高压开关设备和控制设备 第321部分：用于信息交换的产品数据和特性 目录数据

[中文适用范围]： IEC TR 62271-321:2026适用于所有额定电压高于1千伏交流和1.5千伏直流的高压开关设备和控制设备及其组件，并为其提供涵盖IEC 62271系列产品的参考术语表资料。该术语表为初步成果，旨在促进高压开关设备和控制设备相关组件、装置、设备及电力系统中组装件的数据以数字格式进行交流。此类术语表有助于提升电力系统在生命周期各阶段进行数据交换所需的互操作性。每项属性均具有明确定义的名称和含义；在适用情况下，还定义了数值列表、数据格式及计量单位。本文件定义、数字化并概括了与高压开关设备和控制设备铭牌相关的属性，以及通常由IEC TC 17标准所规定的物理元件在询价、投标和订货等生命周期阶段交换的信息。其意图不包括制造商特有的功能，亦不涉及仅针对评估方法（如计算、试验、规则等）的IEC TC 17标准。 [外文原描述]： IEC TR 62271-321:2026 relates to high-voltage switchgear and controlgear for all rated voltage levels above 1 kV AC and 1,5 kV DC and assemblies thereof and provides materials for the reference dictionary for all products covered by the IEC 62271 series. This dictionary is a preliminary work which can be used to facilitate exchanges in digital format of data related to high-voltage switchgear and controlgear components, devices, equipment, and assemblies of the power systems. Such a dictionary improves the interoperability of the power systems required for these data exchanges along the power system lifetime and over its life cycle. Each property has an unambiguously defined meaning and name, and where relevant, a defined value list, a defined format, and a defined unit. This document defines, digitalizes and then summarizes the properties related to high-voltage switchgear and controlgear nameplates and information usually exchanged during the enquiries, tenders, and orders life phases defined by IEC TC 17 standards of physical elements. The intention is not to cover manufacturer specific features. The intention is not to cover IEC TC 17 standards dealing only with assessment methodology (calculation, tests, rules, etc.).
