Abstract Aiming at the low efficiency and high risk of traditional live work under strong electromagnetic interference and dense equipment in substations, this study proposes an intelligent unmanned aerial vehicle (UAV) operation system integrating dynamic safety modeling, spraying device, and dual-operator collaborative control technology. An electric-magnetic field joint-constrained dynamic safety distance model S=max(0.00127E, 0.00125B) is constructed, reducing the collision risk by 37.4% compared with the traditional static model (p<0.001. A lightweight carbon fiber folding spraying rod (extension range: 0.3~0.55 m) and dual-mode vector nozzle are designed, achieving a 96.3% obstacle avoidance success rate within a 0.5 m equipment gap. A 5G ultra reliable & low latency communication (URLLC)-based dual-operator collaborative system is developed, compressing the single operation time to within 28 minutes and improving efficiency by 52.2% compared with manual work. Field experiments show that the system realizes full-process closed-loop control of live insulator cleaning and room temperature vulcanizing silicone rubber (RTV) spraying in 220 kV substations, providing a standardized solution for intelligent operation and maintenance of power grids.

Key words： unmanned aerial vehicle (UAV) live insulator operation substation dynamic safety distance model spraying device collaborative control
