Dual-current-type electric traction mode represents the development direction of interconnection between urban rail transit and trans-urban railroad,and has broad applicative prospect.The railway depots in dual-current-type electric traction systems need to realize the function of AC/DC power supply switching.This leads to,inside the depots,dense rails,closely located contact networks,and AC/DC hybridization of contact networks,and furthermore,more complex e-lectrical environments.In order to facilitate safe maintenance of the railway depots,this work established the vehicle-net-work-ground coupling model of railway depot,analyzed the distribution law of the rail potential and the influencing fac-tors,and quantitatively evaluates the safety of internal traction return current.
