10、nization for standardization comprising all national 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,
11、 IEC publishes International Standards, Technical Specifications, 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
12、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 the International Organization for Standardization (ISO) in accordance with conditions determined by
13、 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 subjects since each technical committee has representation from all interested IEC National Committees. 3)
14、 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 content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are
15、 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 possible in their national and regional publications. Any divergence between any IEC Publication and th
16、e corresponding national or regional publication shall 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 hav
17、e the latest edition of this publication. 7) No liability 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 whatso
18、ever, whether direct or indirect, or for costs (including 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 publicat
19、ions is indispensable for the correct application of 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. The main task of IEC
20、 technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 62271-3
21、01, which is a technical report, has been prepared by subcommittee 17A: High-voltage switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear. This second edition cancels and replaces the first edition published in 2004 and constitutes a technical revision. The main chan
22、ges with respect to the previous edition are the addition of Clause 2, Terms and definitions, as well as Figures 2 through 7.

However,
27、 its application to other equipment is not excluded. No coordination between dimensions and the rated normal current can be given. 2 Terms and definitions For the purposes of this document, the following terms and definition apply. 2.1 high-voltage (HV) terminal conductive part of switchgear and con

The
31、dimensions are as follows: hole diameters: 14 mm, 16 mm, 17 mm, 18 mm 19 mm and 22 mm; distance between holes: 40 mm, 45 mm, 50 mm and 60 mm (centre-to-centre). NOTE A hole diameter of 14,3 mm and distance between holes of 44,5 mm exist in certain countries. Any possible combination of these dimensi
32、ons is permitted. The distance between holes should be applied to two adjacent holes, both along the abscissa or ordinate. Typical examples of hole arrangements are given in Figures 2 through 7.
