Research and Application of DC Ice-Melting Technology for Overhead Transmission Lines

Ice disaster on overhead transmission lines is one of the main factors affecting the safe and stable operation of the power grid. With the application of rectification technology in the field of power transmission, DC ice melting method has gradually replaced manual, mechanical, and AC deicing methods with its advantages of safety and efficiency. This article mainly introduces the technical principles of DC ice melting, and uses actual cases to illustrate the calculation process of ice melting parameters.
