对东风_4内燃机车牵引电动机的故障与可靠性,大家谈论得比较多,而对TQFR-3000主发电机(以下简称主发电机)的故障与可靠性,相对说来,则谈论得较少。但从厂修中暴露出来的问题看,主发电机的故障也较多,特别是定子方面的故障,更为突出。而且定子方面一旦发生故障后,一般说来,机务段都不具备修复条件,必须送工厂进行修理。所以,不但影响机车的运行可靠性,而且造成的经济损失也较大,因此,对主发电机,特别是对主发电机定子方面的故障与可靠性进行研究和探讨,是非常必要的,应该引起大家足够的重视和注
On the Dongfeng _4 diesel locomotive traction motor fault and reliability, we talk about more, and TQFR-3000 main generator (hereinafter referred to as the main generator) fault and reliability, the relatively speaking, less talked about . But from the factory repair problems exposed, the main generator fault is also more, especially the stator fault, even more prominent. And in the event of stator failure, in general, the locomotive depot does not have the conditions for repair, must be sent to the factory for repair. Therefore, not only the operation reliability of the locomotive is affected, but also the economic loss caused by the locomotive is also large. Therefore, it is necessary to study and discuss the faults and the reliability of the main generator, especially the stator of the main generator, which should be Aroused enough attention and attention
