| Abstract: | With the application of MV DC electric power system in the marine, the calculation and design of MV DC switch board arc resistance becomes to an urgent problem. This article focused on the structure of MV DC switch board, analyzed the arc physical process, proposed and adopted CFD method to modelling and simulate, the accuracy is substantially improved than the calculation method based on gas equilibrium of the past. By analyzing the calculation result and error sources, provided the conclusion of the optimization design scheme for MV DC switch board, and looked forward to the coupling simulation method in the future. |
