Abstract
The aim of the research is the analysis and evaluation of the electromagnetic processes characteristics in the proposed flat rectangular system consisting of a thin solenoid-inductor located between the branches of the bifilar, thin-walled multi-turn coils. The analysis of electromagnetic processes and the obtained estimates of the excited currents are carried out. It is shown that with a minimum gap between the windings of the solenoid-inductor and the bifilar, the time functions of the exciting current and the current induced in the bifilar windings are the same, and the amplitude of the latter is maximum and equal to half the current amplitude in the inductor. It was found that the proposed system has a practical invariance of the time shape and amplitude of the induced current in a wide range of variable geometric parameters. The minimal effect of the fields of induced currents on the processes in the solenoid-inductor and the minimum losses when removing the induced signal from the bifilar windings are noted. Physically, the first is due to the asymmetry of the excited magnetic field relative to the plane of the solenoid-inductor, the second is due to a significant decrease in spurious inter-turn capacitance due to the thinness of the bifilar windings. The obtained results allow us to give practical recommendations when choosing design solutions for elements of new circuits of equipment for magnetic pulse metal processing. References 14, figures 2.
