摘　　要：厦门地铁1号线自2023年以来发生多起牵引逆变器模块IGBT失效故障,结合故障发生时刻、故障分布位置,从工作环境湿度、散热等方面对造成失效的原因进行了分析,并制定了相应的解决措施。运用结果表明,整改措施有效解决了牵引逆变器模块IGBT故障率高的情况,为后续IGBT维修策略制定提供了依据。Since 2023,multiple IGBT failures have occurred in the traction inverter modules of Xiamen Metro Line 1.Based on the time of occurrence and location of the fault,Analyzed the working environment humidity,external fan working strategy,and thermal conductive silicone grease,among other aspects,and corresponding solutions have been formulated.The results indicate that the rectification measures have effectively solved the high failure rate of IGBT,and providing a basis for the formulation of subsequent IGBT maintenance strategies.
