标准摘要
[中文适用范围]： 本文件适用于高压/低压预制变电站（以下简称预制变电站），其定义见IEC 62271-202:2014。本文件（除制造商与用户同意的其他选项外）可用于将在一个或多个具有定义额定值和组件布置的预制变电站上进行的型式试验结果，转移至具有不同额定值或不同组件布置的另一个预制变电站。它支持为此目的选择合适的代表性测试对象，以优化型式试验程序，确保持续的符合性评估。本文件利用坚实的技术和物理原理、制造商和用户经验以及双方商定的计算方法，建立关于型式试验结果转移性的实用指导，涵盖各种设计和额定值方面。 [外文原描述]： IEC TR 62271-312:2021(E) refers to high-voltage / low-voltage prefabricated substations (hereinafter prefabricated substations) as specified in IEC 62271-202:2014. This document, among other options as agreed between manufacturer and user, can be used for the transferability of type tests performed on one or more prefabricated substations with a defined set of ratings and arrangement of components to another prefabricated substation with a different set of ratings or different arrangement of components. It supports the selection of appropriate representative test objects for that purpose in order to optimize the type testing procedure for a consistent conformity assessment. This document utilises a combination of sound technical and physical principles, manufacturer and user experience and mutually agreed upon methods of calculation to establish pragmatic guidance for the transferability of type test results, covering various design and rating aspects.
