Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1. It should be understood that the structures, ratios, sizes, etc. shown in the drawings of the present specification are only used for matching with the contents disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any modification of the structures, changes of the ratio relationship, or adjustment of the sizes should still fall within the scope covered by the technical contents disclosed in the present invention without affecting the efficacy and the achievable purpose of the present invention. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
As shown in fig. 1, the present invention provides a superconducting tape, the superconducting tape 1 has a plurality of scratch groups (e.g. scratch group one 101 and scratch group two 102) thereon, all scratch groups are along the length direction of the superconducting tape 1 is distributed, each scratch group has a plurality of scratches 11 which are parallel to each other and all divide the superconducting surface of the superconducting tape 1 (even if the superconducting surface at this position loses superconductivity), and the adjacent scratch groups have an interval 103, and each scratch 11 in the adjacent scratch groups is mutually dislocated. The utility model discloses a set up a plurality of mar groups on superconducting tape 1 to this makes the mar 11 on superconducting tape 1 be the off-state, and each mar 11 in the adjacent mar group misplaces each other, so make superconducting tape 1 go up to form superconducting channel 12 of multiple combination mode, superconducting channel 12 in this specification indicates the superconducting tape between adjacent mar 11, the superconductive transmission's that is cut apart to form passageway promptly, superconducting channel 12 that the mar 11 formed in present group (like mar group one 101), when getting into next region, all superconducting channel 12 fold through interval 102 department, the superconducting channel 12 that the mar formed in next group (like mar group two 102) of reentrant, because the dislocation of each mar 11 in the adjacent group, then superconducting channel 12 of present group can just be to two (or more) superconducting channel 12 when getting into next group's superconducting channel 12, even one of them superconducting channel 12 is not logical in next group, it does not affect the transmission, so it ensures the conductivity of the superconducting tape while reducing the ac loss.
The superconducting tape 1 in this embodiment is a long raw material, and the length thereof can be 1KM or even longer.
In order to better provide superconductivity, the number of scratches in the adjacent scratch groups in the embodiment is different, in the embodiment, 4 scratches 11 are arranged in the second scratch group 102, and the number of scratches in the first scratch group 101 is 3, so that the conductivity of the superconducting tape in the width direction is improved by a combination mode of increasing superconducting channels through different numbers in the adjacent groups. The number of the scratches in the adjacent scratch groups can be the same, and only the scratches need to be arranged in a staggered manner.
For ease of implementation, all scratches in each of the scratch groups have a length of 1cm to 10 m. The spacing between adjacent scratch groups is typically less than 1cm in length. All scratches in each scratch group are distributed at equal intervals, and the intervals among the scratches in all groups are also the same. Every among the mar group, all the mar is equidistant distribution, and the interval is less than 1 mm.
In order to facilitate the formation of the above-mentioned superconducting tapes, two different processing techniques are given below:
1) and cutting the base material on which the superconducting tape is formed to form the scratch group, and forming a coating on the surface of the base material with the scratch group through a coating process. The embodiment is characterized in that the process of machining the scratch first and then coating is adopted, and the superconducting surface cannot be formed at the scratch position when the coating is coated due to the existence of the scratch.
2) And forming a coating on the substrate through a coating process, and cutting and damaging the coating on the surface with the coating to form the scratch group. In the embodiment, on the basis of the coated superconducting strip, a plurality of scratches are cut on the surface of the coating along the length direction, so that the positions of the scratches lose the superconducting capacity. No matter what kind of processing technology is adopted, the superconducting tape at the scratch position is lost superconductivity, so that the whole superconducting channel of the superconducting tape is cut into a plurality of superconducting channels, the path of each superconducting channel is variable, the alternating current loss is effectively reduced, and the quality of the superconducting tape is improved. The scratches may be made by laser cutting or engraving.
To sum up, the utility model discloses a superconductive tape, its continuity of having ensured superconductive tape when reducing the alternating current loss. Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.
