架空线路风振减振器的要求和试验

[中文适用范围]： 本文件适用于单根导线、地线或导线束（阻尼器直接附着在每根子导线上）的风振阻尼器。当指定与上述不同的电缆（如光纤复合地线（OPGW）、全介电自承式光缆（ADSS））的要求时，采购方可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采购方和供应商商定，并在采购合同中规定。附件 A 列出了采购方和供应商之间应商定的最低技术细节。在整个文件中，当测试适用于导线或地线的阻尼器时，使用术语“导线”。 [外文原描述]： 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.
