Multiphysics Arc Simulations of the Short-Circuit Interruption of a Miniature Circuit Breaker
Abstrak
The behavior of the electric arc that is ignited in a circuit breaker during a short-circuit is hard to predict, due to the involvement of several different physical phenomena; arc simulation tools are therefore necessary to be able to minimize the trial and error process during the design of a product. In this paper, we present results obtained using an arc simulation tool that implements fluid dynamics and electromagnetism together with metal and plastic ablation, taking also into account the dynamics of the moving parts; the tool also couples the simulated arc voltage to an electrical network to predict the influence of the arc on the short-circuit current.The comparison between the experimental and simulated arc voltages for different short-circuit performances of a miniature circuit breaker is shown, highlighting the key points of the modeling process (such as the mobile contact dynamics). The model is then used to investigate the contribution of the ablating materials to the pressure and the voltage.
