For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
The superconducting technology has wide application prospect, and how to realize the control and adjustment of superconducting current is a popular research direction in recent years; at present, the control and adjustment of superconducting current mainly comprises the control of the magnitude and direction of the current; current control means include: the direction of the current is regulated by changing the rotation direction of the rotary flux pump disk 4, but since the permanent magnet disk 4 has rotational inertia, it is difficult to realize high-precision control using a method of regulating the superconducting current direction by changing the rotation direction of the rotary flux pump disk 4; the superconducting current is regulated by regulating the rotating speed, the magnetic flux gap, the geometric shape of the annular magnetic yoke, the width of the stator line and the like, but the load current is changed by changing the structure due to the regulation of the magnetic flux gap, the geometric shape of the annular magnetic yoke and the width of the stator line, so that certain inoperability exists in practical application.
Therefore, the method has important significance for the application and popularization of the superconducting technology on the premise of not changing the structure to control the direction and the magnitude of the superconducting current. In view of this, the present invention provides a concept to solve the above-mentioned problems.
Firstly, the present invention provides a method for controlling a magnetic flux pump system, in which a constant background magnetic field with continuously adjustable direction and intensity is applied to a superconducting stator 1, and a dc magnetic field is generally selected as the background magnetic field, so that the magnitude and direction of an ac traveling wave generated by a rotary magnetic flux pump are influenced by the constant dc magnetic field. Correspondingly, the direction of the alternating current traveling wave is changed by changing the magnetic field direction of a constant direct current magnetic field, so that the direction of the pumping current is changed; the magnitude of the alternating current traveling wave is changed by changing the intensity of the constant direct current magnetic field, so that the magnitude of the pumping current is changed. By this method, the change of pumping current can be realized without contact and without changing the structure of the magnetic flux pump system, which enables the superconducting system to be applied to more scenes.
According to the method, the invention also provides a corresponding device for controlling the superconducting current, which is characterized in that the variable background magnetic field generated by the variable magnetic field device is used for influencing the alternating current traveling wave generated by the rotary magnetic flux pump, and the intensity and the direction of the background magnetic field are changed to control the magnitude and the direction of the superconducting current.

In this embodiment, the superconducting stator 1 is connected to the superconducting coil 2 to form a closed loop; in this embodiment, the superconducting coil 2 is a single-wire double-cake superconducting coil, and this embodiment only shows the case of having one single-wire double-cake superconducting coil, and the parameters and the number of the single-wire double-cake superconducting coils can be adjusted according to the actual situation, so that the description is omitted.
At present, materials of the superconducting stator 1 and the superconducting coil 2 are more selected, the application preferably adopts a ReBCO strip, the superconducting coil 2 obtained by winding the ReBCO strip is provided with two strip line ends, one strip line end is used as an inlet of current, the other strip line end is used as an outlet of current, two ends of the superconducting stator 1 are respectively connected with the strip line ends, so that the superconducting stator 1 and the superconducting coil 2 form a closed loop, when a magnetic flux pump generates a travelling wave magnetic field on the surface of the superconducting stator 1, the travelling wave magnetic field can couple flux quanta in the superconducting stator 1, and when the travelling wave magnetic field advances along one direction, direct current is generated at two ends of the superconducting stator 1, and then direct current is generated in the closed loop.
The superconducting stator 1 is positioned between the rotary magnetic flux pump and the variable magnetic field generating device; the variable magnetic field generating device comprises a direct current coil 3 and an adjustable direct current power supply for supplying power to the direct current coil 3; the superconductive stator 1 is made of ReBCO strip material, so the superconductive stator 1 is in a strip shape, and in the embodiment, the width is 12mm, and the thickness is 220um; neglecting the thickness, taking any one of the two surfaces of the superconducting stator 1 as a first surface, and taking the other surface as a second surface; as shown in fig. 3, the first surface is in contact with the surface of one end of the dc coil 3; the dc coil 3 is generally cylindrical in shape, and as shown in the present embodiment, the dc coil 3 may be effective even if it is a racetrack shape, as is understood by the present invention. A gap of about 1mm is provided between the second surface and the magnetic disk 4, and the size of the gap can be adjusted according to actual conditions.
As shown in fig. 4 and 5, the optimal arrangement positions of the magnetic disk 4, the superconducting stator 1 and the dc coil 3 are shown, wherein the superconducting stator 1 passes through the center or the center of the dc coil 3, and both ends of the superconducting stator 1 are symmetrical with respect to the magnetic disk 4.
Since the superconducting coil 2 and the superconducting stator 1 in the present embodiment adopt a horizontal layout manner, in this embodiment, both ends of the superconducting stator 1 have bending portions, so that the superconducting coil 2 is parallel to the surface of the superconducting stator 1, and as shown in fig. 1, the controllable magnetic flux pump system is divided into three layers, namely, a magnetic flux pump, the superconducting coil 2, the superconducting stator 1 and a direct current coil 3.
Secondly, as shown in fig. 1, 2 and 6, the rotary magnetic flux pump in this embodiment includes a magnetic disk 4, a connecting rod 5 and a motor 6, a rotating shaft of the motor 6 is connected with the connecting rod 5 and is coaxial with the connecting rod 5, the magnetic disk 4 is fixedly sleeved on the connecting rod 5, a fixing seat 7 is embedded in the center of the magnetic disk 4, the fixing seat 7 is coaxial with the magnetic disk 4, the axial length of the fixing seat 7 is greater than that of the magnetic disk 4, a fixing through hole 9 is arranged in a part of the fixing seat 7 which is not contacted with the magnetic disk 4, and the fixing through hole 9 penetrates through the fixing seat 7.
In addition, a plurality of grooves are uniformly formed in the outer peripheral surface of the magnetic disk 4, preferably, 8 grooves are formed in the outer peripheral surface of the magnetic disk, and each groove is embedded with a permanent magnet 8, so that the magnetic disk 4 can continuously generate a traveling wave magnetic field when rotating.
Since the speed at which the magnetic disk 4 rotates needs to be controlled, the rotary magnetic flux pump in this embodiment further includes a frequency converter for controlling the motor 6; if the motor 6 is a three-phase motor 6, the frequency converter is a three-phase frequency converter.
In embodiment 1, since the closed loop formed by the superconducting stator 1 and the superconducting coil 2 needs to be kept in a low temperature state to realize a superconducting state, the closed loop formed by the superconducting stator 1 and the superconducting coil 2 needs to be placed in a low temperature environment, including a low temperature environment realized by liquid nitrogen immersion, refrigeration by a refrigerator, liquid helium or helium cooling, and the like. For example, when the horizontal layout mode is adopted, the superconducting coil 2, the direct current coil 3 and the superconducting stator 1 are immersed in a 77K liquid nitrogen environment in operation, and a rotary magnetic flux pump consisting of the motor 6, the connecting rod 5 and the magnetic disk 4 is placed in the air.
In embodiment 2, referring to fig. 2, in the controllable magnetic flux pump system provided in fig. 2, a vertical layout mode is adopted between the superconducting coil 2 and the superconducting stator 1, which is the biggest difference from the embodiment in that the superconducting stator 1 has no bending portion, an annular closed loop formed by the superconducting stator 1 and the superconducting coil 2 is parallel to the axial direction of the dc coil 3, and the dc coil 3 is located in the annular closed loop; when the embodiment works, the superconducting state can be realized only in a low-temperature environment; for example, when cooling with liquid nitrogen, the magnetic disk 4 and part of the connecting rod 5 need to be in a 77K liquid nitrogen environment due to the structural differences in this embodiment.
In embodiment 3, in addition to embodiment 1 or embodiment 2, a hall element may be further provided, where the hall element is disposed between the first surface of the superconducting stator 1 and an end surface of the dc coil 3, and a gap of about 2mm is formed between the first surface and an end surface of the dc coil 3 for accommodating the hall element; the hall element is used for monitoring magnetic field data in the gap in real time.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
