Mechanical characteristic condition monitoring system of high voltage circuit breaker

Abstract

Aiming at the current research status and shortcomings of the mechanical characteristic condition monitoring system of high voltage circuit breaker, a condition monitoring system of high voltage circuit breaker based on DSP is developed in order to find the operation state of circuit breaker in time and improve the reliability. The system uses TMS320C28346 as the control core and AD7606 as the sampling chip, which can realize the collection, conversion, transmission and display of monitoring data, and can monitor the closing and opening coil current and contact stroke of the circuit breaker in real time. Through experimental tests, the results show that the system meets the design requirements of each parameter error below 2%.
