摘　　要：某600 MW汽轮发电机机组大修期间,通过采用交流阻抗及损耗、两极电压平衡、绕组电压分布等方法,诊断出转子存在匝间短路故障,并判断出故障点位于上极绕组6号线圈。返厂解体证实上极绕组6号线圈存在匝间短路故障,修复后投入运行正常。During the overhaul of 600 MW steam turbine generator units,the inter-turn short-circuit fault in rotor is determined by AC impedance and loss,bipolar voltage balance and winding voltage distribution methods.Besides,it is determined that the fault is located in the sixth coil on upper polar.The disassembly demonstrates the fault,after repair of which the units return to normal operation.
