Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of embodiments in many different forms than those described herein and those skilled in the art will be able to make similar modifications without departing from the spirit of the application and it is therefore not intended to be limited to the embodiments disclosed below.
it will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
One embodiment of the present application provides a winding structure 10 for high temperature superconducting tape. The winding structure 10 of the high temperature superconducting tape includes at least two layers of superconducting tapes 100.
the first layer of superconducting tape 101 is wound around the shaft structure 110 at a predetermined helix angle. And forming a gap region 112 on the shaft structure 110. The second layer of superconducting tape 102 is wound around the shaft structure 110 at the predetermined pitch angle. The shaft structure 110 may be a solid, flexible skeleton. The axis structure 110 may be a virtual axis. When the shaft structure 110 is a virtual shaft, the winding structure 10 of the high temperature superconducting tape is a hollow structure. Wherein the second layer of superconducting tape 102 partially covers the first layer of superconducting tape 101, and the remaining portion of the second layer of superconducting tape 102 covers the gap region 112. The remaining superconducting tapes 100 of the at least two layers of superconducting tapes 100 are wound around the shaft structure 110 in the same winding manner as the second layer of superconducting tapes 102, so that the gap region 112 is completely covered.
Each layer of the superconducting tape 100 has a long strip shape having a certain width. The superconducting tape is wound around the shaft structure 110 at an angle in a length direction. Referring to fig. 1, a layer of superconducting tape 100 is wound around the shaft structure 110. Since the superconducting tape 100 is wound in a spiral manner, a gap region 112 is formed on the shaft structure 110 without being wrapped by the tape. When a three-phase high-temperature superconducting current conductor is prepared, each phase superconducting layer may be formed by winding a plurality of superconducting tapes 100 around a flexible former. As shown in fig. 2, a structure in which a superconducting layer of one phase is wound from 3 superconducting tapes is shown. The three superconducting tapes 100 are wound at the same spiral angle, and when the second superconducting tape 100 is wound, a part of the second superconducting tape is wound to overlap with the first superconducting tape 100 along the width direction, and the other part of the second superconducting tape covers a part of the gap region 112. When being wound, the third superconducting tape 100 is partially wound to overlap with the second superconducting tape 100 in the width direction, and the other part covers the gap region 112 of the remaining part.
The winding structure 10 of the high temperature superconducting tape includes at least two layers of superconducting tapes 100. One layer of the superconducting tape 100 is lapped over another layer of the superconducting tape 100. That is, when one layer of the superconducting tape 100 is wound on the framework of the high-temperature superconducting current conductor, the other layers of the superconducting tape 100 are aligned with the gap of the previous layer of the tape, and are wound in an inserting manner. The vertical component of the magnetic field of the adjacent superconducting tapes of the winding structure 10 of the high-temperature superconducting tape is partially offset, which is helpful for homogenizing the magnetic field and eliminating the influence of the vertical field.
In one embodiment, the second layer of superconducting tape 102 covers 1/3 to 2/3 of the first layer of superconducting tape 101. In an alternative embodiment, the second layer of superconducting tape 100 is coated on 1/2 of the first layer of superconducting tape 101. That is, when the first layer of superconducting tape 101 is wound around the shaft structure 110 at a predetermined helix angle, one long side of the second layer of superconducting tape 102 coincides with the central axis of the first layer of superconducting tape 101. In one embodiment, the at least two layers of superconducting tape 100 further comprises a third layer of superconducting tape 103. The third layer of superconducting tape 103 is coated on 1/3 of the second layer of superconducting tape 102, and the gap region 112 is completely coated. It is understood that the winding structure 10 of the high temperature superconducting tape may include not only the triple-layered superconducting tape 100 but also the multi-layered superconducting tape 100. As long as the winding manner of the winding structure 10 of the high-temperature superconducting tape is the slot winding, it should be considered to be within the scope of the present application.
Referring to fig. 3, the present application provides a high temperature superconducting current conductor 20. The high-temperature superconducting current conductor 20 includes at least a former 200, four insulating layers, and three superconducting layers. The four insulating layers are a first insulating layer 310, a second insulating layer 320, a third insulating layer 330, and a fourth insulating layer 340. The three superconductive layers are a first superconductive layer 410, a second superconductive layer 420, and a third superconductive layer 430.
the first insulating layer 310 is wound around the bobbin 200. The first superconducting layer 410 includes the wound structure 10 of the high-temperature superconducting tape according to any one of the above embodiments. The first superconducting layer 410 is wound around the former 200 at a first predetermined helix angle. The second insulating layer 320 is wound around the first superconducting layer 410. The second superconducting layer 420 includes the wound structure 10 of the high-temperature superconducting tape according to any one of the above embodiments. The second superconducting layer 420 is wound around the second insulating layer 320 at a second predetermined spiral angle. In one embodiment, to reduce the axial magnetic field, the first predetermined helix angle and the second predetermined helix angle are complementary with respect to normal. The normal line is a line perpendicular to the length direction of the frame 200. The third insulating layer 330 is wound around the second superconducting layer 420. The third superconducting layer 430 includes the wound structure 10 of the high-temperature superconducting tape according to any one of the above embodiments. The third superconducting layer 430 is wound around the third insulating layer 330 at the first predetermined spiral angle. A fourth insulating layer 340 is wound around the third superconducting layer 430.
the innermost side of the high-temperature superconducting current-carrying conductor 20 is a framework 200 for winding a superconducting tape 100 and serving as a refrigerating working medium channel. The backbone 200 may have some flexibility and rigidity due to some bending of the cables during transportation and installation. The frame 200 may be a corrugated tube made of stainless steel.
insulation structures are required to be wound between the skeleton 200 and the first superconducting layer 410, between the first superconducting layer 410 and the second superconducting layer 420, between the second superconducting layer 420 and the third superconducting layer 430, and outside the third superconducting layer 430 to isolate the ground layer from each superconducting layer in the current-carrying conductor. Since the high-temperature superconducting current conductor 20 is a low-temperature insulating structure in the present application, the insulating layer needs to be made of a material that can resist low temperature. The thickness of each insulating layer can be designed according to the withstand voltage class. In an alternative embodiment, the insulating layer may be polypropylene laminated paper (PPLP). The polypropylene laminated paper is of a three-layer structure, the outer two layers are wood fiber paper, and the inner layer is polypropylene.
each superconducting layer of the above-mentioned high-temperature superconducting current conductor 20 includes at least two superconducting tapes 100. One layer of the superconducting tape 100 is lapped over another layer of the superconducting tape 100. That is, when one layer of the superconducting tape 100 is wound on the former of the high temperature superconducting current conductor 20, the other layers of the superconducting tape 100 are aligned with the gap of the previous layer of the tape, and are wound in an inserting manner. The vertical component of the magnetic field of the adjacent superconducting tapes of the high-temperature superconducting current conductor 20 is partially offset, which helps to homogenize the magnetic field and eliminate the influence of the vertical field.
In one embodiment, the first superconducting layer 410, the second superconducting layer 420, and the third superconducting layer 430 include the same number of superconducting tapes 100. That is, the three-phase superconducting layers in the high-temperature superconducting current conductor 20 have the same structure, and in this structure, the vertical components of the magnetic fields of the adjacent superconducting tapes are partially cancelled out, which helps to homogenize the magnetic fields and eliminate the influence of the vertical fields.
referring to fig. 4, in one embodiment, the high-temperature superconducting current conductor 20 further includes a plurality of copper stabilization layers, which are a first copper stabilization layer 510, a second copper stabilization layer 520, and a third copper stabilization layer 530. The first copper stabilization layer 510 is wound around the first insulating layer 310. And the first copper stabilization layer 510 is located between the first insulating layer 310 and the first superconducting layer 410. The second copper stabilization layer 520 is wound around the second insulation layer 320. And the second copper stabilization layer 520 is located between the second insulation layer 320 and the second superconducting layer 420. The third copper stabilization layer 530 is wound around the third insulation layer 330. And the third copper stabilization layer 530 is located between the third insulation layer 330 and the third superconducting layer 430.
in this embodiment, the plurality of copper stabilization layers may be copper layers. During operation of the cable, once the insulation between the superconducting layers in the high-temperature superconducting current conductor 20 and between the superconducting layers and the ground is damaged, a large short-circuit fault current flows through the conductor layers, so that the temperature rises rapidly and further the insulation and the sheath are threatened. The laying of the multiple copper stabilizing layers can prevent fault current from causing larger damage to the cable body. The multilayer copper stabilization layer can smoothly pass a huge fault current in a short time without generating too large temperature rise. And winding the superconducting layers at a certain angle on the surfaces of the multiple copper stable layers to form spiral structures. When the number of the superconducting strips is too large, multilayer winding can be carried out, and a winding layer can be added between the superconducting layers to ensure that the winding surface is as flat as possible.
In one embodiment, the high-temperature superconducting electrical conductor 20 further comprises a plurality of semiconducting layers. The plurality of semiconductive layers are a first semiconductive layer 610, a second semiconductive layer 620, a third semiconductive layer 630, a fourth semiconductive layer 640, a fifth semiconductive layer 650, a sixth semiconductive layer 660, a seventh semiconductive layer 670, and an eighth semiconductive layer 680.
the first semiconductor layer 610 is wound around the bobbin 200, and the first semiconductor layer 610 is located between the bobbin 200 and the first insulating layer 310. The second semiconducting layer 620 is wound around the first insulating layer 310, and the second semiconducting layer 620 is located between the first insulating layer 310 and the first copper stabilization layer 510. The third semiconducting layer 630 is wound around the first superconducting layer 410, and the third semiconducting layer 630 is located between the second insulating layer 320 and the first superconducting layer 410. The fourth semiconductor layer 640 is wound around the second insulating layer 320, and the fourth semiconductor layer 640 is located between the second insulating layer 320 and the second copper stable layer 520. The fifth semiconductive layer 650 is wound around the second superconducting layer 420, and the fifth semiconductive layer 650 is located between the third insulating layer 330 and the second superconducting layer 420. The sixth semiconducting layer 660 is wound around the third insulating layer 330, and the sixth semiconducting layer 660 is located between the third insulating layer 330 and the third copper stabilization layer 530. The seventh semiconductive layer 670 is wound around the third superconducting layer 430, and the seventh semiconductive layer 670 is located between the fourth insulating layer 340 and the third superconducting layer 430. The eighth semiconductor layer 680 is wound around the fourth insulating layer 340, and the eighth semiconductor layer 680 and the seventh semiconductor layer 670 are respectively disposed on two sides of the fourth insulating layer 340.
In this embodiment, in order to prevent the insulation breakdown caused by the over-concentration of local charges, a semi-conducting layer is wound around each of the inside and outside of the insulating layer to make the electric field uniform. The semiconducting layer may be carbon paper.
