The process of anode erosion has a significant impact on the interruption of high-current vacuum arcs. This paper seeks to theoretically explore the process of anode surface erosion caused by the combined influence of high-frequency inrush current energy flow density and arc pressure. Using a pure copper anode with a radius of 20mm, a model was established to study the erosion of the anode area under the influence of high-frequency inrush currents in a vacuum interrupter, using the equivalent arc energy of a standard high-frequency inrush current with an amplitude of 20 kA and a frequency of 4250 Hz within 2 ms as conditional input. Using the zero crossing point of the current as the zero moment. The results indicate that significant erosion occurs on the anode surface due to the combined effects of inrush energy flow density and the arc pressure generated by the high-frequency inrush current. After 0.3 ms of arc discharge, the temperature reaches the fusion temperature of the anode and forms a molten pool, and the liquid metal begins to flow. As a result, the peak temperature of an electrode surface did not remain at the center of an anode surface.
