我段自1982年起,先后采用了上海铁道学院研制的TZ型接触电阻检测仪、TY型直流耐压检测仪和匝间耐压检测仪,对电力机车电机、电器、变压器等设备进行了检测与试验。实践表明这些仪器的推广使用对提高电力机车的运行可靠性是有明显效果的。 1.TZ型接触电阻检测仪的应用 (1)使用这种仪器测量ZQ650-1牵引电动机轴与轴承内套的配合是行之有效的,我段已于1983年把它正式编入了检修工艺。目前,我段已对十多台架修机车电机和备用电机共70余台计140个轴承内套与轴的配合进行了测量,
I paragraph since 1982, has adopted the TZ contact resistance tester developed by Shanghai Railway Institute, TY DC voltage tester and turn-on voltage tester, the electric locomotive motors, appliances, transformers and other equipment were tested And experiment. Practice shows that the promotion of the use of these instruments to improve the reliability of electric locomotives have a significant effect. 1.TZ contact resistance detector application (1) The use of this instrument to measure ZQ650-1 traction motor shaft and bearing inner sleeve with the cooperation is effective, I paragraph it was formally incorporated into the maintenance process in 1983 . At present, I have more than 10 pieces of chassis repair motor locomotive and spare motor total of more than 70 sets of 140 bearing inner sleeve and shaft with the measurement,
