Description

  The present invention relates to a superconducting coil module and a rotating device.

Since the superconducting wire forming the superconducting coil is in a superconducting state at a very low temperature, it is modularized by a heat insulating container that houses the superconducting coil together with a liquid refrigerant for cooling the superconducting coil to a very low temperature.
For example, Patent Document 1 discloses a superconducting coil that includes a racetrack-type superconducting coil, a racetrack-type inner tank that stores the superconducting coil and liquid refrigerant, and an outer tank that stores and insulates the inner tank. A coil module is described.
This superconducting coil module supports any position of the inner tank with a support body having rigidity in three axial directions inside the outer tank, and rigidly supports both end portions, outer periphery and inner periphery of the inner tank in one axial direction. The generation of vibration applied to the superconducting coil is suppressed by supporting the substrate with the support.

Japanese Patent Laid-Open No. 06-140239

  However, in the superconducting coil module described in Patent Document 1, since both ends of the support are fixed to the inner tank or the outer tank, the superconducting coil is shifted to a cooled state or an uncooled state. The support member was easily subjected to thermal stress. For this reason, it is necessary to take measures such as increasing the number of support members or increasing the size of the support members in order to cope with the thermal stress, thereby increasing intrusion heat and possibly causing quenching in the superconducting coil. There were some problems.

  In the superconducting coil module, the inner tank is formed in a racetrack shape following the superconducting coil, but the outer tank is formed in a box shape. For this reason, there was a problem that the iron core could not be disposed inside the superconducting coil, and the magnetic flux of the superconducting coil could not be increased.

  An object of the present invention is to reduce heat penetration of a superconducting coil module.

And a plurality of support portions for supporting the coil unit by support members that are fixed and not fixed.

Furthermore, the invention of claim 1

Furthermore, the invention of claim 1
Wherein the plurality of support portions, seen including a second supporting portion for supporting said coil unit from the three or more directions by three or more of the support member,

The first support portion holds the coil unit from two directions around the longitudinal direction without holding the coil unit in the longitudinal direction.
The second support portion is characterized in that the coil unit is not held in the longitudinal direction but is held from four directions around the longitudinal direction .

The invention according to claim 2 is the superconducting coil module according to claim 1 ,
The superconducting coil, the cooling module, and the outer tub each have two parallel linear portions,
The support member of the first support portion provided in one of the linear shape portions and the support member of the first support portion provided in the other linear shape portion are both in the same two directions. The coil unit is supported.

The invention described in claim 3 is the superconducting coil module according to claim 1 ,
The two directions in which the first support portion supports the coil unit are directions corresponding to directions of electromagnetic force received by the superconducting coil from an external magnetic field.

According to a fourth aspect of the present invention, in the rotating device,

The rotor has an iron core disposed inside the annular shape of the outer tub of the plurality of superconducting coil modules,
And an armature provided to face the outer periphery of the rotor.

In the present invention, between the outer tub and the coil unit, only one end is fixed to the inner wall of the outer tub or the outside of the coil unit, and the other end extends to the outside of the coil unit or the inner wall of the outer tub. Since the coil unit is supported by a support member that is not fixed, each support member allows the longitudinal behavior of the superconducting coil even when thermal contraction or thermal expansion occurs due to a large temperature change of the superconducting coil. It is possible to appropriately hold the position inside the outer tub from the periphery of the coil unit without increasing the number or increasing the size of the support member.
Therefore, it is possible to reduce intrusion heat and effectively suppress quenching of the superconducting coil.

  Further, when the coil unit is supported using the first support part that supports the coil unit from two directions, the support member can be reduced, thereby further effectively reducing heat penetration. It becomes possible.

As shown in FIG. 3A, the second support portion 50 supports the inner tub 30 located at the center of the outer tub 40 from the four directions of upper, lower, left and right by the support members 51-54.
As shown in FIG. 3B, each of the support members 51 to 54 has a cylindrical shape with a through hole formed in the center, and only one end portion in the center line direction is fixed to the inner wall of the outer tub 40, The other end portion is extended to the outer wall side of the inner tank 30 but is not fixed. When the superconducting coil 20 is not subjected to an external force, the other end portion is a free end in a state where a slight clearance occurs. In addition, each support member 51-54 is formed from the material excellent in rigidity and heat insulation, for example, FRP.
That is, the support members 51 to 54 hold the position from the top, bottom, left, and right so that the inner tank 30 does not greatly move and change, while the long sides 31 and 33 and the short sides 32 and 34 of the inner tank 30 The longitudinal direction is not held, and the position variation is allowed.

In the generator 100, during power generation, the superconducting coil 20 is energized, and the inner yoke 110 is rotated counterclockwise in FIG. 5 by, for example, torque using wind power while causing the superconducting coil 20 to function as an electromagnet. That is, the symbol W indicates the rotation direction in which the inner yoke 110 rotates during power generation. Further, the armature 120 of the generator 100 is assumed to be three-phase synchronized.
As for the energizing direction of the superconducting coil 20 during power generation, a current flows in a direction in which one long side portion 21 is directed toward this side perpendicular to the paper surface of FIG. 5, and the other long side portion 22 is the paper surface of FIG.

On the other hand, on the inner peripheral surface of the armature 120 facing the inner yoke 110, a plurality of coils 121 having tips at the inner yoke 110 side are provided at uniform intervals, and the generated current is extracted from each coil 121. .
In the above arrangement, when the iron core 111 is disposed inside the superconducting coil 20, a magnetic field indicated by a solid arrow in FIG. 5 is formed between the inner yoke 110 and the armature 120 during power generation. Due to the rotation of the inner yoke 110, the magnetic flux density on the upstream side in the rotational direction is somewhat increased.

The thick arrows A1 and A2 in FIG. 5 indicate the directions of electromagnetic force based on the armature reaction that the long side portion 21 and the long side portion 22 of the superconducting coil 20 respectively receive.
The electromagnetic force A1 based on the armature reaction of the long side portion 21 of the superconducting coil 20 and the armature reaction of the long side portion 22 depending on various conditions such as the energization direction of the superconducting coil 20, the rotation direction of the inner yoke 110, and the magnetic field formation direction. Is generated in the same direction (downward in FIG. 5).

An arrow B1 and an arrow B2 in FIG. 5 indicate the directions of Lorentz forces received by the long side portion 21 and the long side portion 22 of the superconducting coil 20, respectively.
The Lorentz force is due to the direction of the magnetic field and the direction of current flow, according to Fleming's left-hand rule. In this case, a current flows in the opposite direction to the long side portion 21 and the long side portion 22 of the superconducting coil 20, but the direction of the magnetic field is also reversed due to the arrangement of the long side portion 21 and the long side portion 22, respectively. The directions in which the Lorentz forces B1 and B2 are generated are the same, and are the lower side in FIG.

  As described above, the current flows in the opposite direction to one of the long side portion 21 and the other long side portion 22 of the superconducting coil 20, but the directions of the electromagnetic forces generated in them are the same. Accordingly, the first support portions 60 provided on the one long side portion 41 and the other long side portion 43 of the outer tub 40 have the same arrangement of the two support members 61 and 62 with respect to the inner tub 30. be able to.

[Technical effects of the embodiment of the invention]
In the superconducting coil module 10, the support members 51 to 54, 61, 62 of the first support part 60 and the second support part 50 are all fixed to the inner wall of the outer tub 40, and the other end part is Since it extends to the outside of the coil unit 2, that is, the outer wall side of the inner tank 30, when the liquid refrigerant is supplied to the inner side of the inner tank 30 of the superconducting coil module 10, or when the liquid refrigerant is removed. Even when the superconducting coil 20 and the inner tank 30 expand or contract in the longitudinal direction due to a sudden temperature effect or a temperature rise, the behavior of the superconducting coil 20 and the inner tank 30 in the longitudinal direction. Therefore, it is possible to effectively avoid the breakage of the support members 51 to 54, 61, and 62.

The second support part 50 supports the inner tank 30 from four directions by the support members 51 to 54, and the first support part 60 supports the inner tank 30 from two directions by the support members 61 and 62. From the above, even when the superconducting coil module 10 is attached to the generator 100 and performs a rotational motion or performs an unscheduled motion at the time of transportation work, the inner tank 30 is held from the surrounding four sides by the second support portion 50, The prescribed arrangement can be maintained.
Furthermore, even when the superconducting coil module 10 is mounted on the generator 100 and performs power generation, not only the second support portion 50 but also the first support portion 60 causes various external forces that the superconducting coil 20 receives from the magnetic field. Since it is supported from the corresponding direction, the inner tank 30 can be held at an appropriate position.
Further, by supporting the inner tub 30 also using the first support portion 60, the inner tub 30 can be supported with fewer support members than before, and heat conduction is reduced and the superconducting coil 20 is kept at a very low temperature. Can be maintained in a state.
In addition, the second support member 50 supports the inner tank from four directions, but during power generation, only two of the four support members are attached to the inner tank 30 by various external forces that the superconducting coil 20 receives from the magnetic field. In this case, the heat conduction can be reduced and the superconducting coil 20 can be maintained in a cryogenic state.

Moreover, the 1st support part 60 provided in one of the two long side parts 41 and 43 of the outer tank 40, and the 1st support part 60 provided in the other are both the inner tank 30 from the same two directions. I support it. These first support portions 60, 60 can both support the inner tank 30 from the appropriate direction within the long side portions 41, 43, and avoid an unexpected displacement of the inner tank 30. It becomes possible.
Moreover, the 1st support part 60 provided in one of the two long side parts 41 and 43 of the outer tank 40, and the 1st support part 60 provided in the other are both the inner tank 30 from the same two directions. I support it. Since these first support portions 60 and 60 both correspond to the direction of the electromagnetic force that the superconducting coil 20 receives from an external magnetic field, it is possible to avoid an unexpected displacement of the inner tank 30 due to the electromagnetic force. It becomes possible.

  In addition, since the outer tub 40 is annular, the iron core 111 can be disposed inside the annular shape of the superconducting coil 20, and the magnetic force of the superconducting coil 20 can be enhanced.

[Comparative example]
The superconducting coil 20 (long side 1.5 m, short side 0.5 m) and an inner tank 30 for storing the liquid refrigerant and an outer tank 40 for storing the inner tank 30 are provided. Between the inner walls, support members made of FRP cylinders are installed in the same arrangement as that of the second support part 50 at eight locations shown in FIG. At this time, one end of each support member was fixed to the inner wall of the outer tub 40 and the other end was fixed to the outer wall of the inner tub 30 with an adhesive.
Further, the internal space of the outer tank 40 was evacuated by a rotary pump and a turbo molecular motor, and then liquid nitrogen and liquid helium were passed through the inner tank 30 to cool the superconducting coil 20.
After confirming that the superconducting coil 20 was sufficiently cooled, the liquid refrigerant was stopped from flowing into the inner tank 30, and the superconducting coil 20 was returned to room temperature.
Then, when each support member was confirmed, damage to the support member was seen in the part which adhered the support member. It seems that the support member could not withstand the thermal stress during cooling of the superconducting coil 20.

It is desirable to mix and use the smallest number of individuals that can be supported.

Moreover, in the said embodiment, although the generator 100 was illustrated as a rotation apparatus, the superconducting coil module 10 mentioned above is applicable also to a motor.
Further, when the superconducting coil module 10 can achieve its purpose with its magnetic force without arranging the iron core inside, the iron core 111 need not be used. Moreover, in that case, it is good also as a rectangular parallelepiped housing | casing, without forming the large opening part of the planar view center part in the outer tank 40. FIG.
