| 摘 要： | 电力机车通过关节式电分相时，多次发生过电压现象，导致牵引变电所跳闸，对接触网和牵引变电所的安全运行构成严重影响。本文基于MATLAB／Simulink仿真软件对电力机车通过关节式电分相的过程进行仿真分析，针对中性段产生过电压的原因提出了一种抑制过电压的保护方案。

| Abstract: | Over-voltages frequently happen when the electric locomotive passes the articulated phase insulator, which causes tripping of substations and serious influence on safe operations of the overhead contact system and traction substations. In this paper, the MATLAB/Simulink are used to simulate the process of the electric locomotive passing the articulated phase insulator, the causes of generating over-voltages in neutral section are analyzed, and measures for suppressing over-voltages are put forward. |
