Résumé

The paper cites the results of calculation executed using mathematical model plotted for calculation of temperature fields in the structure of high temperature superconductive conductors (HTSC) that is immersed in part into liquid nitrogen. This model allows executing calculation of non stationary heat exchange of a HTSC in liquid nitrogen vapors taking into account axial heat flow appearing at presence of some liquid nitrogen in Dewar vessel or cryogenic tank. The aim of this model is to define the working characteristics of HTSC (current strength, time of current transmission, change of temperature according to radius and height) as well as to estimate the possibility of creation of different level gages for cryogenic liquids on the base of HTSC conductors.
