标准摘要
[中文适用范围]: 本部分IEC 62271适用于: - 气体绝缘开关设备(GIS)组件 • 额定电压高于52 kV的交流电,符合IEC 62271-203; • 额定电压包括和高于100 kV的直流电; • 室内和室外安装,包括其支撑结构; - 额定电压高于1 kV且包括和高达52 kV的交流金属封闭开关设备和控制设备组件,符合IEC 62271-200,地面或地板安装,用于地震条件下; - 额定电压高于1 kV且包括和高达52 kV的交流固体绝缘封闭开关设备和控制设备组件,符合IEC 62271-201,地面或地板安装,用于地震条件下。 开关设备和控制设备组件的地震鉴定考虑了典型开关设备和控制设备组件的测试与分析方法的结合。考虑了直接安装的辅助和控制设备与开关设备组件之间的相互影响。 地震鉴定理念包括地震鉴定等级的选择(第4章)、通过测试(第5章)和通过测试与分析结合(第6章)的鉴定方法、验收标准(第7章)和地震鉴定文档(第8章)。附录B提供了关于提高开关设备和控制设备组件地震适应性的建议。附录C包含了地震鉴定过程的流程图。 开关设备和控制设备组件的地震鉴定由制造商在需要时进行。 [外文原描述]: 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.
