30、ommission (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 a

31、nd 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 Committ

32、ee 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 acco

33、rdance 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 all in

34、terested 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 respo

35、nsible 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 divergenc

36、e between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) A

37、ll 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 committees and IEC National Committees for any personal injury, property damage

38、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 Publications. 8) Attention is drawn to the Normative references cited in this publica

39、tion. 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 patent rights. IEC shall not be held responsible for identifying any or all such

40、 patent rights. International Standard IEC 60282-2 has been prepared by subcommittee 32A: High-voltage fuses, of IEC technical committee 32: Fuses. This third edition cancels and replaces the second edition, published in 1995, and constitutes a technical revision. The main changes with regard to the

41、 previous edition concern the following: Class C has been eliminated; TRV values have been reviewed and, where appropriate, harmonized with IEC 62271-100:2001, its amendment 1 (2002) and amendment 2 (2006); tests for non-ceramic insulators have been included; a lightning surge impulse withstand test

42、 for fuse-links has been included; an homogeneous series has been redefined. 60282-2 IEC:2008 5 The text of this standard is based on the following documents: FDIS Report on voting 32A/261/FDIS 32A/264/RVD Full information on the voting for the approval of this standard can be found in the report on

43、 voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 60282 series, under the general title High-voltage fuses, can be found on the IEC website. The committee has decided that the contents of this

44、 publication will remain unchanged until the maintenance result 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, withdrawn, replaced by a revised edition, or amended. 6 60282-2 IEC:200

45、8 HIGH-VOLTAGE FUSES Part 2: Expulsion fuses 1 Scope This part of IEC 60282 specifies requirements for expulsion fuses designed for use outdoors or indoors on alternating current systems of 50 Hz and 60 Hz, and of rated voltages exceeding 1 000 V. Expulsion fuses are fuses in which the arc is exting

46、uished by the expulsion effects of the gases produced by the arc. Expulsion fuses are classified according to the TRV (transient recovery voltage) capability in classes A and B. This standard covers only the performance of fuses, each one comprising a specified combination of fuse-base, fuse-carrier

47、 and fuse-link which have been tested in accordance with this standard; successful performance of other combinations cannot be implied from this standard. This standard may also be used for non-expulsion fuses in which the interruption process waits for natural current zero to clear the circuit. NOT

48、E 1 See Clause 5 and Clause 12 for specific information regarding the selection of fuse class. NOTE 2 Fuses required for the protection of capacitors and for transformer circuit applications are subject to additional requirements (see IEC 60549 1 1or IEC 60787 2). NOTE 3 This standard does not cover

49、 load-switching nor fault-making capabilities. Information regarding requirements related to switching capabilities may be found in IEC 60265-1 3. NOTE 4 This standard does not cover aspects related to the level of noise, nor the emission of hot gases inherent to some types of expulsion fuses during the process of interruption of fault currents. 2 Normative ref
