24、C:2010 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND COMBINATIONS THEREOF Part 2-9: Particular requirements and tests for transformers and power supply units for class III handlamps for tungsten filament lamps FOREWORD 1) The International Ele
25、ctrotechnical 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 fields
26、. 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 N
27、ational 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 Standardization
28、 (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 representati
29、on 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 cannot
30、 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 publications.
31、 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, acces
32、s 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 indiv
33、idual 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 upon,
34、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 of
35、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 61558-2-9 has been prepared by IEC technical committee 96: Transformers, reactors, power supply units and combinations thereof. This s
36、econd edition cancels and replaces the first edition published in 2002. 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 accor
37、dance with IEC Guide 104: 1997, The preparation of safety publications and the use of basic safety publications and group safety publications. 4 61558-2-9 IEC:2010 The text of this standard is based on the following documents: FDIS Report on voting 96/355/FDIS 96/362/RVD Full information on the voti
38、ng 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/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 i
39、s based on the second edition (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 for class III handlamps for tungsten f
40、ilament lamps. A list of all parts 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 sta
41、ndards in this series will be updated 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 adopte
42、d accordingly. In this part, the following 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 numb
43、ered starting from 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
44、date, the publication 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
45、 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 of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date
46、 of publication. 61558-2-9 IEC:2010 5 SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND COMBINATIONS THEREOF Part 2-9: Particular requirements and tests for transformers and power supply units for class III handlamps for tungsten filament lamps 1 Scope Replacement: This part of IEC 61558 deal
47、s with the safety of transformers for class III handlamps for tungsten filament lamps and power supply units incorporating transformers for class III handlamps for tungsten filament lamps. Transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electr
48、ical, thermal, mechanical and chemical aspects. Unless otherwise specified, from here onward, the term transformer covers transformers for class III handlamps for tungsten filament lamps and power supply units incorporating transformers for class III handlamps for tungsten filament lamps. This part
49、is applicable to stationary or portable single-phase air-cooled (natural or forced) independent or associated dry-type transformers. The windings may be encapsulated or non-encapsulated. 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 (SMPS) units i
