摘要
Abstract
Based on the over-voltage waveforms measured in phase-separating section when the locomotives passing,the equivalent electrical parameters and mathematical model of contact net are researched.This paper proposes switch-ground＇s auto-passing neutral section to use power electronic switch.It could eliminate the over-voltage in the neutral section,meanwhile locomotives could pass the neutral section with load（not open the main circuit break）.It is analyzed theoretically that overvoltage occurres when switches cut-off and cut-in.The simulation results show that the theoretical analysis is effective.关键词
