Construction method and application of GIL mechanical fault diagnosis model, computer readable medium and fault diagnosis system

The invention relates to a construction method and application of a GIL mechanical fault diagnosis model, a computer readable medium and a fault diagnosis system, and the method comprises the steps: obtaining GIL vibration-induced variable electric signals at the early stage of a GIL first mechanical fault, the GIL vibration-induced variable electric signals are divided into a plurality of groups, and the GIL vibration-induced variable electric signals are respectively from a plurality of GIL with the GIL first mechanical fault; carrying out noise reduction processing on the GIL vibration-induced variable electric signals, and constructing training set samples by using the processed signals; constructing a deep residual shrinkage network initial model, and training the deep residual shrinkage network initial model by using the training set sample to obtain a GIL mechanical fault diagnosis model for diagnosing a first type of GIL mechanical fault; wherein the GIL first type mechanical fault is a GIL metal shel
