标准范围

IEC TR 62271-312:2021（E）是指IEC 62271-202:2014中规定的高压/低压预制变电站（以下简称预制变电站）。除制造商和用户之间商定的其他选项外，本文件可用于将在一个或多个具有定义的额定值和组件布置的预制变电站上执行的型式试验转移到具有不同额定值或组件布置的另一个预制变电站。它支持为此目的选择适当的代表性测试对象，以便优化型式测试程序，以实现一致的合格评定。本文件结合了合理的技术和物理原理、制造商和用户经验以及双方同意的计算方法，为型式试验结果的可转移性建立了实用的指南，涵盖了各个设计和评级方面。

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.
