摘要
针对架空输电线路舞动特点,结合导线、分裂数及排列形式等方面的技术参数,开展了架空输电线路导线限位式防舞技术研究。基于对舞动特点的分析,提出了架空输电线路导线限位式防舞机理及防舞技术,运用有限元分析软件对提出的架空输电线路导线限位式防舞方案进行了力学仿真分析。对新设计的限位式防治装置进行了样品试制,并开展了力学性能试验、电气性能试验及舞动防治效果评估试验等。对研制的限位式防治装置开展试点应用工作,试点应用结果表明:新提出的架空输电线路导线限位式防舞技术能够有效地提升架空输电线路的防舞能力,保障线路安全运行。
The position-limited anti-dancing technique of conductor for overhead transmission lines was researched based on the galloping characteristics of overhead transmission lines combined with the technical parameters of conductor, splitting numbers and arrangement form. By analyzing the dancing characteristics, we put forward an anti-dancing mechanism and anti-dancing technology of conductor for overhead transmission lines. Using the finite element analysis software, we carried out the mechanical simulation analysis of the proposed conductor's position-limited anti-dancing scheme for overhead transmission lines. Trial-manufacture sample of a new design position-limited preventive device was tested,such as mechanical properties test, electrical performance test, assessment test of dancing control effect, etc. The results of pilot application of position-limited preventive device verify that the newly proposed conductor's position-limited anti-galloping technology for overhead transmission lines can effectively enhance the anti-dancing capability of overhead transmission lines, and guarantee the safe operation of lines.
