摘要

为解决机车牵引主电路的接地检测在运用过程中由于存在干扰而产生误报问题，对机车牵引传动系统主电路及接地检测回路原理进行了介绍，分析了主电路共模干扰对接地检测回路电压的影响，在此基础上提出了抑制接地检测回路共模电压的有效方法，通过仿真证明了理论分析的正确性，并在实际试验中进行了验证。

Abstract

The misinformation come up because of interference during operation of grounding detection for locomotive tractionmain circuit. The main circuit of locomotive traction system was introduced as well as the principles of grounding detection, and the effecton voltage of grounding detection loop caused by common mode interference in main circuits was analyzed. On the basis of the contentabove, the effective method of common mode interference suppression in grounding detection circuit loop was provided. In addition, thecorrectness of analysis was verified by simulation test and proved in experiments.
