Description

The invention relates to explosive sources of electrical energy, and more specifically to a device of magnetic magnetic generators generating currents of the order of one hundred million / (SO 10 X 10 Amps) and intended for producing and heating high-temperature plasma, acceleration of plates, cylindrical shells, etc. For generators of this class, the time of energy input to the load of tens of microseconds and power is low. Various power generators with a short time of energy input to the load are known. Such generators have a current-consuming CONT.UR, for a number of explosives for contour deformation and inductively5. load However, the overwhelming number of known generators are capable of generating currents of the order of tens of millions of amps. A sufficiently short operating time at required current values (on the order of 100 million A) can be practically achieved in two types of explosive magnetic generators, where either descending from the cylindrical shell, or dBisuchi (Es to meet each other flat, wide tires) Extender generator) S. A common serious disadvantage of both systems is the complexity of the design, due to The use of bulky focusing devices located outside the explosive charge to create a cylindrical converging or plane detonation wave. The main disadvantage of an explosive magnetic generator with a converging cylindrical shell is a decrease in the radius of the current-carrying surface as the current increases, which leads to large flow losses in the skin layer (near the skin layer), and reduces the output energy. : Another way of compressing the magnetic flux in the tire generator is to initiate charges located on the outer sides of the tires Produced simultaneously from the side, opposite; Burn load 2}. In this way, the plating of the oncoming traffic is added. The main disadvantage of such a bus generator, calculated on a current in the order of 100 ml. A, is the bulk of the bone (characteristic dimensions are calculated with, meters) and the large output of the energy load / (hundreds of microseconds) and, therefore, the output power is low. In addition, the uneven distribution of current across the width of the tires leads to a local field concentration, local overheating of the skin layer and additional flow losses and, consequently, to a decrease in energy and power. . . The aim of the invention is to increase the amplitude of the generated current while simultaneously increasing power. This goal is achieved by the fact that in an explosive magnetic generator containing a current-carrying circuit composed of two conductive plates connected on one side by a conductive jumper, on the other side an indicative load, two charges BB, located on the outer surfaces of the plates, and the initiation system, installed on the jumper side, inductive load connects the plates with each other along the entire perimeter, and then A coping jumper connects them in the center and is installed on the Egg of the symmetry axis of the two plates. In addition, the outer surface of the conductive jumper, the connecting plate of the plate has the shape of two truncated cones with a common base in the plane of the collision of the plates. The proposed device, ceteris paribus, allows one to obtain "/ 10 times more energy compared to the prototype. The connection of the plates along the axis of a metal rod, having the shape of truncated cones, prevents the contour from breaking when the plates slide along the rod. In the absence of a rod taper, large flow losses occur due to a rupture of the contour between the rod and the plate, since the velocity vector of the free surface of the plates is directed away from the axis and forms an angle with it. In FIG. 1 shows the proposed explosive magnetic generator, a general view. . . The generator has a single toroid compression cavity 1, bounded on the sides by two plates 2. Along the perimeter, the plates are connected through a toroidal load 3. On the outer sides of the plates there is a layer of explosive 4. The outer surface of the cross-rod 5 connecting it plate, has the shape of two truncated cones with a common base of e plane of the shock plates. The initial magnetic flux is introduced through the current lead b with a thin insulator 7. At the moment when the required initial current is reached by the action of the explosion products, the current lead closes and the magnetic flux begins to compress. The conductive plates 2 move towards each other and force out the magnetic flux in inductive load.

Example. Plates 2 with a diameter of 400 mm are made of copper sheet 2 mm thick. Along the perimeter of the plate are welded to a copper ring, in which the toroidal volume 3 is inductively loaded) with a diameter of 16 mm. One plate is internally welded to the copper rod 5, having the form of two truncated cones with a common base in the plane of the plates' impact, the other is adjacent to the rod through a thin insulator 7 with a thickness of 0.3-0.4 mm. The same insulator is continued in a coaxial current lead 6, one electrode of which is a copper rod 5, and a cylindrical tube welded to the internal diameter of the plate serves as coal. The distance between the plates is 40 mm. The dimensions of the tapered rod are as follows. Common base with a diameter of 120 mm, upper bases with a diameter of 40 mm. A charge of 4 of 40/60% thick TNT alloy with a thickness of 28 mm was placed close to the outer sides of the plates. The initiation of charges on a ring with a diameter of 40 mm diameter is produced simultaneously by two

detonators through an adapter from explosives.
