Problems solved by technology

[0003] At present, the monitoring of transmission poles and towers mainly depends on the regular inspections of line inspectors, but the inspections of inspectors cannot achieve real-time monitoring, and it is difficult for line inspectors to detect subtle vibration changes of towers, which leads to serious damage to power transmission. Tower vibration monitoring is not efficient and accurate enough

Description

technical field [0001] The invention relates to the technical field of power transmission line monitoring, in particular to a vibration monitoring terminal for power transmission poles and towers. Background technique [0002] Transmission towers are important facilities for transmission lines, and long-distance transmission of high-voltage transmission lines requires the erection of corresponding transmission towers. After the transmission pole tower is erected, it will bear various static loads such as the tension and gravity of the ground wire, the gravity of the insulator string fittings, and the self-weight of the tower body. , The whole or part of the transmission tower will vibrate. The vibration will lead to fatigue damage of the tower material, tearing of the bolt holes, loosening or even falling off of the node bolts, which reduces the load-bearing performance of the tower. It will cause local damage to the transmission tower, and it will cause the entire tower to ...
