Research on Mode-Switchover Process and Protective Circuit of Dual Power Supply System for Regional Express Electric Multiple Unit

摘要

This paper firstly puts forward the integrated traction equipment proposal of dual power supply system. Then it analyzes the catenary-pantograph relationship, the mode-switchover process and the risk of incorrect connection between the main circuit and power, then taking these as a measure, assesses the current collection and protective proposal according to the economic and industrial factors etc. Finally, on the basis of it, the preferred proposal is given.
