Objects above absolute zero will produce thermal radiation, and the surface radiation intensity and matter Body surface emissivity, temperature, etc., in general, radiation is mainly concentrated in the infrared band. Infrared thermal imaging is done by measuring objects The infrared radiation intensity is used to calculate the temperature field on the surface of the object to form a thermal image, and the temperature field of the surface is used to judge the internal heat source and heat of the object. The amount of conduction path, so as to achieve the purpose of monitoring the internal structure of the object, material defects, etc.; according to the atmospheric window, usually the acquisition of the medium wave (wavelength Infrared radiation of 3μm~5μm) or far wave (wavelength 8μm~14μm). When the equipment is in an abnormal state, it usually causes temperature. The abnormality is reflected in the thermal image, and the current operating state and fault condition of the device can be judged by recording and analyzing the thermal image. Figure 1 Schematic diagram of infrared thermal imaging monitoring 4.2 Classification of infrared thermal imaging monitoring Infrared thermography is divided into quantitative thermal imaging and qualitative thermal imaging. Quantitative thermography is evaluated by measuring the approximation of temperature Measure the state of the device or component, compare the temperature approximation with the temperature or baseline data of the in-service device to determine the operating state of the device. Nothing is normal. Qualitative thermography is the thermal profile or thermal profile of the same component or similar component under the same or similar operating conditions. Comparison; in the process of searching for different heat maps and heat profiles, any two or more similar targets do not need to give a specific temperature of heat distribution. The degree value can determine the abnormal state according to the degree of change of the difference. Qualitative thermal imaging can only detect defects, but quantitative thermal imaging can determine the state of evil The severity of the disease. 4.3 Causes of abnormal temperature of mechanical equipment In mechanical equipment, an abnormal increase in temperature is usually caused by insufficient friction caused by insufficient lubrication, misalignment, wear of components, abnormal load, etc. Causes; abnormal temperature drops are usually caused by component failure. For insulation systems, the temperature anomaly is usually caused by insulation materials. Caused by less, aging and improper installation. 4.4 Causes of abnormal temperature of electrical equipment In electrical equipment, abnormally elevated temperatures are usually caused by increased resistance, short circuit, overload, load imbalance, or Causes of improper component installation; abnormal temperature drops are usually caused by component failure. 4.5 Advantages and limitations of infrared thermal imaging monitoring Infrared thermal imaging monitoring has the following advantages. a) Non-intrusive, can be implemented remotely and without contact; b) provide information on the implementation process; c) accurately, quickly and intuitively display the temperature field of the surface of the object; d) can monitor dynamic performance; e) immune to electromagnetic interference, especially for the monitoring of electromechanical systems; f) can be implemented on a completely dull night.
