Breaker energy storage spring fault severity assessment method and system and medium

The invention discloses a fault severity assessment method and system for an energy storage spring of a circuit breaker and a medium. The fault severity assessment method for the energy storage spring of the circuit breaker comprises the steps of collecting an elastic force signal of the energy storage spring of the circuit breaker within a specified duration; extracting a time domain feature vector from the elastic force signal of the energy storage spring of the circuit breaker; and inputting the time domain feature vector into a pre-trained energy storage spring fault severity evaluation model to obtain a fault severity evaluation result of the circuit breaker energy storage spring. According to the fault severity assessment method for the circuit breaker energy storage spring, the time domain feature vectors adopted by the method can accurately reflect dynamic change information of different fault degrees of the circuit breaker energy storage spring, and the method has the advantages of being simple, effi
