摘要
根据井下直流机车回流通路的特点,建立了杂散电流传输网络有限单元模型,提出了直流杂散电流和接触电压分布的数值计算模型;结合仿真计算的结果,对影响杂散电流和接触电压分布的参数进行了比较和讨论,为系统设计提供了理论基础。
Based on the characteristics of the DC traction power system in the mine, finite cell model of the DC transmission net was established, and a numerical model of calculating DC stray current and potential variation distribution was put forward. As to the results of simulation, compared and discussed the parameters that effect stray current and potential variation distribution, and proposed the theory basement for the system design.
