No. Date Sector Committee, was published under the authority of the Standards Committee and comes into effect on 15 December 1998 BS EN 618541998 Text affected National foreword This British Standard is the English language version of EN 61854:19
3、98. It is identical with IEC 61854: 1998. The UK participation in its preparation was entrusted to Technical Committee PEU1 1, Overhead lines, which has the responsibility to: - aid enqukers to understand the text; - present to the responsible internationaVEuropean committee any enquiries on the int
4、erpretation, or proposals for change, and keep the UK interests informed; - monitor related intemtional and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secrem. From 1 January 1997, al IEC publications ha
5、ve the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is dram to the fact that CEN
6、and CENELEC Standards normally include an annex which lists nonnative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the sect
7、ion entided “International Standards Correspondence Index“, or by using the “Find“ facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.

28、HEAD LINES - REQUIREMENTS AND TESTS FOR SPACERS 1 Scope This International Standard applies to spacers for conductor bundles of overhead lines. It covers rigid spacers, flexible spacers and spacer dampers. It does not apply to interphase spacers, hoop spacers and bonding spacers. NOTE - This standar
29、d is written to cover the line design practices and spacers most commonly used at the time of writing. There may be other spacers available for which the specific tests reported in this standard may not be applicable. In many cases, test procedures and test values are left to agreement between purch
30、aser and supplier and are stated in the procurement contract. The purchaser is best able to evaluate the intended service conditions, which should be the basis for establishing the test severity. In annex A, the minimum technical details to be agreed between purchaser and supplier are listed. 2 Norm
31、ative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication of this standard, the editions indicated were valid. All normative documents are subject to revision, and part
32、ies to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

41、ose of this International Standard the definitions of the International flectrotechnical Vocabulary (IEV) apply, in particular IEC 60050(466). Those which differ or do not appear in the IEV are given below. 3.1 rigid spacer spacer allowing no relative movement between the subconductors at the spacer
42、 location 3.2 flexible spacer spacer allowing relative movements between the subconductors at the spacer location 3.3 spacer system complex of spacers and the relevant in-span distribution 4 General requirements 4.1 Design The spacer shall be designed as to maintain subconductor spacing (at spacer l
43、ocations), within any prescribed limits, under all conditions of service excluding short-circuit currents; prevent, in subspans between spacers, physical contact between subconductors, except during the passage of short circuit currents when the possibility of contact is accepted provided that the s
44、pecified spacing is restored immediately following fault clearance; withstand mechanical loads imposed on the spacer during installation, maintenance and service (including short circuit conditions) without any component failure or unacceptable permanent deformation; avoid damage to the subconductor
45、 under specified service conditions; be free from unacceptable levels of corona and radio interference under specified service conditions; be suitable for safe and easy installation. For the bolted and latching clamp the design shall retain all parts when opened for attachment to the conductor; ensu
46、re that individual components will not become loose in service; be capable of being removed and re-installed on the subconductors without damage to the spacer or subconductors; maintain its function over the entire service temperature range; avoid audible noise. NOTE - Other desirable characteristic
47、s, which are not essential to the basic functions of the spacer but which may be advantageous to the purchaser, include: - verification of proper installation from the ground, - ease of installation and removal from energized lines. 4.2 Materials 4.2.1 General Spacers shall be made of any materials
48、suitable for their purpose. Unless additional requirements are stated, the material shall conform to the requirements of IEC 61284. 4.2.2 Non-metallic materials In addition to the requirements of IEC 61284, the conductivity of the various non-metallic components shall be such that when properly inst
49、alled - potential differences between metallic components do not cause damage due to discharge; - any current flow between subconductors does not degrade spacer materials. 4.3 Mass, dimensions and tolerances Spacer mass and significant dimensions, including appropriate tolerances, shall be shown on contract drawings. NOTE - Tolerances applied to the mass and to the dimensions should ensure that the spacers meet their specified mechanical and electrical requirements. 4.4 Protection against corrosion In addition to the applicable requirements of IEC 612
