摘要
设计了一个塑壳断路器四段保护功能检测系统并对其进行了分析。该系统以数字信号处理器(DSP)TMS320F28035为核心,配合相应的外围电路对塑壳断路器四段保护功能进行了测试,并给出了该测试系统的总体结构框图及各接口电路。采用RS-485串行总线与上位机进行通信,并可在上位机设置相应的测试参数和显示测试结果。
A testing system of molded case circuit-breaker four level protect function was designed and analyzed. The system made the digital signal processor(DSP) TMS320F28035 as the core, with the corresponding circuits and testing molded case circuit-breaker four level protect function. Overall structure diagram and the interface circuit of the protect function testing system were expounded. This system adopted RS-485 serial bus to communicate with the PC. The PC set the parameters and displayed the result.
