Abstract
In order to solve the problem that the overhead ground wire ice-melting needs power outage operation,this paper takes two parallel optical fiber composite overhead ground wires(OPGW)and Al-cladding steel strands as the research objects,and proposes a new method of energized DC ice-melting for overhead ground wires.Firstly,the composition principle of the ice-melting circuit in this method is studied in depth.Then,the simulation model of the ice-melting circuit is established by using ATP-EMTP software,and the ice-melting current and the capacity of the ice-melting power supply are calculated.Finally,the ice-melting process of OPGW and Al-cladding steel strand and the temperature distribution of OPGW after de-icing are simulated and analyzed by COMSOL software.The research show that when the ice-melting power supply is installed in the middle of the ice-melting section,two parallel ground wires can deice at the same time;the influence of DC current in the ice-melting section on the non-ice-melting section is very small and can be ignored.关键词
