标准摘要
[中文适用范围]： 第 1 部分的本条款在添加以下内容后适用。补充：本标准给出了公共电网配电组件（PENDA）的具体要求，公共电网配电组件是通过验证测试验证的固定组件，如本标准所定义。这些组件用于三相系统中的电能分配（参见图 101 的典型配电网络）。本标准不包括开放式组件。本标准的目的是阐述 PENDA 的定义并规定其使用条件、施工要求、技术特性和测试。网络参数可能需要更高性能级别的测试。注 1：如果 PENDA 配备了附加设备（例如仪表），其主要功能发生了相当大的变化，则按照用户和制造商之间的协议，其他标准也可适用（见 8.5）。注 2：在当地法规和实践允许的情况下，符合本标准的 PENDA 可以用于公共网络以外的其他网络。 PENDA 适合安装在只有技术人员才能使用的地方，但是，户外类型可以安装在普通人可以接触到的地方。 [外文原描述]： IEC 61439-5:2010 gives specific requirements for public electricity network distribution assemblies (PENDAs), which are stationary assemblies verified by verification tests, as defined in this standard. These ASSEMBLIES are used for the distribution of electrical energy in three-phase systems (see Figure 101 for a typical distribution network). Open type ASSEMBLIES are not covered by this standard. This first edition of IEC 61439-5 cancels and replaces the second edition of IEC 60439-5 (2006), and constitutes a technical revision. This edition of IEC 61439-5 includes the following significant technical changes with respect to the latest edition of IEC 60439-5: - alignment on IEC 61439-1 regarding the structure and technical content, as applicable; - introduction of new verifications, accordingly; - harmonisation of the requirements of substation cable distribution boards and cable distribution cabinets, thereby eliminating the need to identify and define two catagories of assembly; - simpler standard as a result of a reduction in the number of assembly types defined and the acronyms used to identify the different assemblies. This publication is to be read in conjunction with IEC 61439-1:2009 .
