33、ELECTRIC EQUIPMENT FOR ROLLING STOCK Part 2: Electrotechnical components General rules 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 t
34、o 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 Available Specifications (PAS) and G
35、uides (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 organizations liaising with the I
36、EC 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 matters express, as nearly as
37、 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 National Committees in that sens
38、e. 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, IEC National Committees unde
39、rtake 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 itself does not provide any att
40、estation 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 they have the latest edition
41、 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 nature whatsoever, whether direct
42、 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 publications is indispensabl
43、e 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. International Standard IEC 60077-2 has b
44、een prepared by IEC technical committee 9: Electrical equipment and systems for railways. This second edition cancels and replaces the first edition of IEC 60077-2, issued in 1999. It constitutes a technical revision. This edition includes the following main technical changes with regard to the prev
45、ious edition: a) Short circuit breaking capacity; b) Rated short-time withstand current; c) Critical currents range; d) Climatic conditions are specified. This standard is to be read in conjunction with IEC 60077-1. IEC 60077-2:2017 IEC 2017 5 The text of this standard is based on the following docu
46、ments: FDIS Report on voting 9/2267/FDIS 9/2279/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. A list of all parts in the IEC 60077 series, published under the general title Railway applications Electric equipme
47、nt for rolling stock, can be found on the IEC website. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstor
48、e.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. 6 IEC 60077-2:2017 IEC 2017 RAILWAY APPLICATIONS ELECTRIC EQUIPMENT FOR ROLLING STOCK Part 2: Electrotechnical components General rules
49、1 Scope In addition to the rules given in IEC 60077-1, this part of IEC 60077 provides general rules for all electrotechnical components installed in power circuits, auxiliary circuits, control and indicating circuits, etc., on railway rolling stock. The purpose of this document is to adapt the general rules given in IEC 60077-1 to all electrotechnical components for rolling stock, in or
