摘要:
接地方式的优劣直接关系到地铁车辆运行性能的好坏，其研究具有重要意义。文章介绍了保护性接地、功能性接地和电磁兼容相关接地的分类和定义。使用电路仿真和电路分析的方法分析了不同拓扑方案的优势和劣势，以及不同拓扑方式对车体回流和EMC性能的影响，并推荐使用具有接地电阻解耦功能的车辆接地方式。在设备级接地方面，比较了单点接地和多点接地的优缺点，并推荐使用多点接地方式。
Abstract:
The function of the grounding system is related to the operation performance of the metro vehicles, so it has special significance to conduct a research. The classification and definition of the vehicle grounding was introduced, including protective earthing, functional bonding and EMC-related grounding. The advantage and disadvantage of different earthing topology forms and the influence to the carbody current and EMC were analyzed by the circuit simulation and analysis methods, and vehicle grounding mode with grounding resistance decoupling function was recommended. For systems grounding, by comparing two different earthing methods of single-point and multiple-point, the latter was recommended.
