| Abstract: | According to the problem of main switch automatic tripping on CRH5A train,the voltage and electricity at relevant test points are analyzed,the voltage abnormal point when the fault happens is detected,and the main reason for automatic tripping is confirmed.Then,corresponding measures are taken,such as the adjustment of the pantograph in certain sections.This research helps to solve the tripping problems and eliminate main switch faults. |
