Abstract

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.
