摘要
设计了一套基于16位单片机的智能型负荷监测终端控制器,可对变压器台区的三相不平衡电流、开关状态及地网漏电信号进行实时检测监控,并借助台区的配变监测计量终端上传到供电监控系统,给出了部分硬件电路和软件编程。试验结果证明该设计方案性能稳定,可为低压线路漏电监测提供可靠依据,能够有效地保障变压器台区用电安全。
This paper designs a set of intelligent load monitoring terminal controller based on 16-bit single-chip computer. It can detect and monitor three-phase unbalanced current, switching state and leakage current signal in transformer station area in real time. With the help of the distribution transformer monitoring and measuring terminal in the station area, it is uploaded to the power supply monitoring system. Some hardware circuits and software programming are given. The test results show that the design scheme has stable performance. It can provide reliable basis for leakage monitoring of low-voltage lines, and can effectively guarantee the safety of power consumption in transformer stations.
