Resumen
The paper derives the current-voltage relationship in the semiconductor circuit breaker based on the equation of fluidmechanics which has application for safe and water access. Then, the paper proposes a Newton iterative method basedon the finite element analysis method to solve the nonlinear algebraic equation relationship in the semiconductor circuitbreaker. At the same time, the paper constructed a coupled numerical model based on the hydrodynamic equations andapplied it to the pulse current prediction. Experiments have proved that the algorithm can realize large-scale open-circuitswitching current forecast, and the algorithm has high efficiency and accuracy.
