The infrared window for temperature measurement, also known as an infrared observation window, infrared window, or infrared window, is an optical window that can transmit infrared, ultraviolet, and visible light. It uses an infrared thermal imaging instrument to scan the internal connection positions of high-voltage electrical appliances using infrared radiation. High voltage equipment generally used in sealed environments with voltage levels of 6KV and above (and occasionally 380V voltage levels) is mainly used to detect and monitor the temperature of heating components such as circuit breaker contacts, current transformer contacts, high-voltage switch contacts, and busbar connection points of power equipment in special sealed environments.

When traditional temperature measurement methods such as thermocouples, wireless temperature probes, fiber optic temperature measurement, and grating temperature measurement are unable to measure the temperature of the heat generating components of power equipment in the sealed environment, or when temperature measurement can be achieved but the electronic equipment used in this temperature measurement method has a high probability of causing secondary fault points after a period of use, using an infrared temperature measurement window for temperature measurement becomes a good choice. The infrared temperature measurement window device is installed on the front and rear panels of the cabinet, transformer box, transformer junction box, GIS high-voltage equipment, motor control center, terminal box, and motor junction boxes of power plant fans, pumps, coal mills, and other electrical equipment. On site power operation and maintenance personnel can use infrared temperature measurement instruments such as infrared imagers and infrared thermometers to achieve real-time detection of infrared imaging and temperature measurement of heat generating components of power equipment in a sealed environment under live operation.

The rotating infrared temperature measurement window model specifications include TZYIW-100X, which is a special series of high-end infrared windows with a spherical rotating design that meets the requirements of measurement range and accuracy. Rotating lens can increase the observation angle, keeping the infrared imaging device, infrared temperature measurement window, and the measured object on the same axis. Compared with flat and conventional high-end infrared windows, the crystal observation part can rotate ± 20 °, extending the observation angle and also having electrical verification function; The rotational performance also expands the measurement range of the window and improves the accuracy of the measurement (due to material refraction and other reasons, the same axis measurement is accurate). The disadvantage is that the IK impact protection level, IP protection level, and resistance to electric arc accidents caused by the rotatable structure of the crystal part are reduced, and it is generally not recommended for users to use.
