摘    要:本文提出一种高压电力线路相位无线检测的新方法,该方法由2个发送装置和1个接收装置组成,发送装置主要利用电磁耦合和限幅电路采集电网电压信号,将采集到的电网电压信号进行ASK调制发送到接收装置,接收装置将接收到的来自2个发送装置的电压信号进行解调,解调后恢复原来相位信号进行实时比较得到相位脉冲信号,从而间接地实现了对被测线路不同相之间的相位进行检测,发送模块采用高频发送来解决强磁场干扰问题,利用该技术已成功地开发了高压电力线路无线核相仪,该装置可以方便地对电网并网合闸进行检测。

关 键 词:高压  电力线路  相位  无线检测

Abstract:A new method of wireless phase measurement for high voltage electric power line is introduced. The method includes transmitting and receiving devices.The voltage signal of the power line is acquired u- sing the electromagnetic coupling and clipping circuits in the transmitting device.Then,the acquired voltage signals are ASK modulated and sent to the receiving device.The receiving device demodulates the received signals,and the demodulated signals restore their original phase information that is compared to get the phase pulse signal.Therefore the phase measurement of the power line under test is indirectly achieved. Based on this technique,wireless phase detector for high voltage power transmission line was successfully designed and applied.
Keywords:high voltage  electric power line  phase  wireless measurement
