Temperature Measurement 5ms rapid respons time Measurement

Influence and countermeasure of Infrared Thermometer motion state. Electrical equipment fault is the current effect caused by the heating fault (conductive circuit fault), heating power is proportional to the square of the load current value, is the voltage effect caused by the heating fault (insulating medium fault), heating power is proportional to the square of the operating voltage.Therefore, the working voltage and load current of the equipment will directly affect the effect of infrared detection and fault diagnosis.The increase of leakage current can cause partial voltage unevenness of high voltage equipment.If there is no loading operation or the load is very low, it will make the equipment failure heat is not obvious, even if there is a serious fault, it is not likely to leak out due to the form of characteristic thermal anomaly.Only when the equipment is operating under rated voltage, and the greater the load, the more serious the heating and temperature rise, and the more obvious the characteristic thermal anomaly of the fault point. So in infrared detection, in order to obtain reliable results, try to ensure that equipment under rated voltage and full load operation, even if you cannot run at full capacity, also want to prepare a running program, so that in the process of testing and inspection before, can make full load operation for a period of time (e.g., 4 ~ 6 h), make the equipment failure parts have enough heating time,And ensure that its surface to achieve a stable temperature rise.In infrared fault diagnosis of electrical equipment, the fault judgment standard is usually based on the temperature rise of the equipment at the rated current. Therefore, the actual operating current during detection is less than the temperature rise of the rated current.

The influence and countermeasures of Infrared Pyrometer equipment surface emissivity, any infrared measuring instrument is to measure the infrared radiation power of electrical equipment surface, to obtain equipment temperature information. In addition, when the industrial infrared pyrometer diagnostic instrument receives the same infrared radiation power from the target, different detection results will be obtained due to the different surface emissivity of the target.That is, the same radiant power with a lower emissivity will show a higher temperature.Because the surface emissivity of the object is mainly determined by the material properties and surface state (such as surface oxidation, coating materials, roughness and pollution state, etc.).Therefore, in order to accurately measure the temperature of electrical equipment with infrared thermography instrument, it is necessary to know the emissivity value of the tested target, and input the value into the computer as an important parameter to calculate the temperature or adjust the emissivity value of the infrared measuring instrument, so as to correct the emissivity of the measured temperature output value.The other two countermeasures to eliminate the influence of emissivity on detection results are: when infrared thermal imager is used for measurement, emissivity should be corrected to find out the emissivity of the surface of the measured equipment components, so as to obtain reliable detection results and improve the reliability of detection.For infrared detection of frequent equipment components, in order to make the detection results have good comparability, can use the method of applying appropriate paint to increase and stabilize its emissivity value, in order to obtain the real temperature of the measured equipment surface.

 

The influence and countermeasures of atmospheric attenuation of industrial pyrometer. Because the infrared radiation energy on the surface of the tested electrical equipment is transmitted to the infrared detection instrument through the atmosphere, it will receive the absorption attenuation of water vapor, carbon dioxide, carbon monoxide and other gas molecules in the atmosphere and the scattering of suspended particles in the air.Equipment radiation energy transmission attenuation with the testing instrument, the distance to the device under test to reduce the equipment failure part and normal part of radiation being measured contrast, also because the target infrared instrument receives the energy reduction, makes the temperature of the instrument displayed is lower than the actual temperature value measured point of failure, resulting in residual or miss diagnosis.This is especially disadvantageous for detecting equipment failure with low temperature rise.With the increase of detection distance, the influence of atmospheric combination will be more and more significant.In order to obtain the accuracy of the target temperature, the following countermeasures must be taken:

A, try to choose in the environment atmosphere is relatively dry and clean season test;

B. Shorten the detection distance as far as possible without affecting safety conditions, and make reasonable distance correction to the temperature measurement results, so as to measure the actual temperature value.

 

The adverse meteorological environment (rain, snow, fog and strong wind, etc.) will adversely affect the temperature detection of the fixed pyrometer, and often give false fault phenomena.In order to reduce the influence of meteorological conditions, the detection should be carried out at night when there is no rain, no fog, no wind and the ambient temperature is relatively stable.

 

The influence and countermeasures of the accuracy pyrometer environment and background radiation. When conducting the infrared detection of outdoor power equipment, the infrared radiation received by the detection instrument includes not only the radiation emitted by the corresponding parts of the tested equipment, but also the reflection of other parts of the equipment and the background, as well as the direct solar radiation.These radiation will cause you to circumvent the temperature of the equipment to be measured, and bring error to the fault detection.In order to reduce the influence of environmental and background radiation, the following countermeasures should be taken:

A. For the on-site infrared detection of outdoor electrical equipment, it should be carried out as far as possible on cloudy days or in the evening when there is no light around sunset.In this way, direct incident, reflected and scattered solar radiation can be prevented, lighting can be turned off for outdoor equipment, and other radiation can be avoided.

B. Appropriate measures should be taken to reduce the impact of solar radiation and surrounding high temperature objects on the surface of the equipment with testosterone reflection.Or change the detection angle to find the best angle to avoid reflection.

C. In order to reduce the radiation impact of solar radiation and the surrounding high temperature background, appropriate shielding measures can be taken during detection, or appropriate infrared filters can be installed on the infrared thermal imaging instrument to filter out the sun and other background radiation.

D. Select the instrument with the appropriate parameters and the detection distance for detection, so that the detected equipment part is filled with the instrument field of view, so as to reduce the interference of background radiation.
