The invention relates to electrical engineering and can be used in electric generators and other electric machines used in various fields of human economic activity. The diamagnetic-thermal method for generating a variable emf. Is that a "normal zone" surrounded by a superconducting "diamagnetic barrier" is created, retained and moved in a superconducting stator layer equipped with an electric machine by successively heating certain regions of said superconducting layer to a temperature violating superconductivity and diamagnetism. The working magnetic flux passing through the "normal zone" is moved by moving said "normal zone". Power magnetic lines of the moving working magnetic flux, crossing the conductors of the fixed winding of the stator fixed to the magnetic circuit, induce in them an emf. The working magnetic flux of the electric machine can be created by an annular electric current flowing in the superconducting layer of the stator around the "normal zone" or other source. The technical result is to increase reliability, because The devices that realize this method do not have moving parts, but also in ensuring the universality of power supply due to the possibility of using both heat energy and other types of energy that are easily converted into heat.

DESCRIPTION OF THE INVENTION

The invention relates to the field of electric power engineering and can find application in electric generators and other electric machines used in various fields of human economic activity.

Methods for generating an emf are known. , Based on the change in the magnitude of the magnetic flux penetrating the closed loop. They are widely used in electric generators of both AC and DC.

The closest to the proposed is the method used in alternating current generators , consisting in the fact that the stator's stationary winding is acted upon by the rotating magnetic field of the rotor. In this case, the turns of the stator winding are intersected by the magnetic flux of the rotor changing in the direction and the variable emf is inducted in them. ( VY Lomonosov and KM Polivanov, Electrical Engineering, Moscow, 1949, pp. 173-174 ).

A disadvantage of this method is that a rotating rotor is used to create a rotating magnetic field. This makes power generators operating on this principle less reliable than electric machines that do not have moving parts.

The task, the solution of which is directed to the invention, is to increase the possibilities and expand the field of application of electric generators and other electric machines.

The technical result of the invention is an increase in the reliability of electric generators and other electric machines and the possibility of their activation by different types of energy.

The solution of the above problem is achieved by the method of generating a variable emf. , Consisting in the fact that the immovable winding of the electric machine fixed to the stator magnetic circuit is acted upon by a moving working magnetic flux whose magnetic lines cross the turns of the stationary winding and induce a variable emf in them. The moving working magnetic flux closing through the "normal zone" of the superconducting layer of the stator of the electric machine is driven by a moving superconducting "diamagnetic barrier" surrounding the "normal zone" and the "normal zone" is created and moves along the superconducting layer of the stator of the electric machine by means of a moving heat spot , Which temporarily breaks (with subsequent restoration) the diamagnetic and superconducting properties of the heated regions of the superconducting layer of the stator of the electric machine.

DIAGNOSTIC-THERMAL METHOD OF GENERATION OF A VARIABLE EMULATOR Patent of the Russian Federation RU2214670

The drawing shows a working model demonstrating the operation principle of devices implementing the method. The sleep consists of a stator whose superconducting layer is made in the form of an immovably standing plate 1 in the superconducting state (in the figure, the upper left part of the plate is cut out). To create a "normal zone" 9 traveling along line 2, there is a heat radiator 3 radiating a heat ray 4. Winding 6 is fixed to the magnetic circuit 5.

A method for generating a variable emf. Is that the moving working magnetic flux 7 generated by the ring electric current 8 flowing in the superconducting layer of the stator 1 around the "normal zone" 9 is closed through the magnetic circuit 5. When the "normal zone" 9 moves along the superconducting layer of the stator 1 along the line 2 Along with the "normal zone", the moving working magnetic flux 7, which is surrounded by a superconducting "diamagnetic barrier", moves, since the superconducting "diamagnetic barrier" (the section of the superconducting stator layer surrounding the "normal zone" and possessing superconducting and diamagnetic properties), serving as an obstacle to magnetic Fields, will carry him away with him. In this case, the moving working magnetic flux will intersect the winding 6 fixed to the magnetic circuit 5 by means of magnetic magnetic lines, as a result of which an emf will be induced in the winding. Having reached a certain endpoint, the "normal zone" will change the direction of travel to the opposite and moving working magnetic flux 7 will cross the winding 6 in the opposite direction, inducing the emf in it. Reverse sign. If the cycle is repeatedly repeated, the variable emf will be inducted in the winding, the frequency and amplitude of which can be varied within wide limits.

The annular electric current 8 flowing in the superconducting layer of the stator 1 around the "normal zone" 9 can be obtained as follows. In a superconducting state (cooled to a temperature below the T-critical ) superconducting layer of the stator 1, a "normal zone" 9 (not having superconducting and diamagnetic properties) is formed in a superconducting layer of the stator 1 cooled to a temperature above the T-critical region, . Next, take the ring from the conductive material and bring one of the poles of the permanent magnet closer to the center of its circumference. Since the magnetic lines of force cross the conductor, the emf will be induced in it. And an annular current will flow that will quickly die out. Thereafter, the conductive ring together with the magnet is applied to the superconducting layer of the stator 1 in such a way that it has electrical contact with the superconductor along the entire circumference, and the "normal zone" 9 is located opposite the opening of the ring. A superconductor, possessing diamagnetic properties, will not let the magnetic field into itself and the magnetic lines of force are largely concentrated in the conducting ring. Then the magnet is removed. Power magnetic lines, crossing the conductor, will cause in it an emf. And will cause a ring electric current. Since the conductor ring has electrical contact with the superconductor all along the entire circumference, and the electric current flows along the path of least resistance, the ring current induced in the conducting ring will almost instantaneously move to the superconductor surrounding the "normal zone" on the superconducting layer of the stator. After this, the conductive ring is separated from the superconducting stator layer. Since the conductor has no electrical resistance, the annular current 8 will circulate around the "normal zone" 9 without fading.

The "normal zone" 9 is created, held and moved along the superconducting layer of the stator 1 by heating certain regions thereof with the thermal beam 4 to a temperature above the T-critical one. At the same time, the heated region jumps in its properties. Superconductivity and diamagnetism in it disappear.

An indispensable condition for the device to function is the constant maintenance of the superconducting layer of the stator 1 in the superconducting state (in the described case the process must take place in a medium with a temperature below T-critical). After moving the heat spot, the temperature of the region heated to this point should drop below the T-critical value. Superconducting and diamagnetic properties should be restored in it. And it is necessary that the "normal zone" does not border the edge of the superconducting stator layer. Otherwise, the superconducting "diamagnetic barrier" surrounding the "normal zone" will explode.

The "normal zones" on the superconducting layer of the stator of the electric machine can be several. The moving working magnetic flux, in addition to the ring electric current, can be created by other methods, for example, by means of a permanent or electromagnet. In this case, the moving working magnetic flux is surrounded by a superconducting "diamagnetic barrier" as follows. A "normal zone" bordering the edge is created on the superconducting layer of the stator of the electric machine. A moving working magnetic flux is introduced into this zone, after which the section of the "normal zone" adjacent to the edge is again transferred to the superconducting state. The superconducting "diamagnetic barrier" surrounding the "normal zone" with the moving magnetic flux passing through it closes. Further, moving the "normal zone" along the superconducting layer of the stator, we will also move the supra-conducting "diamagnetic barrier" surrounding it, which will entrain the moving working magnetic flux behind it.

Since a thermal spot creating a "normal zone" can be obtained in various ways (a thermal radiator or a radiator of a different kind of energy that is converted upon contact with a superconducting layer into heat, heat-insulating elements successively included on the superconducting layer, etc.) Implementing the method, can eat various types of energy.
