Description

Winding device for superconducting coil assembly and control method thereof {COIL WINDING APPARATUS FOR SUPERCONDUCTING COIL ASSEMBLY AND CONTROL METHOD THEREOF}

The present invention relates to a winding device for a superconducting coil assembly and a control method thereof. More specifically, the present invention relates to a winding device for a superconducting coil assembly and a control method thereof. More specifically, the present invention relates to cracking due to the bending radius by adjusting the separation distance between the bobbin and the superconducting wire wound on the superconducting wire cassette as the winding of the superconducting wire progresses. It relates to a winding device for a superconducting coil assembly and a method of controlling the same for preventing generation of superconducting coils and manufacturing small or large capacity superconducting coil assemblies.

A superconductor is a device whose electrical resistance becomes zero at extremely low temperatures. Because it offers the advantages of high magnetic field, low loss, and miniaturization compared to existing copper (cu), it is already being used in various application fields.

A superconducting coil is a coil made using a superconductor. These superconducting coils are used in MRI, NMR, particle accelerators, magnetic separation devices, etc. to improve efficiency and performance. In addition, its application technologies, such as power cables, superconducting transformers, and superconducting motors, are continuously being researched throughout the industry.

In recent years, superconducting application devices using superconductors are gradually increasing in capacity. In that case, superconducting coils used in superconducting applications also become subject to high magnetic fields and large currents. At this time, the number of superconducting coils increases, and the size of one superconducting coil increases.

It is important that the superconducting coil acts on the superconducting wire with appropriate tension so that the superconducting wire does not float between turns and is wound without twisting. This is because it is necessary for mechanical safety and thermal stabilization when superconducting coils are applied to superconducting applications.

However, in most cases, superconducting coils are wound by a vertical winding machine. In other words, the vertical winding machine winds the superconducting coil while forming the bottom surface and the cassette tape around which the superconducting wire is wound at 90°.

Therefore, when winding a large capacity superconducting coil using a vertical winding machine, the axis of the winding machine must support the weight of the bobbin, the weight of the superconducting wire, and in special cases, the weight of the iron core inside the superconducting coil.

Moreover, in this case, assuming that the weight of the superconducting coil makes it difficult for the superconducting wire to be wound in a repetitive position and is twisted, when such a superconducting coil is applied to a superconducting application device, it is necessary to satisfy the electrical output consistent with the design value. Not only is it difficult, but the superconducting coil may be damaged due to Lorentz force within the superconducting coil.

Therefore, for superconducting coils to be applied to high-capacity superconducting applications, it is necessary to provide a winding method that adapts to the trend of increasing capacity and reduces winding time.

Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings.

1 to 3 are diagrams showing a winding device for a superconducting coil assembly according to an embodiment of the present invention.

As shown in FIGS. 1 to 3, the winding device 100 for a superconducting coil assembly according to an embodiment of the present invention is a winding device for a racetrack-type field coil used in a large-capacity superconducting motor, and has a winding device for a racetrack-type field coil used in a large-capacity superconducting motor. A superconducting wire is wound horizontally on a racetrack-type bobbin (10) with a long straight portion. Here, the bobbin 10 has a racetrack shape and a superconducting wire is wound around it to form a superconductive coil assembly.

This superconducting coil assembly can be applied to power devices such as a superconducting magnet, superconducting cable, superconducting motor, or superconducting generator.

Additionally, the superconducting coil assembly may be configured as a pancake coil assembly having at least one or more layers depending on the superconducting application device. For example, a superconducting coil assembly can be a Single Pancake Coil (SPC) consisting of one layer, a Double Pancake Coil (DPC) consisting of two layers, and a Multi Pancake Coil (MPC) consisting of four or more even layers. there is. If it consists of four layers, it may be QPC (Quadruple Pancake Coil). Ultimately, when it is composed of multiple layers, it is composed of multiple layers of 2.

Meanwhile, the winding device 100 adjusts the separation distance between the bobbin 10 and the superconducting wire wound around the superconducting wire cassette 110 as the winding of the superconducting wire progresses, thereby preventing cracks from occurring due to the bending radius, and preventing cracks from occurring due to the bending radius. Large-capacity superconducting coil assemblies can be manufactured.

That is, the winding device 100 includes a superconducting wire cassette 110 for supplying a superconducting wire, a rotating plate 120 that rotates to wind the superconducting wire supplied from the superconducting wire cassette 110 to the bobbin 10, and a superconducting wire cassette 110. The wire cassette 110 is mounted and coupled to the rotating plate 120 in a fixed state, and includes an arm frame 130 capable of adjusting the separation distance between the bobbin 10 and the superconducting wire wound around the superconducting wire cassette 110. do.

Specifically, the superconducting wire cassette 110 is rotatably installed on the cassette rotation axis of the cassette mounting unit 140, which will be described later, parallel to the ground, and the superconducting wire wound around the outer peripheral surface of the wheel shape is pulled and rotated to form the superconducting wire. is released.

Here, the superconducting wire refers to a material whose electrical resistance is 0. For example, it may be a BSCCO (Bi _x Sr _x Ca _x Cu _x O _x )-based conductor wire. These superconducting wires are called low-temperature superconductors (LTS), which are materials that have a current resistance close to 0 at 4K, the temperature of liquid helium, and high-temperature superconductors (LTS), which are materials that show superconductivity at 77K, the temperature of liquid nitrogen, which is higher than liquid helium. It may include wire (High Temperature Superconductor, HTS).

Next, the rotation plate 120 is a work table formed in a racetrack shape corresponding to the shape of the bobbin 10 parallel to the ground, with the bobbin 10 disposed on the upper surface and the plate rotation axis 121 on the lower surface. They are integrally connected in this vertical direction.

Here, the bobbin 10 can be fixed to the upper surface of the rotation plate 120 when winding the superconducting wire, and the plate rotation shaft 121 is rotatably fastened to the rotation driver 150, which will be described later.

In addition, the shape of the rotating plate 120 can be implemented as a race track type as shown in FIG. 1, but is not limited to this and can be implemented in various shapes.

Next, the arm frame 130 implements a horizontal winding environment so that the bobbin 10 and the superconducting wire cassette 110 are spaced apart on the same virtual plane parallel to the ground, and has an arm facing a predetermined direction. By adjusting the length, the separation distance between the bobbin 10 and the superconducting wire wound around the superconducting wire cassette 110 can be adjusted.

Referring to Figures 1 and 2, the arm frame 130 is composed of a first arm facing a first direction and a second arm facing a second direction, and the deployment length of the first and second arms can be adjusted step by step. It may be in any form.

In particular, the separation distance between the bobbin 10 and the superconducting wire wound around the superconducting wire cassette 110 is adjusted based on the minimum bending radius of the superconducting wire.

Specifically, cracks may occur in the superconducting wire material if the bent portion is smaller than the minimum bending radius.

However, since the separation distance between the superconducting wires wound around each of the bobbin 10 and the superconducting wire cassette 110 becomes closer by the thickness of the superconducting wire wound around the bobbin 10, the bending radius at the point where the superconducting wire is bent is at a minimum. It can be smaller than the bending radius.

Therefore, the arm frame 130 increases the separation distance between the bobbin 10 and the superconducting wire wound around the superconducting wire cassette 110 by adjusting the length so that the bending radius at the point where the superconducting wire is bent is larger than the minimum bending radius. give.

This prevents the occurrence of cracks due to the bending radius as the superconducting wire is wound for a small-capacity or large-capacity superconducting coil assembly, and provides a winding environment in which the superconducting wire can be wound.

Referring to FIG. 3, the winding device 100 includes a distance measuring sensor 210 for measuring the separation distance between the bobbin 10 and the superconducting wire wound around the superconducting wire cassette 110, and the distance measured by the distance measuring sensor. A control unit 220 for controlling the length adjustment of the arm by comparing the critical distance between superconducting wires converted based on the distance and the minimum bending radius, and an arm driving unit 230 for driving the arm step by step according to the control signal from the control unit. Includes.

Here, the control unit 220 includes at least one processor and a memory for storing computer-readable instructions.

This control unit 220 performs a control method of a winding device for a superconducting coil assembly according to an embodiment of the present invention when computer-readable instructions stored in the memory are executed by at least one processor.

Here, the processor is at least one processor and may also be called a controller, microcontroller, microprocessor, microcomputer, etc. Additionally, the processor may be implemented by hardware, firmware, software, or a combination thereof.

Additionally, memory may be a single storage device, or may be a collective term for multiple storage elements. Computer-readable instructions stored in memory may be executable program codes, parameters, data, etc. Additionally, the memory may include Random Access Memory (RAM), or Non-Volatile Memory (NVRAM) such as magnetic disk storage or flash memory.

Referring to Figures 4 and 5, when manufacturing a small capacity superconducting coil assembly as shown in Figure 4, the separation distance between the bobbin 10 and the superconducting wire cassette 110 is adjusted to be short, and the large capacity superconducting coil assembly is manufactured as shown in Figure 5. When manufacturing, the separation distance between the bobbin 10 and the superconducting wire cassette 110 is adjusted to be short.

In addition, when manufacturing a large-capacity superconducting coil assembly, the separation distance between the bobbin 10 and the superconducting wire cassette 110 may be increased as shown in FIGS. 4 to 5 while winding the superconducting wire.

Figures 4 and 5 are diagrams explaining the adjustment of the separation distance according to the size of the superconducting coil assembly.

In addition, the arm frame 130 may be coaxially coupled to the plate rotation axis 121 of the rotation plate 120 passing through the center. At this time, when the arm frame 130 is coupled with the plate rotation axis 121, it has a built-in bearing (not shown) that contacts the outer peripheral surface of the plate rotation axis 121, so that it can maintain a fixed state with respect to the rotation of the plate rotation axis 121. there is.

The arm frame 130 forms a plate-shaped arm plate 131 to install the cassette mounting portion 140, which will be described later, at both ends of the first and second arms. The superconducting wire cassette 110 is rotatably mounted on the cassette mounting unit 140.

In this case, the first and second arms may be integrated or independent frames forming a symmetrical structure with a mutually unfolding angle of 180°. Here, if the first and second arms are independent frames, they can be designed to rotate around the plate rotation axis 121 to implement various deployment angles.

Furthermore, the arm frame 130 may be composed of at least one arm. 1 and 2 show a case where the arm frame 130 is composed of first and second arms, that is, two arms, as described above.

Additionally, assuming that the arm frame 130 is composed of three arms, a structure in which each arm has a deployment angle of 120° can be formed. This means that when manufacturing a pancake coil assembly with a three-layer structure, each layer can be wound simultaneously.

Meanwhile, the winding device 100 further includes a cassette mounting unit 140, a rotation driving unit 150, a support frame 160, and a tension adjusting unit 170.

First, the cassette mounting unit 140 is installed on the arm plate 131 formed at the end of the arm frame 130 to mount the superconducting wire cassette 110.

In addition, the cassette mounting unit 140 is provided with a cassette rotation axis whose height can be adjusted up and down, and the center of the superconducting wire cassette 110 is fastened to the cassette rotation axis when the superconducting wire cassette 110 is mounted.

This cassette mounting unit 140 releases the superconducting wire cassette 110 when the superconducting wire is wound around the bobbin 10 by rotation of the rotating plate 120.

In addition, the cassette mounting unit 140 can simultaneously wind the superconducting wire by adjusting the position (height) of the superconducting wire cassette 110 differently depending on each layer constituting the DPC or MPC.

Referring to FIG. 6, when configuring a DPC, the first cassette mounting portion installed on the first arm is a first superconducting wire cassette 110a with a height h1 corresponding to the first layer 11 of the bobbin 10. Adjusts the position of , and the second cassette mounting unit installed on the second arm adjusts the position of the second superconducting wire cassette 110b to the height h2 corresponding to the second layer 12 of the bobbin 10. Thereafter, the superconducting wire is simultaneously wound on the first layer 11 and the second layer 12 of the bobbin 10 by rotation of the rotating plate 120.

Figure 6 is a diagram explaining the superconducting wire winding that constitutes a double pancake coil (DPC).

In addition, the cassette mounting unit 140 adjusts the position (height) of the superconducting wire cassette 110 equally for one layer constituting the SPC to attach an insulating tape (e.g., Kapton tape or SUS tape, etc.) on the superconducting wire. It can be wound.

Referring to FIGS. 7 and 8, when configuring an SPC, the first cassette mounting unit installed on the first arm adjusts the position of the superconducting wire cassette 110 to the height h1 corresponding to the bobbin 10, The second cassette mounting unit installed on the second arm adjusts the position of the insulating tape cassette 110b to the corresponding height h1 of the bobbin 10.

At this time, the insulating tape starts winding after the winding start time of the superconducting wire with a difference in the winding start time of the superconducting wire, but the starting point (SP) of the superconducting wire is changed by the rotation of the rotating plate 120 when viewed from the insulating tape cassette side. When located within the visible area with a predetermined angle (θ), it is desirable to start winding on the superconducting wire from the starting point (SP) of the superconducting wire.

Through this, the insulating tape is wound together between turns of the superconducting wire to form a spiral type winding structure of the superconducting wire and the insulating tape. In other words, looking at the cross section of this spiral winding structure, superconducting wire - insulating tape -... -Superconducting wire-Insulating tape, like superconducting wire and insulating tape, is alternately laminated.

Figures 7 and 8 are diagrams explaining the superconducting wire and insulating tape windings that make up the SPC (Single Pancake Coil).

Next, the rotation driver 150 rotates the plate rotation shaft 121 formed integrally with the lower surface of the rotation plate 120. This rotation drive unit 150 includes a motor and a motor driver, and is connected to the plate rotation shaft 121 through a gear and chain connection. As shown in FIG. 2, the rotation drive unit 150 may be composed of a plurality of units depending on the required rotational force.

In this way, the rotation driver 150 controls the rotation of the rotation plate 120. Rotation of the rotating plate 120 releases the superconducting wire wound around the superconducting wire cassette 110, allowing the superconducting wire to be continuously wound around the bobbin 10.

Next, the support frame 160 forms a frame that supports the rotation plate 120 and the arm frame 130 at a constant height from the ground, and a connection structure between the plate rotation axis 121 and the rotation drive unit 150 can be installed. Construct a frame.

Next, the tension adjusting unit 170 is installed on the arm plate 131, and when the superconducting wire is wound from the superconducting wire cassette 110 to the bobbin 10 by the rotation of the rotating plate 120, the tension adjusting unit 170 is installed on the arm plate 131. By adjusting the intensity of tension, it protects the superconducting wire and minimizes the electrical and mechanical effects of the winding of the superconducting wire.

Here, the tension control unit 170 may initially couple the superconducting wire to the bobbin 10 and then adjust the tension based on the measured tension intensity. Here, a coupling groove (not shown) is formed in the bobbin 10 to allow the superconducting wire to be initially coupled, and one end where the winding of the superconducting wire begins is fixed by being caught in the coupling groove of the bobbin 10.

This tension control unit 170 includes a guide roller 171, which forms the movement path of the superconducting wire, and a tension drive unit 172 that rotates at least one of the guide rollers 171 to apply the tension of the superconducting wire at a constant intensity. Includes.

Additionally, a material (eg, rubber, epoxy, etc.) that can apply force in close contact with the superconducting wire may be applied to the guide roller 171 connected to the tension driving unit 172.

In addition, although not shown in the drawing, the tension adjusting unit 170 may further include a tension measuring sensor for measuring the intensity of tension acting on the superconducting wire and a winding length measuring sensor for measuring the winding length of the superconducting wire. .

Figure 9 is a diagram of a control method of a winding device for a superconducting coil assembly according to an embodiment of the present invention.

The control unit 220 checks the separation distance between the bobbin 10 and the superconducting wire wound around the superconducting wire cassette 110 measured through the distance measuring sensor 210 (S301).

Thereafter, the control unit 220 compares the separation distance measured by the distance measurement sensor 210 and the critical distance between the superconducting wires converted based on the minimum bending radius (S302). At this time, when it is confirmed that the separation distance is smaller than the critical distance (S302), the control unit 220 generates a control signal for adjusting the length of the arm (S303).

Afterwards, the control unit 220 transmits a control signal to the arm driving unit 230 to control the arm driving unit 230 to drive the arm step by step (S304).
