The aim of the research is to obtain the calculated dependencies for the numerical characteristics of the inductor system, the solenoid winding of which is made in the form of a bifilar with oppositely directed currents. Information on the practical application and calculations of bifilar designs in modern electrical devices for various purposes was analysed. The expediency of using inductor systems with external bifilar coils in the circuit elements of modern metal processing equipment is substantiated. Of particular practical interest is the bifilar as an element of equipment for magnetic pulse metal processing. Calculated ratios are obtained for theoretical analysis and numerical estimates of the characteristics of electromagnetic processes in a cylindrical inductor system, where the inductor is located inside a coaxial solenoid, the winding of which is made in the form of a bifilar with oppositely directed currents. In this case, the excited magnetic fluxes are subtracted outside the windings, which ultimately leads to a decrease in the resulting field, which will be less than the magnetic field of each of the currents separately, which ultimately means a decrease in the coil inductance as an element of the electrical circuit. It is shown that the obtained formulas for fields and currents when changing the sign of the corresponding algebraic term remain valid for the case of unidirectional currents. The found dependences for the voltages and current induced in the bifilar winding are represented by expressions in space that can be converted to explicit time dependences by numerical or analytical methods depending on the calculation conditions for a particular design of the inductor system. The novelty of the present work consists in proposing the idea of constructive execution of the inductor system itself, its physical and mathematical model and obtaining design relationships for the analysis of ongoing electromagnetic processes with numerical estimates of the characteristics of the excited fields. Thus, the proposed design of the inductor system and the resulting calculated dependencies can be used in the design of new equipment for magnetic-pulse metal processing.
Keywords: inductor system, bifilar coil, solenoid, magnetic-pulsed forming, electromagnetic processes.
