Background
Overhead transmission lines under extreme climatic conditions, in particular overhead transmission lines in some alpine mountain areas of China, are often severely iced in winter. There is less ice coating on the wire and more ice coating on the ground wire. Longitudinal unbalanced tension generated by uneven ice coating on the conducting wire and the ground wire can cause the iron tower to incline or bend towards the side with large tension, when the design bearing capacity is exceeded, the conditions of breakage of the conducting wire and the ground wire, dropping of hardware fittings and the like can occur, and the iron tower can collapse in severe cases. In addition, since overhead ground wires do not resist partial freezing unlike conductors that can withstand the heat generated by the load current, the thickness of the ice coating is typically much greater than that of power transmission conductors. In order to improve the ice disaster prevention capability of a power grid, the development of the ground wire ice melting device has important practical significance.
In the design of the whole ice melting device, how to connect the current of the lead into the ground wire is a more critical step, in the existing ice melting device, the conducting rod is usually designed into a long straight rod structure, the length is generally 5m-8m, and conducting rods with different lengths are required to be used for different tower shapes, so that the conducting rod with the structure has no universality. In conclusion, the conducting rod is indispensable in the whole device as a structure for connecting the current of the conducting wire into the ground wire, but the existing conducting rod has the defects of long length and large volume, does not have universality, and is difficult to meet the requirements of the existing ice melting device.
