电力电子转换器系统和设备用安全性要求.第1部分:总则

[中文适用范围]： IEC 62477的这一部分适用于电力电子转换器系统（PECS）和设备@其用于电子功率转换和电子功率开关的组件@包括其控制手段@保护@监测和测量@例如以转换电力为主要目的power@ 额定系统电压不超过 1 000 V 交流或 1 500 V 直流 本文件还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。对于不存在产品标准的 PECS@，本标准提供了安全方面的最低要求。 IEC 62477 的这一部分具有符合 IEC 指南 104 的团体安全出版物的地位，适用于太阳能@风@潮汐@波@燃料电池或类似能源的电力电子转换器系统和设备。根据 IEC 指南 104@，技术委员会的职责之一是@在适用的情况下@在准备其产品标准时使用基本安全出版物和/或团体安全出版物。本国际标准： 建立了与 PECS 和设备相关的安全方面的通用术语；制定协调 PECS 内相关部分安全方面的最低要求；为含有 PEC 的产品的 PEC 部分建立最低安全要求的共同基础；规定了在使用和操作期间以及在维修和维护期间减少火灾@电击@热@能源和机械危险@以及@在特别说明的情况下@的要求；规定了降低可插拔和永久连接设备风险的最低要求@无论它是由互连单元还是独立单元组成的系统@都必须按照制造商规定的方式安装@操作和维护设备。本国际标准不包括： 电信设备，但不包括此类设备的电源； IEC 61508 等涵盖的功能安全方面；用于铁路应用和电动汽车的电气设备和系统。 [外文原描述]： IEC 62477-1:2012 applies to Power Electronic Converter Systems (PECS) and equipment, 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 a.c. or 1 500 V d.c. This document may 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 d.c. power supplies. For PECS for which no product standard exists, this standard provides minimum requirements for safety aspects. This part of IEC 62477 has the status of a group safety publication in accordance with IEC Guide 104 for power electronic converter systems and equipment 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. This International Standard: - establishes a common terminology for safety aspects relating to PECS and equipment; - 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 PEC portion of products that contain PEC; - 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; - specifies minimum requirements to reduce risks with respect to pluggable and permanently connected equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the equipment in the manner prescribed by the manufacturer. This International Standard does not cover: - telecommunications apparatus other than power supplies to such apparatus; - functional safety aspects as covered by e.g. IEC 61508; - electrical equipment and systems for railways applications and electric vehicles.
