The invention provides a method and a device for predicting a partial discharge mode of a switch cabinet. The prediction method comprises the following steps: acquiring a plurality of partial discharge signals of the switch cabinet; screening the plurality of partial discharge signals based on a partial discharge signal screening model to obtain predictable partial discharge signals and unpredictable partial discharge signals; predicting the predictable partial discharge signal based on the original partial discharge mode recognition model to obtain a partial discharge mode of the predictable partial discharge signal, and marking a partial discharge mode corresponding to the unpredictable partial discharge signal; based on the plurality of partial discharge signals and the partial discharge mode corresponding to each partial discharge signal, generating a recognition training sample after sample expansion; and based on the identification training sample after sample expansion, retraining the original partial
