Problems solved by technology

[0005] The current simulation method of the temperature field inside the vacuum interrupter is to establish a model in the simulation software. Once some parameters of the interrupter (such as the radius and height of the conductive bridge) are studied due to design requirements, the temperature field inside the interrupter will be affected. The influence of the distribution, so that the simulation model parameters need to be continuously changed, and the model can only be rebuilt continuously, so that the design cycle of the arc extinguishing chamber is prolonged
