The power industry is the cornerstone of the national economy, converting primary energy into electricity and supplying it to a wide range of users through transmission, transformation and distribution networks. Power safety is not only related to economic security, but also closely linked to daily life and social stability. With the continuous development of the power industry, the safe operation of the power system and the reliability of power supply are increasingly required. Once a fault occurs, it may cause huge losses. Therefore, infrared diagnostic technology is widely used in the power industry, especially thermal imaging equipment, which has become an important tool for daily inspection.

The applications in the power generation link are as follows:

1. thermal power storage coal pile detection: closed coal yard summer internal temperature is high, easy to cause spontaneous combustion, resulting in coal and equipment loss. Thermal imaging equipment can detect temperature anomalies in time and provide early warning to prevent fire.

2. coal transmission area conveyor belt detection: long-term operation of the conveyor belt is prone to overheating due to friction, resulting in aging, fracture, triggering production accidents. Thermal imaging equipment can detect overheating and aging points in all directions to avoid accidental losses.

3. Thermal power turbine equipment detection: turbine generator insulation materials are prone to failure in harsh environments. Thermal imaging equipment can measure the temperature of turbine shaft tile in all directions to ensure safe operation.

4. photovoltaic panel detection: photovoltaic module internal failure will lead to power generation efficiency decline, the formation of “hot spots”. Thermal imaging equipment can discover the fault point in advance, and conduct quick inspection to ensure power generation efficiency.

5. photovoltaic convergence box, inverter detection: photovoltaic power generation scenarios, thermal imaging equipment on the convergence box, inverter visualization temperature measurement, change the traditional inspection methods, improve equipment operation and inspection efficiency.

6. wind turbine body cabin temperature measurement: fan nacelle equipment is easy to cause fire hazards due to high temperature. Thermal imaging equipment to realize remote operation and online inspection, improve the efficiency of operation and inspection, and record the trend of equipment temperature changes.

Thermal imaging equipment also plays an important role in power transmission, substation and distribution:

1. Transmission line insulator detection: timely detection of insulator moisture and stains caused by heating anomalies, to ensure grid safety.

2. wire clip detection: accurate detection of poor contact, corrosion and other problems, to eliminate hidden dangers.

3. Transformer, transformer, lightning arrester and bushing equipment detection: through thermal imaging equipment to detect the heating of these devices to avoid damage due to high temperature.

4. GIS equipment testing: to find the equipment internal metal particles, powder and other hidden problems, improve the level of equipment condition detection.

5. Distribution inspection: thermal imaging equipment to realize the visualization of the electrical joints between the distribution of accurate temperature measurement, rapid detection of hidden problems.
