Fault diagnosis system of hydroelectric generator

The invention relates to the technical field of fault diagnosis, in particular to a fault diagnosis system of a hydroelectric generator. The defects that in the prior art, the detection work of the hydroelectric generator is extremely time-consuming and labor-consuming, faults cannot be found punctually and accurately, and the safety is low are overcome. The fault diagnosis system comprises a detection module, the detection module specifically comprises a voltage detection unit, a noise detection unit, a temperature detection unit and a vibration detection unit, a processing module is arranged at the output end of the detection module, and the processing module specifically comprises a receiving unit, a storage unit, a comparison unit and an action unit. Various data of the generator are monitored in real time through the voltage detection unit, the noise detection unit, the temperature detection unit and the vibration detection unit, the data are transmitted to the processing module to be processed in real time and are compared with normal values, when an abnormal state occurs, the action unit can achieve warning in time, and the working safety coefficient of the hydroelectric generator is improved.
