    36、ILWAY APPLICATIONS DC SURGE ARRESTERS AND VOLTAGE LIMITING DEVICES Part 1: Metal-oxide surge arresters without gaps FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Commit

    37、tees). 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 Availab

    38、le 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 orga

    39、nizations 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 technical

    40、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 Nat

    41、ional 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 uniformity,

    42、 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 it

    43、self 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 that

    44、 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 natu

    45、re 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 referenced

    46、 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. Internation

    47、al Standard IEC 62848-1 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. This International Standard is based on EN 50526-1:2012, the main technical changes with regard to EN 50526-1:2012 are as follows: a) According to Resolution 52/33, taken by IEC tec

    48、hnical committee 9, this international standard should apply to both fixed installations and rolling stock, therefore the title is replaced with “Railway applications DC surge arresters and voltage limiting devices Part 1: Metal-oxide surge arresters without gaps”, and the scope of IEC 62848-1 is mo

    49、dified so that the standard can be used in both cases. b) As rolling stocks are supplied with many voltages as stated in IEC 60850, the surge arrester will limit voltage surge on DC systems specified in IEC 60850 with nominal voltage up to 3 kV. c) The European standards, listed in the original EN 50526-1:2012, are replaced with international standards, if they have corresponding internat
