A detection and processing system for external vibration signals during operation of high voltage circuit breakers is introduced. System consists of computer, mechanical vibration signal acceleration sensor and system processing software and other components, with data acquisition, signal processing and other functions. Through the signal processing technology, the response characteristics of the vibration signal in time domain and frequency domain are analyzed, and the corresponding relationship between the external vibration signal and the movement and impact of the internal mechanical components is revealed. Taking the closing damper of the sample circuit breaker as an example, the mechanical condition of the closing damper is quantitatively described by the detection and processing of the vibration signal. The monitoring system acquires the vibration signal from the sensor mounted on the surface of the circuit breaker without electrical wiring. This method of detection is suitable for on-line monitoring of high voltage circuit breakers.
