal voltage below 1 000 V and DC nominal voltage below 1 500 V. This publication is to be read in conjunction with IEC 62257 series .
