Power transmission line anti-icing apparatus based on electrothermal type hydrophobic material

The utility model provides a power transmission line anti-icing apparatus based on an electrothermal type hydrophobic material. The apparatus is arranged on a pole, a power transmission lead wire and an insulator of a power transmission line, wherein the insulator is fixedly connected with the power transmission lead wire. The apparatus is characterized in that the outer side of the power transmission lead wire is wrapped by a lead wire insulation layer, the lead wire insulation layer is externally wrapped by a first conductive coating for heating and melting ice, the insulator is covered by a second conductive coating, the power transmission lead wire is also provided with an equipotential point electrically connected to the first conductive coating, the first conductive coating and the second conductive coating are connected through a conductive flexible connecting wire, and the apparatus further comprises a gravity switch electrically connected with the second conductive coating and the pole under the gravity effect of ice. According to the utility model, whether the power transmission line is covered heavily by the ice can be accurately determined, the heat effect ice melting control mode is more accurate and reasonable, a series of complex, time-consuming and labor-consuming work including personnel real-time monitoring, wire inspection measurement, icing examination and the like are omitted, and the technical realization is more economic, simpler and more reliable.
