Recently, Wuhan’s power supply authorities have innovatively deployed drone technology to carry out de-icing operations on transmission lines during winter cold waves, significantly enhancing the efficiency and safety of power grid maintenance. Traditional manual de-icing methods are not only time-consuming and labor-intensive but also pose significant risks due to high-altitude work, especially under icy conditions caused by freezing rain and snow. To address this, State Grid Wuhan Power Supply Company has introduced specialized drones equipped with de-icing devices. Operated remotely, these drones can precisely remove ice from high-voltage power lines. Featuring high-definition cameras and infrared thermal imaging systems, they enable real-time monitoring of line conditions and utilize high-frequency vibration or thermal energy to melt ice layers—boosting operational efficiency several times over manual methods. This initiative not only ensures stable urban power supply but also marks a significant step toward automation and intelligence in smart grid operations. Going forward, Wuhan’s power authorities plan to further expand an integrated drone-based model combining inspection and de-icing, providing stronger technical support for grid resilience during extreme weather events.
近日，武汉供电部门在冬季寒潮期间创新采用无人机技术开展输电线路除冰作业，有效提升了电网运维效率与安全性。面对低温雨雪天气导致的线路覆冰问题，传统人工除冰方式不仅耗时费力，还存在高空作业风险。为此，国网武汉供电公司引入搭载除冰装置的特种无人机，通过远程操控精准清除高压线路上的冰层。该无人机配备高清摄像头和红外热成像系统，可实时监测线路状态，并利用高频振动或热能装置融化冰层，作业效率较人工提升数倍。此次应用不仅保障了城市电力供应的稳定，也标志着智能电网运维向自动化、智能化迈出重要一步。未来，武汉供电部门计划进一步推广无人机巡检与除冰一体化作业模式，为极端天气下的电网安全提供更强技术支撑。
