Armature-free explosive magnetic compression generator

Abstract

The invention provides a detonation product conductive solenoid explosive magnetic compression generator, which belongs to the fields of high-power pulse power supplies and magnetic compression. The explosive magnetic compression generator comprises a stator coil, a metal conductive bar and a load; a detonation substance is filled inside the explosive magnetic compression generator; the metal conductive bar is fixedly embedded in the middle of the detonation substance; the explosive magnetic compression generator detonates the detonation substance, the detonation product has conductivity, andthe stator coil, the load, the metal conductive bar and the detonation product form a new current loop so as to capture magnetic flux; and because of the magnetic field freezing effect, the electrical inductance is reduced and the current of the new loop is increased along with the detonation so as to form high-current pulse at the load end.

Description

technical field [0001] The invention belongs to the field of high-power pulse power supply and magnetic compression, in particular to a conductive solenoid type detonation magnetic compression generator for detonation products. Background technique [0002] Magnetic Explosion Compression Generator (MFCG) is a current pulse device designed according to the magnetic field freezing effect. It uses the chemical energy of explosives to drive the deformation of the circuit, compress the magnetic field to do work, reduce the inductance of the circuit, increase the current, and finally convert the chemical energy into electromagnetic energy. The explosive magnetic compression generator can be used as an electromagnetic launcher, plasma focusing, high-power electromagnetic radiation, laser, a power supply for generating a strong magnetic field, and a power supply for exciting a diode to generate a high-current charged particle beam, etc. Due to its single-use characteristics, it is ...

[0004] The disadvantage of traditional single-stage solenoid generators is the low energy output per unit volume

Since the diameter ratio of the armature and the stator coil is limited by the limit radius of the armature expansion, the potential for increasing the initial inductance is limited, and the reasons for jumping turns and poor contact between the armature and the stator coil short-circuit point are likely to cause magnetic flux loss, which also affects The current and energy magnification of the generator
