摘要
Abstract
In order to study the wind-induced vibration characteristics of transmission line conductors and their correlation with span distribution and micrometeorological data,in the data collection stage,PAVIC-type sensors are used for long-term monitoring of transmission line aeolian vibration,covering parameters such as vibration frequency,amplitude,and duration.Micrometeorological data within 200 m around the transmission line is collected,including wind speed,wind direction,temperature and humidity,and a gear spacing distribution model is established.Pearson correlation analysis and finite element simulation methods are used to analyze the vibration characteristics and influencing mechanisms of conductors with different spans under micrometeorological conditions.The analysis suggests that wind speed is significantly positively correlated with vibration frequency,amplitude and duration,and temperature has a significant positive impact on vibration amplitude.Combined with the time-varying characteristics of wind load,the increase in span and the increase in span unevenly will cause an increase in vibration amplitude.The influence of wind direction on bending amplitude shows a certain fluctuation.The increase in humidity has a certain inhibitory effect on the bending amplitude,showing a negative correlation trend.The research results provide a scientific basis for the design and maintenance of transmission lines.By optimizing the span and combining with micro-meteorological data,the stability of transmission lines can be improved and the risk of wind-induced vibration can be reduced.关键词
