25、NS THEREOF Part 2-15: Particular requirements and tests for isolating transformers for the supply of medical locations FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Com
26、mittees). 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 addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Avai
27、lable Specifications (PAS) and Guides (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 o
28、rganizations liaising with the IEC also 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 technic
29、al matters express, as nearly as possible, 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
30、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 for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformi
31、ty, IEC National Committees undertake 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
32、 itself does not provide any attestation 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 t
33、hat 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 members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any n
34、ature 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 or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referen
35、ced 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 may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. Internat
36、ional standard IEC 61558-2-15 has been prepared by IEC technical committee 96: Transformers, reactors, power supply units and combinations thereof. This second edition cancels and replaces the first edition published in 1999. It constitutes a technical revision. The main changes consist of updating
37、this part in accordance with IEC 61558-1:2005. This part has the status of a group safety publication in accordance with IEC Guide 104:2010, The preparation of safety publications and the use of basic safety publications and group safety publications. 4 61558-2-15 IEC:2011 The text of this standard
38、is based on the following documents: FDIS Report on voting 96/384/FDIS 96/385/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/IEC Directives, Part 2. T
39、his 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 (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: Pa
40、rticular requirements and tests for isolating transformers for the supply of medical locations. A list of all parts of the 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 thi
41、s 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. 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 “additio
42、n“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. In this part, 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
43、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. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated o
44、n 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 revised edition, or amended. NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and t
45、esting 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 of the committee that the con
46、tent of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication. 61558-2-15 IEC:2011 5 SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND COMBINATIONS THEREOF Part 2-15: Particular requirements and tests for isolating transformers for t
47、he supply of medical locations 1 Scope Replacement: This part of IEC 61558 deals with safety aspects of isolating transformers for the supply of medical locations. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here onward, the term transformer co
48、vers isolating transformers for the supply of medical locations. This part is applicable to stationary, single-phase or three-phase, air-cooled (natural or forced) independent dry-type isolating transformers for the supply of medical IT systems for group 2 medical locations, designed to be permanent
49、ly connected to the fixed wiring and intended to form the IT power system on the secondary side. The windings may be encapsulated or non- encapsulated. NOTE 2 IT power systems are defined in IEC 60364-1. NOTE 3 The installation rules for medical IT systems for group 2 medical locations are covered by IEC 60364-7-710. NOTE 4 Transformers covered by this standard are intended for the supply of medical locati
