    25、ion sites 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 promote international co-operation on all questions concerning standardizat

    26、ion 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 Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is e

    27、ntrusted 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 also participate in this preparation. IEC collaborates closely with the In

    28、ternational 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 possible, an international consensus of opinion on the relevant subjects sin

    29、ce 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. While all reasonable efforts are made to ensure that the technical content

    30、 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 to apply IEC Publications transparently to the maximum extent possible

    31、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 attestation of conformity. Independent certification bodies provide conformity a

    32、ssessment 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 this publication. 7) No liability shall attach to IEC or its directors, e

    33、mployees, 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 indirect, or for costs (including legal fees) and expenses arising out of

    34、 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 the correct application of this publication. 9) Attention is drawn to t

    35、he 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 61558-2-23 has been prepared by IEC Technical Committee 96: Transformers, reactors, power

    36、supply units, and combinations thereof. This second edition cancels and replaces the first edition published in 2000. It constitutes a technical revision. The main changes consist of updating this Part 2-23 in accordance with IEC 61558-1:2005. This part has the status of a group safety publication i

    37、n accordance with IEC Guide 104: The preparation of safety publications and the use of basic safety publications and group safety publications. 4 61558-2-23 IEC:2010 The text of this standard is based on the following documents: FDIS Report on voting 96/359/FDIS 96/368/RVD Full information on the vo

    38、ting 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

    39、 is 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 construction sites. A list of al

    40、l 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 standards in this series will

    41、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 adapted accordingly. In this part

    42、, the following print 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 numbe

    43、red 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 d

    44、ate, 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. 61558-2-23 IEC:2010 5 SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND COMBINATIONS THEREOF Part 2-23: Particular requirements and tests for transformers and power supply units for construction sites 1 Scope Replacement: This part of IEC 61558 deals with the safety of transfo

    47、rmers for construction sites and power supply units incorporating transformers for construction sites. Transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here onward, th

    48、e term transformer covers transformers for construction sites and power supply units incorporating transformers for construction sites. This part is applicable to stationary or portable, single-phase or polyphase, air-cooled (natural or forced) independent or associated transformers, being isolating

    49、 or safety isolating dry- type transformers for the use on construction sites. The windings may be encapsulated or non-encapsulated. The rated supply voltage does not exceed 1 000 V a.c., and the rated supply frequency and the internal operating frequencies do not exceed 500 Hz. This standard used in combination with Part 2-16 for Switch mode power supply units (SMPS) is also applicable to power supplies w
