Meaning
- Substation inspection drone is an industrial grade drone specifically designed for automated inspection of outdoor equipment and station environment in substations.
- Equipped with visible light, infrared thermal imaging, zoom cameras and other devices, it is an important equipment for the safe operation and maintenance of intelligent substations to conduct non-contact inspections of high-voltage equipment such as transformers, circuit breakers, insulators, and knife switches, and timely detect hidden dangers such as heating, damage, foreign objects, and oil leakage.
Basic principles
Principles of Flight and Positioning
Using a multi rotor drone as a platform, it automatically cruises along a preset route within the substation, combined with high-precision positioning to achieve fixed-point hovering and close range observation, avoiding equipment and structures.
Principle of Infrared Temperature Measurement
By using an infrared thermal imaging device to collect the surface temperature distribution of the equipment, potential hazards such as joint overheating, local temperature rise, and abnormal heating can be identified.
Principle of visible light detection
Use a high-definition zoom camera to capture the appearance of the equipment and inspect visual defects such as insulator damage, loose fittings, foreign object suspension, rust, oil leakage, etc.
Principles of Data Transmission and Analysis
Real time feedback of images and temperature data to the backend system, automatic marking of hidden danger locations, and generation of standardized inspection reports.
Main features
- Specially designed for complex electromagnetic and equipment intensive environments in substations, with strong anti-interference ability
- Automatically plan flight routes, achieve fully autonomous inspections, without the need for frequent manual operations
- Equipped with dual detection capabilities of visible light and infrared thermal imaging, capable of day and night inspections
- Non contact, remote observation to avoid personnel entering high-pressure hazardous areas
- Stable hovering and precise positioning, capable of fine observation of key equipment
- High inspection efficiency, traceable data, convenient for comparative analysis and closed-loop management
Application scope
