Rapid Recognition System of Circuit Breaker Status Based on Wavelet Packet Decomposition and SVM

摘要

For circuit breaker failure state is difficult to identify quickly, this paper put forward a rapid recognition method of circuit breaker status based on wavelet packet decomposition and Support Vector Machine (SVM). After db3 wavelet packet decomposition, the extracted circuit breaker vibration signal has a two-stage classification in SVM and the circuit breaker status will be quickly identified. The experimental results show that rapid recognition system of circuit breaker status based on wavelet packet decomposition and SVM can improve the speed of the circuit breaker fault diagnosis effectively without reducing the diagnosis accuracy.
