26、IONAL ELECTROTECHNICAL COMMISSION _ LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ENCLOSED EQUIPMENT Part 1: Enclosed switch-disconnectors outside the scope of IEC 60947-3 to provide isolation during repair and maintenance work FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide

27、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 addition to other activit

28、ies, 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 interested in the subject de

29、alt 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 conditions determin

30、ed 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 National Committee

31、s. 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 the way in which the

32、y 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 any IEC Publication a

33、nd 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 conformity. IEC is not resp

34、onsible 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 of its technical co

35、mmittees 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 any other IEC Publica

36、tions. 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 be the subject of pa

37、tent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62626-1 has been prepared by subcommittee SC17B: Low-voltage switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.

At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 62626-1 IEC:2014 5 INTRODUCTION Enclosed switch-disconnectors covered by this part of IE

41、C 62626 are intended for use in various applications, to provide isolation of electrical equipment, especially motor circuits, during repair, cleaning and maintenance works. Such enclosed switch-disconnectors are sometimes known as “maintenance switches”, or “safety switches”. The name “safety switc

42、h” is also used for safety related position switches, inspection switches and switches for other applications, which are not covered by this standard. This part of IEC 62626 specifies additional requirements for enclosed switch-disconnectors according to IEC 60947-3 to provide isolation of electrica

43、l equipment during repair and maintenance work. Enclosed switch-disconnectors according to this standard are mounted close to the equipment which has to be isolated and are usually operated by instructed persons. NOTE 1 The term “safety switch” is not recognized in some countries as the same meaning

44、 given in this standard. NOTE 2 Switch-disconnectors do not necessarily meet the requirements for prevention of unexpected start, especially if there are energy sources other than electrical. 6 62626-1 IEC:2014 LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ENCLOSED EQUIPMENT Part 1: Enclosed switch-disconn

45、ectors outside the scope of IEC 60947-3 to provide isolation during repair and maintenance work 1 Scope This part of IEC 62626 applies to enclosed switches-disconnectors with rated voltages up to 1 000 V a.c. for repair and maintenance work or cleaning work in load circuits. Devices within the scope

46、 of this standard are derived from switch-disconnectors according to IEC 60947-3. Enclosed switch-disconnectors in this standard are suitable for isolation according to IEC 60947 series and are not supposed to be equipped with means for remote control or automatic switching to avoid unexpected or ac

47、cidental start. These devices are not intended to be used for operational switching, quick start and stop or jogging. NOTE 1 However, these kind of devices can provide the possibility to switch off electrical equipment (even in a critical situation or not). Devices within the scope of this standard

48、provide isolation of electrical equipment, especially in motor circuits, during repair and maintenance or cleaning works. Enclosed switch-disconnectors for various applications to provide isolation of electrical equipment during repair and maintenance work, named “maintenance switches”, are designat

49、ed hereafter as devices with: a) different classes; b) characteristics of each class; c) minimum test requirements; d) information to be marked on the equipment or made available by the manufacturer, for example in the catalogue. NOTE 2 This standard does not specify additional requirements that are necessary for the application of these switches, for example, in explosive atmospheres (e.g. ATEX in Europe). 2 Normative referen
