In order to improve the efficiency of the transmission line press-connect tubes detection,a UAV charged X-ray detection method is proposed for transmission line press-connect tubes,which is based on the X-ray detection technique principles,combined with applying drones,operating drones to carry detectors and digital imaging panels,to finalising live X-ray inspection.According to the actual work the effect of on-site,this working method not only reduces personal risks,but also improves work efficiency and meets the needs of on-site work.
