Autonomous drone inspection adds 'new color' to the operation and maintenance of high-altitude transmission lines

Recently, the drone team members of the Qinghai Power Transmission and Transformation Transportation Inspection Branch carried out autonomous drone inspections of the 110 kV Guowen I line near Qingzhen Mountain at an altitude of 4,300 meters in the Goluo area.

After all preparations on site were in place, drone operator Bao Yuhai reported to the person in charge of the work, Zhu Yimin: "The drone system is all normal, the weather on site is good, the autonomous inspection route has been uploaded, and application for takeoff has been made." Zhu Yimin replied: "It's ready to take off." A drone slowly took off and flew to the inspection tower according to the planned route, realizing the transition from manual operation to autonomous inspection. This was also the first time that 110 kV was carried out in a high-altitude area. Autonomous drone inspection of power transmission lines.

In recent years, the company has actively explored the large-scale and intelligent application of drones in daily operation and maintenance work. The successful implementation of autonomous drone inspections also marks the company's transformation of operation and maintenance work into intelligence. A solid step towards upgrading.

It is understood that compared with manual drone inspections, drone autonomous patrols can be carried out by drones after preliminary preparation work such as three-dimensional modeling and route planning of transmission lines. The operator starts the flight mission with one click, eliminating the need for manual operation by the operator throughout the process, freeing the operator's hands and greatly reducing the probability of flight hazards caused by human misoperation; during the autonomous inspection process, the drone will follow the planned route and instructions Taking multi-angle, close-range photos of line poles and towers, the drone operator only concentrates on viewing the pictures returned by the drone in real time, and conducts timely analysis and judgment, which solves the problem of low refinement and greatly improves the efficiency of line inspections. and quality of work.

So far, the drone team has completed the inspection of 45.8 kilometers of transmission lines and independent inspections of 153 base towers in the Goluo area, realizing the intelligent transformation from traditional human inspection to manual inspection to autonomous inspection. The transformation has greatly improved the level of intelligent operation, maintenance and safe operation of transmission lines.
