On-line monitoring analysis of Aeolian vibration of Songhua River longspan of Yongyuan-Xingfu 550 kV transmission line

With the rapid development of electricity industry,the adoption of bundle conductor,high-capacity and long-distance transmission lines have become inevitable. Aeolian is a risky problem of overhead transmission lines due to the conductor wire broken off sometimes for it. This paper introduces the design of on-line monitoring equipment for Songhua River long span of Yongyuan-Xingfu 550 kV transmission line. Research on fatigue property,aeolian vibration performance,anti-vibration method,which will be significant to assure transmission lines safety.
