Problems solved by technology
High-voltage transmission lines usually use steel-cored aluminum stranded wires. In view of the material, thermal conductivity and heat capacity of the wires themselves, the high-current electrothermal ice-melting method consumes a lot of power, and also has non-negligible damage to the power generation side and transmission lines.
De-icing with a large span will cause jumping and galloping of the transmission line; in addition, due to the difference in the resistance and thermal resistance of the transmission line caused by the uneven material of the twisted wire and the difference in external weather conditions, the partial ice-melting effect is not good
Mechanical deicing is often easy to cause galloping and interphase flashover of transmission lines, which may cause more serious tower collapse accidents during deicing

Description
technical field [0001] The invention relates to a deicing tool, in particular to a deicing tool adapted to power transmission lines. Background technique [0002] In the cold winter, when the air humidity is high, the surface of the transmission line is prone to icing, and as the temperature continues to drop, the amount of icing on the surface of the transmission line will gradually increase, which will cause the weight load of the transmission line to increase. The bigger it is, it will even lead to severe consequences of the transmission line being broken and the tower collapsing. [0003] At present, there are two main deicing methods commonly used for transmission lines: one is the high current pulse deicing method, which melts the ice through electric heating; the other is the mechanical vibration deicing. High-voltage transmission lines usually use steel-cored aluminum stranded wires. In view of the material, thermal conductivity and heat capacity of the wires themse...
