摘要

为解决地铁车辆牵引电机轴承电腐蚀问题，对其进行故障原理分析，提出并验证解决措施。首先指出轴承电压过高是导致电腐蚀的直接原因；其次结合地铁车辆牵引系统的特点建立了轴承电腐蚀高频等效电路，并对轴承电压的形成及部分影响因素进行了理论和试验分析；最后根据分析结果，对3种轴承电压抑制措施的有效性进行了验证。研究结果表明，改变牵引系统EMI电容对抑制轴承电压无显著效果，而降低整车保护接地电路高频电感、安装“接地环”可以有效抑制轴承电压，此外对安装“接地环”可能带来的风险也进行了探讨，并给出了风险评估方法。

Abstract

In order to solve the problem of electrocorrosion of traction motor bearings of metro vehicles, the fault mechanism was analyzed, and the solutions were put forward and verified. Firstly, it was pointed out that high bearing voltage was the direct cause of electrocorrosion; secondly, based on the characteristics of metro traction system, the high frequency equivalent circuit of bearing electrocorrosion was established, and the formation of bearing voltage and some influencing factors were analyzed theoretically and experimentally; finally, according to the analysis results, the effectiveness of three bearing voltage suppression measures was verified.The results showed that changing EMI capacitance of traction system had no significant effect on restraining bearing voltage, but reducing the value of high frequency inductance of grounding circuit and installing grounding ring could restrain bearing voltage effectively. In addition, the possible risk of installing grounding ring was discussed, and the risk assessment method was provided.
