Fault Diagnosis Method of High Voltage Circuit Breakers Based on Wavelet Packet Decomposition and ELM

摘要：

　　In order to improve the method of the existing circuit breaker fault diagnosis, based on the existing shortcomings of mechanical fault diagnosis, a new method for fault diagnosis is proposed based on wavelet packet decomposition and ELM, and feasible diagnostic steps and analysis are also introduced. It uses wavelet packet decomposition extract characteristic vector of combines vibration and acoustic. Then, the characteristic vectors are used to build the input vector of ELM to conduct fault diagnosis. Experiments show that the proposed method is effective to diagnose the mechanical faults of high voltage circuit breakers.
