不间断电源(UPS).第1部分:UPS用一般要求和安全要求

[中文适用范围]： IEC 62040 的这一部分适用于直流链路中带有电能存储设备的不间断电源系统 (UPS)。它与 IEC 60950-1 一起使用，在本标准中称为“RD”（参考文件）。注意 UPS 应用通常使用化学电池作为储能设备。替代设备可能适用，因此，如果本标准文本中出现“电池”，则可将其理解为“储能设备”。当用“适用项目/RD 的定义或规定”这句话引用某条款时，该短语旨在表示 IEC 60950-1 中该条款中的定义或规定适用，但明显不适用于不间断电源系统的定义或规定除外。除 IEC 60950-1 中的要求外，还适用国家要求，这些要求可在 RD 相关条款的注释中找到。本标准涵盖的 UPS 的主要功能是确保交流电源的连续性。 UPS 还可将电源保持在规定的特性范围内，从而改善电源质量。本标准适用于移动式、静止式、固定式或内置式 UPS，用于低压配电系统，并计划安装在任何操作员可触及的区域或视情况而定限制访问位置。它规定了确保可能接触设备的操作人员和外行人员安全的要求，以及（如有特别说明）维修人员的安全。本标准旨在确保已安装的 UPS 的安全，无论是作为单个 UPS 单元还是作为互连的 UPS 单元系统，只要按照制造商规定的方式安装、操作和维护 UPS。本标准不涵盖基于旋转机器的 UPS。电磁兼容性 (EMC) 要求和定义在 IEC 62040-2 中给出。 [外文原描述]： IEC 62040-1:2008 applies to uninterruptible power systems (UPS) with an electrical energy storage device in the d.c. link. It is used with IEC 60950-1, which is referred to in this standard as "RD" (reference document). It is applicable to UPS which are movable, stationary, fixed or for building-in, for use in low-voltage distribution systems and intended to be installed in any operator accessible area or in restricted access locations as applicable. It specifies requirements to ensure safety for the operator and layman who may come into contact with the equipment and, where specifically stated, for the service person. It cancels and replaces the first edition of IEC 62040-1-1, published in 2004 and IEC 62040-1-2, published in 2004 and constitutes a technical revision. This standard merges all requirements of previous IEC 62040-1-1 and IEC 62040-1-2, with the addition of the following: - update of normative references including IEC 60950-1 as Reference Document (RD); - harmonization and alignment with current world recognized best practices; - enhancement of backfeed protection, definition of ground-fault, revision of temperature rise tables and of hydrogen concentration in battery compartments. The contents of the corrigendum of September 2008 have been included in this copy.
