28、AL ELECTROTECHNICAL COMMISSION _ RAILWAY APPLICATIONS FIXED INSTALLATIONS PARTICULAR REQUIREMENTS FOR AC SWITCHGEAR Part 2: Disconnectors, earthing switches and switches with nominal voltage above 1 kV FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for st

29、andardization 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 addition to other activities, IEC publishes

30、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 interested in the subject dealt with may partic

31、ipate 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 with conditions determined by agreement bet

32、ween 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 interested IEC National Committees. 3) IEC Publicati

33、ons 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 for the way in which they are used or for a

34、ny 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 between any IEC Publication and the correspondin

35、g 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 conformity. IEC is not responsible for any ser

36、vices 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 members of its technical committees and IEC Na

37、tional 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 or any other IEC Publications. 8) Attention

38、 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 may be the subject of patent rights. IEC sh

39、all not be held responsible for identifying any or all such patent rights. International Standard IEC 62505-2 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. This standard is based on EN 50152-2. This second edition cancels and replaces the first editio

40、n issued in 2009. It constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: This standard was revised to reflect the latest versions of standards referenced and to remove text already included in the IEC 62271 series. The scope was extended t

41、o include single- phase and two-phase devices. Definitions were added to provide the necessary precision and to meet the needs of railway applications. Table 1 was reworked according to the changes of 4 IEC 62505-2:2016 IEC 2016 IEC 62497-1:2010, Table A.2 and Table B.1. Table 2 Coordination table o

42、f rated values for devices of the previous version was removed. Ratings previously given under the clause type tests were moved to the new Table 2 Mechanical endurance classes and recommended use. Requirements for combined equipment were added to provide guidance if components of different manufactu

43、rers are used in one switching device. The text of this standard is based on the following documents: FDIS Report on voting 9/2098/FDIS 9/2134/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

44、been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 62505 series, under the general title Railway applications Fixed installations Particular requirements for a.c. switchgear, can be found on the IEC website. The committee has decided that the contents of this

45、publication will remain unchanged until the stability date indicated on the IEC website 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. IEC 62505-2:2016 IEC 2016 5

46、INTRODUCTION The IEC 62505 series under the generic title Railway applications Fixed installations Particular requirements for a.c. switchgear, is divided as follows: Part 1: Circuit-breakers with nominal voltage above 1 kV. Part 2: Disconnectors, earthing switches and switches with nominal voltage

47、above 1 kV. Part 3-1: Measurement, control and protection devices for specific use in a.c. traction systems Application guide. Part 3-2: Measurement, control and protection devices for specific use in a.c. traction systems Single-phase current transformers. Part 3-3: Measurement, control and protect

48、ion devices for specific use in a.c. traction systems Single-phase inductive voltage transformers. IEC 62505-2 has to be used in conjunction with IEC 62271-1:2007, IEC 62271-102:2001 and its Amendment 1:2011 and/or IEC 62271-103:2011, depending on the equipment involved. References in subclauses of

49、IEC 62271-1, IEC 62271-102 and IEC 62271-103 need to be replaced by references to applicable subclauses in this standard as far as reasonably possible. References in subclauses in IEC 62271-102 need to be to IEC 62271-1 instead of IEC 60694. Where a particular clause of IEC 62271-1, IEC 62271-102 or IEC 62271-103 is not mentioned in this standard, that clause
