| Abstract: | For CPR1000 TA1100-78 half speed generator shaft current monitoring device, this paper puts forward an online validity test method on power platform. The method is simple and practical, the correctness of the detection circuit and the main body of the monitoring device can be fully checked, the reliability of the shaft current detection system can be improved after the generator start. At the same time, combined with the field practice, the abnormal diagnosis process for the shaft current is analyzed, which can provide reference for solving similar problems of the same type of unit. |
