IDENTIFICATION OF MATHEMATICAL MODELS OF HEAT TRANSFER OF HTSC COILS. 1. TECHNICAL TOOLS AND EXPERIMENTAL TECHNIQUE

This work is devoted to the development of a procedure for the calculation and experimental determination of the thermophysical characteristics of the stator coils of a generator operating using the phenomenon of high-temperature superconductivity. To realize the conditions close to operational ones, temperature regimes of cooling down the coil from 300 to 78 K with subsequent heating to 300 K were implemented during the experiment. The values of the thermophysical characteristics were calculated from the data of temperature measurements at the internal points of the samples. The paper presents a description of the experimental technique.
