Research on Discharge Influencing Factors During X-Ray Detection UAV Entering Transmission Lines
X-ray detection is an effective way to identify defects in tension clamps of transmission lines.Using UAVs carrying X-ray detection equipment can achieve live detection,which is more convenient than power outage detection.However,current research has not systematically analyzed the influencing factors of discharge during UAV live detection.Therefore,finite element technology simulation was used to explore the effects of the horizontal position of the UAV entering the phase to phase electric field during X-ray live detection,the vertical spacing between wires,the length of the insulation rope of the UAV mounted detection equipment,and the longitudinal absolute distance between UAV and wires on UAV discharge.Research has found that during the dynamic process of entering the interphase electric field,the electric field distortion is most severe when the UAV is located directly below the wire.The vertical spacing between transmission lines is nonlinearly related to the degree of electric field distortion.The shorter the spacing,the greater the steepness of electric field distortion.The vertical spacing between 110 kV and 220 kV transmission lines should be kept above 1.4 m and 1.7 m,respectively.Under the premise of unchanged UAV position,shortening the length of the insulation rope has little effect on the UAV electric field.At voltage levels of 110 kV and 220 kV,the absolute distance between UAV and the conductor should be controlled above 38 cm and 53 cm,respectively.
