Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alternating current superconducting coil device, and more particularly to a large capacity multi-layer winding alternating current superconducting coil device.

[0002]

2. Description of the Related Art Conventionally, in a superconducting coil device for alternating current, a superconducting wire is wound with a certain tension on the outer peripheral surface of a cylindrical winding frame made of a non-metallic material for electrical insulation. A superconducting wire for one layer wound around a cylindrical winding frame is called a coil element. A superconducting coil device is manufactured by repeating the operation of stacking the winding layer of the next layer on the coil element of the previous layer and winding the superconducting wire around the winding element so that this coil element is formed by the required number of layers. .

Each coil element is fixed so as to be pressed against the coil element in the previous layer on which the cylindrical winding frame of the layer is laminated, by the winding tension of the superconducting wire itself forming the coil element. There is also a method of fixing each coil element by adhering each other with an adhesive.

As a conventional example using a coil element, there is an example described in JP-A-63-292604. In this example, a refrigerant passage groove is provided on the outer peripheral surface, a spiral groove is further provided on the surface thereof, and a superconducting coil device in which coil elements formed by winding a superconducting wire while accommodating in the spiral groove are overlapped is provided. Disclosure.

[0005]

However, in such a conventional superconducting coil device, when the winding tension of the superconducting wire is not large, the coil elements cannot be fixed sufficiently and the coil of the superconducting coil device is not sufficiently fixed. The rigidity of the part cannot be increased. Therefore, the electromagnetic force acting on the superconducting wire by the magnetic field and current generated by the superconducting coil device itself causes the problem that the superconducting wire vibrates during AC energization to reduce the quench current value (normal conduction transition current value). is there.

Here, the quench means that the superconducting wire and the winding frame around which it is wound rub against each other, the temperature of the superconducting wire rises due to frictional heat, and the critical temperature (the temperature at which the superconducting state is broken) is reached.
This is a phenomenon in which the entire coil changes to the normal conducting state.

In particular, as the size of the superconducting coil device increases and the current value of the coil current to be applied increases, the electromagnetic force acting on the superconducting wire due to the magnetic field generated by the superconducting coil device also increases. In addition, when an alternating current is applied, an electromagnetic force acts on the superconducting wire at a frequency twice the frequency of the alternating current. Therefore, quenching is more likely to occur in a large superconducting coil.

On the other hand, if the superconducting wire is wound with a large tension in order to sufficiently fix the coil elements, the superconducting wire may be mechanically damaged or the filament in it may be damaged depending on the kind of the superconducting wire. The characteristics of the superconducting wire may be deteriorated due to disconnection, which is one of the factors that deteriorate the characteristics of the superconducting coil device.

Further, in order to bring the superconducting wire into the superconducting state, the superconducting coil device needs to use a cooling medium such as liquid helium to attain an extremely low temperature of at least about -270.degree. In such an extremely low temperature range, the durability of ordinary adhesives is limited.

For this reason, in a large-sized superconducting coil device in which the electromagnetic force acting on the superconducting wire is large and the frequency thereof is also high, the coil elements are fixed with only an adhesive and used to maintain the required rigidity. Adhesives that can be applied are very limited, and the application method of the adhesive must be carefully considered. Therefore, it takes a lot of time and effort to manufacture such a superconducting coil device.

There is also a method in which the entire outermost layer of the superconducting coil device is hardened with resin, or a fastening member for fastening the entire superconducting coil device from the outermost layer is used. But,
The electromagnetic force acting on the superconducting wire has the strongest effect on the superconducting wire wound in the innermost layer, and it is actually suppressed by stopping it from the outermost layer. Have difficulty.

Further, in the superconducting coil device, since the bobbin is a non-metallic material and the superconducting wire is a metallic material,
When the superconducting coil device is immersed in a cryogenic refrigerant such as liquid helium to put the superconducting coil device in the superconducting state, rattling occurs between the superconducting wire and the bobbin due to the difference in heat shrinkage between the bobbin and the superconducting wire. , The rigidity of the coil part was lost.

In view of the above problems, the object of the present invention is to
It is an object of the present invention to provide a superconducting coil device capable of sufficiently fixing coil elements in order to effectively prevent the occurrence of quenching when an alternating current is applied.

[0014]

Next, an example of the manufacturing method of this embodiment will be described with reference to FIGS. 3, 4 and 5.

First, the superconducting wire 10 is made of an insulator, for example,

At this time, as shown in FIG. 3, the diameter of the superconducting wire 10 and the depth and shape of the winding groove 5 are measured from the outer peripheral surface of the first-layer cylindrical winding frame 1 to the superconducting wire 10.
Shall not extend outside.

When the winding work of the first layer is completed, as shown in FIG. 4, the two reel members 2a and 2b made of the same GFRP as the first-layer cylindrical reel 1 are attached to the first layer. It is applied to the outer peripheral surface of the cylindrical winding frame 1 and temporarily fixed. To temporarily fix,
For example, the joint band 13 is mounted on the outer peripheral surface of the winding frame members 2a and 2b where the cutout portion 3 and the winding groove portion 5 are not provided.

Further, the tightening screw 1 for the joint band 13
By tightening 3a, the reel members 2a and 2b are firmly fixed to the first layer cylindrical reel 1. Note that FIG. 4 shows a state in which the joint bands 13 are wound around both ends of the winding frame members 2a and 2b in the coil axis direction.

As described above, by using the same material for the cylindrical bobbin 2 which is the bobbin of the coil element and the fixing member 4, even if the superconducting coil device is cooled to a cryogenic temperature to bring it into a superconducting state, Since the cylindrical winding frame 2 and the fixing member 4 have substantially the same thermal contraction rate, the fixed state can be maintained and rattling between the coil elements can be prevented.

During the winding operation, the superconducting wire 10 is wound around the temporarily fixed winding frame members 2a, 2b with a predetermined tension, and the fixing member 4 is applied to the superconducting wire 10 at a tension higher than the tension.
