摘要:

本文首先阐述了多分裂导线次档距振荡的机理,分析了影响次档距振荡发生的几个主要因素,并以河南郑州尖山的国网公司舞动防治技术重点实验室的真型试验线路为依托,开展了真型试验线路自然次档距振荡的观测与分析。试验使用拥有多种功能的线路振动监测系统,定性和定量分析分裂导线次档距振荡的规律。研究结果表明,三相导线中,迎风侧边相导线容易形成稳定的次档距振荡,由于迎风侧边相导线对气流的干扰,中相导线几乎不发生次档距振荡。另外,各相子导线以及不同档距处的振荡状态皆有所不同,振荡的幅值和频率受到风速的影响也有所变化。

Abstract:

 

This paper firstly described the mechanism of bundle conductor subspan oscillation, and analyzed the main factors affecting subspan oscillation. The observation and analysis of the subspan oscillation characteristics of true-type test lines were carried out based on the true type test line in the key laboratory of galloping prevention and control technology of State Grid Corporation in Jianshan, Henan province, which used the line vibration monitoring system with a variety of functions to qualitatively and quantitatively analyze the subspan oscillation law of bundle conductor. The results show that the windward-side phase conductors of three-phase conductors are easy to form a stable subspan oscillation. Due to the interference of the windward-side phase conductors on the airflow, the intermediate phase conductors almost have no subspan oscillation. In addition, the oscillation state of each phase conductor and subspan is different, and the amplitude and frequency of oscillation change with the wind speed.
