摘要

直流牵引供电系统中,排流装置投入后究竟是改善还是恶化杂散电流一直饱受争议。为此,该文建立了考虑排流装置的钢轨回流系统模型,并结合叠加原理推广应用于多牵引变电所时的杂散电流与钢轨电位计算。通过CDEGS仿真和排流装置的投退实验验证了模型在计算杂散电流和钢轨电位方面的准确性。并在此基础上,分析了一次杂散电流和排流网收集杂散电流效率的影响因素。研究结果表明,国内轨道交通工程排流网收集杂散电流的效率偏低,排流装置投入后,一次杂散电流增大为未排流的4.87倍、5.34倍,二次杂散电流增大为未排流时的5.41倍和 4.63倍。

Abstract：

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.

Key words： DC traction power supply system stray current drainage device drainage net
