31、 and energy 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 standardiz

32、ation 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 preparation is

33、 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 the I

34、nternational 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 subjects si

35、nce 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 conten

36、t 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 possible

37、 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment

38、 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 liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC Na

39、tional 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 out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention

40、 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 drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC sh

41、all not be held responsible for identifying any or all such patent rights. International Standard IEC 61800-5-1 has been prepared by subcommittee 22G: Semi-conductor power converters for adjustable speed electric drive systems, of IEC technical committee 22: Power electronic systems and equipment. T

42、his second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. The major areas of change in this edition are the following: a) addition of alphabetical Table 1 in Clause 3; b) addition of Table 2 in 4.1 for relevance to PDS/CDM/BDM; c) addition of T

43、able 4 summary of decisive voltage class requirements; d) expansion of subclause on protective bonding (4.3.5.3); SANS 61800-5-1:2008This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS . 6 61800-5-1 IEC:2007 e) clarification of distinction between

44、 touch current and protective conductor current; f) revision of section on insulation (now 4.3.6) to include solid insulation; g) addition of overvoltage categoruies I and II to HV insulation voltage; h) revision of section on Solid insulation (now 4.3.6.8) i) addition of high-frequency insulation r

45、equirements (4.3.6.9, Annex E); j) addition of requirements for liquid-cooled PDS (4.4.5); k) addition of climatic and vibration tests (5.2.6); l) clarification of voltage test procedure to avoid over-stress of basic insulation (5.2.3.2.3); m) revision of short-circuit test requirement for large, hi

46、gh-voltage and one-off PDS (now 5.2.3.6); n) addition of informative Annex B for overvoltage category reduction. The text of this standard is based on the following documents: FDIS Report on voting 22G/178/FDIS 22G/181/RVD Full information on the voting for the approval of this standard can be found

47、 in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 61800 series, published under the general title Adjustable speed electrical power drive systems, can be found on the IEC website.

48、 Terms in italics in the text are defined in Clause 3. The committee has decided that the contents of this publication will remain unchanged until 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, th

49、e publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.
