25、s for transformers and power supply units all for saving energy and other purposes 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 pr
26、omote 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 Specifications (PAS) and Guide
27、s (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 organizations liaising with the IEC al
28、so 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 matters express, as nearly as poss
29、ible, 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 Committees in that sense. Wh
30、ile 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 National Committees undertake
31、 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 does not provide any attestat
32、ion 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 have the latest edition of t
33、his 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 whatsoever, whether direct or i
34、ndirect, 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 publications is indispensable for
35、 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 standard IEC 61558-2-26 has bee
36、n prepared by IEC technical committee 96: Transformers, reactors, power supply units and combinations thereof. The text of this standard is based on the following documents: FDIS Report on voting 96/400/FDIS 96/404/RVD Full information on the voting for the approval of this standard can be found in
37、the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 61558-2-26 IEC:2013 This part 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 (
38、2005) of that standard. This part supplements or modifies the corresponding clauses in IEC 61558-1, so as to convert that publication into the IEC standard: Particular requirements and tests for transformers and power supply units all for saving energy and other purposes. A list of all parts of the
39、IEC 61558 series, under the general title: Safety of transformers, reactors, power supply units and combination 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 th
40、e time of the next edition. Where a particular subclause 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 adapted accordingly. In this part the following pr
41、int types are used: requirements proper: in roman type; test specifications: in italic type; explanatory matter: 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
42、101; supplementary annexes are entitled AA, BB, etc. 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 publicati
43、on will be reconfirmed, withdrawn, replaced by a revised 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 whi
44、ch to make products in accordance with the new requirements and to equip them for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication. 61558-2-
45、26 IEC:2013 5 SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND COMBINATIONS THEREOF Part 2-26: Particular requirements and tests for transformers and power supply units all for saving energy and other purposes 1 Scope Replacement: This part of IEC 61558 deals with the safety of transformers,
46、 power supply units and switch mode power supply units all for saving energy and other purposes in electrical installations by adjusting the output voltage and/or other electrical characteristics on the output circuits without interruption affected by the transformers, power supply unit and switch m
47、ode power supply unit. NOTE 1 Safety includes electrical, thermal and mechanicals aspects. The saving of energy is obtained by voltage stabilization and/or voltage adjusting of the electrical installation. This standard may also be used for power supply units and switch mode power supply units inten
48、ded to be used where adjusting of the voltage or other electrical characteristics is required by the final application. NOTE 2 An example of electrical installation is lighting installations, outdoor or indoor. NOTE 3 In special applications the reduction of the output voltage may affect the safety
49、and the performance of the supplied equipment. This part applies to single-phase or three-phase transformers, power supply units and switch mode power supply units all for saving energy which are air-cooled (natural or forced), independent or incorporated and containing transformers and/or power supply units from the following parts of the IEC 61558 series: Part 2-1: Particular requirements and tests for separating tr
