EXPERIMENTAL INVESTIGATION OF TUBULAR HALOGEN LAMP THERMAL CONDITIONS
In the present article the authors provide the results of experimental studies to determine thermal conditions tubular halogen lamps (THL) stamps QHT-220-1300 QHT-220-1000-1 with voltage different from nominal (220 V). A thermal imaging camera was used as one of the measuring instruments. The data obtained are highly relevant to date and are widely used in conducting thermal vacuum tests (TVT) on the basis of JSC «SRC «Progress». According to the results of the measurements, an approximation formula was derived to calculate the temperature of the middle part of the quartz bulb at different voltages with an error of not more than 2%. Also, the functional dependence of the body temperature of the filament on the supply voltage is obtained. The analysis of the correctness of the results showed good convergence with the data of open printing, which confirms the reliability of the results. In the light of the latest trends in the creation of digital counterparts of the developed objects, as well as the partial transfer of physical tests to a mathematical experiment, the information obtained will serve as the initial data for the construction of a thermal mathematical model of an infrared radiator of the thermal vacuum complex.
