Abstract

Abstract: High voltage transmission line icing has a serious threat to the safe operation of power grids, electric ice melting is a complex multi-physics nonlinear process. This paper reveals the mechanism of ice melting in theory by full method, analyzes the ice melting time of LGJ-70/10 and LGJ-400/65 type wires under different boundary conditions, and proposes the important parameters of ice melting in shortest time which is related to the ice melting efficiency, the security of transmission lines and energy saving needed to consider in the field of electric melting technology, summarizes the influence of the ice thickness, ice temperature, the conductor temperature, environment temperature, and convection load on the shortest ice melting time, which will provide a reliable theoretic basis for ice melting technology of high voltage transmission lines.

Key words: high voltage, transmission line, full method, electric ice melting, ice melting time
