    摘要:

    维修高压线路故障时,通过测量周围电场对故障原因做出快速判断至关重要。基于逆压电效应原理设计的压电-压阻耦合式电场传感器可以完成复杂环境下的非接触测量,且具备安全性高、灵敏度和线性度好的优点。通过有限元仿真和实测实验,实现了该电场传感器与所测电场强度取向夹角为 0°~75°时的场强测量。实验结果表明,当取向夹角在 45°内时,实测结果与仿真结果差距在 1 mV 内。在实验基础上,经理论分析和仿真论证了利用无人机携带该电场传感器扫过输电线路来监测故障原因并定位故障位置的应用可行性。

    Abstract:

    The repair of high-voltage line faults necessitates the rapid determination of the cause of the fault by measuring the surrounding electric field. The piezoelectric-piezoresistive coupling electric field sensor, designed based on the principle of inverse piezoelectric effect, can complete the non-contact measurement in a complex environment, owing to the advantages of high safety, high sensitivity, and good linearity. This study performs field strength measurement using the finite element simulation and experimental measurement when the orientation angle between the electric field sensor and the measured electric field intensity is within the range 0° -75° . The experimental results showed that when the orientation angle was less than 45, the difference between the measured and simulation results was less than 1 mV. Based on this experiment, theoretical analysis and verification were conducted to determine the feasibility of detecting the cause and location of the fault by using a UAV carrying the electric field sensor to scan the transmission line.
