Detonator explosion closing switch and electric gun composed of same

Abstract

The invention discloses a detonator explosion closing switch, comprising a firing positive plate and a firing negative plate, wherein a high-voltage insulating layer is arranged between the firing positive plate and the firing negative plate; a detonator seat is installed on the firing negative plate; the detonator seat is circular-barrel-shaped, and the bottom of the detonator seat is sealed and sunk inwards to form a firing plane; the firing plane is sunk inwards to form a firing groove with an arc cross section; and the firing groove forms a circular ring. The detonator explosion closing switch disclosed by the invention has the advantages of being simple in structure, low in inductance, resistant to high voltage, high in current-withstanding capacity, free from electrode ablation, and stable and reliable in operation; and due to a parallel plate structure, the detonator explosion closing switch is easily connected with a pulse power device of parallel plate transmission, applied to the device and the like, and compact in structure, and the low-inductance requirement of the device can be met easily, a peak value of discharge current of the device is increased, the rise time of the discharge current is shortened, and the discharge performance of the device is improved.

Description

technical field [0001] The invention relates to a high-power switch in the technical field of pulse power, in particular to a detonator explosion closing switch and an electric gun composed of the same. Background technique [0002] More and more small capacitor bank energy storage, parallel plate transmission, and pulsed power devices with solid dielectric insulation are used in the preparation of nanomaterials in material science, surface spraying, and in the field of shock wave physics to achieve shock and quasi-isentropic compression loading for research Dynamic behavior of materials. The typical experimental device representative of the latter is the electric gun. Its principle is that the pulse power device releases a pulsed high current to act on the metal foil instantly. The polyester film flyer or the composite flyer of polyester film and metal accelerates to several kilometers per second or more than 10km / s, and then hits the target. A high requirement of this ki...
