In today’s era of rapid technological development, drones are playing a significant role in various fields due to their unique advantages. In the power industry, drones have transformed into “inspectors” and have made remarkable contributions to safeguarding power safety.
Drones become “inspectors”
In recent years, with the prosperity of the market economy, the coverage area of high-voltage transmission lines has become increasingly extensive. Due to the fact that power transmission line equipment is placed outdoors for a long time, it is highly susceptible to adverse changes in the climate environment, such as conductor overheating, insulator corrosion, and line aging.
Therefore, power system inspection is a basic guarantee measure for ensuring the healthy operation of the power grid.
For a long time, traditional power inspection mainly relied on manual inspection, requiring workers to climb up the power line poles to inspect equipment such as towers, conductors, and insulators one by one. This traditional inspection method has many drawbacks, such as high labor intensity, low inspection efficiency, insufficient inspection, and difficulty in digitalizing inspection results. It is also affected by terrain and weather conditions, and is prone to attacks by wild animals, lightning strikes, etc. With the implementation of drone power inspection technology, power line inspection will become safe, convenient, and fast. Drone power inspection is a new technology application that uses drones to inspect power facilities to ensure the safe and efficient operation of the facilities. Drone inspection greatly improves inspection efficiency and operational safety. Compared with traditional inspection methods, drone inspection has significant advantages in the power system.
Advantages of drone power inspection
High efficiency and speed
Drones can quickly cover large areas of power line regions in a short time. They are not limited by terrain and can easily fly over mountains, rivers, forests, etc., significantly improving inspection efficiency. For example, large-scale inspection tasks that originally took several days to complete can be completed in just a few hours using drones.
Precise detection
Drones are equipped with advanced high-definition cameras, infrared thermal imagers, etc., and can conduct comprehensive and high-precision inspections of power equipment. The high-definition camera can clearly capture the details of power equipment, making it easier for inspectors to promptly detect potential hazards. The infrared thermal imager can detect the temperature distribution of equipment and identify abnormal situations such as overheating.
Safe and reliable
Drone inspection significantly reduces the safety risks for inspectors. Operators can control the drone remotely or through a ground station from a safe distance, without the need for workers to climb towers or enter dangerous areas.
Cost savings
Although the purchase and maintenance of drone equipment require certain costs, in the long run, drone inspection can save a significant amount of labor and time costs. Because drone inspection can promptly detect equipment failures and avoid greater losses caused by equipment failures, it reduces the operating costs of the power system.
In addition, specific application scenarios for different models also vary. For example, fixed-wing drones are suitable for large-scale or small-scale channel inspections, emergency inspections, and disaster situation surveys, while multi-rotor drones are mainly responsible for detailed inspections.
