标准摘要
[中文适用范围]: 本文件适用于旨在用于单导线或地线或导线束的风振阻尼器,其中阻尼器直接连接到每个子导线上。 购买方在指定其他类型的风振阻尼器或用于与上述不同的导线或电缆(例如光纤复合架空地线(OPGW)、全介质自承式光缆(ADSS))的Stockbridge阻尼器要求时,可以采用本文件的部分内容。 在某些情况下,测试程序和测试值由购买方和供应商之间达成协议,并在采购合同中说明。 附录A列出了购买方和供应商之间需要达成协议的最低技术细节。 在本文件中,当测试适用于导线或地线的阻尼器时,使用“导线”一词。 [外文原描述]: IEC 61897:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version 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 61897:2020 applies to aeolian vibration dampers intended for single conductors or earth wires or conductor bundles where dampers are directly attached to each subconductor. The purchaser may adopt part(s) of this document when specifying requirements for cables different from those mentioned above (e.g. optical ground wires (OPGW), all dielectric self-supporting optical cables (ADSS)). In some cases, test procedures and test values are left to agreement between the purchaser and the supplier and are stated in the procurement contract. Annex A lists the minimum technical details to be agreed between purchaser and supplier. Throughout this document, the word “conductor” is used when the test applies to dampers for conductors or earth wires. 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, in addition to Stockbridge type aeolian vibration dampers, also spiral aeolian vibration dampers and elastomeric aeolian vibration dampers. b) Consider the application of dampers on high temperature conductors, specifying additional high temperature tests in clamp slip tests. c) Simplify the procedure of the damper effectiveness evaluation. d) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers. e) Include figures showing the test arrangements for the main mechanical tests.
