Description

Technical field

The utility model relates to magnetic pulse generators controlled by the energy of the explosion, and can be used in the electric power industry, for example, to generate test pulses for lightning resistance of overhead power lines.

State of the art

Known adopted for the prototype, explosive magnetic current pulse shaper according to ed. testimonial. SU 1248479 IPC Н01H 39/00, Н03К 3/53, publ. 1995 year

The prototype contains a condensed explosive (BB) liner coaxially covered by a spiral winding, and an explosion-controlled disconnector with an explosive charge and a bursting conductor. Blasting the explosive charge of the circuit breaker is initiated by an external means that synchronizes the operation of the liner and the circuit breaker.

The disadvantage of the prototype is the need to provide external synchronization of the operation of the circuit breaker with the required delay relative to the moment of detonation of the condensed explosive liner. This complicates the management of the device and reduces the reliability of its operation.

Utility model creature disclosure

Achievable technical result - simplification of control of the device and increasing the reliability of its operation due to internal self-synchronization of undermining the explosive charges of the liner and disconnector.

The object of the utility model is an explosive magnetic current pulse generator containing a liner with a condensed explosive, coaxially covered by a spiral winding, and an explosion-controlled disconnector with a charge of an elastic explosive and a bursting conductor, while the charge of an elastic explosive is placed with the possibility of undermining it by detonation of the condensed explosive at output end of the liner.

This allows you to get the above technical result.

The utility model has a refinement development, consisting in the fact that the rupture conductor is made in the form of a spiral of aluminum foil and that the charge of the elastic explosive is made with the possibility of destruction of the rupture conductor simultaneously in several sections.

Utility Model Implementation

Figure 1 presents an example implementation of a utility model, taking into account its development.

The device contains:

- liner 1 with condensed explosive 2, which is a conductive tube filled with explosives;

- spiral winding 3, coaxially covering the liner 1.

- explosion-controlled disconnector 4, which includes a charge 5 of elastic explosive and a bursting conductor 6, made, for example, in the form of a spiral of aluminum foil.

The charge 5 is placed with the possibility of detonation by detonation of a condensed explosive 2 at the output end 7 of the liner 1 and is configured to simultaneously destroy the conductor 6 in several sections.

In addition, figure 1 shows: a capacitive drive 8, a key 9, a load 10 connected to the output terminals 11 of the generator, and a fuse 12 mounted on the input end 13 of the liner 1.

The device operates as follows.

A charged storage device 8 (its charge circuits are not shown in FIG. 1) is connected by a key 9 to a spiral winding 3, which performs the function of an inductive storage device storing initial magnetic energy. In this case, the current load circuit includes: capacitive storage 8, winding 3, load 10, rupture conductor 6 and conductive tube of liner 1. At the moment of discharge of capacitor 8 to zero voltage, fuse 2 is initiated by fuse 12 from input end 13 of liner 1 . When this discharged drive 8 is removed from the current circuit, and the liner 1 under the action of the detonation products of the explosive 2 expands. The movement of the blast wave along the liner 1 (from left to right in FIG. 1) provides sliding along the turns of the winding 3 of its electrical contact with the tube of the liner 1 and can be illustrated by moving from left to right along the winding 3 of the slider 14 shown in dashed lines in FIG. In this case, the spiral winding 3 is deformed, and its magnetic flux is displaced to the load 10. At the end of the deformation process, the current in the load 10 reaches its maximum value, and the axial detonation of the charge 2 of the condensed explosive, reaching the output end 7 of the liner 1, initiates the detonation of the charge 5 of the elastic explosive in composition of the circuit breaker. Charge 5 is made in the form of elastic explosive rings, which, when detonated, form a diverging cylindrical detonation wave, under the influence of which the conductor 6 is destroyed simultaneously in several sections and breaks the current load circuit.

As a result of the described process, a current pulse with a short trailing edge is formed in the load 10, which can be used, for example, for testing lightning resistance overhead power lines.

The described device design has the property of internal self-synchronization of the liner 1 and the explosion-controlled breaker 4, which allows you to control the breaker without using external synchronization means and, thereby, increase the reliability of the device.
