Description
Изобретение относитс к способам тепловых измерений.This invention relates to heat measurement methods.
Известен способ исследовани термоэлектрической .неоднородности проволоки ril , заключающийс в том, что исследуемую проволоку с посто нной скоростью пропускают через миниатюрную электрическую печь и с помощью быстродействующего автоматического компенсатора регистрируют термоэдс, возникающую между концами .проволоки.A known method for studying thermoelectric inhomogeneity of a ril wire is that the test wire is passed through a miniature electric furnace at a constant speed and the thermoelectric power generated between the ends of the wire is recorded using a high-speed automatic compensator.
Известен также способ исследовани термоэлектрической неоднородности 2, при котором измер ют термоэдс на концах проволоки, движущейс через границу раздела двух сред: жидкости и газа, наход щихс при различных температурах.There is also known a method for studying thermoelectric inhomogeneity 2, in which the thermopower is measured at the ends of a wire moving through the interface between two media: liquid and gas, which are at different temperatures.
При этих способах исследовани величина градиента температуры,возникающего в движущейс проволоке, точно не известна и зависит от скорости движени . Этим определ етс невысока точность измерений.With these methods of investigation, the magnitude of the temperature gradient arising in the moving wire is not precisely known and depends on the speed of movement. This determines the low measurement accuracy.
Наиболее близким к предлагаемому вл етс способ определени термоэлектрической неоднородности проволоки в неоднородном температурном поле 3. Согласно способу, величинуThe closest to the present invention is a method for determining thermoelectric non-uniformity of a wire in a non-uniform temperature field 3. According to the method,
термоэлектрической неоднородности электродов термоэлектрических термометров находили по различи м их градуировок в различных температурных пол х, величина градиентов которых точно известна.thermoelectric non-uniformity of electrodes of thermoelectric thermometers was found by the difference of their calibrations in different temperature fields, the magnitude of which gradients are precisely known.
Однако этим способом невозможно определить термоэдс неоднородности на отдельных участках электродной However, using this method, it is impossible to determine the thermopower of the inhomogeneity in certain parts of the electrode
0 проволоки, что снижает точность и производительность процесса исследовани .0 wire, which reduces the accuracy and performance of the research process.
Цед1ью изобретени вл етс повышение тЬчности и производительности The objective of the invention is to increase the productivity and productivity
5 процесса исследовани термоэлектрической неоднородности проволоки.5 of the process of studying thermoelectric non-uniformity of the wire.
Поставленна цель достигаетс тем, что распределению температуры вдоль проволоки придают пилообразный вид, The goal is achieved by the fact that the temperature distribution along the wire is given a saw-like view,
0 например, за счет размещени проволоки петл ми вперед-назад по направлению градиента температуры источника нагрева и регистрируют возникающую термоэдс.0 for example, by positioning the wire loops back and forth in the direction of the temperature gradient of the heating source, the resulting thermoelectric power is recorded.
