Energy-efficient methods and means of electrotechnologies for the ultrapure copper smelting in domestic induction installations

New methods and means of mathematical modelling of induction melting processes of copper have been developed. They consist in simultaneous consideration of nonlinear properties of materials and features of three-dimensional geometry of elements of the electrotechnical complex. Means of mathematical modelling of three-dimensional inhomogeneous electromagnetic and thermal fields with strong interconnections, arising in the elements of the electrical complex in the process of induction melting of ultrapure copper and the manufacture of wire rod from it, have been developed.

Methods and tools for structural and parametric identification of electrical systems, processing line for the production of domestic cable with polymer-insulated extra-high voltage

In order to improve the quality of cable products, the idea of a multi-level system of structural and parametric identification of objects of the electrical complex of the technological line for the production of domestic cable with polymeric insulation on ultrahigh voltage is aimed at the main task. Systems guarantee correct, optimal for the main indicator of the quality of the solution of the problem under real conditions of structural, parametric and signal uncertainty and space-time limited data.
