Description

Device and method for manufacturing high-temperature superconducting bunched cable suitable for internally-sealed optical fiber

Technical Field

The invention relates to the technical field of superconducting cables, in particular to a device and a method for manufacturing a high-temperature superconducting bunched cable suitable for an internally-sealed optical fiber.

Background

The high-temperature superconducting bunched cable internally sealed with the optical fiber not only has high current carrying capacity and a complete transposition structure of the conventional high-temperature superconducting bunched cable, but also can monitor the temperature of the whole high-temperature superconducting bunched cable through the internally sealed optical fiber, so that the position of a hot spot is positioned, and the running safety of the high-temperature superconducting cable is improved. The high-temperature superconducting cable places optical fibers by slotting the copper core framework, and limits the positions of the optical fibers by layer-by-layer wrapping of the strip materials. The innovative structure is expected to overcome the problem of difficult quench detection of the long-distance high-temperature superconducting cable, so that the high-temperature superconducting tape really leaves a laboratory and is applied to engineering.

At present, two units at home and abroad describe and prepare concepts and samples for combining optical fibers and high-temperature superconducting bundled cables. The search shows that: the J Schwartz team in D.C. van der Laan et al,

The structure of a high-temperature superconducting CORC cable with an internally sealed optical fiber and a simple preparation method thereof are described in wire via integrated optical fibers, vol.34, No.3, 2021 and art.035026.

In Bin Chen et al, Distributed optical fiber sensor for the introduction of magnetic zone propagation and hot spot location in REBCO cables, Fusion Eng. Des., vol.156, 2020, Art.no.111569, an optical fiber is placed on a straight groove on the surface of a copper core frame, and another optical fiber is placed on the surface of a bundled cable, and a method of heating to cause quench is adopted, so that the positioning of the hot spot position and the calculation of the quench propagation velocity are successfully realized.

The above documents prove that the high-temperature superconducting bundled cable with the internally sealed optical fiber can realize self-monitoring of the temperature of the high-temperature superconducting bundled cable, but a device and a method for manufacturing the high-temperature superconducting bundled cable with the internally sealed optical fiber are not explicitly described, so that a device and a method for manufacturing the high-temperature superconducting bundled cable with the internally sealed optical fiber are needed to be designed, which can realize effective positioning of the optical fiber, can ensure that the optical fiber is smoothly placed in a groove of a copper core of the cable, and can ensure that an external superconducting tape is uniformly wound.

However, this patent document does not disclose a device and a method for manufacturing a high-temperature superconducting bundled cable.
