| Abstract: |
| To solve problems of a large variety of test items, complicated operation and low efficiency of test, a test and analysis system for action characteristics of AFDD(Arc Fault Detection Device) is researched. A comprehensive test circuit is designed by using electromagnetic switches, and its automation control and monitoring are realized with the switch states taken as controlling and observed quantities. The electromechanical coupling feedback control strategy based on voltage and mechanical displacement is used to improve the operation performance of arc fault simulator, and the success rate of arc fault simulation is improved. Simultaneously, the running state of the hardware equipment of the lower computer is controlled and monitored by the upper platform, and the arc voltage and current are collected in real time. The system can not only complete the automation test for action characteristics of AFDD, but also have functions of waveform acquisition and storage, test report automatic generation and so on, which greatly improves the test automation level and efficiency, reduces the interference of human factors and lays a foundation for further research on the formation mechanism of arc fault and arc fault detection technology. |
