What is the difference between an infrared thermometer and a temperature gun?
Infrared thermometer technology in the production process, in product quality control and monitoring, equipment online troubleshooting and safety protection as well as energy saving plays an important role. In the past 20 years, non-contact infrared thermometer in the rapid development of technology, performance continues to improve, functionality continues to enhance the variety continues to increase, the scope of application also continues to expand, the market share grows year by year. Compared with the contact temperature measurement method, infrared temperature measurement has a fast response time, non-contact, safe to use and long service life and other advantages. Non-contact infrared thermometer including portable, online and scanning three series, and a variety of options and computer software, each series has a variety of models and specifications. In different specifications of the various models of thermometer, the correct choice of infrared thermometer model is very important to the user.
Infrared diagnostic technology on the early failure of electrical equipment defects and insulation performance to make reliable predictions, so that the traditional preventive testing of electrical equipment maintenance (preventive testing is the introduction of the Soviet Union's standards in the 1950s) to predict the state of maintenance, which is the direction of the development of the modern electric power enterprises. Especially now the development of large units, ultra-high voltage, the reliable operation of the power system, related to the stability of the power grid, put forward more and more high requirements. With the continuous development of modern science and technology maturity and increasing improvement, the use of infrared condition monitoring and diagnostic technology has a long distance, no contact, no sampling, no disintegration, but also accurate, fast, intuitive and other characteristics, real-time online monitoring and diagnosis of most of the faults of the electrical equipment (almost all electrical equipment can be covered by a variety of faults detection). It is highly valued by the power industry at home and abroad (an advanced state maintenance system commonly used in foreign countries in the late 1970s), and has been developing rapidly. The application of infrared detection technology of temperature measuring gun is of great significance to improve the reliability and effectiveness of electrical equipment, to improve the economic efficiency of operation and to reduce maintenance costs. Is currently in the field of predictive maintenance in the general promotion of a very good means, and can make the maintenance level and the health of the equipment to a higher level.
The use of infrared imaging detection technology can be non-contact detection of equipment in operation, shooting the distribution of its temperature field, measuring the temperature value of any part, according to which a variety of external and internal fault diagnosis, with real-time, telemetry, intuitive and quantitative temperature measurement and other advantages, used to detect the power plant, substation and transmission line running equipment and charged equipment is very convenient and effective.
The method of using thermal imaging camera to detect on-line electrical equipment is the infrared temperature recording method. Infrared temperature recording method is used in industry for non-destructive detection, testing equipment performance and grasp its operating status of a new technology. Compared with the traditional temperature measurement methods (such as thermocouples, different melting points of wax pieces placed on the surface of the object to be measured or in vivo), the thermal imaging camera can be in a certain distance in real-time, quantitative, online detection of the temperature of the hot spot, through the scanning, but also can be plotted in the operation of the equipment in the temperature gradient of the thermal image, and the sensitivity is high, not subject to interference from the electromagnetic field, and easy to use on-site. It can be in -20 ℃ ~ 2000 ℃ wide range with 0.05 ℃ high resolution detection of electrical equipment thermal faults, revealing, such as wire joints or clamps heat, and electrical equipment in the local hot spot and so on.
Infrared diagnostic technology for energized equipment is an emerging discipline. It is the use of energized equipment, the thermogenic effect, the use of special equipment to obtain from the surface of the equipment issued by the infrared radiation information, and then determine the condition of the equipment and the nature of the defects of a comprehensive technology.
