Description

{Fault current limiter having super-conductor tape winding structure to decrease inductance and method for manufacturing the same}

The present invention relates to a superconducting tape winding technology, and more specifically, to a current limiter having a superconducting tape winding structure for reducing inductance.

In addition, the present invention relates to a tape winding method for a resistive superconducting current limiter that can be miniaturized by preventing a decrease in critical current and increasing space utilization.

Recently, due to the continuous increase in the load of the power system, the level of fault current expected in the event of an accident is increasing. Accordingly, the development of a current limiter is required to assist the fast and stable breaking operation of the circuit breaker and to reduce the fault current.

Current limiters have been developed in the form of superconducting current limiters. Superconductors are in a superconducting state within the critical temperature, critical magnetic field, and critical current density, so they exhibit the characteristic of having zero electrical resistance. However, when the critical value is exceeded, they exhibit the characteristic of having a large resistance along with a quench phenomenon.

Due to these characteristics, when a superconducting current limiter is connected in series to a system, the superconducting current limiter can conduct current without loss because it maintains zero resistance in the normal state of the system.

However, when the fault current exceeds the critical current of the superconductor in a transient state of the system, the resistance of the superconductor increases rapidly, which can lower the level of the fault current.

When current flows through a superconducting tape, hysteresis loss occurs. Hysteresis loss is divided into self-field loss and external magnetic field loss, and this magnetic field loss adds inductance to the system and adversely affects the critical magnetic field characteristics of the superconducting material.

For this purpose, a non-inductive winding method is generally adopted for resistive superconducting current limiters. This is a method that minimizes losses due to inductance by reversing the current direction of adjacent tapes to cancel out the magnetic field.

According to the arrangement or winding method of the superconducting tape, the resistive superconducting current limiter is typically divided into the meander type (see Fig. 1) and the bi-filar pancake type (see Fig. 2).

As shown in Fig. 1, in the meander type, superconducting tapes are connected through terminals with high conductivity so that current flows in a zigzag pattern. Since the current directions of adjacent tapes are opposite, the magnetic flux is canceled out, which can reduce inductance.

However, since it is relatively difficult to manufacture and has low space utilization, its volume may increase when applied to a large-capacity current limiter. In addition, the contact resistance between the tape and the terminal causes heat loss (I ² R) in the superconducting state.

Meanwhile, as shown in Fig. 2, the bi-pillar pancake type is a method in which the superconducting tape is wound spirally in the form of a double coil. Since the current directions of adjacent tapes in the vertically arranged double coil are opposite, the magnetic fluxes cancel each other out, which can reduce the inductance caused by the overall shape of the superconducting tape.

In addition, since the amount of superconductor used is greater than that of other methods of the same volume, space utilization is high. However, since there is almost no space between adjacent tapes, the contact surface between the tape and LN ₂ is small, and it is difficult to diffuse bubbles due to heat during ?? treatment, so the recovery characteristics may be deteriorated. Therefore, there is a disadvantage that a spacer made of a special material must be used to increase the contact surface between the tape and LN ₂ .

In order to solve the mentioned problems, there is a need to develop a new type of resistive superconducting current limiter and improve the mentioned problems.

FIG. 3A is a conceptual diagram of a resistive superconducting current limiter (300) of a multi-filar meander type configured by utilizing six insulators according to one embodiment of the present invention. Referring to FIG. 3A, the resistive superconducting current limiter (300) is configured with first to sixth insulators (320-1 to 320-n) and a superconducting tape (310) wound on a portion of the outer surface of the first to sixth insulators (320-1 to 320-n).

Among the first to sixth insulators (320-1 to 320-n), the first insulator (320-1), the second insulator (320-2), the fifth insulator (320-5), and the sixth insulator (320-6) are arranged horizontally spaced apart from each other by a 1-1 interval.

Among the first to sixth insulators (320-1 to 320-n), the third insulator (320-3) and the fourth insulator (320-4) are arranged to be spaced apart from each other by a 1-2 interval. At this time, the 1-2 interval is larger than the 1-1 interval.

Additionally, the third insulator (320-3) and the fourth insulator (320-4) are arranged vertically spaced apart from the first insulator (320-1), the second insulator (320-2), the fifth insulator (320-5), and the sixth insulator (320-6) by a constant second interval.

The first to sixth insulators (320-1 to 320-n) are cylindrical insulators with a diameter of about 10 mm. Materials for the insulating materials may include engineering plastics, wood, paper, and compressed rubber.

In Fig. 3a, six insulators are used as an example, but this is not limited thereto, and depending on the capacity of the superconducting current limiter and the environment of the cooling facility, more cylindrical insulators may be used, and the spacing between each insulator may increase or decrease.

Fig. 3b is a structural diagram of the superconducting tape (310) illustrated in Fig. 3a. Referring to Fig. 3b, in order to secure insulation, the outermost layer of the superconducting tape (310) must be coated with a material having excellent heat resistance and/or electrical insulation, and the superconducting tape is configured in a vertical arrangement.

In detail, the superconducting tape (310) is formed of a substrate (301), a buffer layer (302) formed on the surface of the substrate (301), a first metal layer (303) formed on the surface of the buffer layer (302), a second metal layer (304) formed on the surface of the first metal layer (303), a third metal layer (305) formed on the surface of the second metal layer (304), and a coating layer (306) formed on the surface of the third metal layer (305).

이고, 약 0.7μm의 두께이다.The substrate (301) is made of a nickel-chromium-iron-molybdenum alloy (Hastelloy) and has a thickness of about 50 μm. The buffer layer (302) is made of a material

, and has a thickness of approximately 0.7 μm.

The first metal layer (303) is GdBCo and has a thickness of about 1.3 μm, the second metal layer (304) is silver and has a thickness of about 2.0 μm, and the third metal layer (305) is copper and has a thickness of about 15 μm. The coating layer (306) is polyamide and has a thickness of about 50 μm.

Figures 4 to 7 are winding process diagrams of a multi-filar meander type resistive superconducting current limiter illustrated in Figure 3. First, the first to sixth insulators (320-1 to 320-n) are arranged.

Thereafter, as shown in Fig. 4, half (1/2) of the total length of the superconducting tape (310) to be used is wound around the first insulator (320-1).

Thereafter, as shown in Fig. 5, the last sixth insulator (320-6) is wound and fixed at the position of the sixth insulator (320-6).

Thereafter, as shown in Fig. 6, the position of the first insulator (320-1) is moved. In detail, the position of the first insulator (320-1) is moved to the left in the horizontal direction based on the drawing while rotating the position of the first insulator (320-1) toward the outside of the sixth insulator (320-6) based on the sixth insulator (320-6).

Thereafter, as shown in Fig. 7, the fifth insulator (320-5) to the second insulator (320-2) are sequentially inserted and placed between the first insulator (320-1) and the sixth insulator (320-6), and the position of each insulator is fixed as shown in Fig. 3.

When designing a superconducting current limiter, the amount of inductance generated, the depth of magnetic field penetration, and the recovery characteristics are affected by the type and arrangement of superconducting tapes. In one embodiment of the present invention, four superconducting tapes with different current directions are adjacent to each other in one path.

Figures 8 to 10 show the self-inductance, mutual inductance, and magnetic flux of each path according to the arrangement of four superconducting tapes.

In particular, Fig. 8 is a graph showing inductance and magnetic flux when the direction of current flowing in adjacent superconducting tapes in a parallel arrangement is the same. Referring to Fig. 8, inductance and magnetic flux are shown when the direction of current flowing in adjacent superconducting tapes in a parallel arrangement is the same.

Since the current direction is the same in all paths, the magnetic fields do not cancel each other out, which generates relatively high inductance and magnetic fields. When winding tens of kilometers of superconducting tape with this arrangement, the superconducting current limiter will have high inductance, and the strong magnetic flux will adversely affect the critical characteristics of the adjacent superconducting tape.

Fig. 9 is a graph showing inductance and magnetic flux when the double array tapes are arranged in parallel and the directions of current flowing in four adjacent superconducting tapes are opposite. Referring to Fig. 9, inductance and magnetic flux are shown when the double array tapes are arranged in parallel and the directions of current flowing in four adjacent superconducting tapes are opposite.

Since the current directions in all adjacent superconducting tapes are opposite, the magnetic flux can be effectively canceled.

Fig. 10 is a graph showing inductance and magnetic flux when the double array tapes are arranged vertically and the current flowing in the four adjacent superconducting tapes is in the opposite direction. Referring to Fig. 10, the inductance and magnetic flux are shown when the double array tapes are arranged vertically and the current flowing in the four adjacent superconducting tapes is in the opposite direction.

In this case, it is possible to have lower inductance and magnetic field than in a parallel arrangement.

Fig. 11 is a perspective view of a superconducting current limiter (1100) having four superconducting tapes (1130) adjacent to each other according to an embodiment of the present invention. Referring to Fig. 11, if superconducting tapes (1130) with secured insulation are wound as in the example above, as shown in (a) of Fig. 11, a maximum of four superconducting tapes can be adjacent to each other in one path.

At this time, the direction of the current of each wire is as shown in Fig. 11b. The current of the four adjacent tapes is generated in the incoming and outgoing directions alternately. Therefore, since they flow in opposite directions, the inductance caused by the shape of the tape can be minimized.

In addition, as illustrated in Fig. 11, a superconducting current limiter (1100) is configured with a support (1110) to which six or more insulators (1120) are fixed.

FIG. 12 is a perspective view of a support (1110) for adjusting the spacing of the insulator illustrated in FIG. 11. Referring to FIG. 12, in order to effectively prevent bubble diffusion during a quench (meaning that a superconducting state is irreversibly and uncontrollably transferred to a normal conducting state in a superconductor or a superconducting device) and to adjust the spacing of the cylindrical insulator, first grooves (1210-1) and second grooves (1210-2) having a constant straight length are alternately formed on the surface of the support (1110). Of course, the length of the second groove (1210-2) is greater than the length of the first groove (1210-1). This structure of the support (1110) is also applied to the superconducting current limiter illustrated in FIG. 3.

In practical use, superconducting current limiters can be connected in series or parallel, considering the critical current of the superconducting tape and the rated current of the system. Superconducting tape can exist in a state where the electrical resistance is almost zero at cryogenic temperatures.

In normal conditions, the current is passed within the critical value of the superconducting tape, so the superconducting current limiter can pass the current without loss by maintaining very low inductance and zero resistance. In case of an accident, if the accident current exceeds the critical value of the superconducting tape, the superconducting tape will break down and generate resistance.

This ??chi resistance can effectively limit the fault current to protect power devices and converters. When the fault is interrupted and the system current becomes smaller than the critical current of the superconducting tape, the superconducting tape recovers and changes to a superconducting state again, maintaining zero resistance.

Fig. 13 is a perspective view of a superconducting current limiter configured with two superconducting tapes in an upper and lower configuration according to another embodiment of the present invention. As shown in (a) of Fig. 13, the superconducting tapes are configured with an upper superconducting tape (1311) and a lower superconducting tape (1312) that is separated from the upper superconducting tape (1311) and arranged parallel to it. The two tapes can be arranged in an upper and lower configuration. At this time, the direction of current flowing in one path is as shown in (b) of Fig. 13.

When configured in this manner, the height increases, but because it is configured in a vertical arrangement, there is an advantage in that magnetic field penetration within the superconducting tape is improved.

FIG. 14 is a conceptual diagram of a superconducting current limiter in which multiple layers of auxiliary insulating material (1410) are added horizontally while maintaining the thickness interval of the superconducting tape in a cylindrical insulator according to another embodiment of the present invention.

Referring to Fig. 14, multiple layers of auxiliary insulating material (1410) can be added horizontally to a portion of the outer surface of a cylindrical insulator on which a superconducting tape is wound, so as to maintain the thickness gap of the superconducting tape. This structure has high stability because it can secure insulation between adjacent tapes without coating the superconducting tape with an insulating material. The material of the auxiliary insulating material (1410) can be compressed rubber, plastic, paper, etc.

Fig. 15 is a superconducting current limiter having a multilayer structure according to another embodiment of the present invention. Referring to Fig. 15, in order to apply the superconducting current limiter to a system, several (i.e., 2) to several dozen (i.e., 99) layers can be connected in series or in parallel.

To elaborate, the insulator, the superconducting tape wound on the insulator, and the support for fixing the insulator are made into one layer, and several to several dozen of these layers are connected in series or in parallel.
