摘要:

摘要:广东珠海金湾发电有限公司#3发电机大修时,现场试验发现转子绕组有匝间短路迹象。首先通过两极电压平衡试验确定存在匝间短路故障,然后通过绕组交流电压分布试验确定匝间短路故障所处的线圈。转子返厂修理时,根据试验结果拆出故障线圈,分析了短路原因并及时处理了故障绕组,保证了大修工期。

Abstract:

Abstract:While Guangdong Zhuhai Jinwan Power Plant Company Limited No.3 unit overhauling,site test found there is trace of turn to turn short circuit at rotor winding.Turn to turn short circuit was determined by two pole voltage balance test.Winding alternating voltage distribution test determined the coil with failure.After the rotor was sent back to factory to repair, failure was analyzed and repaired.The overhaul duration was secured.
