- Transmission line icing coating will lead to ice shedding when ambient temperature rises or the wind increases. It can cause serious security threat to the structure of the transmission line system. In the paper, based on the Lagrange Equation, the analytical dynamics equations of transmission lines ice shedding are deduced in theory. In these equations we comprehensively consider the factors affecting the dynamic characteristics of the ice shedding and do quantitative analysis. Taking a certain transmission line as an example, considering three kinds of working condition of ice shedding , our system analyzes the effect of ice shedding position and ice shedding proportion on the dynamic characteristics of a transmission line. Therefore we obtain a deeper understanding of problems of transmission lines ice shedding. The paper puts forward the method of important engineering value that could be used to direct line maintenance and design and guarantee the safe operation of the transmission line.
