“The pole and tower connection fittings and drainage plate are stable and normal. If they fly lower, we should pay special attention to this insulator.” Recently, the UAV pilot of the transmission operation inspection center of State Grid Yulin power supply company carried out UAV inspection on the 110 kV Dangjin line, and analyzed and recorded the panoramic view of the tower and channel from the camera, so as to prepare for the peak summer.

With the rising temperature, in order to ensure the stable, safe and reliable operation of the power grid during the peak summer, State Grid Yulin power supply company has formulated a special scheme for UAV patrol inspection, which effectively combines UAV patrol inspection and manual State Patrol inspection into the daily operation and maintenance of the line, so as to achieve the purpose of aboveground and underground, multi angle and close-up patrol inspection, improve the operation and maintenance level and patrol inspection efficiency of the transmission line, and realize the “no dead corner” of transmission line patrol inspection. This patrol inspection focuses on the detailed patrol inspection of UAV on the lines crossing the expressway section and single power supply lines, and the inspection and screening of the foundation, tower body, support, conductor, insulator string, connecting hardware, shockproof hammer, tension clamp, overhead ground wire and other equipment of the transmission line through UAV capture and photography, so as to check whether the tension wire and suspension clamp are loose, whether the conductor is broken, whether the insulator is cracked, whether the ground wire is rusted and so on, Understand the operation status of line equipment in detail.

So far, the company’s UAVs have flown 960 kilometers, photographed 697 towers, found and handled 35 hidden defects, and effectively improved the health level of transmission lines.
