The level of technology

When an electric current passes through a superconducting coil, around which is wrapped around the superconducting element, the lines of magnetic flux of the magnetic field generated in the superconducting coil, passing through the very superconducting coil. For this reason, in particular when using a superconducting element on the basis of bismuth, the magnitude of the current of the electric current will be reduced when increasing the density of magnetic flux, and the flow of electric current will be difficult. Accordingly, in light of the fact that at cryogenic temperatures (liquid helium temperature), because the superconducting element on the basis of bismuth has a significantly higher critical magnetic field than the material on the base metal, suggested that in the I superconducting coil was cooled to cryogenic temperatures by liquid neon or liquid helium (see, for example, patent document 1).

In such a device with a superconducting coil, the amount of current flowing through the superconducting coil can be maintained, even if the magnetic flux density increases.

Disclosure of invention

Problems that must be solved by the invention of

However, in the above-described device with superconducting coil liquid neon or liquid helium is used as coolant for the superconducting coil, and therefore, it becomes difficult to use the refrigerant. Accordingly, although, for example, in a synchronous machine of the inductor type use the device with superconducting coil, the cooling system becomes large, and therefore, the design of all synchronous machines, including the coil, becomes complicated, and the size increase.

The present invention was developed in light of the problems described above, with the purpose of the present invention is to provide devices with superconducting coil, preferably providing a value of electric current flowing to the superconducting coil having a large magnetic flux density, even when the refrigerant using liquid nitrogen, is which is easier to use than liquid helium, as well as in the creation of synchronous machines induction type, which use a device with a superconducting coil.

Part of the solution

In order to achieve the above objective, according to the first aspect of the present invention uses a device with a superconducting coil, comprising a cylindrical container coil, which has an inner circumferential surface and outer circumferential surface; a superconducting coil, which is stored in a cooled container so that the superconducting element is wound on the inner circumferential surface; and a columnar magnetic body, which is fixed to the inner circumferential surface of the container for the coil.

According to the present invention by passing the lines of magnetic flux generated when electric current flows to the superconducting coil through the columnar magnetic body in the axial direction, the lines of magnetic flux passing through the superconducting coil can be reduced. Therefore, even when the superconducting coil is cooled to liquid nitrogen temperature, but not liquid neon, liquid helium or something like that, the current can sufficiently flow to the superconducting coil. At this time, the maximum magnetic flux density is limited to a maximum density of magnetic flux of the columnar magnetic body. However, since the columnar magnetic body is not cooled, the magnetic flux density can be saved.

According to the second aspect of the present invention is applied to the device with superconducting coil corresponding to the first aspect, in which each of the circumferential edge portions of both end surfaces of the columnar magnetic body provided with a flange, the flange is brought into contact with both end surfaces of the container for the coil.

According to the present invention can be obtained greater magnetic flux density than in the case when not provided with flanges.

According to a third aspect of the present invention is applied to the device with superconducting coil corresponding to the second aspect, in which the flanges are formed so that they were narrowed toward both end surfaces of the columnar magnetic body.

According to the present invention can be obtained greater magnetic flux density than in the case where the flanges are of uniform thickness.

According to a fourth aspect of the present invention is applied to the device with superconducting coil corresponding to the first aspect, in which the columnar magnetic body is formed by assembling multiple plate parts along multiple planes, linking the Central axial line or parallel to the Central axial line, between the plate surfaces of the parts adjacent to each other, is provided with an insulator.

According to the present invention adjacent plate parts electrically insulated by insulators. Therefore, even when using a magnetic field generated by a superconducting coil, creating a current in the columnar magnetic body, the current will not pass to the adjacent plate detail. The talk around the Central axial line can be interrupted, and the magnetic flux density may preferably be stored.

According to the fifth aspect of the present invention is applied synchronous machine of the inductor type having a device with a superconducting coil according to the first aspect.

The best way of carrying out the invention

With reference to figures 1 to 7 will be described first variant implementation of the present invention.

Superconducting motor (synchronous machine of the inductor type) 1 according to the present invention is a superconducting motor having a structure with axial clearance, which contains the device 2 with the superconducting coil and the rotary shaft 3 in its center. Superconducting motor includes a pair of stators 7A and 7B from the field excitation, each of which has a yoke 5 made of magnetic material, and the excitation coil 6, protruding from the yoke 5 in the axial direction of the rotary shaft 3 to form the N pole and S pole in the radial direction, and which of the two parties are located so that they are opposite to each other in the direction of the rotational shaft 3; a pair of rotors 11A and 11B, each of which has the inductors 8 N pole located so that they are opposite to the N pole formed the excitation coil 6, and magnetized, and inductory 10 pole S, located so that they are opposite to the S pole formed by the excitation coil 6, and magnetized, with a pair of rotors 11A and 11B are located on two sides so that they are opposite to each other in the direction of the rotational shaft 3; a stator 12 by anchors, which hold between a pair of rotors 11A and 11B and which supports the rotational shaft 3, so that the rotary shaft can rotate and penetrate through it, and in which are located the device 2 with a superconducting coil.

Device 2 with the superconducting coil contains a cylindrical container with refrigerant for heat insulation anchors (container coil) 13 having an inner circumferential surface 13A and the outer circumferential surface 13b, the coil 15 anchors stored in a cooled container 13 with the refrigerant for the heat insulation of the armature, so that the superconducting element on the basis of bismuth or yttrium wound on the inner circumferential surface 13A and a cylindrical columnar magnetic body 16 attached to the inner circumferential surface 13A of the container 13 with the refrigerant for heat insulation anchors. Device 2 with the superconducting coil built at set intervals on the same circumference of the stator 12 by anchor around the rotational shaft 3, so that both end surfaces 16A and 16b of each stancato the magnetic body 16 opposite the inductor 8 N pole and the inductor 10 pole S.

As shown in figure 2, the columnar magnetic body 16 has a construction in which 4 of the columnar parts 16A, 16B, 16C and 16D, is made of a material with high permeability, for example from permendur, silicon steel sheet, iron, permalloy, or something similar, are arranged around the plate parts E to be combined with each other. The columnar magnetic body is thus to penetrate into the body 21 of the rotor, which will be described later. Passing around the circumference edge part, that act both as end surfaces 16A and 16b of the columnar magnetic body 16, provided with a flange 17, protruding in the radial direction from the body part, in which the cylinder is divided by a surface, including its Central axial line. The flange 17 has a larger outer diameter than the outer diameter of the columnar magnetic body 16 so as to be brought into contact with both end surfaces 13C and 13d of the container 13 with the refrigerant for heat insulation anchors.

Accordingly, when assembling the device 2 with the superconducting coil of the first plate part E passed through the Central hole of the container 13 with the refrigerant for heat insulation anchors to insert the body part of the columnar parts 16A, 16B, 16C and 16D around her with both end surfaces of the container 13 with the refrigerant for which teploizolyatsii anchors. Otherwise, for example, columnar parts 16A and 16B have around plate details E by way of penetration from the end surface 13C of the container 13 with the refrigerant for heat insulation anchor, hull and other parts of the columnar parts 16C and 16D is injected to the container 13 from the end surface 13d. In the state in which the cylindrical portion of the columnar magnetic body 16 is fixed to the container 13 with the refrigerant for heat insulation anchor flanges 17 protrude from both end surfaces 13C and 13d of the container 13.

The yoke 5 is made of magnetic material, for example from permendur, silicon steel sheet, iron, permalloy, or something similar, and form a disc shape having a predetermined thickness in the direction of the rotational shaft 3. In the center of the yoke 5 is provided a through hole 5A having such a diameter to penetrate the rotational shaft 3. The container 18 with the refrigerant for heat insulation of the field excitation, which is formed in a ring shape around the rotational shaft 3, are in the direction of the rotational shaft 3 from the inner surfaces of the yoke 5, opposite to each other. The container 18 with the refrigerant for heat insulation of the field excitation is filled with liquid nitrogen and store the excitation coil 6.

The excitation coil 6 is made of a superconducting material on the basis of bismuth is whether yttrium. The excitation coil is stored in the container 18 with the refrigerant for heat insulation of the field excitation so that it was wound around the rotational shaft 3. For this reason, when the excitation coil 6 is excited, the outer circumferential side and inner circumferential side will be divided in the radial direction to create a magnetic pole.

As shown in figure 3, each pair of rotors 11A and 11B has a body 20 of the rotor, made of a nonmagnetic material, such as plastic, reinforced with fiberglass, or stainless steel, and holds the rotary shaft 3 through the mounting holes 20A made in its center. In the outer surface of the body 20 of the rotor opposite to the yoke 5, around the rotational shaft 3 in a ring shape formed Zuzana groove 11a, which is in engagement with the coil 6 of the excitation. Many retaining concave portions 11b and 11C formed in the circumferential direction in such a manner as to surround satanae hole 11a and store the inductors 8 pole N or inductors 10 pole S.

As shown in figure 4, the inductors 8 N pole is made with one end surface 8A, which is formed in a curved shape, so that it was opposite the container 18 with the refrigerant for heat insulation of the field excitation from the outside or from the inside in the radial direction, and the other end surface is STU 8b, which is formed in the shape of an elliptical plate, so that it was long in the circumferential direction of the body 20 of the rotor and was short in the radial direction, when the opposite columnar magnetic body 16, or actually in the form of a disc. As shown in figure 5 and 6, in General, there are four coils 8 poles N, each of which is symmetrical relative to the center of the body 20 of the rotor, with penetration in the direction of the rotational shaft 3. In this case, one end surface 8A of each inductor 8 N pole is positioned in such a way that it was opposite in the position of creating the N pole coil 6 excitation when accessing satanay the groove 11a. The other end surface 8b is located so that it was opposite to the coil 15 of the anchor.

As shown in Fig.7, the inductors 10 pole S is made with one end surface 10A, which is formed in a curved shape, so that it was opposite the container 18 with the refrigerant for heat insulation of the field excitation from the outside or from the inside in the radial direction, and the other end surface 10b, which is formed in the shape of an elliptical plate, so that it was long in the circumferential direction of the body 20 of the rotor and was short in the radial direction, when the opposite columnar magnetic body 16, or actually in the form of di is SC. As shown in figure 5 and 6, in General, there are four coils 10 pole S, each of which is located at the position symmetrical with respect to the center of the body 20 of the rotor, and differs in phase by approximately 90 degrees relative to the inductor 8 N pole, with penetration in the direction of the rotational shaft 3. In this case, one end surface 10A of each of the inductor 10 of the S pole is located so that it was opposite to the position of formation of the S pole coil 6 excitation when accessing satanay the groove 11a. The other end surface 10b is positioned in such a way that it was opposite to the coil 15 of the armature. The inductors 8 N pole and the inductors 10 S pole made of a magnetic material, for example from permendur, silicon steel sheet, iron, permalloy or something similar.

The stator 12 from the anchor has a body 21 of a stator made of a nonmagnetic material, such as plastic, reinforced with fiberglass, or stainless steel. In the center of the body 21 of the stator is a through hole 21A, through which the rotational shaft 3. In the body 21 of the stator at set intervals on the same circumference built six devices 2 with the superconducting coil.

Through wiring 22 DC excitation coil 6 is connected to the source 23 DC. In addition, through the your wiring 25 AC coil 15 of the armature is connected to the source 26 AC. Meanwhile, the cooling unit 28, in which the refrigerant using liquid nitrogen, through the cooling pipe 27 is connected to the container 18 with the refrigerant for heat insulation of the field excitation and the container 13 with the refrigerant for heat insulation anchors. The cooling unit 28 connected to a source of excitation power (not shown) for cooling and circulation of liquid nitrogen.

Next will be described the operations of the device 2 with the superconducting coil according to this variant implementation and superconducting motor 1 having a device with a superconducting coil.

First, operate the cooling unit 28, to apply liquid nitrogen to the container 18 with the refrigerant for heat insulation of the field excitation and the container 13 with the refrigerant for heat insulation anchors through the cooling pipe 27. Each of the coil 6 and the initiation of the coil 15 anchors located in the container 18 with the refrigerant for heat insulation of the field excitation and the container 13 with the refrigerant for heat insulation anchors, cooled down so that they were in the superconducting state.

Next to each excitation coil 6 from source 23 DC serve DC. At this time, depending on the direction of direct current, for example, the N pole is formed outward in the radial direction the AI coil 6 excitation, and the S pole is formed inward in the radial direction in the stator 7A side of the field excitation. Accordingly, the N pole is sent to the other end surface 8b of the inductor 8 N pole, which is opposite to the stator 12 from the anchor. On the other hand, the S pole is sent to the other end surface 10b of the inductor 10 of the S pole, which is opposite to the stator 12 from the anchor. The same magnetic poles are formed depending on the direction of the DC current in the stator 7B side of the field excitation, while the poles N and S refer to the other end surfaces 8b and 10b, respectively, of the inductor 8 N pole and the inductor 10 pole S.

In this state, three-phase alternating current fed to the coil 15 of the anchor from the source 26 AC. At this time, due to the difference between the three phases of the rotational magnetic field rotating around the rotational shaft 3, is created in the coil 15 of the armature. Moreover, the lines of magnetic flux pass through the columnar magnetic body 16 in the axial direction, and thus the magnetic poles different from each other, alternately occur in accordance with the AC cycle on both the end surfaces 16A and 16b of the columnar magnetic body 16. The rotational magnetic field repeats the action of the retraction and repulsion between the other end surfaces 8 and 10b of the inductor 8 N pole and the inductor 10 pole S, to create the effect of rotation around the line of the rotational shaft in the same direction between a pair of rotors 11A and 11B, and therefore, the rotational shaft 3 will make a rotation.

In this case the superconducting motor 1, as the device 2 with the superconducting coil includes a columnar magnetic body 16, the lines of magnetic flux passing through the coil 15 of the anchor, can also pass through the columnar magnetic body 16 to loosen the lines of magnetic flux passing through the coil 15 of the armature. Accordingly, even if the coil 15 of the anchor is cooled to liquid nitrogen temperature, but not liquid neon or liquid helium, to the coil 15 of the anchor can pass enough current. At this time, the maximum magnetic flux density is limited to a maximum magnetic flux density of the columnar magnetic body 16. However, since the columnar magnetic body 16 is not cooled, the magnetic flux density can be saved. In addition, since both the end faces 16A and 16b of the columnar magnetic body 16 provided with a flange 17 may be received increased magnetic flux density.

Furthermore, since the pair of rotors 11A and 11B, the coil is not only the excitation coil 6 and the coil 15 anchors located in the stator, can be powered by electricity and cooled the design of the electrical system and cooling system can be simplified. In this case, by engagement of the coil 6 excitation with satanay groove 11a of the body 20 of the rotor excitation coil 6 may be located in the body 20 of the rotor so as to be surrounded by the inductor 8 N pole and the inductor 10 of the S pole in the radial direction. Accordingly, when the thickness of each of the stator 7A and 7B from the field excitation in its axial direction can be accounted for only by the thickness required for the yoke 5, without regard to the amount of protrusion of the coil 6 of the excitation to the rotor 11A or 11B, and its length in the direction of the rotational shaft 3 can be reduced.

Next, with reference to Fig will be described a second variant implementation of the design.

The same components as in the above-described first embodiment, the structure denoted by the same items, their description will not be given here. The second variant of implementation differs from the first variant the fact that the flanges 32 provided in the columnar magnetic body 31 of the device 30 with the superconducting coil according to this variant, narrowed toward both end surfaces 31A and 31b of the columnar magnetic body 31, and thus is formed the inclined surface 32A. The rest of the design of the superconducting motor 33 having the device 30 with the superconducting coil, the same as in the first embodiment.

Next will be described the operations of the device 30 is of a superconducting coil and a superconducting motor 33.

As in the first embodiment, each of the coil 6 and the initiation of the coil 15 of the anchor is cooled to a state of superconductivity and then to the excitation coil 6 serves DC. The N pole and the S pole is sent to the other end surfaces 8b and 10b, respectively, of the inductor 8 N pole and the inductor 10 pole S.

In this state, three-phase alternating current fed to the coil 15 of the anchor from the source 26 AC. At this time, as described above, by the difference between the three phases in the coil 15 of the armature creates a rotating magnetic field rotating around the rotational shaft 3. In this case, the lines of magnetic flux pass in the axial direction through the columnar magnetic body 31. Because the flanges 32 is additionally provided with inclined surfaces 32A, lines of magnetic flux pass through the inclined surface 32A of the flanges 32 in addition to both end surfaces 31A and 31b.

This creates a rotating magnetic field having a greater magnetic flux density than in the first embodiment. Between the other end surfaces 8b and 10b of the inductor 8 N pole and the inductor 10 pole's repeated actions of attraction and repulsion to create a force of rotation around the line of the rotational shaft in the same direction between a pair of rotors 11A and 11B, and therefore, the rotational the al 3 will rotate.

In the case of the device 30 with the superconducting coil and a superconducting motor 33, as in the first embodiment can be obtained greater magnetic flux density than in the case when the flanges 32 have a uniform shape.

Next, with reference to figure 9 will be described a third variant embodiment of the invention.

The same components as in the above-described embodiment, the structure denoted by the same items, their description will not be given here. A third option implementation differs from the first variant the fact that the columnar magnetic body 36 of the device 35 with the superconducting coil according to the present invention is formed by assembling multiple plate parts 37A-37G along multiple planes including the Central axis line With or parallel to the Central axial line, and between the surfaces of the plate parts 37A-37G, adjacent to each other, is provided with an insulator 38.

Next will be described the operations performed by the device 35 with the superconducting coil and a superconducting motor 40, having a device with a superconducting coil. In addition, in this embodiment, the rotational shaft (not shown) is put into rotation by performing the same operations as the operations related to the device 2 with the superconducting coil and a superconducting DWI is on of the motor 1 according to the first variant implementation. In this case, the plate parts 37A-37G electrically insulated by insulators 38. Accordingly, even when using a magnetic field generated in the coil of the armature (not shown)will be provided by the electric current in the columnar magnetic body 36, the current around the Central axial line is interrupted between the plate parts 37A-37G. Accordingly, in the case of the device 35 with the superconducting coil and a superconducting motor 40 preferably can be stored magnetic flux density of the magnetic field generated by the coil anchor.

The technical scope of the present invention is not limited to the above-described variants, without deviating from the essence and scope of the present invention can be made various changes. For example, in the above-described embodiments, the implementation of the synchronous machine of the inductor type represents a superconducting motor. However, the synchronous machine of the inductor type can be used as an electric generator, which generates electrical energy through rotation of the rotational shaft 3.

In addition, in the above-described embodiments, the implementation of the columnar magnetic body 16 provided with flanges 17, but its end surface may not have flanges. In this case, you do not want columnar magnetic t the lo was divided into columnar or plate details. Further, when the columnar magnetic body and the container 13 with the refrigerant for heat insulation anchors are fixed to each other, may be provided with a locking element to secure their connection.

In addition, in the superconducting motor 1 according to the first variant implementation of the yoke 5 of each of the stator 7A and 7B from the field excitation provide the excitation coil 6, which includes a superconducting element. However, instead of 6 excitation coil, inductor 8 N pole and the inductor 10 of the S pole pair of the rotor 42 A and 42, the superconducting motor 41 may be provided with a permanent magnet 43, as shown in figure 10. In this case, the permanent magnet 43, equal in size and located in a similar way to the other end surfaces 8b and 10b of the inductor 8 N pole and the inductor 10 pole S according to the first variant implementation, is located in the body 45 of the rotor so that it was opposite to the device 2 with a superconducting coil. The body 45 of the rotor includes the same magnetic body and the yoke 5 of the stator 12 by anchor according to the first variant of implementation, and is connected to the rotational shaft 3.

Superconducting motor 41 has the same device 2 with the superconducting coil, as in the first embodiment. Accordingly, in a state in which three-phase alternating current fed to the coil 15 of the armature at which trojstva 2 with superconducting coil from a source 26 AC the rotational shaft 3 will rotate through the same operation as in the case of the superconducting motor 1 according to the first variant of implementation, in which a constant current flows to the coil 6 of the excitation. In addition, there can be obtained similar to the findings according to the first variant implementation. Next, as shown in figure 11, the superconducting motor 46, containing a permanent magnet 43 may have a device 30 with the superconducting coil according to the second variant implementation.

Additionally, in the case of the above-described embodiments, the present invention uses an internal type rotor in which the rotational shaft 3 is connected with the centers of the pair of rotors rotating with a pair of rotors, but this invention is not limited. For example, in the present invention can be provided with a synchronous machine, induction type with an outer rotor in which a shaft portion located at its center, is a fixed shaft, and the outer circumference connected to the pair of rotors.

In addition, the number of combinations of N pole inductors and inductors pole S, and armature coils is not limited to the above combination. For example, the number of inductors pole N and the number of inductors pole S may be two of each, and the number of coils of the armature can be Rav is about three. Further, as the number of inductors pole N and the number of inductors pole S can be equal to eight, and the number of armature coils may be equal to twelve.

Separate turns (Wi) of the coil winding must be made from at least one tape of a superconductor (5), particularly with superconducting material with high critical temperature Tc, whose narrow side (5a) faces the pipe-like lateral surface (Mf). To prevent inadmissible mechanical loads on the conductor when forming the winding, turns (Wi) in the saddle shape must have perimetre (U) respectively, which remains virtually unchanged compared to that in a flat coil.

EFFECT: efficient use of superconducting material from ready tape-like conductors with compact arrangement of windings; small diametre can be achieved of the area forming the pipe-like lateral surface.
