CI作为主变换装置中牵引传动系统的主要部件,性能质量是安全运营的关键点。在对设备进行检修时,必须对牵引变流器发生的故障进行分析、记录,深入分析原因和方法,提出了以变流器输出电流作为故障特征参数的方法,提高故障判断处理的效率,已达到提高运营管理的目的。 As the main component of the traction drive system in the main conversion unit, CI is the key point in the safe operation of performance quality. In the maintenance of the equipment, it is necessary to analyze the fault occurred in the traction converter, record and analyze the causes and methods in-depth, and put forward the method of using the converter output current as the fault characteristic parameter to improve the efficiency of the fault judgment process. To achieve the purpose of improving operations management.
