The present invention discloses a method and system for diagnosing mechanical faults of high-voltage circuit breakers based on a MIDBO-SVM model. The method first obtains a vibration signal of the circuit breaker, and then uses the obtained vibration signal in combination with a pre-built MIDBO-SVM model to diagnose the mechanical faults of the circuit breaker. During the construction of the MIDBO-SVM model, a good point set strategy and a circle chaos map are used to jointly generate an initial population method to improve the uniform ergodicity of the population. A sine-cosine search strategy and an adaptive weight factor are introduced during the individual position update stage of a rolling ball dung beetle to cause the solution to attenuate and oscillate until it approaches the global optimal solution. A Cauchy-Gauss mutation strategy is used to mutate the individual with the best current fitness in a manner away from the optimal solution, thereby expanding the spatial search range. The method also solves the problems of slow search speed and susceptibility to falling into local optimality in the later stages of traditional algorithms, thereby improving the accuracy of circuit breaker fault classification.
