标准摘要
[中文适用范围]： 本部分 IEC 62271 适用于设计用于室内或室外安装、在频率为 50 Hz 和 60 Hz 的系统上运行、电压高于 1000 V 的交流断路器。注：虽然本技术报告主要涉及断路器，但某些条款（例如第 5 条）适用于开关设备和控制设备。本技术报告面向制定和应用高压断路器规范的用户、咨询机构和工业工程师，断路器开发工程师，测试站工程师以及参与标准化工作的工程师。旨在提供有关标准中事实和数据的基础信息，并为高压断路器的规范制定提供依据。因此，其范围涵盖高压断路器相关的 IEC 62271-100 和 IEC 62271-1 及相关标准和技术报告的说明、解释和应用。带有故意非同时动作的断路器的规则由 IEC 62271-302 涵盖。本技术报告不适用于用于电气牵引设备动力单元的断路器；这些由 IEC 60077 系列涵盖。安装在发电机和升压变压器之间的发电机断路器不在本技术报告的范围内。本技术报告不适用于带有机械脱扣装置或无法使其失效的自动脱扣断路器。隔离断路器由 IEC 62271-108 涵盖。在线路串联电容器及其保护设备旁的旁路开关不在本技术报告的范围内；这些由 IEC 62271-109 和 IEC 60143-2 涵盖。此外，特殊应用（其中包括并联切换、延迟电流过零点）在本文档的附录中处理。 [外文原描述]： IEC TR 62271-306:2012+A1:2018 is applicable to a.c. circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. This technical report addresses utility, consultant and industrial engineers who specify and apply high-voltage circuit-breakers, circuit-breaker development engineers, engineers in testing stations, and engineers who participate in standardization. It is intended to provide background information concerning the facts and figures in the standards and provide a basis for specification for high-voltage circuit-breakers. Thus, its scope will cover the explanation, interpretation and application of IEC 62271-100 and IEC 62271-1 as well as related standards and technical reports with respect to high-voltage circuit-breakers. This consolidated version consists of the first edition (2012) and its amendment 1 (2018). Therefore, no need to order amendment in addition to this publication.
