IEC 61854:2020 RLV包含官方IEC国际标准及其红线版本。Redline版本不是官方文档，它只有英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 61854:2020适用于架空线路导线束的垫片。它涵盖了刚性垫片、柔性垫片和垫片阻尼器。 它不适用于相间垫片、环箍垫片和粘合垫片。 本文档旨在涵盖撰写本文时最常用的生产线设计实践和垫片。可能存在其他可用的垫片，本文件中报告的特定测试可能不适用。 在某些情况下，测试程序和测试值由买方和供应商商定，并在采购合同中规定。买方最有能力评估预期的服务条件，这应该是建立测试严重性的基础。 附件A列出了买方和供应商之间需要商定的最低技术细节。 这第二版取消并取代了1998年出版的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)考虑在高温导体上应用垫片，在夹具滑动试验中规定额外的高温试验，并用于弹性和阻尼特性的表征； b)尽可能规定试验参数和验收值； c)尽可能避免同一试验的替代程序；d)为模拟短路电流试验引入更简单的试验装置； e)对紧固件部件如分离螺栓和锥形弹簧垫圈引入低温试验； f)对配备有杆附件的夹具的间隔件规定不同的子跨振荡测试程序； g)修改风成振动试验的试验程序； h)规定对装有带杆附件的夹具的间隔件进行风振测试的不同程序； i)重新编辑所有数字，使其更加清晰和统一； j)引入模拟短路电流试验的附加试验装置。 关键词:架空线路,间隔物

IEC 61854:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 61854:2020 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.
This document 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 document may not be applicable.
In some cases, test procedures and test values are left to agreement between purchaser 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.
This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Consider the application of spacers on high temperature conductors specifying additional high temperature tests in clamp slip tests and for the characterization of elastic and damping properties;
b) Specify as far as possible test parameters and acceptance values;
c) Avoid as far as possible the alternative procedures for the same test;
d) Introduce a simpler test device for the simulated short circuit current test;
e) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers;
f) Prescribe a different procedure for subspan oscillation tests on spacers equipped with clamps having rod attachments;
g) Modify the test procedure for the aeolian vibration tests;
h) Prescribe a different procedure for aeolian vibration tests on spacers equipped with clamps having rod attachments;
i) Re-edit all the figures in order to make them more clear and homogeneous;
j) Introduce an additional test device for the simulated short circuit current test.
