非接触式高频行波传感器参数的研究

The Parameters Research of Non-Contact High Frequency Wave Sensor

该文提出了一种用于行波测距的非接触式高频行波传感器,绘制传感器的等效电路并进行仿真和实验研究,结果表明,金属板采集到的信号电压幅值随导线与金属板之间的距离成正比变化,导线与金属板之间介质的相对介电常数成反比变化。

This paper presents a non- contact of high- frequency traveling wave sensor for traveling wave fault location in transmission line,draws an equivalent circuit diagram of the sensor and simulation and experimental study.The result shows that the metal plate collected signal of voltage amplitude changes proportional with the distance between wire and metal plate,varies inversely with the relative dielectric constant between the wire and the metal plate medium.
