Research on measuring point layout and stress monitoring method of transmission tower

Transmission towers are the most important power equipment in transmission lines, and monitoring the structural safety of transmission towers is of great significance. A three-dimensional finite element model of 66kV drum-type tower was established and the static strength of the drum-type tower under wind load was analyzed. It is indicated that the maximum stress of the drum-type tower tower under wind load is much greater than that under gravity load only. Based on the simulation results of the maximum stress location, the optimal layout method of stress sensors was obtained, and a stress monitoring system for transmission towers was designed.
