摘　　要：分析动车组低速出入动车运用所(库)通过绝缘关节时的燃弧过程,通过建立等效模型并借助Simulink仿真平台,仿真分析了不同网压差对绝缘关节电位差、牵引网暂态过电压的影响。研究结果表明,燃弧与两侧网压差、动车组运行速度及锚段关节设计有关。By analyzing the arcing process under passing through the insulated overlap section by EMU in a low speed as it enters into or departs from the EMU operation deport（shed）, and by means of establishing the equivalent model, being assisted with Simulink simulation platform, the influences to the insulated potential difference and traction network transient over-voltage caused by different network potential differences are simulated and analyzed. The researching results show that the arcing relates to the network potential differences at both sides of network, running speed of EMU and design of overlap section.
