Description

Superconducting Persistent Current Switch and Winding Apparatus therefor

The present invention relates to a superconducting permanent current switch and a bobbin and winding device therefor, and more particularly to a superconducting magnet such as a magnetic resonance tomography (MRI) device, a nuclear magnetic resonance (NMR) device, and a superconducting energy storage (SMES) system. The superconducting permanent current switch, which is applied to the system and converts the superconducting magnet system from the normal state of charge to the superconducting permanent current operating state, and the superconducting wire for the superconducting permanent current switch, which is improved, are easily used by the induction winding method. It relates to a bobbin and a winding device capable of winding.

In general, the superconducting permanent current operation uses a feature that allows a high current to be continuously supplied to a superconducting state in which the electrical resistance becomes zero in a cryogenic environment without loss, and obtains a desired magnetic field for a predetermined period from a single charge from the outside. This is applied to a superconducting magnet system such as MRI, NMR, etc., and once fully charged, it is completely separated from the power supply from the outside and operated in a superconducting permanent current state.

The superconducting permanent current switch provided in superconducting magnet system such as MRI, NMR, etc. converts the superconducting magnet system from the normal charging state into the superconducting permanent current operating state, or heats the superconducting wire with a heater to exceed the critical temperature of the superconducting wire. By raising the temperature, the superconducting state is transferred to the phase conduction state, that is, performing a function of generating a quench to have a desired resistance. A brief description will be given of a conventional method of manufacturing a superconducting permanent current switch. Is as follows.

First, a bobbin capable of winding a superconducting wire is made of glass fiber reinforced plastic (FRP) or aluminum, which is made of a nonmagnetic material, and CuNi has a high specific resistance in order to easily obtain a high resistance value even at a very low temperature even at cryogenic temperatures. The NbTi superconducting wire which used as a stabilizing material is wound to minimize inductance. The heater for raising the internal temperature of the superconducting permanent current switch can be manufactured in various forms, for example, a method of winding the heater wire intensively on the bobbin, with a part of the superconducting wire, or at the end of the superconducting wire. Etc. After winding the superconducting wire and the heater wire, the superconducting of the superconducting permanent current switch in the environment of 4.2K which is the temperature of liquid helium so that the heat given to the superconducting wire by the heater is not lost to the surrounding liquid helium. The wire part is wrapped with insulation. The heat insulation part is designed to raise the temperature of the superconducting wire to a temperature at which the superconducting wire can have a desired resistance value according to the characteristics of the heat insulating material, and the heat insulating part is usually designed after winding a superconducting wire for a superconducting permanent current switch to a bobbin. It is impregnated with epoxy.

However, as a conventional superconducting permanent current switch wire manufactured as described above, an NbTi wire using CuNi as a stabilizing material is used, which is stronger than a NbTi wire using general copper as a stabilizing material. It is relatively difficult to recommend because it has a disadvantage. In particular, in order to wind the bifilar, which is a non-inductive winding, to have a minimum inductance, two wires should be wound in pairs so that currents flow in opposite directions. A conventional conventional superconducting winding device has a superconducting permanent point. Since the bobbin for supplying the superconducting wire, which is wound around the superconducting wire to be wound on the current switch bobbin, is composed of one, the winding tension given to the paired superconducting wire during winding is different, which makes it difficult to accurately align the winding. It was implicated.

In addition, conventionally, when bending the intermediate point of the entire length of the wire to be wound for the bi-filler winding to pair the wires of the two wires, it is difficult to bend due to the strong tension, and damage to the wires if artificially bent with a strong force This results in degradation of performance such as lowering of the critical current of the wire rod, and the pair of wires are wound in pairs so that the wire of the strong tension is simply inserted into the gap of the bobbin blade and fixed at the beginning of the winding. There was a problem that was very difficult to do.

In addition, in order to form the insulation after the superconducting wire winding of the superconducting permanent current switch is finished, the bobbin is separated from the winding machine and impregnated with epoxy, in which a mold is required to impregnate with a certain thickness. There is the inconvenience of manual work, and the superconducting permanent current switch, once impregnated with epoxy, has a disadvantage in that it is not flexible because it is impossible to make corrections due to manufacturing mistakes and after performance evaluation.

The present invention was created to solve the above-mentioned conventional problems, the object of which is to transfer the heat of the heater to a large area rapidly even with the same amount of heater wire winding as before, and initial bobbin without separating the winding machine It is to provide a superconducting permanent current switch configured to enable continuous operation from the winding of the superconducting wire, which is a process, to the process of forming the heat insulating part, which is the final process, and to facilitate modification after the completion of the heat insulating part, which is the final process.

Another object of the present invention is to prevent the damage of the wire rod generated when bending the intermediate point of the entire length of the wire to be wound during the bi-pillar induction winding of the superconducting permanent current switch, and the wire end is discharged to the outside after winding It is an object of the present invention to provide a bobbin for a superconducting permanent current switch, which is capable of finishing cleanly and firmly.

Another object of the present invention is to make the same tension between the two wires of the pair of wires in the bi-filler induction winding of the superconducting permanent current switch, and to minimize the movement due to the deterioration of the wires to be wound It is an object of the present invention to provide a winding device for a superconducting permanent current switch.

Hereinafter, a superconducting permanent current switch, a bobbin and a winding device for the superconducting permanent current switch according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram of a superconducting magnet system, as shown in the figure, a superconducting coil (110-113) wound for each section, a protection resistor (120-123) for the protection of the superconducting coil in Kuenchi, Superconducting permanent current switch (13) for charging and discharging the magnet and entering the permanent current mode, and the cryogenic vessel (14) for maintaining all the components (110-113, 120-123, 13) to 4.2K, the temperature of the liquid helium Consists of.

In the circuit connection relationship, each of the superconducting coils 110-113 is connected in series with each other, and the protection resistors 120-123 are connected in parallel with each of the coils 110-113, so that the Cuenchi system The energy stored in the superconducting coils 110-113 is exhausted. In addition, the superconducting permanent current switch 13 is connected in parallel to the circuit consisting of the superconducting coil (110-113) and the protection resistor (120-123). The connection of the superconducting wires to each other is bonded by an extremely low resistance superconducting junction 17 having a connection resistance of 10 ⁻⁹ or less to enable a long time permanent current mode operation.

Permanent current mode operation of the superconducting magnet is performed in the following order.

In the cryogenic vessel, the superconducting coils 110-113 and the superconducting permanent current switch 13 are cooled by liquid helium, which is a refrigerant, to be in a superconducting state. First, a current flows to the heater 132 through the heater lead wire 16 of the superconducting permanent current switch 13 to quench the superconducting coil 131 of the superconducting permanent current switch 13. When the superconducting permanent current switch 13 has a resistance value designed, charging is started by supplying an operating current through which the superconducting magnet generates a desired magnetic field through the current inlet line 15 of the superconducting magnet system. At this time, the supplied current flows only toward the superconducting coils 110-113 connected in series because the superconducting permanent current switch 13 and the protection resistors 120-123 have a constant resistance value. When the magnet reaches the operation current value and operates, the heater current supplied to the heater 131 is stopped, so that the superconducting permanent current switch 13 quickly switches back to the superconducting state, and the resistance becomes zero. At this time, the current flowing through the power supply and the superconducting magnet instantaneously flows through the superconducting permanent current switch 13, and the supplied current is the superconducting coil of the superconducting magnet (110-113) and the superconducting permanent current switch (13) of the superconducting magnet ( 131 flows into the closed circuit phase and enters the permanent current mode. After entering the permanent current mode, the external power supply is no longer needed, thus disconnecting the external power supply from the superconducting magnet system. This results in a superconducting magnet system that independently maintains the desired magnetic field for a long time and operates in superconducting permanent current mode.

In the superconducting permanent current switch according to the present invention, as shown in FIGS. 2 and 3, a bobbin 21 and a superconducting wire are wound around the bobbin 21 by a bifilar. A first superconducting winding layer 25a, a heater winding layer 32 formed by winding a conductive wire material on the first superconducting winding layer 25a by a bi-filler, and a superconducting wire material is formed on the heater winding layer 32. A second superconducting winding layer 25b formed by winding with a filler, and a heat insulating layer 31 formed by winding an insulating tape on the second superconducting winding layer 25b. In addition, as shown in FIG. 4, a heat conductive layer 51 formed by winding a metal tape having excellent thermal conductivity between the heater winding layer 32 and the first and / or second superconducting winding layers 25a and 25b. It is preferably configured to further include, the heater winding layer 32 is preferably wound so that the winding density is concentrated at the central portion in the longitudinal direction of the bobbin 21 and the winding density decreases toward both flanges.

More specifically, the inductance of NbTi superconducting wires having CuNi as a stabilizing material with a high specific resistance to the bobbin 21 made of a non-magnetic material such as glass fiber reinforced plastic (FRP) or insulated aluminum which does not affect the magnetic field at all. A bifilar non-inductive winding is minimized to form the superconducting winding layers 25a and 25b. At this time, when the bobbin 21 made of a conductor material such as aluminum is used, the winding on the surface of the bobbin 21 is insulated as thin as a capton tape which is thin enough to have little influence but excellent in insulation. A heater winding layer 32 for quenching the superconducting winding layers 25a and 25b is formed in an intermediate layer of the superconducting winding layer 25a.

In this case, the heater winding layer 32 is a middle layer of the superconducting winding layer (25a, 25b) laid a layer of metal tape 51 having excellent thermal conductivity, such as copper or aluminum tape, and wound the heater wire 131 thereon To configure.

The heater wire 131 is tightly wound on both sides of the bobbin 21 from the longitudinal center of the bobbin 21 on the metal tape 51 so as to be concentrated at the center of the bobbin 21. This is to give a high heater heat in the center of the superconducting winding layer (25a, 25b) by the limited amount of heater wire 131 due to the limitation of the heater power, etc., the superconducting winding layer (25a) so that this concentrated heat And metal tape having excellent thermal conductivity to quickly propagate to a large area of (25b).

After the windings of the superconducting winding layers 25a and 25b are finished, a low temperature epoxy (stycast) is lightly applied to fix the windings. Low temperature epoxies are thermally very good thermal conductivity and electrically insulating agents.

On the outer surface of the superconducting winding layer 25b, a heat insulation layer 31 is formed to block the heat of the heater winding layer 32 from being lost to the surrounding liquid helium, thereby reducing the temperature of the superconducting winding layers 25a and 25b. It allows you to maintain the temperature at which Cuencich can occur. Various heat insulating materials constituting the heat insulating layer 31 may be used. In general, when a material having a low thermal conductivity is used, the volume of the heat insulating portion may be reduced.

In the present invention, as an example, the heat insulation layer 31 is formed by using a cotton-rubber tape. Cotton-rubber tape is generally used for electrical insulation and has a slight viscosity. The thermal insulation layer 31 is wound while applying a certain tension by hand on the winding machine in which the superconducting permanent current switch of the superconducting winding is fixed in consideration of the width of the surface-rubber tape. Therefore, the process is very simple and easy compared with the conventional method of separating from the winding machine and impregnating with epoxy to insulate.

When winding the insulation layer 31 by applying a thin layer of low-temperature epoxy in the winding intermediate layer of the insulation layer 31, it serves to fix the winding of the cotton-rubber tape therein. The rest is wound up to the design thickness and then epoxy fixed for low temperature.

When the heat insulation layer 31 is completed as described above, the low temperature epoxy cured with a thin film may be easily removed by unwinding or further winding the cotton-rubber tape when a thickness correction is needed.

The wire 25 inserted through the winding introduction hole 61 and the two strands are formed as a pair is collected through the guide pipe 24 and then each strand is connected to the pair of rollers 221 and 222 to provide a constant tension. While maintaining, it is to be wound around the pair of wire supply bobbins (231, 232) by half of the total superconducting wire length, respectively.
