标准摘要
[中文适用范围]： 本标准规定了公共电力网络配电组件（PENDAs）的具体要求。PENDAs具有以下标准： - 用于三相系统中额定电压不超过1000V AC和DC系统不超过1500V DC的电能分配； - 固定式； - 不适用于开放式组件； - 适合安装在只有专业人员才能进入的地方，但户外类型可以安装在普通人可以进入的场所。 本文件的目的是规定PENDAs的定义、使用条件、结构要求、技术特性和测试。PENDAs还可以包括与电能分配相关的控制和/或信号设备。 本标准适用于所有PENDAs，无论它们是按一次性设计制造还是完全标准化并批量生产。制造和/或组装可以由原始制造商以外的其他方进行。 本标准不适用于符合相关产品标准的单个设备和自包含组件，如电机启动器、熔断开关、电子设备等。如果变电站由公共配电系统运营商（DSO）拥有或运营，则用作变压器变电站低压配电盘的PENDAs在本标准范围内。 本标准不适用于IEC 61439系列其他部分涵盖的特定类型组件。 [外文原描述]： IEC 61439-5:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61439-5:2023 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 AC (see Figure 101 for a typical distribution network) and DC systems not exceeding 1 500 V DC; - stationary; - open type assemblies are not covered by this document; - suitable for installation in places where only skilled persons have access for their use, however, outdoor types can be installed in situations that are accessible to ordinary persons - intended for use in energy distribution in public power grids; - indoor use: assemblies for installation inside of electric power substations; - outdoor use: assemblies containing an enclosure suitable for open air installation. This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) omission of the requirement to conduct mechanical tests at -25 °C when enclosures are made of a metallic material; b) addition of assumed loading factors generation supplies and electric vehicle charging applications; c) additional dielectric tests when a PENDA is used in a distribution substation with separate HV and LV earths; d) further clarification of representative samples for design verification. The content of the corrigendum 1 (2025-02) has been included in this copy.
