Study on wind stability analysis and reinforcement measures of high-voltage transmission tower

Abstract Given that the high-voltage transmission tower is prone to collapse in windy weather, it is of great significance to study the wind stability analysis and reinforcement measures of the tower under the action of wind. In this paper, a 110 kV ZBC2-33 straight line tower is selected as the research object. The three-dimensional model of the tower is established by ANSYS, and the wind load of the tower is calculated. Then, the wind load is introduced into APDL, and the fixed constraint and wind load are applied to analyze the wind resistance stability of the tower. The displacement and stress distribution of the tower under wind load are obtained. Reinforcement measures are put forward for the weak parts and large deformation parts of the tower. Under windy conditions, the wind resistance stability of the unreinforced and reinforced transmission tower is compared and analyzed. By comparing the inclination of a transmission tower under different wind direction angles, it is shown that the reinforcement measures can effectively reduce the deformation degree of the transmission tower under the action of strong wind, but the improvement effect of different reinforcement measures on the inclination of the transmission tower is not the same. Among them, the effect of the main material reinforcement is better than that of the inclined material reinforcement. The results of this paper can provide a theoretical basis for the wind stability analysis and reinforcement measures of high-voltage transmission towers.
