24、EC) 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 electronic fields. To this end and in additi
25、on 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 committees; any IEC National Committee intereste
26、d 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 Standardization (ISO) in accordance with
27、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 has representation from all interested IEC
28、 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 accurate, IEC cannot be held responsible for t
29、he 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 regional publications. Any divergence between an
30、y 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 some areas, access to IEC marks of conformi
31、ty. 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 including individual experts and members
32、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 reliance upon, this IEC Publication or an
33、y 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 the elements of this IEC Publication may b
34、e the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61439-6 has been prepared by subcommittee 17D: Low-voltage switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and controlgear. Thi
35、s first edition of IEC 61439-6 cancels and replaces the third edition of IEC 60439-2 (2000) and its Amendment 1 (2005), and constitutes a technical revision. This edition of IEC 61439-6 includes the following significant technical changes with respect to the latest edition of IEC 60439-2: alignment
36、on the second edition of IEC 61439-1 (2011) regarding the structure and technical content, as applicable; introduction of new verifications, accordingly; correction of inconsistencies in resistance, reactance and impedance measurements and calculations; numerous editorial improvements. 4 61439-6 IEC
37、:2012 The text of this standard is based on the following documents: FDIS Report on voting 17D/452/FDIS 17D/454/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. This publication has been drafted in accordance with
38、 the ISO/IEC Directives, Part 2. This standard is to be read in conjunction with the second edition of IEC 61439-1. The provisions of the general rules dealt with in IEC 61439-1 (hereinafter referred to as Part 1) are only applicable to this standard insofar as they are specifically cited. When this
39、 standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. Subclauses that are numbered with a 101 (102, 103 etc.) suffix are additional to the same subclause in Part 1. Tables and figures in this Part 6 that are new are numbered starting
40、with 101. New annexes in this Part 6 are lettered AA, BB, etc. The “in some countries” notes regarding differing national practices are contained in the following subclauses: 5.4 A list of all parts of the IEC 61439 series, under the general title Low-voltage switchgear and controlgear assemblies ca
41、n 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:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed
42、, withdrawn, replaced by a revised edition, or amended. 61439-6 IEC:2012 5 LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ASSEMBLIES Part 6: Busbar trunking systems (busways) 1 Scope NOTE 1 Throughout this part, the abbreviation BTS is used for a busbar trunking system. Where reference to Part 1 is made, th
43、e term ASSEMBLY therefore reads as “BTS”. This part of IEC 61439 lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low voltage BTS (see 3.101) as follows: BTS for which the rated voltage does not exceed
44、 1 000 V in case of a.c. or 1 500 V in case of d.c.; BTS intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment; BTS designed for use under special service conditions, for example in
45、 ships, in rail vehicles, and for domestic applications (operated by unskilled persons), provided that the relevant specific requirements are complied with; NOTE 2 Supplementary requirements for BTS in ships are covered by IEC 60092-302. BTS designed for electrical equipment of machines. Supplementa
46、ry requirements for BTS forming part of a machine are covered by the IEC 60204 series. This standard applies to all BTS whether they are designed, manufactured and verified on a one-off basis or fully standardized and manufactured in quantity. The manufacture and/or assembly may be carried out by a
47、manufacturer other than the original manufacturer (see 3.10.1 and 3.10.2 of Part 1). This standard does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, etc. which will comply with the relevant product standard. This standard
48、 does not apply to the specific types of ASSEMBLIES covered by other parts of the IEC 61439 series, to supply track systems in accordance with IEC 60570, to cable trunking and ducting systems in accordance with the IEC 61084 series, nor to power track systems in accordance with the IEC 61534 series.
