Description

Technical Field

[0001] The utility model belongs to the technical field of power transmission line monitoring, in particular to a sag dancing and tower base displacement monitoring system. Background Art

[0002] Due to freezing and windy weather, ice-covered transmission lines often dance in the wind. The dancing of ice-covered conductors poses a serious threat to the safe operation of transmission lines, and can easily cause phase-to-phase flashover, damage to hardware, line tripping and power outages, or cause serious accidents such as burning conductors, pulling down poles and breaking conductors, thereby causing significant economic losses, and causing the tower base to shift, which may cause sudden geological disasters such as tilting of the high-voltage tower base and landslides.

[0003] Traditional sag fluctuation and tower base displacement monitoring generally relies on manual visual observation of the fluctuation amplitude and frequency of the line and the displacement of the tower base to achieve the monitoring of sag fluctuation and tower base displacement. This not only wastes a lot of manpower and material resources for on-site monitoring, but also because of the low observation accuracy of the human eye, it is impossible to monitor and respond to sudden geological disasters such as high-voltage tower base tilting and landslides in real time, and may cause line tripping and power outages or cause serious accidents such as burning wires, pulling down towers and breaking wires, thereby affecting the safe operation of transmission lines and tower bases.
