摘　　要：在深入分析地面自动过分相基础上,提出一种改进的地面自动过分相方案—开关并联电阻地面自动过分相方案,并对该方案进行了基于Matlab/Simulink的仿真,研究表明,采用该方案能够有效地解决列车自动过分相时存在的暂态过电压问题。This paper analyzes the ground automatic passing the articulated phase insulator and brings a new method which is the automatic passing the articulated phase insulator with parallel resistance,Matlab/Simulink is used to simulate the process.The simulation results show that this new method can effectively restrain over-voltages in neutral sections when the electric locomotive passes the articulated phase insulator.
