直线电机(LIM)车辆在广州地铁运用以来,列车直线电机多次出现烧损、槽楔下沉以及绝缘电阻过低的故障。分析了广州地铁4号线车辆直线电机典型故障案例,探讨了直线电机运行过程中的一些常见故障原因,提出了提高直线电机运行可靠性的措施。
Linear motor (LIM) vehicles used in Guangzhou Metro since the train several linear motor burning, wedge sinking and insulation resistance is too low fault. The typical failure cases of linear motor in Guangzhou Metro Line 4 are analyzed. Some common causes of failure during the operation of linear motor are discussed. The measures to improve the reliability of linear motor are put forward.
