25、for gas-insulated metal-enclosed switchgear for rated voltages above 52 kV Fluid-filled and extruded insulation cables Fluid-filled and dry-type cable-terminations FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national

26、electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Spe

27、cifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. Intern

28、ational, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The form

29、al decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations fo

30、r international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content 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

31、) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shal

32、l be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liabi

33、lity shall attach to IEC or its directors, 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 (inclu

34、ding legal fees) and expenses arising 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

35、this publication. 9) Attention is drawn 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 62271-209 has been prepared by subcommittee 17

36、C: High-voltage switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and controlgear. This first edition of IEC 62271-209 cancels and replaces the second edition of IEC/TS 60859 and constitutes a technical revision. The changes from IEC/TS 60859 are as follows: the minimu

37、m voltage rating was changed from “72,5 kV” to ”above 52 kV”; the current rating was increased to 3150 A; 4 62271-209 IEC:2007 simplifications and modifications of the dimension tables in Figure 2 and Figure 4 such as diameters for 123 kV to 170 kV have been adopted in order to accommodate larger ca

38、ble cross-sections; new dimensions accept old terminations, new terminations may not meet old GIS standards; the following dimensions have been deleted: l1, l3 as well as note 3 on Figure 4; in Figure 4, new dimensions have been adopted for the voltage range from 245 kV to 300 kV, interchangeability

39、 for 245 kV to 300 kV is not maintained due to reduction in GIS cable termination housing; the lengths l7 and l8 have been modified; changes in the text in relation to minimum functional pressure for insulation pme(Table 1 has been removed); the limit of 170 kV for 3-phase application was deleted (S

40、ubclause 5.2); Figure 5 was deleted. The text of this standard is based on the following documents: FDIS Report on voting 17C/405/FDIS 17C/412/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

41、been 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 unt

42、il the maintenance result 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. 62271-209 IEC:2007 5 HIGH-VOLTAGE SWITCHGEAR AND CONTRO

43、LGEAR Part 209: Cable connections for gas-insulated metal-enclosed switchgear for rated voltages above 52 kV Fluid-filled and extruded insulation cables Fluid-filled and dry-type cable-terminations 1 Scope This standard covers the connection assembly of fluid-filled and extruded cables to gas-insula

44、ted metal enclosed switchgear (GIS), in single- or three-phase arrangements where the cable-terminations are fluid-filled or dry type and there is a separating insulating barrier between the cable insulation and the gas insulation of the switchgear. The purpose of this standard is to establish elect

45、rical and mechanical interchangeability between cable-terminations and the gas-insulated metal-enclosed switchgear and to determine the limits of supply. It complements and amends, if necessary, the relevant IEC standards. For the purpose of this standard the term “switchgear“ is used for “gas-insul

46、ated metal enclosed switchgear“. It does not cover directly immersed cable terminations, as described in CIGRE brochure 89. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For unda
