核电厂.仪表 控制和电力系统.静态不间断直流和交流电源系统的要求

[中文适用范围]： 本文件规定了核电厂(NPP)及一般核设施中低压静态不间断电源(SUPS)系统的性能和功能特性。不间断电源(UPS)是一种从电源获取电能、储存电能并通过设备内部手段将电能以指定形式输出到输出端子的电气设备。静态不间断电源(SUPS)没有旋转部件来实现其功能。 电源系统组件的具体设计要求由IEC标准和其他规范性引用文件中列出的标准涵盖。否则，组件级的具体设计要求不在本文件范围内。 [外文原描述]： 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.
