Failure Analysis and Solutions of Tram Ground Power Supply Module Based on Force Field Principle
Aiming at the frequent failure of the positive copper sheet burning problems in the ground power supply module of tram based on the force field principle,the electrical characteristics of copper sheet at the working moment are mastered by testing its working state.With load capacity analysis of the copper sheet,it is pointed out that the arc caused by capacitive current,and the unbalanced current between two pantographs are the rootcauses of the copper sheet's burning fault.Through the targeted measures,the fault has been eliminated.
