Description

technical field [0001] The invention relates to the technical field of transmission line detection, in particular to a wire galloping amplitude monitoring system based on microwave interference technology. Background technique [0002] With the development of society and economy, more and more high-voltage transmission lines are gradually being surveyed, designed and constructed. Most of the high-voltage transmission lines are operated in the field and have been tested by harsh conditions for a long time. For many years, coastal areas have been severely damaged by typhoons. Line failures caused by typhoon disasters have accounted for more than 30% of the total trips. , causing accidents such as disconnection, flashover, and tower collapse, which brought major economic losses to the local power sector. In order to accurately monitor the towers and conductors of transmission lines, it is very important to help the power sector to find hidden dangers, troubleshoot faults, and ...

AI Technical Summary

Problems solved by technology

[0004] (1) High construction cost

The point-by-point measurement deformation monitoring system needs to densely deploy sensors when monitoring large towers, and the workload in the field is heavy, resulting in high system costs and slow measurement speeds;

[0005] (2) Low degree of intelligence

System construction is time-consuming, and it will take a lot of time and cost to detect and repair damaged devices during operation;

[0006] (3) Low ability to work around the clock

However, laser equipment is as susceptible to environmental interference as measuring robots during long-distance measurement, and the current laser deflection meters are all point light source products, which are extremely expensive for multi-point measurement, and are not currently suitable for long-term monitoring.

High-definition cameras are easily affected by the weather, and are easily disturbed in poor light or rainy and snowy weather, making it difficult to achieve real-time monitoring throughout the day
