CIRCUIT BREAKER DETECTION METHOD, DEVICE AND SYSTEM

摘要

A circuit breaker detection method, device and system. The method comprises: acquiring a current value and a vibration signal of an electromagnet coil in a circuit breaker in a chronological order (S11); determining, via the current value of the coil, an operation time interval of the circuit breaker (S13); processing the vibration signal within the operation time interval to obtain a fingerprint feature parameter for operation state detection of the circuit breaker (S15); and comparing the fingerprint feature parameter with a preset fingerprint feature database to determine an operation state of the circuit breaker (S17). The present invention addresses the technical problem in which a high detection cost and complex operations are caused by a large volume and complex installation of an existing detection device for a circuit breaker.
