In the DC traction power supply system, whether the stray current is improved or worsened after the drain device is put into use has always been controversial. Therefore, this paper establishes a rail reflux system model considering the drainage device, and applies it to the calculation of stray current and rail potential in multi-traction substations combined with the superposition principle. The accuracy of the model in calculating the stray current and rail potential is verified by CDEGS simulation and the drop-out experiment of the drain device. On this basis, the influence factors of the primary stray current and the efficiency of collecting stray current in the drainage net are analyzed. The results show that the efficiency of collecting stray current by the drainage net of domestic rail transit projects is relatively low. After the drainage device is put into operation, the primary stray current increases by 4.87 times and 5.34 times, and the secondary stray current increases by 5.41 times and 4.63 times.
