Here, it is preferable that the rail 120 has a concave-convex shape in cross section.

The supporting means 200 is the coil 500 is placed for the lapping operation, it is composed of a support portion 210, the cylinder 220 and the support plate 230.

As shown in FIG. 3, the support part 210 is made of steel having a 'c' shape in order to install the support means 200 on the plate 100 so that both ends thereof are fixed to the plate 100. A cylinder 220 is installed perpendicular to the plate 100 at an inner center of the support 210, and a rod end reciprocating through the cylinder 220 penetrates a hole formed in the support 210. Thus, the load moves up and down, that is, up and down.

The cylinder 220 may be generally used hydraulic or pneumatic method, the support plate 230 is fixed to the end of the rod up and down by reciprocating motion. The support plate 230 is also made of steel, and the coil 500 is placed there.

In addition, the rod of the cylinder 220 is provided with holes on both sides of the through hole formed in the support portion 210, the guide rod 240 penetrating between the holes are fixed to the support plate 230.

By constituting the guide rod 240 it is possible to ensure a more stable support when the support means 200 supports the coil 500.

The supporting means 200 configured as described above is disposed 16 along the circumference of the plate 100 in the shape of the coil 500 and is used for the nuclear fusion device Tokamak. According to the 'D' shape TF (Toroidal Field: Toroidal Coil) magnet structure, or circular PF (Poloidal Field: Pooidal Coil) magnet structure correspondingly arranged and installed.

When the coil 500 for forming the magnet structure is placed on the support means 200, the coil 500 is controlled by the controller 300 and the coil 500 coupled thereto when the cylinder 220 is operated. The supporting plate 230 is supporting the entire coil 500 will be lifted.

Referring to FIG. 5, the lapping means 400 is provided at one side of a central shaft pillar formed at a central portion of the plate 100, and rotates about the frame 410), and the middle of the frame 410. Is installed in the portion is connected to the other means of the transfer means 430 and the frame 410 to move the lapping means 400 along the rail 120 installed on the plate 100 to wrap the coil 500 The wrapping unit 420 is configured. The transfer means 430 and the wrapping unit 420 are operated under the control of the controller 300.

One side of the frame 410 of the horizontally installed length member is coupled by a fastening means (bearing, etc.) capable of rotating about a central column shaft installed in the plate 100, the other side is approximately the support means 200 The other side portion of the frame 410 is to pass to the upper side of the support means 200 disposed in a circular shape to be located on the upper side of the).

The transfer means 430 moves the frame 410 and moves along the rail 120 provided in the plate 100. The transfer means 430 is connected to the central portion of the frame 410 and moves along the rail 120 under the control of the controller 300.

Thus, when the conveying means 430 moves along the rail 120, the frame 410 moves around the center column shaft 110.

The wrapping part 420 is installed on the other side of the frame 410 connected to the central pillar 110, and wraps the coil 500 passing through the through hole formed in the wrapping part 420.

Here, the wrapping unit 420 is largely connected to the frame 420 and the sliding guide 421, the bracket 422 fixed to the guide 421 and coupled to the driving means (motor) Rotating disk 423 is rotated by receiving the power of the coil 500 and the tape roll to be wrapped on the coil 500 is configured to include a roll.

The guide 421 is connected to the frame 420 and is provided to be freely slidably moved a predetermined distance along the longitudinal direction of the frame 420. This is not necessary in the case of the circular-shaped porodal coil PF, but in the case of the D'-shaped toroidal coil, the guide 421 has to be moved in correspondence with the shape because the wrapping portion 420 has to be moved in correspondence with the shape. ) To be able to move.

In order to couple the guide 421 to the frame 420 to be movable, the guide 421 may be freely moved using a sliding member, and a method of moving by receiving power from a driving means may be proposed.

As shown in FIG. 6, the bracket 422 and the rotation disc 423 have a through hole through which the coil 500 can be penetrated to the center, and the coil 500 penetrates.

The through hole formed in the bracket 422 is provided with a through hole by a structure that is fastened to the coupling member in a separated state, as shown in FIG. 7, because the coil 500 formed by winding the inner conductor conductor (CICC) is any Since one part has a closed structure rather than an open structure, since one side of the coil 500 must penetrate in order to perform the lapping operation, the half is divided into half around the through-hole of the bracket 422 and the coupling member Although suggesting an assembly method using, as well as this can also propose a structure that can be fastened by hinged to open only one side.

The rotating disk 423 is mounted to one surface of the bracket 422 formed as described above. The rotating disk 423 is also provided with a through hole through which the coil 500 can pass. Like the bracket 422 has a structure in which a through hole is provided by a fastening method.

Here, the coil 500 is installed in close contact with each other by a pair of rollers 425 made of two by the elastic member so as to be wound in a state where the tension is secured when the tape is wound on the coil 500, and passes through the tape between the rollers 425. Is delivered to the coil 500.

In addition, the reason for having three tape rolls 424 is to use as an auxiliary for a quick lapping operation when the tape wound up in one tape roll 424, or tapes of different types depending on the purpose It may be wound up.

Next, the installation and operation of the ground lapping apparatus of the coil formed of the superconducting twisted pair conductor according to the present invention will be described in detail.

When the installation of the wrapping unit 420 is completed, the wrapping unit 420 is operated by the control unit 450 provided in the conveying means 430, and at the same time operates the conveying means 430. When the wrapping unit 420 is operated, the tape wound on the tape roll 424 starts to be wound on the coil 500 while the rotating disc 423 rotates.

At this time, the transfer means 430 is gradually moved through the rail 120 is wrapped while the tape overlaps the coil 500 at a predetermined interval.

When the wrapping part 420 passes through the supporting means 200 supporting the coil 500 while wrapping the coil 500, the supporting plate 230 which is up (UP) by the cylinder 220 is down ( DOWN) while passing the lapping unit 420, and when it passes, the supporting plate 230 is up (UP) to support the coil 500.
