Embodiment 1

[0032] Example 1 Take PF5 superconducting cable as an example,

[0033] When the superconducting cable is stranded, the strands first pass from the sheave 17 to the first doubling die 91 with an aperture of 38.5 mm, and then pass through the second doubling die 92 with an aperture of 37.5 mm to be closed. The guide cable enters the first roller roller 11 with an aperture of 36.5 mm, the second roller roller 12 has an aperture of 36.3 mm, the third roller roller 13 has an aperture of 36.0 mm, the fourth roller roller 14 has an aperture of 35.8 mm, and the fifth roller The diameter of the roller 15 is 35.6 mm, and the diameter of the sixth roller 16 is 35.4 mm for rolling, so that the outer diameter of the superconducting cable reaches 35.4±0.4 mm. After six rollers for rolling, the surface of the roller is hardened and polished, so that the surface coating of the cable strand will not fall off or be damaged due to the uneven surface of the roller during rolling. After that, the c...

Abstract

The invention discloses a stranded cable outer-diameter control device for a superconducting cable conductor for a nuclear fusion device and a control method, used for solving the problems of the falling-off of superconducting plied yarn coating layer, the breakage of superconducting filaments, and the non-uniform of void ratio existing in twisting, compressing and outer-diameter controling for a superconducting cable. The stranded cable outer-diameter control device comprises a stranding closer, rolling wheel groups, and a shaping-sizing die, wherein rolling wheels are arranged behind the stranding closer, the shaping-sizing die is disposed behind the rolling wheels, and at least six rolling wheel groups are arranged; each rolling wheel group comprises an upper rolling shaft, a lower rolling shaft, an upper rolling wheel, a lower rolling wheel and a bearing, a rolling hole is arranged between the upper rolling wheel and the lower rolling wheel, the rolling holes of the rolling wheel groups are located on one centre line, and the apertures of the rolling holes of the rolling wheel groups are orderly reduced from the stranding closer end to the shaping-sizing die end; and the rolling shafts in the adjacent rolling wheel groups are vertically arranged. According to the stranded cable outer-diameter control device for the superconducting cable conductor for the nuclear fusion device and the control method, disclosed by the invention, the outer diameter of the superconducting cable is constant, and the twisted superconducting cable can reach the requirements of the technical specifications of the superconducting cable.

Description

Technical field [0001] The invention relates to the field of superconducting wire stranded cables, in particular to a device and method for controlling the outer diameter of a superconducting cable conductor stranded cable for a nuclear fusion device. Background technique [0002] Superconducting cable (CICC) tube-mounted cable conductor is a multi-level cable. The first-level sub-cable of the conductor is composed of several copper wires and several superconducting wires twisted at a certain twisting pitch, and then several sub-cables The cable unit is then twisted according to a certain twisting pitch to form a secondary sub-cable, and in the same way, a third and fourth-level sub-cable is formed, and finally a five-level polar cable is twisted. After the superconducting cable is twisted, there are 1154 superconducting strands, each of which has a diameter of 0.73±0.003mm, and is composed of many ultra-fine superconducting wires. Because the outer diameter of each level of cab...
