The icing disaster of the overhead ground wire seriously affects the safe and stable operation of the power grid system. Compared with the traditional thermal ice melting technology, the mechanical de-icing technology has obvious advantages such as stable and reliable operation, low equipment cost, simple operation and low energy consumption in the application of overhead ground wire de-icing, and has become one of the necessary de-icing methods of the power grid. Based on the principle and electrodynamic characteristics of electro-impulse de-icing of overhead ground wire, this paper calculates the optimal winding form of pulse coil through electromagnetic mechanics simulation. Through icing in artificial climate chamber, the electromagnetic pulse de-icing test of wire is carried out, and the de-icing performance of electro-impulse de-icing device is analyzed. The comprehensive adaptation test analysis of the de-icing device is carried out to study its fatigue characteristics and electromagnetic interference characteristics. The test results have important reference value for the research on the electromagnetic pulse de-icing technology of overhead ground wires and the design of the device.
