10kV高压相位无线检测系统

The wireless measuring system of phase in 10kV high-voltage

相位检测在供电系统中十分重要。根据三相工频电压的相位,利用微控制器测量降压后的相位差,通过无线收发芯片实现两路10kV高压电网间的相位测量,避免了常规有线测量的可靠性低、安全性差的缺点。给出了测量和控制电路、程序的流程图。所设计的无线相位测量仪,安全性高,使用效果好,测量准确,具有很大的推广应用价值。

It must be checked the voltage phases in the power system when two power systems or transformers work in the parallel system in order to keep the safety of the power grid system. So it is important to check the power phase in high-voltage power supply system .It is realized the lOKv high voltage phase measurement based on difference of three low-voltage phases used MCU（Micro-Control Unit） through wireless receiver/transmitter, and avoided some shortages of the ordinary wire measurement. It is given the measurement and control circuits, software diagram of the measurement system in the paper. The wireless phase measuring instrumentation has better value of implement as its high in safety, good effect on application, accurate in measurement.
