New breakthrough! State Grid Jingzhou Power Supply Company uses fixed-wing drones for the first time to inspect ultra-high voltage transmission lines

A 1.6-meter-long and 2.4-meter-wide fixed-wing drone of the State Grid Jingzhou Power Supply Company recently successfully completed the inspection of 1,000 kV, 800 kV, and 500 kV ultra-high voltage transmission lines in Songzi and Jianli areas. Inspection missions, this breakthrough marks that the company has once again made new progress in the application of drones

In order to prepare for the inspection, the company carefully surveyed and analyzed the UHV line channel environment in advance, determined the take-off and landing points of each line, and completed route planning. At this critical stage, the staff fully considered various complex factors such as terrain, climate, route direction, etc. to ensure the accuracy and safety of the route

During the trial, the fixed-wing UAV demonstrated excellent performance at high altitudes and in harsh environments. It is equipped with high-definition visible light and lidar devices, which can directly detect equipment defects, quickly solve radar data through software, and generate reports containing information such as line tree distance and intersection crossing. Compared with traditional operation methods, fixed-wing drone inspection time saves more than 80%

According to the news, this inspection included 11 ultra-high voltage transmission lines with a total length of 413.738 kilometers. (Picture/Text: Xie Along)
