28、N _ LOW-VOLTAGE FUSES Part 6: Supplementary requirements for fuse-links for the protection of solar photovoltaic energy systems FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Nat
29、ional 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 International Standards, Technical Specifications, Technical Reports, Publ
30、icly 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 participate in this preparatory work. International, governmental and non- gover
31、nmental 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 between the two organizations. 2) The formal decisions or agreements of IEC o
32、n 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 Publications have the form of recommendations for international use and are accepte
33、d 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 any misinterpretation by any end user. 4) In order to promote international
34、 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 corresponding national or regional publication shall be clearly indicated in the latte
35、r. 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 services carried out by independent certification bodies. 6) All users should
36、 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 National Committees for any personal injury, property damage or other damage
37、 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 is drawn to the Normative references cited in this publication. Use of th
38、e 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 shall not be held responsible for identifying any or all such patent rights.
39、 International Standard IEC 60269-6 has been prepared by subcommittee 32B: Low-voltage fuses, of IEC technical committee 32: Fuses. The text of this standard is based on the following documents: FDIS Report on voting 32B/561/FDIS 32B/569/RVD Full information on the voting for the approval of this te
40、chnical report can be found in the report on voting indicated in the above table. This part is to be used in conjunction with IEC 60269-1:2006, Low-voltage fuses, Part 1: General requirements. This Part 6 supplements or modifies the corresponding clauses or subclauses of Part 1. 60269-6 IEC:2010 5 W
41、here no change is necessary, this Part 6 indicates that the relevant clause or subclause applies. Tables and figures which are additional to those in Part 1 are numbered starting from 101. Additional annexes are lettered AA, BB, etc. This publication has been drafted in accordance with the ISO/IEC D
42、irectives, Part 2. A list of all parts of the IEC 60269 series, under the general title: Low-voltage fuses, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webst
43、ore.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 60269-6 IEC:2010 LOW-VOLTAGE FUSES Part 6: Supplementary requirements for fuse-links for the protection of solar photovoltaic energy
44、 systems 1 General IEC 60269-1 applies with the following supplementary requirements. Fuse-links for the protection of solar photovoltaic (PV) energy systems shall comply with aIl requirements of IEC 60269-1, if not otherwise indicated hereinafter, and shall also comply with the supplementary requir
45、ements laid down below. NOTE The abbreviation “PV” (photovoltaic) is used in this document. 1.1 Scope and object These supplementary requirements apply to fuse-links for protecting PV strings and PV arrays in equipment for circuits of nominal voltages up to 1 500 V d.c. Their rated voltage may be up
46、 to 1 500 V d.c. NOTE 1 Such fuse-Iinks are commonly referred to as “PV fuse-links”. NOTE 2 In most cases, a part of the associated equipment serves the purpose of a fuse-base. Owing to the great variety of equipment, no general rules can be given; the suitability of the associated equipment to serv
47、e as a fuse- base should be subject to agreement between the manufacturer and the user. However, if separate fuse-bases or fuse-holders are used, they should comply with the appropriate requirements of IEC 60269 series. NOTE 3 PV fuse-links protect down stream inverter components such as capacitors
48、or the discharge of capacitors back into the arrays or array wiring up to the rated breaking capacity. The object of these supplementary requirements is to establish the characteristics of PV fuse- links in such a way that they can be replaced by other fuse-links having the same characteristics, pro
49、vided that their dimensions are identical. For this purpose, this standard refers in particular to a) the following characteristics of fuses: 1) their rated values; 2) their utilisation category; 3) their temperature rises in normal service; 4) their power dissipation; 4) their time-current characteristics; 6) their breaking capacity; 7) their dimensions or size (if applicable). b) type tes
