High-voltage switchgear and controlgear - Part 214: Internal arc classification for AC metal-enclosed pole-mounted switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV 高压开关设备和控制设备.第214部分:额定电压1kV以上和52kV及以下的交流金属封闭杆装开关设备和控制器的内部电弧分类
发布日期: 2024-04-16
IEC 62271-214:2024 EXV包含国际标准及其扩展版本(EXV)。IEC官方标准的扩展版本仅提供英文版本,为用户提供了标准的全面内容。IEC 62271-214:2024 EXV包括参考IEC 62271-1:20 17+AMD1:2021 CSV的内容。 IEC 62271-214:2024规定了额定电压高于1 kV且不超过52 kV且工作频率不超过60 Hz的交流金属封闭柱上安装开关设备和控制设备的内部电弧分类要求。本文件适用于分配了内部电弧分类的三相、两相和单相开式端子设备。外壳可以包括固定的和可移除的部件,并且可以填充有流体(液体或气体)以提供绝缘。这第二版取消并取代了2019年出版的第一版。本版构成技术修订版。与上一版相比,此版本包括以下重大技术变更: a)指标定位更新; b)用于三相试验的试验电路的中性点接地连接; c)与IEC 62271-200第3.0版:2021一致性的一般审查。
IEC 62271-214:2024 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 62271-214:2024 EXV includes the content of the references made to IEC 62271-1:2017+AMD1:2021 CSV.

IEC 62271-214:2024 specifies requirements for internal arc classification of AC metal-enclosed pole-mounted switchgear and controlgear with rated voltages above 1 kV and up to and including 52 kV with service frequencies up to and including 60 Hz. This document is applicable to three-phase, two-phase and single-phase open terminal equipment for which an internal arc classification is assigned. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation. This second edition cancels and replaces the first edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) indicators positioning update;
b) neutral earthing connection of the test circuit for three-phase tests;
c) general review for consistency with IEC 62271-200, Ed.3.0:2021.
