24、ERNATIONAL ELECTROTECHNICAL COMMISSION _ SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND COMBINATIONS THEREOF Part 2-5: Particular requirements and test for transformer for shavers, power supply units for shavers and shaver supply units FOREWORD 1) The International Electrotechnical Commiss

25、ion (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 fields. To this end and in

26、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 National Committee int

27、erested 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 Standardization (ISO) in accordance

28、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 representation from all intereste

29、d 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 cannot be held responsible

30、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 publications. Any divergence betwe

31、en 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, access to IEC marks of con

32、formity. 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 individual experts and mem

33、bers 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 upon, this IEC Publication

34、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 of this IEC Publication

35、may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61558-2-5 has been prepared by IEC technical committee 96: Transformers, reactors, power supply units and combinations thereof. This second edition cancels

36、 and replaces the first edition published in 1997. It constitutes a technical revision. The main changes consist of updating this part in accordance with IEC 61558-1:2005 and adding power supply units to the scope. This part has the status of a group safety publication in accordance with IEC Guide 1

37、04: 1997, The preparation of safety publications and the use of basic safety publications and group safety publications. 4 61558-2-5 IEC:2010 The text of this standard is based on the following documents: FDIS Report on voting 96/353/FDIS 96/360/RVD Full information on the voting for the approval of

38、 this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with ISO/IEC Directives, Part 2. 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 edit

39、ion (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 test for transformer for shavers, power supply units for shavers and shaver supply units. A list of all parts

40、of the IEC 61558 series, under the general title: Safety of transformers, 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 updat

41、ed at the 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 adopted accordingly. In this part, the fo

42、llowing print types are used: requirements proper: in roman type; 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 additional to those in Part 1 are numbered starting from 101; supplementa

43、ry 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 publication will be recon

44、firmed, 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 which to make produ

45、cts in accordance with the new requirements and to equip themselves 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. 61558-2-5 IEC:2010

46、 5 SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND COMBINATIONS THEREOF Part 2-5: Particular requirements and test for transformer for shavers, power supply units for shavers and shaver supply units 1 Scope Replacement: This part of IEC 61558 deals with the safety of shaver transformers, po

47、wer supply units incorporating a shaver transformer, and shaver supply units. Shaver transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electrical, thermal, mechanical and chemical aspects. Unless otherwise specified, from here onward, the term t

48、ransformer covers shaver transformers and power supply units incorporating shaver transformers and shaver supply units. This part is applicable to stationary, single phase air-cooled (natural or forced), independent or associated dry- type transformers. The windings may be encapsulated or non-encaps

49、ulated. This standard is applicable to transformers and power supply (linear) with internal operational frequencies not exceeding 500 Hz. This standard used in combination with Part 2-16 for switch mode power supply units (SMPS) is also applicable to power supplies with internal operational frequencies higher than 500 Hz. Where the two requirements are in conflict the most severe take precedence. The rated su
