| 中文摘要: |
| 针对铁路机务部门,为了实现利用车载DC110V电源对机车牵引电机进行快速、准确的检测,判断出故障源并及时的排除故障,保证机车车辆的通畅运营。通过对交流牵引电机的故障机理和诊断方法的研究,提出了一种通过单片机对牵引电机响应电流上升时间的测取来判断交流牵引电机绕组绝缘状态的检测方法。并通过对脉冲变压器的设计,来满足不同的牵引电机对检测电压的要求。从而达到减少铁路机务部门相关人员的工作强度。 |
| 英文摘要: |
| This paper aims at quick and accurate detection of locomotive traction motors by using on-board DC110V power supply in the railway locomotive department to determine and remove the fault in time to ensure smooth operation of rolling stock. Based on the study of the fault mechanism and diagnosis method of AC traction motors, this paper presents a detection method for judging the insulation state of the AC traction motor winding by using the single-chip to measure the rise time of the response current of the traction motor. Furthermore, pulse transformers are so designed as to meet the requirements of different traction motors on detection voltage. In this way, work intensity of relevant personnel is reduced in the railway locomotive department. |
