The Numerical Research on the Jumping Induced by the Uniform and Non-Uniform Ice-Shedding of Transmission Lines

Abstract:

This paper introduces several kinds of icing and ice-off simulation method: the equivalent load method, quality method, Támás model method and cell death method. With a large span cross section as an example, using finite element method, established the finite element model of single span icing wire, analyzed the non-uniform ice-off and the even ice-off,the results show that: Non-uniform ice-off dynamic tension is significantly smaller than even ice-off dynamic tension,the smallest dynamic tension is closely related to wire jump amplitude, the greater jump amplitude leads to the smaller dynamic tension,the essence of which is determined by the conductor slack.
