Research on De-icing Tests of Overhead Transmission Lines

With a wide range of the grid icing disasters,it becomes urgent to master the key de-icing technology.However,how to obtain the controllable de-icing thickness upon a certain transmission line in the scope of a laboratory has become the primary constraint for de-icing technology development.A self-developed transmission line icing apparatus can efficiently solve the problem.By applying the de-icing system in the laboratory,the de-icing effects are analyzed through the simulation of various de-icing conditions.It can serve as a reference for on-site de-icing operation.
