TQFR-3000型同步牵引发电机是东风_4型内燃机车的主发电机。其工作可靠性直接影响到机车的运行可靠性。在运行中发电机暴露出的惯性故障主要有三方面,下面谈谈我们针对这些问题所进行的结构、工艺改进。一、定子绕组短路前几年,由于定子绕组短路引起的发电机定子烧损是严重的,据1980年统计占发电机总故障的44%。
TQFR-3000 synchronous traction generator is the main generator of Dongfeng-4 diesel locomotive. The reliability of their work directly affects the operational reliability of the locomotive. There are mainly three aspects of the inertial failure exposed by the generator during operation. Next, we will talk about the structure and process improvement that we have conducted in response to these problems. First, the stator winding short circuit A few years ago, due to stator winding short circuit caused by the stator stator burn is serious, according to 1980 statistics accounted for 44% of the total generator fault.
