![عکس صفحه اول مقاله: Investigation of a model HTSC transformer with amorphous alloy cores Investigation of a model HTSC transformer with amorphous alloy cores](/preview/png/794271.png)
There are presented the main principles of development of HTSC transformer intended for the individual tests and for investigation within the electrodynamic model of a power network and within the independent electric power installation. The model single-phase transformer incorporates two concentric HTSC windings and circular cores of amorphous alloy and anisotropic steel tapes. It was tested in LN2 medium and permits to evaluate the developed technological processes. Experimental investigations showed amorphous alloys display relatively low level of losses in the magnetic core as compared to anisotropic steel. The combination of epoxy impregnated fiber glass tapes and liquid nitrogen showed acceptable electrical properties of electrical insulation of HTSC windings. The critical current of the windings was close to the critical current of short samples of Bi-2223 tape.
