In the 220-kilovolt substation in Guangzhou, China's first "Zhiyun"-branded high-voltage live-line operation robot for substations successfully completed its full-process practical deployment, achieving autonomous inspection and equipment manipulation in high-voltage environments. This milestone represents a significant advancement in implementing the "machine replacing human" strategy for high-risk operations within the power system.
In conventional substations, high-voltage live-line operations require personnel to manually wear cumbersome insulating protective gear, resulting in not only low operational efficiency but also substantial safety risks, including electric shock and arc flash injuries. To address these challenges, the "Zhiyun" robot is equipped with an omnidirectional mobile chassis and a dual-arm collaborative design, with a combined maximum load capacity of up to 5 kg. Integrated with a laser positioning system, the robot achieves millimeter-level operational precision and can independently execute a complete sequence of tasks, including switching operations and line inspections in 10-kilovolt switchgear compartments. Notably, the robot introduces a pioneering data interaction protocol between the power grid system and robotic control systems. Through a remote operation platform, maintenance staff can initiate "one-click" commands, improving operational efficiency by 70% compared to manual methods. Furthermore, the robot operates continuously without fatigue, significantly reducing labor demands and associated costs.
According to the Technical Director of China Southern Power Grid, the "Zhiyun" robot has undergone multiple rounds of rigorous testing under extreme environmental conditions. It is planned for deployment across more than 20 substations in the Pearl River Delta region, offering safe, reliable, and efficient operation and maintenance solutions in support of the new power system construction.
