Eccentric Force Analysis Of Transmission Tower Angles Under Ice-covered Environment

As one of the important disasters of transmission lines, the deformation and instability of the main angles of transmission towers under ice-covered environment is the key to the performance of the bearing capacity of such components. This paper adopts finite element software to establish 500kV “resistant-straight-resistant” tension-resistant section tower line model, analyzes the force situation of the tower under different ice-covering conditions, and obtains the force characteristic curve of the tower angle under ice-covering conditions, and adopts three-dimensional modeling software to establish a detailed simulation model at the nodes of the angle steel, and analyzes the pressure process of the main angle steel in the tower by means of finite element analysis, and then analyzes the deformation and instability of the main angle steel in the tower. The simulation analysis is carried out by finite element analysis method, and the mechanical characteristics of the eccentric force of the main angle in the tower under ice-covering environment are obtained.
