By studying the magnetization mechanism of the DC cable to the steel plate and the simulation of the remanence of the steel plate,a typical ferromagnetic structure model is established,and the magnetization of the steel plate is verified by a large DC current.The experimental results are basically consistent with the simulation.Combining the power supply characteristics of all-electric propulsion ships and the requirements of magnetic protection,an optimized design plan for cable laying is proposed.
