标准范围

IEC 62271-207:2023适用于-气体绝缘开关设备(GIS)组件-用于符合IEC 62271-203的额定电压高于52 kV的交流电，以及-对于额定电压为100kV及以上的直流电，-用于室内和室外装置，包括其支撑结构，-符合IEC 62271-200的额定电压高于1 kV且不超过52 kV的交流金属封闭开关设备和控制设备组件，安装在地面或地板上，旨在在地震条件下使用，以及-符合IEC 62271-201的额定电压在1 kV以上和52 kV以下的交流固体绝缘封闭式开关设备和控制设备组件，安装在地面或地板上，旨在在地震条件下使用。这第三版取消并取代了2012年出版的第二版。本版构成技术修订版。它还通过合并取消和取代了2013年发布的第一版IEC TS 62271-210。与上一版相比，此版本包括以下重大技术变更:a)将最小额定电压从52 kV修改为1 kV以上，以包括先前在IEC TS 62271-210范围内的中压设备；b)与修订后的IEEE Std 693-2018[1]、附录A和附录P进一步协调资格程序，包括1）将本文件要求的响应谱与IEEE Std 693-2018性能水平谱和IEC TS 62271-210谱相匹配，2)增加了一个分步程序，帮助本文件的用户选择适当的抗震资格级别，将抗震完整性与成本相结合-有效的设计，3）增加分析地震分量组合技术，以及4)参考专门开发的用于测试和分析目的的与IEEE Std 693-2018光谱相匹配的公开可用的加速度图，因为本文件和IEC TS 62271-210光谱在形状上与IEEE Std 693光谱相同。c)测试程序的各种增强；d)增加抗震鉴定报告的最低内容；e)范围扩展至涵盖100 kV及以上的直流GIS。

IEC 62271-207:2023 applies to
- gas-insulated switchgear (GIS) assemblies
- for alternating current of rated voltages above 52 kV complying with IEC 62271-203, and
- for direct current of rated voltages including and above 100 kV,
- for indoor and outdoor installations, including their supporting structures,
- AC metal-enclosed switchgear and controlgear assemblies for rated voltages above 1 kV and up to and including 52 kV complying with IEC 62271-200, ground or floor mounted, intended to be used under seismic conditions, and
- AC solid-insulation enclosed switchgear and controlgear assemblies for rated voltages above 1 kV and up to and including 52 kV complying with IEC 62271-201, ground or floor mounted, intended to be used under seismic conditions.
This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. It also cancels and replaces, through merging, the first edition of IEC TS 62271-210 published in 2013.
This edition includes the following significant technical changes with respect to the previous edition:
a) modification of the minimum voltage rating from 52 kV to above 1 kV in order to include medium voltage equipment previously being within IEC TS 62271-210 scope;
b) further harmonisation of qualification procedures with the revised IEEE Std 693-2018 [1], Annex A and Annex P, including
1) matching this document's required response spectra with IEEE Std 693-2018 performance level spectra and IEC TS 62271-210 spectra,
2) addition of a step-by-step procedure assisting the user of this document to select an appropriate seismic qualification level combining seismic integrity with cost-effective design,
3) addition of analytical earthquake component combination techniques, and
4) reference to publicly available accelerograms specially developed to match the IEEE Std 693-2018 spectra for testing and analysis purposes, since this document and IEC TS 62271-210 spectra are identical in shape with IEEE Std 693 spectra.
c) various enhancements of test procedures;
d) addition of minimum contents for seismic qualification reports;
e) scope extended to cover DC GIS including and above 100 kV.
