Problems solved by technology

The current simulation method of the magnetic field inside the vacuum interrupter is to establish a model in the simulation software. Once some parameters of the interrupter (such as contact distance, contact shape and structure) are studied due to design requirements Due to the influence of the internal magnetic field distribution, it is necessary to continuously change the parameters of the simulation model, so the model can only be rebuilt continuously, which affects the problem of prolonging the design cycle of the arc extinguishing chamber
