Description
Technical Field
The invention relates to an internally-sealed optical fiber superconducting tape, in particular to an internally-sealed optical fiber superconducting tape optical fiber outgoing line protection device and a processing method.
Background
The inner-sealed optical fiber superconducting tape is a composite superconducting tape which is proposed in recent years. The superconducting tape can realize the superconducting quench self-detection function through the internally sealed optical fiber and the externally connected optical fiber temperature sensing demodulation equipment on the premise of not influencing the electrical performance and the structure of the whole wire. The superconducting strip plays a great role in promoting the practical application of the future superconducting industry and the safe operation and control of corresponding power equipment.
Currently, no practical engineering application paradigm for the encapsulated fiber superconducting tapes has emerged worldwide. Numerous documents show that such tapes are currently still in the laboratory research phase. The detailed structure of the internally-enclosed optical fiber superconducting tape has been presented in some documents.
Chinese patent application No.: CN201410375117.8, patent name: the superconducting tape of the inner-sealed optical fiber and the preparation method thereof disclose a superconducting tape of the inner-sealed optical fiber, which comprises the following steps: the measuring device comprises an upper protective layer, a lower protective layer, a superconducting tape layer and a measuring optical fiber, wherein the superconducting tape layer and the measuring optical fiber are packaged between the upper protective layer and the lower protective layer, and the measuring optical fiber is arranged in the extension direction. The measuring optical fiber is continuously packaged between the upper protective layer and the lower protective layer by adopting a plurality of long optical fibers, or a plurality of sections of optical fibers are discontinuously packaged between the upper protective layer and the lower protective layer. Meanwhile, a preparation method and a preparation device of the superconducting tape are also provided. According to the description of this patent, it is indeed possible to achieve long-distance measurements of the temperature of superconducting tapes without destroying the overall structure of the tape.
Furthermore, "Self-monitoring" in the document f.scrorti et al
The same encapsulated fiber superconducting tape structure is also described in (RE) Ba2Cu3O7-x conductor via integrated optical fibers, "Supercontrolled. Sci. technol., vol.30, No.11,2017, Art. No.114002. In this document, the optical fiber used is polyimide coated and has a diameter of about 100 microns.
Through various searches, it can be easily found that the measuring optical fiber used in the inner-sealed optical fiber superconducting tape is very fine. Optical fibers are generally relatively resistant to axial tension, but are susceptible to breakage when subjected to radial stress. In practical applications, it has been found that the optical fibers in such tapes are highly susceptible to breakage after being drawn from the superconducting tapes. The reason for this is that the superconducting tape is encapsulated and protected by the upper and lower metal protective layers, and the entire thickness of the superconducting tape is very thin. This results in the edges of the side edges or the bottom edge of the superconducting tape being very sharp, and thus the optical fiber is easily cut by the edges of the superconducting tape. Therefore, the problem of optical fiber outgoing line protection of the inner-sealed optical fiber superconducting tape needs to be solved urgently.
The key points for solving the problem are mainly divided into the following aspects: 1. the current carrying capacity of the inner-sealed optical fiber superconducting tape cannot be influenced, namely the critical current of the superconducting tape cannot be changed; 2. the optical signal transmission of the optical fiber cannot be influenced; 3. when in site construction, the optical fiber is not easy to break.
Through search, no description or report of similar technologies of the invention is found at present, and similar data at home and abroad is not collected.
