| Abstract: | This paper introduces the influence of aeolian vibration on the safe operation of overhead transmission line,especially longspan,expounds the arrangement of on-line monitoring equipment for Songhua River longspan of Hegang-Mulan 220 kV transmission line,analyzes the data acquired by on-line monitor and advises operation department on the basis of the data to tighten the clamped points of longspan conducting wire,ground wire,damping line and damper,which prevents the breakage of conducting and ground wire due to grip relaxation caused by creep deformation. |
