Kullanım an Kızılötesi Termometre to Teşhis Ekipman Arızalar: Korumalar
Etki meteorolojik koşullar: Sert hava koşullar (yağmur, kar, sis ve kuvvetli rüzgar, vb.) olacak var olumsuz etkiler on the temperature detection of the equipment, and often give false fault phenomena. In order to reduce the impact of meteorolojik conditions, try to conduct detection at night when there is no rain, no fog, no wind and the ambient temperature is relatively stable.
Influence of environment and background radiation: When performing infrared detection of outdoor power equipment, the infrared radiation received by the detection instrument includes not only the radiation emitted by the corresponding part of the tested equipment itself, but also the reflection from other parts of the equipment and the background, as well as direct radiation. Sun radiation. These radiations will interfere with the temperature of the part of the device to be tested, and cause errors in fault detection. In order to reduce the impact of the environment and background radiation, when conducting on-site infrared detection of outdoor electrical equipment, it is best to choose cloudy days or sunsets and evenings when there is no light. This can prevent direct incident, reflected and scattered solar radiation; for indoor equipment, it can be used to turn off the lighting and avoid the influence of other radiation. For highly reflective equipment surfaces, appropriate measures should be taken to reduce the impact on solar radiation and radiation from surrounding high-temperature objects, or change the detection angle to find the best angle that can avoid reflection for detection. In order to reduce the influence of solar radiation and the radiation of the surrounding high temperature background, appropriate shielding measures should be taken during detection, or an appropriate infrared filter should be installed on the infrared measuring instrument to filter out the sun and other background radiation. Select an instrument with appropriate parameters and a detection distance for detection, so that the part of the device under test is within the field of view of the instrument, thereby reducing the interference of background radiation.
