How is it detected using an infrared thermometer?
Infrared thermometer detection is an online monitoring (non power outage) high-tech detection technology that combines optoelectronic imaging technology, computer technology, and image processing technology. By receiving infrared radiation emitted by an object, the thermal image is displayed on a fluorescent screen to accurately determine the temperature distribution on the surface of the object. It has the advantages of accuracy, real-time, and speed. Any object, due to the movement of its own molecules, continuously radiates infrared thermal energy outward, forming a certain temperature field on the surface of the object, commonly known as a "thermal image". Infrared diagnostic technology measures the surface temperature and temperature field distribution of equipment by absorbing this infrared radiation energy, thereby determining the heating status of the equipment.
At present, there are many testing equipment that use infrared diagnostic technology, such as infrared thermometers, infrared thermal televisions, infrared thermal imagers, and so on. Devices such as infrared thermal televisions and infrared thermal imagers use thermal imaging technology to convert invisible "thermal images" into visible light images, making the testing effect intuitive and highly sensitive. They can detect subtle changes in the thermal state of the equipment, accurately reflect the internal and external heating conditions of the equipment, and have high reliability, which is very effective in detecting equipment hazards.
The infrared thermometer diagnostic technology makes reliable predictions of early fault defects and insulation performance of electrical equipment, improving the preventive testing and maintenance of traditional electrical equipment to predictive maintenance, which is also the direction of modern power enterprise development. Especially with the development of large units and ultra-high voltage, the reliable operation of the power system is related to the stability of the power grid, and increasingly high requirements are put forward. With the continuous development and maturity of modern science and technology, the use of infrared state monitoring and diagnosis technology has the characteristics of long-distance, non-contact, non sampling, non disassembly, and accurate, fast, and intuitive. It can monitor and diagnose most faults of electrical equipment in real-time online (almost covering the detection of various faults of all electrical equipment). It has been highly valued by the domestic and international power industry (an advanced condition based maintenance system widely used in the late 1970s abroad) and has developed rapidly. The application of infrared detection technology is of great significance in improving the reliability and effectiveness of electrical equipment, improving operational economic benefits, and reducing maintenance costs. It is currently a widely promoted and effective method in the field of predictive maintenance.
With the continuous development of technology, the optimal design and new advancements of infrared thermometers provide users with various functions and multi-purpose instruments, expanding their choices. Other options include ease of use, maintenance and calibration performance, and price. When selecting a thermometer model, the measurement requirements should first be determined, such as the temperature of the target being measured, the size of the target being measured, the measurement distance, the material of the target being measured, the environment in which the target is located, response speed, measurement accuracy, whether to use a portable or online type, etc; Select the instrument model that can meet the above requirements from the comparison of various existing models of temperature detectors; Choose the best combination in terms of performance, functionality, and price among many models that can meet the above requirements.
