标准摘要
[中文适用范围]: 本国际标准适用于电动汽车模式2充电的线缆控制和保护装置(IC-CPDs),以下简称“IC-CPD”,包括控制和安全功能。本文件适用于同时执行剩余电流检测、将该电流值与剩余操作值进行比较以及在剩余电流超过该值时断开受保护电路的便携式设备。根据本文件的IC-CPD:• 根据IEC 61851-1:2017附录A提供控制导频功能;• 检查供电条件并在特定条件下防止在供电故障时充电;• 可以具有开关保护导体。考虑了与额定频率不同的剩余电流、直流剩余电流和特定环境情况。本文件适用于执行IEC 61851-1中电动汽车模式2充电所需的安全和控制功能的IC-CPDs。本文件适用于不超过250V的单相电路或不超过480V的多相电路的IC-CPDs,其最大额定电流为32A。本文件适用于仅在交流电路中使用的IC-CPDs,额定频率优选值为50Hz、60Hz或50/60Hz。根据本文件的IC-CPDs不适用于双向或反向功率传输,将能量反馈回电力分配系统。本文件适用于额定剩余操作电流不超过30mA的IC-CPDs,旨在为IC-CPD下游电路提供额外保护,因为不能保证上游安装配备了额定I∆n≤30mA的RCD。IC-CPD由以下部分组成:• 用于连接到固定安装中的插座插头;• 一个或多个包含控制和保护特性的子组件;• 插头和子组件之间的电缆(可选);• 子组件和车辆连接器之间的电缆(可选);• 用于连接到电动汽车的车辆连接器。对于家用和类似用途的插头,适用各自国家标准的特定要求以及产品上市国家国家委员会定义的特定要求。如果没有国家要求,则适用IEC 60884-1。对于工业插头,适用IEC 60309-2。对于特定应用和区域,可以使用不可互换的工业插头。在这种情况下,适用IEC 60309-1。IC-CPD中的插头、连接器和电缆根据相关产品标准进行测试。IC-CPD的开关触点不提供隔离功能,因为可以通过断开插头来确保隔离。IC-CPD不被视为用于固定安装的保护装置。 [外文原描述]: IEC 62752:2024 This International Standard applies to in-cable control and protection devices (IC-CPDs) for mode 2 charging of electric road vehicles, hereafter referred to as "IC-CPD", including control and safety functions. This document applies to portable devices performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value. This second edition cancels and replaces the first edition published in 2016, and Amendment 1:2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Subclause 8.3.1 revised to add requirements for a mandatory control device that detects the temperature of the current carrying parts in the household plug; - Test requirements added in a new Subclause 9.36 for the temperature control device; - Harmonization of EMC requirements with new edition of IEC 61543 and IEC 61851-21-2; - General improvement of test and requirements.
