摘　　要：燃气轮机在起动过程中出现了自动停车,经排故检查发现为转速传感器故障。对转速传感器的结构和工作原理进行了深入分析,通过炭化方法找到了故障点,确定为内部断路故障,并针对该故障类型制订了纠正措施,从根本上杜绝了故障再次发生。Automatic stopping appeared in the starting process of the gas turbine, and it is found that there is speed sensor fault after troubleshooting inspection.Structure and operating principle of the speed sensor are deeply analyzed, and the point of failure is found by charring method to determine the internal circuit failure, and then the corrective action for the type of fault is developed, so as to eliminate the fault occurs again radically.

关 键 词：燃气轮机 转速传感器 失效分析
