不间断电源系统(UPS).第1部分:安全要求

[中文适用范围]： IEC 62040 的本部分适用于低压配电系统中使用的移动式、固定式、固定式或内置式 UPS，并且拟安装在普通人可进入的区域或适用的限制进入区域，并且提供固定频率交流输出电压，端口电压不超过 1000 V AC 或 1500 V DC，并包含储能装置。它适用于可插拔和永久连接的 UPS，无论是由互连单元组成的系统还是由独立单元组成的系统，均须按照制造商规定的方式安装、操作和维护 UPS。注 1：典型的 UPS 配置，包括电压和/或频率转换器以及其他拓扑，在 UPS 测试和性能产品标准 IEC 62040-3 中进行了描述。注 2：UPS 通常通过直流链路连接到其储能设备。整个标准中都使用化学电池作为能量存储设备的示例。存在替代设备，因此，当本文档的文本中出现“电池”时，这应被理解为“能量存储设备”。本文件规定了确保接触 UPS 的普通人员以及技术人员（如有特别说明）安全的要求。目的是减少使用和操作期间以及（特别说明）维修和维护期间发生火灾、触电、热、能量和机械危险的风险。该产品标准与电力电子转换器系统团体安全出版物 IEC 62477-1:2012 的适用部分相协调，并包含与 UPS 相关的附加要求。本文档不包括： 具有直流输出的 UPS；用于在移动平台上运行的系统，包括但不限于飞机、船舶和机动车辆；其特定产品标准涵盖的外部交流或直流输入和输出配电板；独立静态传输系统（ [外文原描述]： 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.
