摘要
为克服架空输电线路导线在复冰时和一定的空气动力条件下发生的舞动,本文研究了防舞措施。根据导线扭摆舞动机理,采用在输电线上加装失谐装置一防舞防扭重锤,并恰当地选择防舞防扭锤重量、数量、臂长以及安装位置,可有效地大幅度降低极限循环舞动与椭圆舞动的振幅值,提高输电线路在恶劣气候条件下安全运行的可靠性。
In order to reduce and eliminate the galloping of overhead transmission lines under certain wind condition, a new galloping-and twisting-proof pendulum is designed based on the aerodynamics of the galloping and twisting of the line. Through properly selecting the weight, length, number and location of the pendulum, the limit-circle and elliptical gallopings are greatly reduced and the operation security of the transmission lines under harsh weather condition is enhanced.
