TQFR-3000主发电机(简称主发电机)是东风_4机车的主要部件之一。它一旦发生故障,危害大,修程大,经济损失也大。因此,对主发电机故障的预防性修理就更具有重要意义。经过几年对主发电机的攻关改造,运用可靠性有了很大的提高。特别是转子磁极联线改造后,联线的断裂故障得到了控制,相对来说,定子故障就显得较为突出。这里所说的定子故障主要是早期(1974～1979年)主发电机定子故障。几年来,我们对定子故
TQFR-3000 main generator (referred to as the main generator) is one of the main components of Dongfeng _4 locomotive. Once it breaks down, the damage is big, the repair is big, and the economic loss is also big. Therefore, the preventive maintenance of the main generator failure is even more important. After several years of renovation of the main generator, the reliability of application has been greatly improved. Especially after the transformation of the rotor pole connection, the fault of the connection line has been controlled. In contrast, the fault of the stator becomes more prominent. Stator fault here is mainly the early (1974 ~ 1979) the main generator stator fault. In recent years, we are the stator
