摘　　要：通过研究一起发电机转子短路故障案例,从1000 MW汽轮发电机转子短路故障的报警开始,分析各项故障录波、跳闸曲线和相关试验数据,对转子故障点测算定位对拆出的相关部套件进行检查、验证,观察导电杆和导电杆绝缘板的故障现象,推测产生故障的原因,提出防范措施,为类似事件提出解决故障的思路和方案。By studying a case of generator rotor short-circuit fault,this paper starts with the alarm of short circuit fault in the rotor of a 1000 MW turbo-generator,and analyzes the fault recording wave,tripping curve and relevant test data,and then measures and locates the rotor fault point,checks and verifies the relevant parts and suites,observes the fault of conductive rod and insulation board,and speculates on the cause of the malfunction.Finally,the paper puts forward the preventive measures,and also offers the ideas and schemes to solve the fault for similar cases.
