A method for predicting the residual mechanical life of a low-voltage circuit breaker of an electric power system comprises the steps that parameters of the low-voltage circuit breaker are obtained, and the parameters comprise current, voltage and temperature; extracting original characteristics of the parameters, constructing a behavior sequence of the low-voltage circuit breaker, and processing the behavior sequence by adopting a random walk strategy to obtain behavior representation; the original features are input into a LateAttention LSTM module, the behavior representation is input into a DeepFM module, and time sequence representation and derivative behavior representation are obtained; inputting the time sequence representation and the derivative behavior representation into TACROssBlock, and interactively outputting joint features of the time sequence and the behavior; inputting the combined characteristic of the time sequence and the behavior into a downstream structure to obtain the residual mechan
