摘要
为优化直流转换开关结构,增强直流转换开关的直流电流转换能力,针对不同的喷口截面积进行空载气流场的仿真分析。根据仿真结果设计了两种直流转换开关的喷口结构,并以低频振荡回路模拟直流电流进行直流转换开关的电流转换试验研究。试验情况与仿真结果相吻合,验证了气流场计算的正确性,为直流转换开关的优化设计提供了指导。
In order to optimize the structure of the DC transfer switch and enhance current commutation capabilityof the DC transfer switch, the simulation of no-load flow field have been made for different nozzle cross-sectionalarea. According to the simulation results, two structures of DC transfer switch nozzle have been designed, and theexperimental study of current commutation is carried out by using low-frequency oscillation circuit analogue DCcurrent. Test cases are almost as same as the simulation results ,the correctness of the flow field calculation isverified and the guidance of DC transfer switch design is provided.
