摘　　要：传统重复脉冲法检测技术在发电机转子匝间短路检测中得以广泛推广及应用,但其单一诊断技术也对试验结果造成了一定的局限性,甚至会因误诊断扩大检修范围,严重影响大修工期及机组维护成本。为此,介绍了增强型重复脉冲法。作为一种组合型检测技术,其通过多电压等级、多试验方法综合考量试验结果,提升了检测精度,对发电机转子诊断结果具有实际参考意义。The traditional repetitive surge oscilloscope technology has been widely popularized and applied in the detection of generator rotor turn to turn short circuit,but its single diagnosis technology has also caused certain limitations to the test results,and even expanded the maintenance scope due to its misdiagnosis,which has seriously affected the overhaul period and unit maintenance cost.The enhanced repetitive surge method is introduced.As a combined detection technology,it comprehensively considers the test results through multiple voltage levels and multiple test methods,improves the detection accuracy,and has practical reference significance for the diagnosis results of generator rotor.
