Detection method, apparatus and system for breaker

The present invention discloses a detection method, a detection apparatus and a detection system for a breaker. The detection method comprises the steps of: acquiring current values of an electromagnet coil in the breaker and vibration signals in chronological order; determining a working time interval of the breaker through the current values of the electromagnet coil; processing the vibration signals within the working time interval to obtain a fingerprint characteristic parameter used for detecting a working state of the breaker; and comparing the fingerprint characteristic parameter with a preset fingerprint characteristic database to determine the working state of the breaker. The detection method of the present invention solves the technical problems of high detection cost and tedious operation caused by large volume and tedious installation of equipment for detecting the breaker.
