26、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 end and in addit

27、ion 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 interest

28、ed 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

29、 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 IE

30、C 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

31、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 divergence between a

32、ny 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 conform

33、ity. 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

34、 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 a

35、ny 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

36、be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62271-106 has been prepared by subcommittee 17A: High-voltage switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear. This stand

37、ard cancels and replaces the second edition of IEC 60470 published in 1999. It constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60470:1999: Scope and object: The voltage range covered by the standard was expanded from 12 kV to 24

38、 kV. Overload relay calibration and testing is not covered by this standard. 3 Terms and definitions: Added definitions for capacitor switching classes. 4.1 Rated voltage: Added 15, 17,5 and 24 kV as standard voltage values. 4.109.2 Starting duty of reduced-voltage starters: Added ratings for autotr

39、ansformer and reactor starters (was in the testing section). 4 62271-106 IEC:2011 4.112 Rated capacitive switching currents: Added capacitor switching current ratings. 5.101 Protective relays: Removed the requirements for overload relays. This section is obsolete since there are only a few MV starte

40、rs fitted with thermal overload relays and electronic relays have their own standards. 6.2.5 Application of the test voltage and test conditions (former 6.2.2 b): Changed wording of requirement for impulse across the open gap of vacuum contactors. 6.4.2 Auxiliary circuits: The requirement for resist

41、ance checks of auxiliary circuits was deleted. 6.5.5.104 Temperature rise of the auto-transformer or reactor for two-step auto-transformer or reactor starters: Reworded to transfer ratings to subclause 4.109.2. 6.102.9 Condition following making and breaking tests: Gave specific direction as to what

42、 the tolerance should be based on where the resistance was to be checked. 6.104 Short-circuit current making and breaking tests: Clarified test conditions for short- circuit testing. 6.109 Capacitive current switching tests: Added capacitive current switching tests. Annex B: Added Table B.1 Toleranc

43、es on test quantities for type test. This standard is to be read in conjunction with IEC 62271-1:2007, to which it refers and which is applicable unless otherwise specified in this standard. In order to simplify the indication of corresponding requirements, the same numbering of clauses and subclaus

44、es is used as in IEC 62271-1. Amendments to these clauses and subclauses are given under the same references whilst additional subclauses are numbered from 101. The text of this standard is based on the following documents: FDIS Report on voting 17A/971/FDIS 17A/976/RVD Full information on the votin

45、g 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 the ISO/IEC Directives, Part 2. The list of all parts of the IEC 62271 series under the general title, High-voltage switchgear and controlgear,

46、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:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirm

47、ed, withdrawn, replaced by a revised edition, or amended. 62271-106 IEC:2011 5 HIGH-VOLTAGE SWITCHGEAR AND CONTROLGEAR Part 106: Alternating current contactors, contactor-based controllers and motor-starters 1 General 1.1 Scope and object This part of IEC 62271 is applicable to a.c. contactors and/o

48、r contactor-based controllers and motor-starters designed for indoor installation and operation at frequencies up to and including 60 Hz on systems having voltages above 1 000 V but not exceeding 24 000 V. It is applicable only to three-pole devices for use in three-phase systems, and single-pole de

49、vices for use in single-phase systems. Two-pole contactors and starters for use in single- phase systems are subject to agreement between manufacturer and user. Contactors and/or starters dealt with in this standard typically do not have adequate short-circuit interruption capability. In this context, this standard gives requirements for motor starters a
