In order to quickly and effectively distinguish the operating state of the circuit breaker and improve the accuracy of the state evaluation, an improved fuzzy comprehensive evaluation model is proposed. The evaluation index is weighted based on the combined weighting method, which avoids the dependence of the traditional analytic hierarchy process on the subjective scoring of the weights. The gray correlation theory is introduced to modify the evaluation results, which effectively overcomes the inherent shortcomings of the principle of maximum membership. The improved fuzzy comprehensive evaluation method is applied to the state evaluation of circuit breakers, and the evaluation indexes are established through time parameters, speed parameters, circuit parameters and electrical characteristic parameters, and then a multi-layer fuzzy comprehensive evaluation model is established. Finally, the evaluation model is used to analyze the laboratory circuit breaker, which verifies the feasibility and effectiveness of the model.
