不间断电源系统（UPS）.第1部分:安全要求

[中文适用范围]： 本部分 IEC 62040 适用于低电压配电系统中使用的移动式、固定式或内置式不间断电源(UPS)，这些UPS设计用于普通人员可接触的区域或受限访问区域，提供固定频率的交流输出电压，端口电压不超过1000V AC或1500V DC，并包含能量存储设备。它适用于插接式和永久连接的UPS，无论是由互连单元组成的系统还是独立单元，只要按照制造商规定的方式安装、操作和维护即可。 注1：典型的UPS配置，包括电压和/或频率转换器及其他拓扑结构，在IEC 62040-3（UPS的测试和性能产品标准）中有描述。 注2：UPS通常通过直流链路连接到其能量存储设备。本标准中化学电池作为能量存储设备的示例。存在替代设备，因此，在本文件中出现“电池”一词时，应理解为“能量存储设备”。 本文件规定了确保普通人员接触UPS时的安全要求，并在特定情况下适用于熟练人员。目的是减少在使用和操作过程中以及特定情况下在服务和维护过程中的火灾、电击、热、能量和机械危害的风险。 本产品标准与适用于电力电子转换器系统的组安全出版物IEC 62477-1:2012的相关部分协调一致，并包含与UPS相关的附加要求。 本文件不包括： - 具有直流输出的UPS； - 用于移动平台的系统，包括但不限于飞机、船舶和机动车辆； - 由特定产品标准涵盖的外部交流或直流输入和输出配电板； - 由IEC 62310-1涵盖的独立静态转换系统（STS）； - 输出电压直接来自旋转机器的系统； - 除用于此类设备的UPS之外的电信设备； - 由IEC 61508（所有部分）涵盖的功能安全方面。 注3：即使本文件未涵盖上述应用，通常也将其作为此类应用的指南。 注4：专用UPS应用通常受其他地方的附加要求约束，例如用于医疗应用的UPS。 [外文原描述]： IEC 62040-1:2017 EXV includes the provisions of the general rules dealt with in IEC 62477-1:2012 . The Extended version is not an official IEC Standard. Only the current versions of the related standards are to be considered the official documents. The Extended version is available in English only. IEC 62040-1:2017 applies to movable, stationary, fixed or built-in UPS for use in low-voltage distribution systems and that are intended to be installed in an area accessible by an ordinary person or in a restricted access area as applicable, that deliver fixed frequency AC output voltage with port voltages not exceeding 1 000 V AC or 1 500 V DC and that include an energy storage device. It applies to pluggable and to permanently connected UPS, whether consisting of a system of interconnected units or of independent units, subject to installing, operating and maintaining the UPS in the manner prescribed by the manufacturer. This document specifies requirements to ensure safety for the ordinary person who comes into contact with the UPS and, where specifically stated, for the skilled person. The objective is to reduce risks of fire, electric shock, thermal, energy and mechanical hazards during use and operation and, where specifically stated, during service and maintenance. This product standard is harmonized with the applicable parts of group safety publication IEC 62477-1:2012 for power electronic converter systems and contains additional requirements relevant to UPS. This edition includes the following significant technical change with respect to the previous edition: the reference document has been changed from IEC 60950-1:2005 (safety for IT equipment) to IEC 62477-1 (group safety standard for power electronic converters). The contents of the corrigendum of October 2019 have been included in this copy.
