Overview of Non-Contact Infrared Thermometers
The so-called infrared temperature measurement technology is a technology that uses an infrared thermometer to measure the actual temperature of the measured object. Its core lies in the infrared thermometer. With the development of China's science and technology, our country has also mastered the infrared temperature measurement technology, and independently developed its own infrared thermometer, which has the advantages of accurate measurement, non-contact, safety and reliability, wide temperature measurement range, long life, and extremely fast response. It has been widely used in power industry.
The temperature measurement principle of the infrared thermometer is to convert the infrared radiant energy emitted by the object into an electrical signal. The size of the infrared radiant energy corresponds to the temperature of the object itself. According to the size of the converted electrical signal, the temperature of the object can be determined. The infrared thermometer has many advantages, not only has a long service life, but also the operating system is very safe and stable. We need to use infrared thermometers to ensure that my country's distribution network can work normally.
Non-contact infrared thermometers can determine the surface temperature by measuring the infrared energy radiated by the target surface. During the peak summer season, the equipment is prone to abnormalities due to the high load and high-temperature operating environment. Although the sparks of the equipment can be seen during the night patrol with the lights off, the abnormal parts of the equipment cannot be accurately located due to factors such as weak light and narrow field of vision. If some equipment has heating defects, the traditional auxiliary measures can not be judged accurately and not in time. When the substation is turned off at night, the infrared thermometer is used to face the equipment, and the outline of the equipment is clearly visible, and the maximum temperature, minimum temperature, average temperature and other parameters of the target equipment can be intuitively displayed with numbers and images, and abnormal equipment and equipment can be identified in time The heat-generating defective parts effectively block the way for accumulative hidden dangers of equipment to be converted into defects.
Shanyu infrared temperature measurement technology has the advantages of non-contact measurement, fast response, high sensitivity, and large measurement range. When the equipment is running with electricity, it can find thermal defects that cannot be found by other monitoring methods, and reduce unplanned downtime caused by faults. It has the advantages of advanced diagnosis, etc., and has been widely used in the electric power industry.
With the advancement of science and technology, infrared temperature measurement technology is becoming more and more popular, and the operation is becoming more and more intelligent. It is necessary to master the principle, influencing factors, diagnostic methods and application of infrared temperature measurement technology in substations. It can detect the defects of equipment in time, which brings great convenience to the operation and maintenance personnel, and prevents unnecessary accidents caused by equipment defects that cannot be found in time. Since the nighttime patrol is carried out in contact with the temperature, it needs to be carried out on the tower at night, so there is a great potential safety hazard. With an infrared thermometer, you only need to aim, press the trigger, and read the temperature data on the LCD display. Infrared thermometers are lightweight, compact, easy to use, and can reliably measure hot, dangerous, or hard-to-reach objects without contaminating or damaging the object being measured. Infrared thermometers can measure several readings per second, while contact thermometers take several minutes to measure per second, which not only reduces work intensity, improves work efficiency, but also greatly improves work safety.
