29、EQUIPMENT CAPACITORS FOR POWER ELECTRONICS Part 2: Aluminium electrolytic capacitors with non-solid electrolyte FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees
30、). 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 Specifications, Technical Reports, Publicly Available S
31、pecifications (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. International, governmental and non-governmental organizat
32、ions 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 formal decisions or agreements of IEC on technical matte
33、rs 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 for international use and are accepted by IEC National
34、 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) In order to promote international uniformity, IEC
35、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 shall be clearly indicated in the latter. 5) IEC itself
36、does not provide any attestation of conformity. Independent certification bodies provide conformity 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
37、 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 National Committees for any personal injury, property damage or other damage of any nature wh
38、atsoever, 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 publ
39、ications 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. International St
40、andard IEC 61881-2 has been prepared by technical committee 9: Electrical equipment and systems for railways. The text of this standard is based on the following documents: FDIS Report on voting 9/1679/FDIS 9/1707/RVD Full information on the voting for the approval of this standard can be found in t
41、he report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 6 61881-2 IEC:2012 A list of all parts of IEC 61881 series, under the general title Railway applications Rolling stock equipment Capacitors for power electronics, ca
42、n be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until 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
43、 withdrawn, replaced by a revised edition, or amended. 61881-2 IEC:2012 7 RAILWAY APPLICATIONS ROLLING STOCK EQUIPMENT CAPACITORS FOR POWER ELECTRONICS Part 2: Aluminium electrolytic capacitors with non-solid electrolyte 1 Scope This part of IEC 61881 applies to d.c. aluminium electrolytic capacito
