标准摘要
[中文适用范围]： IEC 62271-100的这部分适用于设计用于室内或室外安装、在频率为50 Hz和/或60 Hz的系统中运行、电压高于1 000 V的三相交流断路器。本文件仅包含做分断试验的直接试验方法。关于合成试验方法，请参考IEC 62271-101。 直接试验方法是指使用一个电源在合闸和分闸试验期间提供电压和电流。本文件不适用于：具有依赖手动操作合闸机构的断路器；用于电动牵引设备动力单元的断路器（由IEC 60077（所有部分）[1]涵盖）；安装在发电机和升压变压器之间的发电机断路器（由IEC 62271-37-013 [2]涵盖）；具有在试验期间无法失效的脱扣装置的自跳闸断路器（自动重合断路器的试验由IEC 62271-111 [3]涵盖）。证明在异常条件下性能的试验（本文档未描述的）需由制造商和用户协商确定。此类异常条件例如电压高于断路器额定电压、长线路或电缆突然失去负载等情况。 [外文原描述]： IEC 62271-100:2021 is applicable to three-phase AC circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and/or 60 Hz on systems having voltages above 1 000 V. This document includes only direct testing methods for making-breaking tests. For synthetic testing methods refer to IEC 62271-101. This third edition cancels and replaces the second edition published in 2008, Amendment 1:2012 and Amendment 2:2017. This edition constitutes a technical revision. The main changes with respect to the previous edition are listed below: – the document has been updated to IEC 62271-1:2017; – Amendments 1 and 2 have been included; – the definitions have been updated, terms not used have been removed; – Subclauses 7.102 through 7.108 have been restructured. The contents of the corrigendum of December 2021, July 2022 and January 2024 have been included in this copy.
