Abstract

A musical scale type damping wire (2), used for preventing an overhead wire (3) in an overhead power transmission line from vibrating due to breezes. The musical scale type damping wire comprises lateral damping wire clamps (1) and musical scale damping wire clamps (4) respectively arranged on the overhead wire. The lateral damping wire clamps are fixedly arranged at two ends of the overhead wire respectively, the musical scale damping wire clamps are arranged between the lateral damping wire clamps at intervals, and damping wires are arranged between each lateral damping wire clamp and an adjacent musical scale damping wire clamp and between every two musical scale damping wire clamps respectively. The musical scale type damping wire stably holds a conductor, thereby avoiding the damage or strand breakage of the conductor due to an excessively high pressure, and can meet vibration control requirements on low, medium and high frequencies of a conductor / ground wire / optical fibre composite overhead ground wire OPGW in an over-35 kV power transmission line, in particular, in an ultra-high-voltage power transmission line. The vibration control coverage frequency is wide, the energy consumption effect is remarkable, and the vibration control effect is prominent.

Description

technical field [0001] The invention relates to a damping wire, in particular to a scale-type damping wire used for preventing overhead transmission line conductor / ground wire / OPGW breeze vibration. Background technique [0002] Breeze vibration is one of the important factors that threaten the safe operation of UHV transmission lines, and it is a problem that the line design, construction and operation management departments must attach great importance to. Long-term breeze vibration can easily lead to damage or even failure of each component of the transmission line (ground wire, hardware, etc.), which seriously threatens the safe operation of the transmission line. Therefore, effective measures must be taken to prevent and control the breeze vibration of the guide (ground) wire and the OPGW. The anti-vibration of guide (ground) wire and OPGW is usually realized by selecting and installing appropriate anti-vibration devices based on factors such as vibration form, occurre...
