    Abstract
  • The mathematical model of induced current for rail was deduced by using infinitesimal method.On the basis of the real-time synchronous testing data of the Da-Qin Railway, the formation mechanism, distribution characteristic, influencing factors of induced current and its influence on rail voltage were analyzed in detail.Computation result shows that the error of the model is less than 10% and it can satisfy the engineering data requirements.The farther the distance between locomotive and traction substation, the bigger induced current becomes, whose distribution is great in the middle and little at both ends.The bigger damping constant is, the bigger induced current becomes, the faster its saturated velocity is.Induced current has effect to reduce rail voltage.The farther the distance between locomotive and traction substation, the more obvious the effect becomes.With the increasing distance, induced current can reduce the voltage by 55% at current enter point.
