Application of infrared thermal imaging in power grid fault detection
Transformer detection
The transformer is a key device in the power system, and its normal operation directly affects the safety of the power grid. Infrared thermal imaging technology can effectively detect the temperature distribution of the transformer and promptly detect overheating problems of the internal coil, core or joint, thereby preventing failures caused by overheating.
Cable line detection
For cable lines, especially underground cables, it is difficult to find fault points quickly and accurately with traditional detection methods. Through infrared thermal imaging, the surface temperature of the cable line can be detected to determine whether there are overheating, aging or damage problems inside the cable.
Switchgear detection
High-voltage switchgear plays a role in protection and control in the power grid. Infrared thermal imaging technology can monitor the temperature changes of the connection points, contacts and other parts of the switchgear, and promptly detect problems such as poor contact and oxidation to prevent equipment failure.
Application of infrared thermal imaging in power grid prevention
Regular inspections
Through regular infrared thermal imaging inspections, we can conduct a comprehensive inspection of power equipment, discover potential problems in a timely manner, avoid equipment running with problems, and improve the reliability of power grid operation.
Fault trend analysis
Infrared thermal imaging technology can record the temperature change trend of power equipment. Through big data analysis, it can predict the deterioration trend of equipment and provide a basis for equipment maintenance and replacement.
Real-time monitoring and early warning
Combined with smart sensors and IoT technology, infrared thermal imaging can realize real-time monitoring and early warning functions for key equipment. When the temperature of the equipment is abnormal, the system will automatically alarm and remind the operation and maintenance personnel to deal with it in time.
Other application
Application in smart grid
In smart grid, infrared thermal imaging technology is combined with big data and cloud computing to achieve full life cycle management of power equipment. Through data analysis and fault prediction, operation and maintenance personnel can formulate maintenance plans in advance and improve the operation efficiency of the power grid.
Drone inspection
Drones are equipped with infrared thermal imaging equipment to inspect high-voltage transmission lines and substations. Especially in complex terrain and high-risk environments, the advantages of drone inspections are more obvious. This not only improves detection efficiency, but also reduces the risks of manual inspections.
