25、ges above 52 kV FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standa
26、rdization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparatio
27、n is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
28、the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjec
29、ts since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical c
30、ontent of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent pos
31、sible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide confor
32、mity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its direct
33、ors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising
34、out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is draw
35、n to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62271-207 has been prepared by subcommittee 17C: High-voltage switchgear and control
36、gear assemblies, of IEC technical committee 17: Switchgear and controlgear. This second edition of IEC 62271-207 cancels and replaces the first edition published in 2007. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previo
37、us edition: modification of the minimum voltage rating from 72,5 kV to above 52 kV; harmonisation of qualification procedures for GIS with IEEE 693:2005 Annex A and P by modifying the response spectra; modification of the test procedures; addition of criteria of allowed stresses; 4 62271-207 IEC:201
38、2 addition of dynamic analysis CQC. The text of this standard is based on the following documents: FDIS Report on voting 17C/542/FDIS 17C/549/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has b
39、een drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 62271 series, under the general title High-voltage switchgear and controlgear, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged unti
40、l the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this public
41、ation indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 62271-207 IEC:2012 5 HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR Part 207: Seismic qualification for gas-insulated
42、switchgear assemblies for rated voltages above 52 kV 1 Scope This part of IEC 62271 applies to gas-insulated switchgear assemblies for alternating current of rated voltages above 52 kV for indoor and outdoor installations, including their supporting structure. For switchgear devices, e.g. live tank
43、circuit breakers, IEC/TR 62271-300 is applicable. Guidance on interactions between the supporting structure and the soil / foundations is provided in Annex B. The seismic qualification of the switchgear assemblies takes into account testing of typical switchgear assemblies combined with methods of a
44、nalysis. Mutual interaction between directly mounted auxiliary and control equipment and switchgear assemblies are covered. The seismic qualification of switchgear assemblies is only performed upon request. 2 Normative references The following documents, in whole or in part, are normatively referenc
45、ed in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60068-2-47, Environmental testing Part 2-47: Tests Mounting of specimens

It may be proofed by test or by a combination of test and analysis. No failure on the enclosure and the main circ
49、uits as well as on the control and auxiliary circuit, including the relevant supporting structures, shall occur. For ductile material, minor permanent deformations are acceptable provided that they do not impair the functionality of the equipment. The equipment shall properly operate after the seismic event as defined in 7.2 and 7.3. 4.2 Qualification levels The qualification has to be done on one
