By adopting the compressed superconducting cable for nuclear fusion, the problems of falling off of a superconducting strand coating, damage and fracture of superconducting wires, non-uniform porosity and fracture of a nylon material compression wheel caused by compression by a steel wheel can be avoided, and the compressed superconducting cable for nuclear fusion can completely meet the requirement of technical specifications.
Description
Technical Field
The invention relates to the technical field of superconducting cables, in particular to a superconducting cable combined reinforced type pinch roller for a nuclear fusion device.
Background
Because the superconducting cable hardly generates heat when in a superconducting state, and can lead the current to be very large without generating energy consumption under the condition of no quench, the superconducting cable has wide application prospect today emphasizing low-carbon economic development by the characteristics of zero resistance and complete diamagnetism, and is particularly applied to the winding of magnet coils in the field of high-energy physics and other fields.
The superconducting cable conductor for the nuclear fusion device is a multi-stage cable, a first-stage sub-cable of the conductor is formed by twisting a plurality of copper wires and a plurality of superconducting wires according to a certain twisting pitch, then a plurality of sub-cable units are twisted according to a certain twisting pitch to form a second-stage sub-cable, and a third-stage sub-cable and a fourth-stage sub-cable are formed in the same way and finally twisted into a five-stage super-cable. The stranded strands of the superconducting cable reach 1152, and the diameter of each superconducting strand is 0.82 +/-0.003 mm. Because the influence of the outer diameter of each cable and the void factor of the cable on the electromagnetic performance of the conductor is large, the control requirements of the stranding process of the cable conductor on the outer diameter of the cable and the void factor of the cable are very strict.
Since the design outer diameter of a superconducting cable for a nuclear fusion device is much smaller than the natural outer diameter of the cable stranding, an outer diameter reduction measure must be taken in the stranding of the cable. However, the superconducting wire is hard and has almost no elongation, for example, when the conventional steel pinch wheel is used for reducing the diameter of the superconducting cable conductor for the nuclear fusion device, a niobium coating on the surface of the superconducting strand is easily scraped off in the reducing process, the superconducting strand on the surface layer of the superconducting cable is easily deformed, the superconducting wire of the strand is easily broken, the void ratio of the strand on the surface layer is smaller than that of the strand on the inner layer, so that the void ratio of the cable is unbalanced, and the twisted superconducting cable cannot meet the technical specification of the superconducting cable for the nuclear fusion device.
Disclosure of Invention
The invention aims to provide a combined reinforced type compacting wheel of a superconducting cable for a nuclear fusion device, which solves the problems of the falling of a coating of a superconducting strand, the damage and the fracture of superconducting wires and the non-uniform porosity of the superconducting cable in the process of controlling the stranding compacting outer diameter.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a superconducting cable combination reinforced type pressing wheel for a nuclear fusion device comprises a steel reinforcing body, a nylon pressing body and a steel reinforcing body, wherein a bearing is installed in an inner hole of the steel reinforcing body, the nylon pressing body is sleeved on the outer portion of the steel reinforcing body and used for pressing the superconducting cable body, and the steel reinforcing body is tightly sleeved on the outer portion of the steel reinforcing body and used for enabling the nylon pressing body to be fastened on the steel reinforcing body and tightly abuts against the side edge.
As a further limitation of the present invention, the nylon compact and the steel reinforcing body are tightly fitted.
As a further limitation of the present invention, the nylon compaction body is provided with a compaction inner hole, the inner surface of which is in contact with the superconducting wires of the superconducting cable when compacting.
Preferably, the shape of the compaction inner hole is a half arc.
As a further limitation of the invention, the cross section of the steel reinforcing body is in a T shape, and the nylon pressing body and the steel reinforcing body are tightly sleeved at the middle part and the tail part of the T shape of the steel reinforcing body in turn at the side edges.
As a further limitation of the present invention, the steel reinforcing body is provided with a steel reinforcing body external screw thread, and the steel reinforcing body is tightly sleeved outside the steel reinforcing body in a manner that the steel reinforcing body is tightly screwed on the steel reinforcing body external screw thread by an internal screw arranged on the steel reinforcing body.
Compared with the prior art, the invention has the following beneficial effects:
the original superconducting cable pressing wheel is changed from a steel wheel into a nylon wheel, so that the problems that a cracked superconducting strand coating falls off, superconducting wires are damaged and broken and the pressing porosity is not uniform when the steel wheel is pressed can be solved; meanwhile, in order to prevent the nylon wheel from cracking due to insufficient strength of the nylon material during compression, the steel reinforced main body and the steel reinforced body are additionally arranged on the outer side of the nylon compression body and tightly clamped on the side edge, so that the combined reinforced compression wheel of the nylon reinforced sleeve is formed. The invention well realizes the compression of the superconducting cable and ensures that the performance of the superconducting cable completely meets the requirements of technical specifications.

Detailed Description
The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.
Examples
The invention provides a superconducting cable combined reinforced type pinch roller for a nuclear fusion device, which is used for compressing a superconducting cable, and mainly comprises a nylon compression body 1, a steel reinforcing body 3 and a steel reinforcing body external screw thread 5 in structure as shown in figures 1-5.
As shown in fig. 1 and 5, the nylon compression body 1 is used as a main body of the compressed superconducting cable in the present invention, and is made of nylon and sleeved on the steel reinforcing body 3 (in this embodiment, the nylon compression body 1 and the steel reinforcing body 3 are tightly fitted). The nylon compacting body 1 is provided with a compacting inner hole 2, and when the compacting wheel compacts the superconducting cable, the inner surface of the compacting inner hole 2 is contacted with the superconducting wire of the superconducting cable; in the embodiment, the shape of the compression inner hole 2 is preferably a semi-arc shape, the processing is simple, and the contact effect with the superconducting wire of the superconducting cable is good.
As shown in fig. 2 and 5, the steel reinforcing body fastening side 5 is tightly sleeved outside the steel reinforcing body 3, so that the nylon compacting body 1 is tightly fastened on the steel reinforcing body 3.
As shown in fig. 3, 4 and 5, in the present embodiment, the cross section of the steel reinforcing body 3 is "T" shaped, and a bearing 6 is installed in an inner hole thereof; the nylon compacting body 1 and the steel reinforcing body are tightly sleeved at the middle part and the tail part of the T shape of the steel reinforcing body by the tight side edges 5 in sequence. Furthermore, the steel reinforcing body 3 is provided with a steel reinforcing body external screw thread 4, and the steel reinforcing body tight side 5 is tightly sleeved outside the steel reinforcing body 3 in a manner that an internal screw arranged on the steel reinforcing body tight side is screwed on the steel reinforcing body external screw thread 4.
When the superconducting cable is used, the superconducting cable is sleeved on the pressing shaft (sleeved on the pressing shaft through the bearing 6), and then the superconducting cable is installed on the pressing seats in pairs to press the superconducting cable for the nuclear fusion device. During compression, the inner surface of the compression inner hole 2 is in contact with the superconducting wires of the compressed superconducting cable, and the nylon material is lower than the rigidity of the steel wheel, so that the problems of deformation, fracture and coating shedding of the superconducting wires cannot occur during compression, and meanwhile, the nylon compression body 1 is tightly embedded in the steel reinforcing body and the compression side 5 are fastened, and the phenomenon that the nylon compression body 1 is fractured due to the fact that the compression inner hole 2 is subjected to overlarge radial force cannot occur.
Tests show that the compressed superconducting cable for nuclear fusion has the advantages that the problems of falling of a coating of a superconducting strand, damage and breakage of superconducting wires and uneven porosity caused by compression by a steel wheel do not occur, and the problem of breakage of a nylon clamping wheel does not occur, so that the compressed superconducting cable for nuclear fusion completely meets the requirements of technical specifications.
The invention seems to be simple, is not easy to think in practice, and can effectively solve the difficult problem of the superconducting cable in practical application through simple and ingenious improvement only through deep research, thereby really achieving the effective balance between the cost and the technology. The invention has obvious technical effect, and has substantive characteristics and progress compared with the prior art.
The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, but all the insubstantial modifications or changes made within the spirit and scope of the main design of the present invention, which still solve the technical problems consistent with the present invention, should be included in the scope of the present invention.
