The high-voltage circuit breaker is the key equipment of the substation

and its vibration may lead to the substation system unstable operation.Because the vibration signal is usually irregular

the dynamic fluctuation is also strong

and has the characteristics of changeability

which makes it difficult to detect.Therefore

it proposes an intelligent detection method of high-voltage circuit breaker vibration signal based on EMD(empirical modal decomposition).It completes the noise reduction and reconstruction of the high-voltage circuit breaker vibration signal.It introduces EDM algorithm to decompose the vibration signal of the high-voltage circuit breaker

extract the vibration signal characteristics

and realize the intelligent detection of the vibration signal.The experimental results show that the vibration signal extracted by the research method is completely consistent with the actual signal fluctuation

and the false alarm rate of intelligent detection is always less than 2.1%

indicating that the application performance of the method is ideal.
