The power supply department in Nantong utilized fixed drone nests to complete a 19-day critical operation and maintenance task for the 500-kilovolt Taisheng and Taili transmission lines on April 25. The drone nests can automatically deploy drones to perform inspections by pre-setting patrol routes for power protection lines. Each channel inspection takes 15 minutes per round, while infrared temperature measurement for each tower is conducted every 20 minutes, with data transmitted in real time to the smart power protection command platform. The modular drone nest network consists of compact units, each smaller than one cubic meter, designed for flexible deployment near substations, critical transmission corridors, and high-risk construction zones. These nests can complete self-checks and launch drones within 45 seconds, autonomously handling takeoff, landing, battery charging, and data transmission. With a maximum flight time of 50 minutes and an effective operational radius of five kilometers, the system ensures the safe and stable operation of main transmission channels. Nantong's 500-kilovolt transmission network has exceeded 800 kilometers in total length in 2025. To date, 17 fixed drone nests have been established across the city, with plans to deploy over 50 additional nests. This expansion aims to achieve refined, comprehensive inspections of 500-kilovolt transmission line infrastructure and corridors, along with 24-hour rapid response capabilities. 4月27日,中国日报刊发英文报道《Nantong pioneers innovative drone for power grid inspection》。报道指出,国网南通供电公司全面推进无人机巢建设。目前,该市已建成17个无人机固定机巢,覆盖4所500千伏、10所220千伏变电站周边输电通道。未来当地还将建设超50座无人机巢,实现精细化巡检、确保24小时快速响应。
