HXD3C型机车无火回送故障现象及改进措施

No-fire Feedback Fault Phenomenon and Improvement Measures of HXD3C Electric Locomotive

通过对HXD3C型电力机车制动控制原理的分析,判断机车进行无火回送试验时发生列车管制动减压后无法保压故障的原因,并针对原因提出了可行的解决方案。

Based on the analysis of the braking control principle of HXD3C electric locomotive,the reasons for the failure to maintain the pressure after the dynamic and decompression of the train control during the locomotive no-fire feedback test are determined,and the feasible solutions are proposed.
