[中文适用范围]： 本部分IEC 60204适用于电气、电子、可编程电子设备和系统在起重机械及相关设备中的应用，包括一组以协调方式共同工作的起重机械。 注1：在本文件中，术语“电气”包括电气和电子事项（即“电气设备”指电气、电子和可编程电子设备）。 注2：在本文件的上下文中，术语“人”指任何个人，包括由用户或用户代理人指派并指导使用和照顾相关起重机械的人员。 本文件涵盖的设备始于起重机械电气设备的电源连接点（起重机电源开关），包括位于起重机械外部的电源和控制系统馈线，例如柔性电缆、导线或导电条（见图3）。 注3：有关建筑物电气安装的要求，请参见IEC 60364。起重机械电气设备的电气安装要求在IEC 60364中给出。 本文件适用于线路间电压不超过1000V交流或1500V直流且额定频率不超过200Hz的设备或设备部件。 注4：对于更高电压，请参见IEC 60204-11。起重机械电气设备在更高电压下运行的特殊要求可在IEC 60204-11中找到。 本文件不涵盖为保护人员免受电气危害以外的其他危害所需或由其他标准或法规规定的所有要求（例如防护、联锁或控制）。每种类型的起重机械都有独特的要求，以提供足够的安全性。本文件不涵盖噪声风险。 起重机械的电气设备可能有额外的特殊要求，包括： - 用于露天（即建筑物或其他防护结构外部）的设备； - 处理或运输潜在爆炸性材料（例如油漆或锯末）的设备； - 用于潜在爆炸性和/或易燃环境的设备； - 运输或移动某些材料时有特殊风险的设备； - 用于矿山的设备。 在本文件中，起重机械包括各类起重机、各类卷扬机和存储及检索机械。包括以下产品组： - 桥式起重机； - 移动式起重机； - 塔式起重机； - 旋转变幅起重机； - 门式起重机； - 海上起重机； - 浮式起重机； - 各类卷扬机； - 提升机和附件； - 装载起重机； - 缆索起重机； - 负载保持装置； - 存储及检索机械； - 单轨提升机； - 跨运车； - 橡胶轮胎门式起重机（RTG）。 注5：不同类型起重机的定义可在ISO 4306-1中找到。 本文件不涵盖电气设备的单个项目，除非涉及它们的选择和使用及其安装。 [外文原描述]： IEC 60204-32:2023 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60204-32:2023 edition 3.0 and the previous IEC 60204-32:2023:2008 edition 2.0. Furthermore, comments from IEC TC 44 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 60204-32:2023 applies to electrical, electronic, programmable electronic equipment and systems to hoisting machines and related equipment, including a group of hoisting machines working together in a co-ordinated manner. The equipment covered by this document commences at the point of connection of the supply to the electrical equipment of the hoisting machine (crane-supply-switch) and includes systems for power supply and control feeders situated outside of the hoisting machine, for example, flexible cables or conductor wires or conductor bars. This document is applicable to equipment or parts of equipment not exceeding 1 000 V AC or 1 500 V DC between lines and with nominal frequencies not exceeding 200 Hz. This document does not cover all the requirements (for example guarding, interlocking, or control) that are needed or required by other standards or regulations in order to protect persons from hazards other than electrical hazards. Each type of hoisting machine has unique requirements to be accommodated to provide adequate safety. This document does not cover noise risks. Additional and special requirements can apply to the electrical equipment of hoisting machines including those that – handle or transport potentially explosive material (e.g. paint or sawdust); – are intended for use in potentially explosive and/or flammable atmospheres; – have special risks when transporting or moving certain materials; – are intended for use in mines. For the purposes of this document, hoisting machines include cranes of all types, winches of all types and storage and retrieval machines. The following product groups are included: – overhead travelling cranes; – mobile cranes; – tower cranes; – slewing luffing cranes; – gantry cranes; – offshore cranes; – floating cranes; – winches of all types; – hoists and accessories; – loader cranes; – cable cranes; – load holding devices; – storage and retrieval machines; – monorail hoists; – straddle carriers; – rubber tyred gantry cranes (RTGs). This document does not cover individual items of electrical equipment other than their selection for use and their erection. IEC 60204-32:2023 cancels and replaces the second edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment to the IEC 60204-1 sixth edition (2016) especially for: – requirements for earthing and bonding; – requirements for circuit protection; – consideration of use of Power Drive Systems; – protective bonding requirements and terminology; – requirements pertaining to safe torque off for PDS, emergency stop, and control circuit protection; – symbols for actuators of control devices; b) reference for high voltage electrical equipment; c) cableless control system requirements; d) EMC requirements; e) technical documentation requirements; f) general updating to current special national conditions, normative standards, and bibliographical references.
