我段原配属东风机车18台,今年增加到35台,主要担当月山至洛阳、月山至晋城北间的货运和月山至长治北间的客运任务。经过几年的运用实践和段修质量的不断提高,ZQDR-410牵引电动机(简称410电机)的故障落修率不断有所下降。但是随着运用时间的增长和我段的具体情况,一些新的问题又暴露出来了。如主极C_2引出线的断裂,仅1982年1～10月份就出现6台次。其中造成临修4件。仅此一项故障,410电机的落修率就达到0.54台/十万公里,临修0.34件/十万公里。410电机主极C_2引出线断裂的部位如图1所示。
My original paragraph is Dongfeng Motor 18 units, this year increased to 35 units, mainly to take on the mountain from month to Luoyang, Yueshan to Jincheng north of the freight and the moon from the mountain to the north of Changzhi passenger task. After several years of practice and the continuous improvement of segment quality, the failure rate of ZQDR-410 traction motor (referred to as 410 motor) continues to decline. However, with the growth of the time of application and the specific circumstances of my paragraph, some new problems have been exposed. Such as the main pole C_2 pinout fracture, only from January to October 1982 there were 6 times. Which caused the temporary repair 4 pieces. Only this one fault, 410 motor fell to 0.54 units / 100,000 km, temporary repair 0.34 / 100,000 km. 410 motor main pole C_2 lead line broken parts shown in Figure 1.
