25、ternational Electrotechnical 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 el

26、ectronic fields. To this end 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 commit

27、tees; any IEC National Committee 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

28、Standardization (ISO) in 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 h

While all reasonable efforts are made to ensure that the technical content of IEC Publications is accur

Any divergence 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 so

International Standard IEC 62217 has been prepared by IEC technical committee 36: Insulators. This second edition cancels and replaces the first e

36、dition published in 2005. This edition constitutes a technical revision. This edition includes a significant technical change with respect to the previous edition. The first edition of IEC 62217 (2005) included two other alternative tracking and erosion tests (a 5 000 hour multi-stress test and a tr

37、acking wheel test) which were based on tests developed by CIGRE and utilities. These tests are no longer given as normative alternatives following the results of a study/questionnaire by TC 36 on the relative merits of all three tracking and erosion tests. The 5 000 hour multi-stress test and a trac

38、king wheel test are described in IEC/TR 62730 (2012). 62217 IEC:2012 5 The text of this standard is based on the following documents: FDIS Report on voting 36/321/FDIS 36/324/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the ab

39、ove table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 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 specif

40、ic publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 62217 IEC:2012 INTRODUCTION Polymeric insulators consist either of one insulating material (resin insulators) or two or several insulating materials (composite insulators). The

41、insulating materials are generally cross-linked organic materials synthesised from carbon or silicon chemistry and form the insulating body. Insulating materials can be composed from organic materials containing various inorganic and organic ingredients, such as fillers and extenders. End fittings a

42、re often used at the ends of the insulating body to transmit mechanical loads. Despite these common features, the materials used and the construction details employed by different manufacturers may be widely different. The tests given in this standard are those which are, in general, common to a gre

43、at majority of insulator designs and materials, whatever their final application. They have been regrouped in this standard to avoid repetition in the relevant product standards and drift between procedures as the various product standards are drafted or revised. The majority of these tests have bee

44、n grouped together as “Design tests“, to be performed only once for insulators of the same design. The design tests are intended to eliminate insulator designs, materials or manufacturing technologies which are not suitable for high-voltage applications. The influence of time on the electrical prope

45、rties of the complete polymeric insulator and its components (core material, housing, interfaces etc.) has been considered in specifying the design tests in order to ensure a satisfactory lifetime under normal operating and environmental conditions. Pollution tests, according to IEC 60507 or IEC 612

46、45, are not included in this document, the applicability of their methodology to composite insulators not having been proven and still requiring study by CIGRE. The results of such pollution tests performed on insulators made of polymeric materials do not correlate with experience obtained from serv

47、ice. Specific pollution tests for polymeric insulators are still under consideration. The 1 000 hour salt-fog tracking and erosion test given in this second edition of IEC 62217 is considered as a screening test intended to reject materials or designs which are inadequate. This test is not intended

48、to predict long term performance for insulator designs under cumulative service stresses. For more information, see Annex C. The first edition of IEC 62217 (2005) included two other alternative tracking and erosion tests (a 5 000 hour multi-stress test and a tracking wheel test) which were based on

49、tests developed by CIGRE and utilities. These tests are no longer given as normative alternatives following the results of a study/questionnaire by TC 36 on the relative merits of all three tracking and erosion tests. The 5 000 hour multi-stress test and a tracking wheel test are described in IEC/TR 62730 (2012). Composite insulators are used in both a.c. and d.c. applications. In spite of this fact a specifi
