摘要
分析了走行轨为回流的供电系统产生的杂散电流分布规律,推导出杂散电流总量工程计算方法和容许值,同时分析了各种杂散防护措施与总量关系。
This paper analyzes the distribution regularity of the stray current generated by power-supply systems whose running rails are for the current return as well as the relationship between the amount and various protective measures.Meanwhile the engineering calculation method of stray current＇s totals and allowable value are deduced.
