| 摘 要： | 随着电力机车牵引电流不断增大,钢轨电位过高成为突出问题.本文通过建立直供方式下钢轨电位的分布参数模型,并用MATLAB进行仿真,得出了钢轨上电位和电流的分布情况.分析了主要参数对钢轨电位分布的影响;考虑机车本身的影响,引入了机车系数来修正钢轨电位峰值.最后给出了在通常情况下钢轨电位计算值和实际值的比较,验证了模型的正确性.

| Abstract: | With the traction current of electric locomotive increasing,the rise of rail potential becomes a considered problem.In this paper,based on the establishment of rail potential distribution model and the simulation used MATLAB,the potential and current distribution on the rail are depicted.The main parameters and other factors affecting the rail potential distribution are also discussed.The train factor was introduced to amend the peak of the rail potential.Finally,the calculated data of the rail potential under normal circumstances is compared with the actual data to verify the correctness of the model. |
