东风_4型机车主发电机大线原为每相4条,因发热老化、龟裂等问题。现改为每相6条。改后的大线已经在客运机车上取得了明显效果,但在货运机车中,大线的发热、龟裂、端子过热、氧化、烧损等问题,在我段仍十分严重。 (一)我段机车运用情况介绍我段自1983年7月投产以来,主要担当济(南)德(州),济(南)兖(州)间直货运输任务。其中济兖间下行定轴3500吨。在1983年7月以前,因其中的72公里长的济(南)泰
Dongfeng _4 locomotive main generator line was originally four per phase, due to heat aging, cracking and other issues. Now changed to 6 per phase. The modified line has achieved remarkable results in passenger locomotives. However, in freight locomotives, the problems of heating, cracking, overheating of terminals, oxidation and burning in large locomotives are still very serious in our section. (I) Introduction of Locomotive Usage in I Section Since the commissioning in July 1983, I have been mainly responsible for the direct cargo transport between Jinan (South) Dezhou and Jinan (South) Yanzhou (State). Among them Yanzhou between the downlink axis 3500 tons. Before July 1983, due to one of the 72 kilometers of economic (South) Thailand
