Circuit breaker abnormity early warning method, system and related device

The invention provides a circuit breaker abnormity early warning method. The circuit breaker abnormity early warning method comprises the steps of obtaining real-time characteristic parameter data including a circuit breaker operation state; performing data processing on the real-time characteristic parameter data to obtain a corresponding time sequence; constructing the time sequence to obtain a time point order sequence; performing mutation analysis on the characteristic parameter data in the time point order sequence to obtain a mutation analysis result; and determining the current operation state of the circuit breaker according to the sudden change analysis result. According to the application, the abrupt change point which may cause the fault can be found in advance before the circuit breaker is abnormal, and the abnormal abrupt change characteristic information can be accurately identified at the early stage of the fault of the circuit breaker through the abrupt change abnormal early warning analysis m
