IEC 63272:2024规定了现场交流可中断供电系统的性能和功能特点，适用于新建核设施和新安装或升级的现场交流可中断供电系统。 供电系统组件的具体设计要求由规范性参考文献中列出的IEC标准定义，不在本文件的范围内。 本文件的目的是为作为核设施整体配电系统一部分的现场交流可中断供电系统的设计提供高水平的要求。本文件定义了电气设计师建立核设施交流可中断电源设计的要求。它与1级标准IEC 63046结合使用。

IEC 63272:2024 specifies the performance and functional characteristics of the on-site AC interruptible power supply systems and applies to new nuclear facilities and newly installed or upgraded on-site AC interruptible power supply systems.
The specific design requirements for the components of the power supply system are defined by the IEC standards listed in the normative references and are outside the scope of this document.
The purpose of this document is to provide high level requirements for the design of on-site AC interruptible power supply systems as part of the overall electrical distribution system in a nuclear facility. This document defines the requirements for an electrical designer to establish the design of the AC interruptible electrical power supply for nuclear facilities. It is used in conjunction with Level 1 standard IEC 63046.
