Design Analysis of Overhead Transmission Lines Based on Wire Model and Isolated Span Calculation
In response to the problems of insufficient stability and safety in traditional overhead transmission line design,a design method for overhead transmission lines based on wire model and isolated span calculation is studied and designed.Firstly,parameters such as sag and stress are calculated using wire model,and then calibrated using isolated span calculation.The results show that when using the design method,the maximum sag on different gantry sides can reach 0.95 m,and the maximum sag on the entry line on different gantry sides can reach 2.02 m,indicating that the design method can effectively improve the stability of overhead transmission lines.The effectiveness of the design method has been proven,and it has important practical significance in ensuring the safe and stable operation of the power system.
