22、CAL COMMISSION _ RAILWAY APPLICATIONS FIXED INSTALLATIONS PARTICULAR REQUIREMENTS FOR AC SWITCHGEAR Part 3-1: Measurement, control and protection devices for specific use in a.c. traction systems Application guide FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organiz
23、ation 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 electronic fields. To this end and in addition to other activities, IE
24、C 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 committees; any IEC National Committee interested in the subject dealt wit
25、h 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 Standardization (ISO) in accordance with conditions determined by a
26、greement 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 has representation from all interested IEC National Committees. 3) I
27、EC 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 accurate, IEC cannot be held responsible for the way in which they are u
28、sed 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 regional publications. Any divergence between any IEC Publication and the
29、corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have
30、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 nature whatsoev
31、er, 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 publicatio
32、ns 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. International Standard
33、 IEC 62505-3-1 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. This standard is based on EN 50152-3-1. The text of this standard is based on the following documents: FDIS Report on voting 9/1221/FDIS 9/1234/RVD Full information on the voting for the app
34、roval 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. 4 62505-3-1 IEC:2009 A list of all parts of IEC 62505 series, under the general title Railway applications Fixed installation
35、s Particular requirements for a.c. switchgear, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publ
36、ication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 62505-3-1 IEC:2009 5 INTRODUCTION IEC 62505-3 is divided as follows: Part 3-1: Application guide; Part 3-2: Single-phase current transformers; Part 3-3: Single-phase inductive voltage tr
37、ansformers. This number of parts is subject to future additions as soon as a protection device is considered suitable for standard requirements. Part 3-1 is a guide. Further parts are normative and apply when the equipment is concerned with the specified characteristics. 6 62505-3-1 IEC:2009 RAILWAY
38、 APPLICATIONS FIXED INSTALLATIONS PARTICULAR REQUIREMENTS FOR AC SWITCHGEAR Part 3-1: Measurement, control and protection devices for specific use in a.c. traction systems Application guide 1 Scope This part of IEC 62505 provides assistance, guidance and requirements in the design of protection, con
39、trol and measuring systems in a.c. installations at traction voltages (see IEC 60850) intended to provide a power supply to traction systems. This application guide identifies the characteristics and parameters of equipment used in the measurement, control and protection of a.c. traction systems. Gu
40、idance is given in the correct use of protection. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including a
41、ny amendments) applies. IEC 62505 (all parts), Railway applications Fixed installations Particular requirements for a.c. switchgear IEC 60850, Railway applications Supply voltages of traction systems 3 Measurement Two types of measurements are made: a) measurement of current and voltage signals for
42、connecting to instruments and telemetering; b) measurement of current and voltage signals used for operating protection relays on over- current, low impedance, over/under-voltage and short circuit or distance protection. The class, ratio and burden should be selected from the values in IEC 62505-3-2
43、 or IEC 62505-3-3. The accuracy and purpose are dependant on the class selected. 4 Closing control systems 4.1 General The application of the features described below depends on the philosophy of the users control system. Closing control systems are usually only those which involve the electrical cl
44、osing of switchgear devices. Their effect is to permit or inhibit a closure depending on the status of the system (and plant) and the compliance of specified requirements. 62505-3-1 IEC:2009 7 4.2 Anti-pumping This system limits the closing device to effect a single attempt while the signal to close
45、 is maintained. If the device fails to complete a satisfactory close operation whilst the close signal is maintained, then attempts at further reclosing (pumping) are inhibited. An anti-pumping can be achieved in the closing control circuit in various ways, either by using circuit-breaker mechanism
46、auxiliary switches or a timing relay. It only allows a single closing pulse to the closing device, which resets when the initial closing signal is released. The purchaser should specify the need for anti-pumping feature. 4.3 Auto-reclose with variable reclose time and final lock out Auto-reclose is
47、only applied to line circuit-breakers and its purpose is to restore the system voltage to the overhead contact line automatically when there is a temporary loss of supply. On traction systems a temporary loss of supply is not always due to permanent short circuits and an auto-reclose system can enha
48、nce the reliability of the system. Auto-reclose is usually associated with a timing device which gives several attempts at reclosing with varying adjustable intervals of circuit dead time. After a prescribed number of unsuccessful recloses, then a lock out of the reclosing circuit should be instigat
49、ed. The lock out relay may then be either electrically or manually reset. The purchaser should specify the need for this requirement and the following information: a) number of recloses: e.g. 2 recloses then lock out; b) reclosing time intervals: e.g. 0,3 s, followed by 180 s, followed by 180 s (see 5.17 of IEC 62505-1); c) lock out reset: i.e. local or remote.
