23、otechnical 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 activities, IEC publishes International Standards, Technical Specifica
24、tions, 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 dealt with may participate in this preparatory work. Internationa
25、l, 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 determined by agreement between the two organizations. 2) The formal de
26、cisions 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 Committees. 3) IEC Publications have the form of recommendations for int
27、ernational 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 they are used or for any misinterpretation by any end user. 4) In
28、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 and the corresponding national or regional publication shall be
29、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) All users should ensure that they have the latest edition of this publication. 7) No liability
30、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 or other damage of any nature whatsoever, whether direct or indirect, or for costs (including
31、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 publication. Use of the referenced publications is indispensable for the correct application of this
32、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 patent rights. International Standard IEC 60282-2 has been prepared by subcommittee 32A: High
33、-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 previous edition concern the following: Class C has been eliminated; TRV values have been rev
34、iewed 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 for fuse-links has been included; an homogeneous series has been redefined.

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 decide
37、d that the contents of this 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
38、 amended.

39、oors 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 extinguished by the expulsion effects of the gases produced by the arc. Expulsion fuses are classified according to the TRV (transient recovery voltage) capa
40、bility in classes A and B. This standard covers only the performance of fuses, each one comprising a specified combination of fuse-base, fuse-carrier and fuse-link which have been tested in accordance with this standard; successful performance of other combinations cannot be implied from this standa
41、rd. This standard may also be used for non-expulsion fuses in which the interruption process waits for natural current zero to clear the circuit. NOTE 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 a
42、nd for transformer circuit applications are subject to additional requirements (see IEC 60549 1 1or IEC 60787 2). NOTE 3 This standard does not cover load-switching nor fault-making capabilities. Information regarding requirements related to switching capabilities may be found in IEC 60265-1 3. NOTE
43、 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 references The following referenced documents are indispensable for the application of this
