新的！IEC 62271-110:2017作为IEC 62271-110:2017 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62271-110:2017适用于为室内或室外安装而设计的交流开关设备，在电压高于1？000 V，应用于感应电流开关。它适用于用于切换高？电压电机电流和并联电抗器电流，以及IEC 62271-106涵盖的用于切换高压电机电流的高压接触器。第四版取消并取代了2012年出版的第三版，构成技术修订。与上一版相比，此版本包括以下重大技术变更:-现在涵盖了所有开关设备，而不仅仅是断路器；-有限数量的T10试验不再涵盖52 kV以下的并联电抗器切换试验；-增加了无复燃电弧时间窗的评估和报告。

NEW!IEC 62271-110:2017 is available as IEC 62271-110:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62271-110:2017 is applicable to AC switching devices designed for indoor or outdoor installation, for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1？000 V and applied for inductive current switching. It is applicable to switching devices (including circuit-breakers in accordance with IEC 62271-100) that are used to switch high？voltage motor currents and shunt reactor currents and also to high-voltage contactors used to switch high-voltage motor currents as covered by IEC 62271-106. This fourth edition cancels and replaces the third edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- all switching devices are now covered, not only circuit-breakers;
- a limited number of T10 tests no longer covers shunt-reactor switching tests below 52 kV;
- evaluation and reporting of a re-ignition-free arcing time window has been added.
