Subjects of research: multirangc current transformers (TT).
Purpose of work: development and study multirange transformer of the current with extended functional possibility and perfected dynamic characteristic for managerial systems device supply railway.
Methods of research: theories electric and magnetic circuits and electromagnetic field, inaccuracy, cncrgolnformation and morphological methods search construction sensor and device of the parametric structured schemes (PSS) with using the computer technology, as well as experimental methods of the studies.
The results obtained and their novelty: is designed new designs multirange TT of the current with extended functional possibility and perfected dynamic characteristic, protected patent RUz, and their mathematical models; the way of the reduction of inaccuracy multirange TT under their work but connecting mode.
Practical value: designed TT multirangc has an extended functional possibility and comparatively pinpoint accuracy transformation when functioning (working) in connecting mode. Designed mathematical models, allow on stage of the designing multirange TT to research them in steady-state dynamic mode.
Degree of embed and economic effectivity: designed multirange TT is introduced and production process on attractive substation “Transport” distances of supply “Xavast” Herewith, the annual economic effect forms 5,3 million so’ms.
Field of application: results of the work can be arc broadly used at development multirange TT, intented for managerial systems and checking state of working device of supply on rail-freight traffics and other branch public facilities.
