Research and Validation on Melting Ice of Overhead Transmission Line

In order to further grasp the overhead rules of transmission line de-icing, this thesis designed and developed a newly transmission line icing apparatus, which can acquire the needed ice thickness covered upon a certain transmission line in laboratory. Combined with the walk-in temperature and humidity box, the temperature tester, current generator and other equipment, enhance the technology research capacity of overhead lines ice-melting. And the software can simulate the overlying ice temperature and cloud distribution changes with time, verify the line ice-melting rules. The method can be easily extended to other types of wires, and has certain application value.
