摘要
随着无人机巡线的发展,无人机距离架空导线过近会发生感应放电,进而影响无人机数据传输系统的稳定性,因此研究无人机与架空导线之间的放电距离尤为重要。本文首先建立电容模型来阐述二者感应放电的机理,然后选取不同悬浮导体模型和两种型号无人机,分别进行与架空导线之间的电场仿真,分析形状因素对各模型和导线之间场强的影响,结合气体放电理论,得到无人机各形状因素对无人机与导线之间放电距离的影响程度。最后实验测量不同悬浮导体和无人机与导线的感应放电距离,验证了仿真,并得到典型无人机与110k V线路导线的感应放电距离参考值。
The induced discharges occur when the unmanned aerial vehicles( UAVs) are near the overhead lines,which will affect the stability of data transmission system of UAVs. With the development of inspection on line by using UAVs,it is particularly important to study the discharge distance between UAV and overhead lines. In this paper,the capacitive model was established to explain the mechanism of induced discharges. Then,different suspension conductor models and two types of UAVs are selected to simulate the electric field with the overhead conductor respectively,so that we could study the influence of the shape factor on the electric field. Combined with the theory of gas discharge,the impact of the induced discharge distance between UAVs and conductor is obtained. Finally,the experiment of measuring the induced discharge distance of different suspended conductors and UAVs with overhead lines is carried out,which verifies the simulation and obtains the induced discharge distance of typical UAVs and 110 k V overhead lines.
