Intelligent circuit breaker is one of the most significant devices in the electric system, and its stability and reliability are quite significant for the operation of the power grid. An online monitoring and fault diagnosis system based on the vibration signal of virtual instrument technology is proposed according to the analysis of online monitoring of vibration signal in intelligent circuit breaker. The system employs the LabVIEW software, for programming HMI and accomplishing the storage, display, analysis and treatment, etc. of the measured data. The sensor and digital signal processing unit forms the field monitoring module and it is installed on the breaker for accomplishing the acquisition and transmission of mechanical parameters, breaking- closing current signal and vibration signal. The experimental results show that the system can reflect the mechanical operating state of intelligent circuit breaker in real time, with friendly man- machine interaction, complete functions and high reliability, etc. Moreover, it implements the expected system of the online monitoring system.
