31、ternational 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 standardization in the electrical and el
32、ectronic 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 entrusted to technical commit
33、tees; 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 International Organization for
34、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 since each technical committee h
35、as 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 of IEC Publications is accur
36、ate, 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 in their national and regiona
37、l 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 assessment services and, in so
38、me 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, employees, servants or agents
39、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 the publication, use of, or
40、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 the possibility that some of t
41、he 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 62128-3 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. This standard is
42、 based on EN 50122-3. The text of this standard is based on the following documents: FDIS Report on voting 9/1805/FDIS 9/1838/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. 62128-3 IEC:2013 5 This publication ha
43、s been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62128 series, published under the general title Railway applications Fixed installations Electrical safety, earthing and the return circuit, can be found on the IEC website. The committee has decided tha
44、t 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 date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 62
45、128-3 IEC:2013 RAILWAY APPLICATIONS FIXED INSTALLATIONS ELECTRICAL SAFETY, EARTHING AND THE RETURN CIRCUIT Part 3: Mutual interaction of a.c. and d.c. traction systems 1 Scope This part of IEC 62128 specifies requirements for the protective provisions relating to electrical safety in fixed installat
46、ions, when it is reasonably likely that hazardous voltages or currents will arise for people or equipment, as a result of the mutual interaction of a.c. and d.c. electric traction systems. It also applies to all aspects of fixed installations that are necessary to ensure electrical safety during mai
47、ntenance work within electric traction systems. The mutual interaction can be of any of the following kinds: parallel running of a.c. and d.c. electric traction systems; crossing of a.c. and d.c. electric traction systems; shared use of tracks, buildings or other structures; system separation sectio
48、ns between a.c. and d.c. electric traction systems. Scope is limited to basic frequency voltages and currents and their superposition. This standard does not cover radiated interferences. This standard applies to all new lines, extensions and to all major revisions to existing lines for the followin
49、g electric traction systems: a) railways; b) guided mass transport systems such as: 1) tramways, 2) elevated and underground railways, 3) mountain railways, 4) trolleybus systems, and 5) magnetically levitated systems, which use a contact line system; c) material transportation systems. The standard does not apply to: d) mine traction systems in underground mines; e) cranes, transportab
