标准摘要
[中文适用范围]: 本部分IEC 62271规定了高压/低压配电高压变电站主要电气功能单元组件的使用条件、额定特性、一般结构要求和试验方法,这些组件经过适当互连,适用于高压侧额定工作电压超过1kV且包括52kV的交流系统,工作频率为50Hz或60Hz。该组件通过电缆连接到网络,并设计用于安装在室内或室外的封闭电气操作区域。CEADS通过电缆连接到高压网络,适用于限制访问的室内和室外应用。 本文件定义的CEADS设计和测试为具有单一序列号和一套文档的单一产品。 CEADS的功能包括: - 高压电路的开关和控制操作; - 高压/低压变压器功能单元的保护; - 高压/低压变换; - 低压馈线的操作和保护的开关和控制。 然而,本文件的相关规定也适用于不包含所有这些功能的设计(例如,仅包含高压/低压变换和低压馈线操作和保护的设备,或不包含高压电路操作开关和控制的设备)。 主要功能集成在以下功能单元中: - 高压功能单元; - 电力变压器功能单元; - 低压功能单元。 注:就本文件而言,自保护变压器不被视为CEADS,而是被视为功能单元,根据其自己的产品标准IEC 60076-13:2006设计和类型测试。 [外文原描述]: IEC 62271-212:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62271-212;2022 specifies the service conditions, rated characteristics, general structural requirements and test methods of the assemblies of the main electrical functional units of a high-voltage transformer substation, duly interconnected, for AC voltages up to and including 52 kV on the high-voltage side and service frequency 50 Hz or 60 Hz. The CEADS is cable‑connected to the high-voltage network for indoor and outdoor applications of restricted access. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - clause numbering aligned with IEC 62271-1:2017, - rewording of title and scope of the document, - implement changes on internal arc definition and testing following the evolution of prefabricated substation concept according to IEC 62271-202, - general review of main test procedures such as temperature rise or dielectric test on interconnections, considering control equipment, communication, smart grid devices and integration of components, - general review of installation, operation, safety and maintenance requirements.
