标准摘要
[中文适用范围]： 本部分 IEC 62271 是一项技术规范，适用于设计用于室内或室外安装、在1000V以上系统中运行的交流断路器，频率为50Hz和60Hz。本文件提供了这种类型断路器的附加额定值和类型测试，旨在与IEC 62271-100:2021一起使用。有意非同时极操作可以通过机械或电气手段实现，这两种方法都在本文件的范围内。 [外文原描述]： IEC TS 62271-319:2024 is applicable to alternating current circuit-breakers with intentional non-simultaneous pole operation designed for indoor or outdoor installations and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. This document provides additional ratings and type tests to be conducted for this type of circuit-breaker and is intended to be used in conjunction with IEC 62271‑100:2021. Intentional non-simultaneous pole operation can be implemented by mechanical or electrical means and both methods are within the scope of this document.
