Development of Multifunctional Circuit Breaker Reliability Testing Device Based on DSP
In order to reduce the personnel cost of circuit breaker testing and strengthen the monitoring of circuit breaker tripping and closing circuits,it is extremely necessary to deepen the research on the testing device. Therefore,a multifunctional circuit breaker reliability testing device based on DSP is proposed. Based on the objective demand for comprehensive analysis of multi-source data during the reliability testing stage of circuit breakers,the F28335 DSP chip,a digital signal processing chip,is adopted as the core of the device. It is used to integrate and process the digital signals during the testing stage. Based on the power selection module,circuit breaker mode selection module,function selection module,LCD display module,three-phase inconsistency testing module,anti-jump testing module,and tripping and closing resistance measurement module,the overall structure of the multifunctional circuit breaker reliability testing device is completed. Through experiments,it has been proven that the designed multifunctional circuit breaker reliability testing device can automatically perform three-phase inconsistency and anti jump tests on different types of circuit breakers,while monitoring the resistance of the circuit breaker's tripping and closing circuit,greatly improving the work efficiency of maintenance personnel.
