Abstract

For rapid fault diagnosis of operating mechanism of high-voltage circuit breaker

a fault diagnosis method based on fuzzy RBF neural network was presented. In this method

the feature parameters t

and I

were extracted by analyzing the opening/closing coil current of high-voltage circuit breaker. Then

a fuzzification layer was added in the RBF neural network to fuzzify the characteristic parameters. Finally

these fuzzified

characteristic parameters were input to the RBF neural network for fault identification and classification. Eighty-eight groups of experimental data of ABB VD4 circuit breaker were taken as the training samples to establish a fault diagnosis model of the circuit breaker’s operating mechanism based on fuzzy RBF neural network for 4 kinds of fault types

and 12 groups of test samples were used to verify the validation of the proposed model. The results show that the model is valid and the accuracy of fault diagnosis reaches 99%. Compared with the fault diagnosis method based on fuzzy BP neural network

the proposed fault diagnosis method based on fuzzy RBF neural network has faster convergence speed

shorter training time

and smaller mean square deviation（0.107 3）.
