This paper analyzed the importance of online monitoring device of the breaker in power system, and studied the principle of the mechanical condition monitoring of the breaker, including the method of judging the abnormal action of the current of the open and close coil, the displacement of the moving contact. The papar also analyzed the importance of the data acquisition in the mechanical condition monitoring of the breaker. It studied the realization in eun＇ent data acquisition of the open and close coil, the displacement of the moving cnntact, and proposed the method how to improve the precision, what should be given attention to in application. The test results show that the method has higher accuracy and stability.
