本文设计并进行了导线风振的室内试验，通过试验研究了导线自减振和钢丝阻尼器(BRETELE)的功率耗散特性。此外，还建立了估算钢丝绳阻尼器耗能的理论方法。结果表明，导线张力和振动频率对其自减振性能有很大影响，而导线阻尼器的固有频率与其长度有关，导线阻尼器的长度对其减振效果有显著影响。试验结果验证了计算钢丝绳阻尼器耗能的理论方法的可靠性。这些结论可为输电线路工程的研究和抗振设计提供参考。
In this paper, laboratory tests on conductor aeolian vibration were designed and carried out, through which the power dissipation characteristics of conductor self-damping and wire dampers(bretelles) were investigated. In addition, the theoretical method was established to estimate the power dissipated by wire damper. The results show that conductor tension and vibration frequency have great influences on its self-damping property; furthermore, the results present that the natural frequency of wire damper is related with its length and the length of wire damper has significant impact on its anti-vibration effect. The theoretical method for calculating the power dissipated by wire damper was verified to be reliable by the test results. These conclusions can provide references for the research and anti-vibration design of transmission line engineering.
