摘要
Abstract
Based on magnetohydrodynamics(MHD)theory,a 3D arc motion model for the dynamic breaking of contacts is established to simulate in the practical industrial products,making the simulation model closer to the real physical conditions of arc interruption.The arc motion process after interruption under different initial currents is analyzed.High-speed photography technology is used to carry out the relevant experiments.The comparison and verification with the simulation results fully demonstrate the effectiveness of the simulation model.Through the simulation study of arcs interruption under different currents,the location and causes of arc stagnation in the structure are pointed out,the reasons for the aggravation of arc stagnation during the interruption of large currents are analyzed,and the theoretical guidance is provided for the subsequent research and development of such products.关键词
