Abstract

In order to optimize the structure of the DC transfer switch and enhance current commutation capability of the DC transfer switch

the simulation of no-load flow field have been made for different nozzle cross-sectional area. According to the simulation results

two structures of DC transfer switch nozzle have been designed

and the experimental study of current commutation is carried out by using low-frequency oscillation circuit analogue DC current. Test cases are almost as same as the simulation results

the correctness of the flow field calculation is verified and the guidance of DC transfer switch design is provided.
