Calculation of Ice Thickness Based on Force Analysis of Transmission Lines
The present work establishes a new calculation method through force analysis of overhead transmission lines and tower systems.Using the mechanical standard equation of overhead transmission lines,parameters such as inclination angle,wind deflection angle,and tension measurement values at the suspension point of the cable are substituted into the equation as initial parameters,and iterative calculations are carried out for successive approximations.Finally the equiva-lent icing thickness of the cable is converted.This calculation method utilizes the comprehensive effect of various mechani-cal parameters to accurately estimate icing thickness of the cable.The established mechanical model is verified by case a-nalysis to have small deviation and satisfactory reliability and accuracy.
