24、AL ELECTROTECHNICAL COMMISSION _ SERIES CAPACITORS FOR POWER SYSTEMS Part 3: Internal fuses 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
25、 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 Available Specifications (PAS)
26、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 organizations liaising with
27、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 matters express, as near
28、ly 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 National Committees in that
29、 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, IEC National Committees
30、 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 itself does not provide an
31、y 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 they have the latest ed
32、ition 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 d
33、irect 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 indispe
34、nsable 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 60143-3
35、has been prepared by IEC technical committee 33: Power capacitors and their applications. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the
36、 previous edition: The test procedure has been largely simplified. 4 IEC 60143-3:2015 IEC 2015 The text of this standard is based on the following documents: FDIS Report on voting 33/577/FDIS 33/579/RVD Full information on the voting for the approval of this standard can be found in the report on vo
37、ting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 60143 series, published under the general title Series capacitors for power systems, can be found on the IEC website. The committee has decided that
38、the contents of this 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 601
39、43-3:2015 IEC 2015 5 SERIES CAPACITORS FOR POWER SYSTEMS Part 3: Internal fuses 1 Scope This part of IEC 60143 applies to internal fuses designed to isolate faulty capacitor elements, to allow operation of the remaining parts of that capacitor unit and the bank in which the capacitor unit is connect
40、ed. Such fuses are not a substitute for a switching device such as a circuit-breaker, or for external protection of the capacitor bank, or any part thereof. The object of this part of IEC 60143 is: to formulate requirements regarding performance and testing; to provide a guide for coordination of fu
41、se and bank protection. NOTE External fuses for series capacitors are treated in IEC 60143-1:2004, Annex A: “Test requirements and application guide for external fuses and units to be externally fused“. 2 Normative references The following documents, in whole or in part, are normatively referenced i
42、n this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60143-1:2004, Series capacitors for power systems Part 1: General IEC 60143-2
43、2012, Series capacitors for power systems Part 2: Protective equipment for series capacitor banks 3 Terms and definitions For the purposes of this document, the terms and definitions contained in IEC 60143-1 and IEC 60143-2, as well as the following, apply. 3.1 rated voltage of a capacitor element
44、U Ner.m.s. value of the alternating voltage for which the capacitor element has been designed 4 Performance requirements 4.1 General The fuse is connected in series with the element(s) which the fuse is intended to isolate if the element(s) becomes faulty. The range of currents and voltages for the
45、fuse is therefore dependent on the capacitor design, and in some cases also on the design of the bank in which the fuse is connected. The operation of an internal fuse is in general determined by one or both of the two following factors: 6 IEC 60143-3:2015 IEC 2015 the discharge energy from elements
46、 or units connected in parallel with the faulty element or unit; the power-frequency fault current. 4.2 Disconnecting requirements The fuse shall enable the faulty element to be disconnected when electrical breakdown of elements occurs in a voltage range, in which u 1is the lowest, and u 2is the hig
47、hest (instantaneous) value of the voltage between the terminals of the unit at the instant of fault. The recommended values for u 1and u 2are the following: u 1= 0,5 2 U Nu 2= 2 U limFor u 1 , other values can be agreed upon between purchaser and manufacturer. The u 2value is of a transient nature.
48、The u 1and u 2values above are based on the voltage that may normally occur across the capacitor unit terminals at the instant of electrical breakdown of the element. The purchaser shall specify if the u 1value differs from the stated one. If so, the value stated in 3.2.3.1 shall be changed accordin
49、gly. The u 2value cannot be exceeded due to the overvoltage protector. A voltage lower than the u 1value can occur in service, but breakdowns are unlikely to take place under these conditions. 4.3 Withstand requirements 4.3.1 After operation, the gap in the blown fuse shall withstand full element voltage, plus any unbalance voltage due to fuse action, and any short-time transient overvoltages normally experienced dur
