Review on Mechanical Fault Diagnosis Methods for High-voltage Circuit Breakers
Mechanical failure is still the main fault type of high voltage circuit breaker. Timely and accurate diagno-sis of mechanical fault of high voltage circuit breaker is the key to realize the condition based maintenance of highvoltage circuit breaker and ensure the safe operation of power grid
and related research has been paid extensive at-tention. This paper introduces the basic condition of mechanical failure of high voltage circuit breaker. According tothe basic process of fault diagnosis
this paper summarizes the research status and main problems of the mechanicalfault diagnosis methods for high voltage circuit breaker from three aspects:signal preprocessing
feature extraction
selection and dimension reduction
fault identification method. Finally
the key problems in the field of mechanicalfault diagnosis for high voltage circuit breakers are discussed
and the development of diagnostic methods in the fu-ture is prospected.
