标准范围

IEC 62477-1:20 22适用于电力电子转换器系统（PECS）、任何指定附件及其用于电子电力转换和电子电力开关的组件，包括其控制、保护、监控和测量装置，例如以转换电力为主要目的，额定系统电压不超过1 000 V AC或1 500 V DC。本文件也适用于出于无线电通信目的故意发射或接收无线电波的PEC。本文件也可用作产品委员会制定以下产品标准的参考标准:可调速电力驱动系统（PDS）；独立不间断电源系统（UPS）；低压稳定直流电源；双向功率转换器。对于不存在产品标准的胸肌及其指定附件，本文件提供了安全方面的最低要求。根据IEC指南104，本文件具有用于太阳能、风能、潮汐能、波浪能、燃料电池或类似能源的电力电子转换器系统的团体安全出版物的地位。根据IEC指南104，技术委员会的职责之一是在适用的情况下，在制定其产品标准时利用基本安全出版物和/或团体安全出版物。产品委员会使用本集团安全性出版物的指南见附录S。本文件为与胸肌相关的安全方面建立通用术语，为PECS内相关部件的安全方面的协调建立最低要求，为含有PECS的产品的PECS部分的最低安全要求建立共同基础，规定在使用和操作期间，以及在特别规定的情况下，在服务和维护期间，降低火灾、电击、热、能量和机械危害风险的要求，以及规定了降低设计为可插拔和永久连接设备的PEC风险的最低要求，无论其由互连单元系统还是独立单元组成，但须按照制造商规定的方式安装、操作和维护PEC。本文档不涵盖电信设备，例如，IEC 61508（所有部分）涵盖的功能安全方面，以及铁路应用和电动车辆用电气设备和系统。与上一版相比，此版本包括以下重大技术变更:a)发射或接收添加在示波器中的无线电波的PECS；b)将DVC的概念简化为包括电压-时区；c)根据IEC 61140改进概念“保护”与“绝缘”的一致性；d)更新了接触电流的限制，增加了PE导体电流的限制；e)薄片胶带材料返工并增加测试；f)增加多层印刷线路板的内层；g)更新机械危害；h)更新了外壳要求；i)更新了布线和连接要求；j)更新了聚合物外壳要求；k)添加组件的要求；l)增加了几项测试（例如UV、工作电压、SPD、预处理）；m)更新信息和标记要求；n)对所加符号对比度的要求；o)更新了若干附件。

IEC 62477-1:2022 applies to power electronic converter systems (PECS), any specified accessories, and their components for electronic power conversion and electronic power switching, including the means for their control, protection, monitoring and measurement, such as with the main purpose of converting electric power, with rated system voltages not exceeding 1 000 V AC or 1 500 V DC.
This document also applies to PECS which intentionally emit or receive radio waves for the purpose of radio communication.
This document can also be used as a reference standard for product committees producing product standards for:

• adjustable speed electric power drive systems (PDS);
• standalone uninterruptible power systems (UPS);
• low voltage stabilized DC power supplies;
• bidirectional power converters.

For PECS and their specified accessories for which no product standard exists, this document provides minimum requirements for safety aspects.
This document has the status of a group safety publication in accordance with IEC Guide 104 for power electronic converter systems for solar, wind, tidal, wave, fuel cell or similar energy sources.
According to IEC Guide 104, one of the responsibilities of technical committees is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of their product standards.
Guidance for use of this group safety publication for product committees is given in Annex S.
This document

• establishes a common terminology for safety aspects relating to PECS,
• establishes minimum requirements for the coordination of safety aspects of interrelated parts within a PECS,
• establishes a common basis for minimum safety requirements for the PECS portion of products that contain PECS,
• specifies requirements to reduce risks of fire, electric shock, thermal, energy and mechanical hazards, during use and operation and, where specifically stated, during service and maintenance, and
• specifies minimum requirements to reduce risks with respect to PECS designed as pluggable and permanently connected equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the PECS in the manner prescribed by the manufacturer.

This document does not cover

• telecommunications apparatus other than power supplies to such apparatus,
• functional safety aspects as covered by, for example, IEC 61508 (all parts), and
• electrical equipment and systems for railways applications and electric vehicles.

This edition includes the following significant technical changes with respect to the previous edition:
