Abstract
The automatic fault diagnosis method of high-voltage vacuum circuit breaker has poor fault diagnosis effect.Therefore,the automatic fault diagnosis of high-voltage vacuum circuit breaker based on abnormal current signal is proposed.The characteristic parameters of the travel curve of the permanent magnet mechanism of the high-voltage vacuum circuit breaker are extracted,and the fault diagnosis model of the high-voltage vacuum circuit breaker is constructed based on the abnormal current signal.The automatic fault diagnosis process of the high-voltage vacuum circuit breaker is designed to realize the diagnosis.The results show that this method performs well in fault identification.
