摘要
讨论了地铁杂散电流电路元件模型特点,构建了基于电场的杂散电流模型,分析杂散电流的分布,估计其可能带来的危害,并以金属腐蚀量作为评估杂散电流危害的直观标准。通过编程对算例进行了求解和分析。
After discussing the features of stray current resistance components model, the author establishes the stray current model based on electric field to analyze the distribution of stray current in subway and the damages caused by it. The corrosion of metal is used as a visual standard to evaluate the harm of the stray current. In the endof the paper an example is given and it is solved by composing computer software
