230 kV亚马逊河大跨越工程跨越段导线防振创新要点
Innovation of Anti-Vibration Scheme for Overhead Conductor of the Crossing Section in 230 kV Amazon River Crossing Project

为解决亚马逊河大跨越工程大钢比、大张力和单导线工况造成的防振难题，提出了将档距平均分为两段，并分别设计防振方案的方法。采用能量平衡法对试验数据进行处理，证明了本文所提出方法相对于传统方法的优越性。该方法对于大跨越工程中超大档距、大张力和大钢比的导线防振具有重要参考价值。
In order to solve the difficult problem of conductor anti-vibration caused by large tension and single conductor in Amazon River crossing project. The method of dividing the span into two sections and design anti-vibration scheme separately is proposed. The energy balance method is used to process the test data, which proves the advantages of the method proposed in this paper over the traditional method. The new method is of great significance for the anti-vibration of conductors with large ratio of steel area to aluminum-alloy area.
