核电厂 仪控系统和电力系统 静态不间断直流和交流供电系统要求

[中文适用范围]： IEC 61225:2025 RLV包含官方的IEC国际标准及其红线版本。红线版本仅提供英文版，便于用户快速直观地比较当前IEC标准与其前一版之间的所有变更。IEC 61225:2025规定了核电站（NPP）中低压静态不间断电源（SUPS）系统的性能和功能特性，并在适用时也适用于一般核设施。不间断电源（UPS）是一种电气设备，它从电源获取电能，将其储存，并通过设备内部的装置将其以指定形式输送至输出端。SUPS在执行其功能时不包含任何旋转部件。电源系统组件的具体设计要求由IEC标准及其他规范性参考中列出的标准涵盖。否则，具体组件级别的设计要求不在本文件的范围内。 [外文原描述]： IEC 61225:2025 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 61225:2025 specifies the performance and the functional characteristics of the low voltage static uninterruptible power supply (SUPS) systems in a nuclear power plant (NPP) and, when applicable, in nuclear facilities in general. An uninterruptible power supply (UPS) is an electrical equipment which draws electrical energy from a source, stores it, and maintains the supply in a specified form by means inside the equipment to output terminals. A SUPS has no rotating parts to perform its functions. The specific design requirements for the components of the power supply system are covered by IEC standards and other standards listed in the normative references. Otherwise, specific component-level design requirements are outside the scope of this document.
