标准摘要
[中文适用范围]： 本部分IEC 62271规定了交流电压高达52 kV的高压变电站主要电气功能单元组装的适用条件、额定特性、一般结构要求和试验方法，这些单元已正确互连，适用于高/低侧交流电压高达52 kV且服务频率为50 Hz或60 Hz的情况。CEADS通过电缆连接到高压网络，适用于受限访问的室内和室外应用。本文件中定义的CEADS设计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/高压或高压/低压变换；以及以下部分或全部功能：对高压电路的操作进行开关和控制；对低压电路的操作进行开关和控制；保护电力变压器功能单元。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。 [外文原描述]： 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.
