一种实用的新型高压无线核相装置的设计

A Practical Design of a New High Voltage Wireless Check Phase Device

文章提出了一种对高压线路不同相进行无线检测的方式。应用无线电理论,在天线电感线圈上对电动势产生感应的检测原理,同时采用串联电路与窗口比较器来实现对电路相位的采集。对含有相位信息的信号进行调制后,发送装置将调制后的信号无线发送给接受装置,接受装置对其解调之后,与电路进行测量与比较,在两条被测线路之间存在一定的相位差,即实现对高压线路的相位检测。

This paper presented a wireless detection method for different phases of high voltage lines. Based on the radio theory, the detection principle of induction on the inductor coil was introduced. At the same time, a series circuit and window comparator were used to achieve the acquisition of the phase of the circuit. After modulation of the signal containing phase information, the transmitting device sended the modulated signal to the receiving device. After the demodulation of the receiving device, the circuit was measured and compared, and there was a certain phase difference between the two tested lines, that was, the phase detection of the high-voltage line was realized.
