本文件规定了核电厂低压静态不间断电源（SUPS）系统的性能和功能特征，对于适用部件，一般而言，还规定了核设施的性能和功能特征。不间断电源是一种电气设备，它从电源中提取电能，存储电能，并通过设备内部的方式将电能维持在指定的形式，以输出端子。静态不间断电源（SUPS）没有执行其功能的旋转部件。 IEC标准和规范性参考文件中列出的标准涵盖了电源系统部件的具体设计要求，其他方面不在本文件的范围内。交叉引用: IEC 62003IEEE 60780-323EN 62566HD 60364-4-41+A12:2019EN IEC 60709EN 60780-323EN 60146-2IEC 61508（所有部分）EN IEC 62138IEC 62040（所有部分）IEC 61000（所有部分）EN 60038HD 60364-41EN 61000-1EN 61508IEC 60980EN IEC 62040EN 60880IEC 60038EN 60146-1-1IEC 62566-2IEC 60364-41EN 61513HD 60364-41+A11:2017EN 61226IAEA-T-3.8IEC60964IEC 60479（所有部分）IEEE Std 946-2004IAEA 91EN 50272-2IEC 61000-6-4IAEA TECDOC 1770EN IEC 60964EN IEC 61000-6-2IEA SSG-34IEC 60364（所有部分）IEC 61226IEC 61000-6-2IEA SSG-39IEC 62040-31IEC 62340IEC 62040IEC 63046IEC 62671EN IEC 61000-6-4EN 62040-3组织如下:勘误表，2020年4月

This document specifies the performance and the functional characteristics of the low voltage static uninterruptible power supply (SUPS) systems in a nuclear power plant and, for applicable parts, in general for nuclear facilities. An uninterruptible power supply is an electrical equipment which draws electrical energy from a source, stores it and maintains supply in a specified form by means inside the equipment to output terminals. A static uninterruptible power supply (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 standards listed in the normative references and are otherwise outside the scope of this document.Cross References:IEC 62003IEEE 60780-323EN 62566HD 60364-4-41+A12:2019EN IEC 60709EN 60780-323EN 60146-2IEC 61508 (all parts)EN IEC 62138IEC 62040 (all parts)IEC 61000 (all parts)EN 60038HD 60364-4-41EN 61000-1EN 61508IEC 60980EN IEC 62040EN 60880IEC 60038IEC 62138EN 60146-1-1IEC 60709IEC 62566IEC 61513IEC 60880IEC 60146-1-1IEC 62566-2IEC 60146-2IEC 60364-4-41EN 61513HD 60364-4-41+A11:2017EN 61226IAEA NG-T-3.8IEC 60964IEC 60479 (all parts)IEEE Std 946-2004IAEA 91EN 50272-2IEC 61000-6-4IAEA TECDOC 1770EN IEC 60964EN IEC 61000-6-2IAEA SSG-34IEC 60364 (all parts)IEC 61226IEC 61000-6-2IAEA SSG-39IEC 62040-31IEC 62855EN 62340IEC 62340IEC 63046IEC 62671EN IEC 61000-6-4EN 62040-3Incorporates the following:Corrigendum, April 2020
