标准摘要
[中文适用范围]： IEC 61439 的第 5 部分定义了公共电网配电成套设备（PENDA）的具体要求。PENDA 具有以下标准： - 用于在额定电压不超过 1 000 V 交流电的三相系统中分配电能（参见图 101 典型配电网络）； - 固定式； - 开放式（Open） - 适用于仅限熟练人员接触使用的场所，但户外型可安装在普通人可接触的场所； - 适用于室内或室外使用。 本标准的对象是列出定义并规定 PENDA 的服务条件、结构要求、技术特性和试验。网络参数可能需要更高层次的试验。 PENDA 还可包括与电能分配相关的控制或信号装置。 本标准适用于所有 PENDA，无论它们是单件设计制造还是完全标准化批量生产。 制造和/或组装可以由非原始制造商进行（参见 IEC 61439-1:2011 的 3.10.1）。 本标准不适用于符合相关产品标准的单个设备和独立组件，如电动机启动器、熔断器开关、电子设备等。 本标准不适用于由 IEC 61439 系列其他部分涵盖的特定类型成套设备。 [外文原描述]： IEC 61439-5:2014 defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria: - used for the distribution of electrical energy in three phase systems for which the rated voltage does not exceed 1 000 V a.c. (see Figure 101 for a typical distribution network); - open ASSEMBLIES are not covered by this standard; - suitable for installation in places where only skilled persons have access for their use, however, outdoor types may be installed in situations that are accessible to ordinary persons; - for indoor or outdoor use. This second edition cancels and replaces the first edition published in 2010. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the latest edition: - confirmation that tests carried out on the most onerous PENDA are deemed to verify the performance of similar and less onerous assemblies of the same general construction and rating; - more precise timing/conditions for impact force withstand tests for PENDAs designed for operation in an arctic climate; - correction of the direction of the applied force in the static load test. This publication is to be read in conjunction with IEC 61439-1:2011 . The contents of the corrigendum of March 2015 have been included in this copy.
