| 摘 要： | 轨道交通目前已成为人们出行的主要方式之一，但在轨道交通车辆运行环境内，除了列车的电气设备，还存在无线发射站等多种无线电磁干扰源。在复杂电磁环境下解决轨道交通的电磁兼容问题（即电磁干扰和电磁抗扰问题）是保证轨道交通安全的关键。为了解决这个问题，本文对轨道交通车辆的抗电磁干扰能力进行研究。首先，分析轨道交通车辆的电磁干扰问题，并提出了抗电磁干扰的两个解决途径。其次，从接地、滤波、屏蔽、布线和电子元器件选择等5个方面给出了对应的抗电磁干扰设计方法，并从系统级和整车两个维度出发，针对具体设备、组件和整车提出了具体抗电磁干扰设计方法。最后，结合温州市域S1线项目，通过轨道交通车辆抗电磁干扰现场试验，验证了所提抗电磁干扰设计方法的合理性和有效性。

| Abstract: | At present, rail transit has become one of the main ways for people to travel. However, in its operating environment, electromagnetic interference is generated by a variety of the electrical equipment of the train, and wireless electromagnetic interference sources. Solving the electromagnetic compatibility (EMC) problem of rail transit in the complex electromagnetic environment is key to ensure their safety. To solve this problem, the ability of anti-electromagnetic interference of rail transit was studied in this paper. First, electromagnetic interference problem and its solutions were presented. Second, from the aspects of grounding, filtering, shielding, wiring, and the choice of electronic components, the anti-electromagnetic interference methods were proposed. And based on these principles, from two dimensions of the vehicle and equipment level, the detailed anti-electromagnetic interference design methods of rail transit were proposed for specific equipment, components and entire vehicles. Finally, taking Wenzhou City Line S1 Project as examples, the rationality and effectiveness of the proposed anti-electromagnetic interference design methods were verified through the field test. |
