29、al 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 electronic fields. To this e
30、nd 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 committees; any IEC National Com
31、mittee 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 Standardization (ISO) in
32、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 has representation from al
33、l 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 accurate, IEC cannot be held r
34、esponsible 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 regional publications. Any diver
35、gence 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 some areas, access to IEC m
36、arks 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 including individual expe
37、rts 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 reliance upon, this IEC P
38、ublication 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 the elements of this IEC P
39、ublication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61439-5 has been prepared by subcommittee 17D: Low-voltage switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and
40、controlgear. This second edition cancels and replaces the first edition published in 2010. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the latest edition: confirmation that tests carried out on the most onerous PENDA are deem
41、ed to verify the performance of similar and less onerous assemblies of the same general construction and rating; more precise timing/conditions for impact force withstand tests for PENDAs designed for operation in an arctic climate; correction of the direction of the applied force in the static load
42、 test. 4 IEC 61439-5:2014 IEC 2014 The text of this standard is based on the following documents: CDV Report on voting 17D/492/CDV 121B/13/RVC 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
43、 drafted in accordance with the ISO/IEC Directives, Part 2. This standard is to be read in conjunction with 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
44、 this 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 5 that are new are numbered star
45、ting with 101. New annexes in this Part 5 are lettered AA, BB, etc. In this standard, terms written in small capitals are defined in Clause 3. The readers attention is drawn to the fact that Annex DD lists all of the “in-some-country” clauses on differing practices of a less permanent nature relatin
46、g to the subject of this standard. A list of all parts of the IEC 61439 series, under the general title Low-voltage switchgear and controlgear assemblies can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date in
47、dicated 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. IEC 61439-5:2014 IEC 2014 5 LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ASSEMBLIES Part 5: As
48、semblies for power distribution in public networks 1 Scope This part of IEC 61439 defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria: used for the distribution of electrical energy in three phase systems for which the
49、 rated voltage does not exceed 1 000 V a.c. (see Figure 101 for a typical distribution network); stationary; open ASSEMBLIES are not covered by this standard; suitable for installation in places where only skilled persons have access for their use, however, outdoor types may be installed in situations that are accessible to ordinary persons; for indoor or outdoor use. The object of this standard
