Abstract

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.
