High-strength parallel pulse magnet device

Abstract

The invention belongs to the technical field of electromagnetism, and particularly discloses a high-strength parallel pulse magnet device which comprises a power supply module and a pulse magnet module. The pulse magnet module comprises a magnet unit, a supporting rod and two first reinforcing plates arranged at two ends of the supporting rod respectively. The magnet unit is arranged between the two first reinforcing plates and is electrically connected with the power supply module, and the supporting rod is arranged on a periphery of the magnet unit and is used for limiting and fixing plate layers with different heights so that the plate layers are coaxial and do not generate relative displacement. The magnet unit is composed of n groups of magnet coils connected in parallel. During work,an impedance of the pulse magnet module is reduced to 1 / n of the original impedance by the magnet coils connected in parallel under a condition that the number of turns of the coils is the same, a pulse current with higher intensity is obtained, and a magnetic field with higher intensity is induced. The magnet unit is axially separated through a second reinforcing plate, an axial stress of the magnet unit is shared, and mechanical structural strength of the whole pulse magnet device is improved.

AI Technical Summary

Problems solved by technology

[0004] (1) The pulsed magnets at the present stage are usually wound in the form of a helical tube with a single wire. In order to obtain higher field strength, the number of turns or layers of the coil is often increased, but at the same time the impedance of the magnet is also significantly increased, and the peak value of the magnetic field of the magnet cannot be reached. The expected strength, and the increase of loop damping will make the pulse width of the discharge current significantly wider, which is not conducive to the generation of eddy current effect in the electromagnetic forming process, and the electromagnetic energy conversion rate will be greatly affected, and the insufficient magnetic field strength will seriously limit the observation of physical properties in scientific experiments range

In order to solve such problems, the current method is usually to increase the capacity of the discharge capacitor, but this will significantly increase the cost
