The operation frequency of generator outlet circuit breaker (GOCB) in pumped storage power stations are approximately a thousand times higher than that in conventional hydropower stations. As we know, the mechanical failure accounts for a high proportion of all the faults. Therefore, it is of great practical significance to diagnose the mechanical characteristics of GOCB. However, due to high operation frequency, the vibration signal is much more complex and nonlinear, which makes it difficult to diagnose the mechanical fault. This paper proposes a mechanical fault diagnosis method of GOCB based on deep residual shrinkage network. Firstly, the original vibration signal is segmented in time domain. Each part after segmentation is integrated to reflect the characteristics of vibration signal amplitude, phase and frequency change. Four typical fault types are simulated in the laboratory, and the vibration characteristic database under normal and four fault conditions is established. Then in the training model, a sub-network is applied to automatically set the threshold in the soft threshold, which can enhance the efficiency of feature training and improve the accuracy of fault diagnosis. Finally, the fault diagnosis method is verified by test data. The results show that The diagnostic accuracy of this method reaches 97%. Experiments on a 24 kV GOCB verify the effectiveness of the proposed method.
