29、OTECHNICAL COMMISSION _ SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND COMBINATIONS THEREOF Part 2-10: Particular requirements and tests for separating transformers with high insulation level and separating transformers with output voltages exceeding 1 000 V FOREWORD 1) The International E
30、lectrotechnical 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 standardization in the electrical and electronic fiel
31、ds. 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 entrusted to technical committees; any IEC
32、 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 International Organization for Standardizat
33、ion (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 since each technical committee has represent
34、ation 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 content of IEC Publications is accurate, IEC can
35、not 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 in their national and regional publicatio
36、ns. 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 conformity assessment services and, in some areas, ac
37、cess 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 directors, employees, servants or agents including in
38、dividual 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 out of the publication, use of, or reliance upo
39、n, 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 drawn to the possibility that some of the elements
40、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 61558-2-10 has been prepared by IEC technical committee 96: Transformers, reactors, power supply units, and combinations thereof. T
41、his first edition cancels and replaces Chapter ll Section Three of IEC 60989 published in 1991. It constitutes a technical revision. The main changes consist of a) updating this part in accordance with IEC 61558-1:2005, and b) adding power supply units to the scope. 4 IEC 61558-2-10:2014 IEC 2014 Th
42、e text of this standard is based on the following documents: FDIS Report on voting 96/407/FDIS 96/408/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 been drafted in accordance with the ISO/I
43、EC Directives, Part 2. This Part 2-10 is intended to be used in conjunction with the latest edition of IEC 61558-1 and its amendments. It is based on the second edition (2005) of that standard and its Amendement 1 (2009). This Part 2-10 supplements or modifies the corresponding clauses in IEC 61558-
44、1, so as to convert that publication into the IEC standard: Particular requirements and tests for separating transformers with high insulation level and separating transformers with output voltages exceeding 1 000 V. A list of all parts of the IEC 61558 series, under the general title: Safety of tra
45、nsformers, reactors, power supply units and combinations thereof, can be found on the IEC website. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the time of the next edition. When a particular subclause
46、 of Part 1 is not mentioned in this part, that subclause applies as far as is reasonable. Where this part states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adopted accordingly. In this part, the following print types are used: requirements proper: in roman type
47、; test specifications: in italic type; explanatory matters: in smaller roman type. In the text of this part the words in bold are defined in Clause 3. Subclauses, notes, figures and tables additional to those in Part 1 are numbered starting from 101; supplementary annexes are entitled AA, BB, etc. T
48、he 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, withdrawn, replaced by a revis
49、ed edition, or amended. NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation
