双分裂导线脱冰动力响应缩比模拟方法及试验
Reduced-scale modeling method and experiments on the dynamic responses of bundle conductor lines after ice-shedding
摘要
Abstract
Based on similarity principles,this study proposes a reduced-scale modeling and testing method to investigate the dynamic responses of twin-bundle conductor lines after ice-shedding.The processes of ice-accretion and subsequent shedding on sub-conductors of bundled conductors were successfully simulated.A reduced-scale experimental platform was established to measure the in-plane,out-of-plane,and torsional motions of conductors after ice-shedding,as well as the time histories of conductor tension and the longitudinal,vertical,and horizontal components of reaction forces at the suspension points.Reduced-scale tests were conducted on a representative twin-bundle conductor line under three conditions:partial ice-shedding and unzipping ice-shedding from a single sub-conductor,and asynchronous ice-shedding between two sub-conductors.The variations in jumping height,lateral swing amplitude,torsion angle,and conductor tension,along with the reaction forces at suspension points over time,were recorded and analyzed.关键词
