Superconducting magnet coil with wedge-shaped section for reducing waviness and conductor winding and forming method

Abstract

The invention discloses a superconducting magnet coil with a wedge-shaped section for reducing waviness and a conductor winding and forming method. The superconducting magnet coil with a wedge-shaped section for reducing waviness comprises a mould which comprises a plurality of forming blocks and a central supporting column. Each forming block comprises two arc-shaped blocks in butt joint at one ends. An assembling hole is arranged in the inner wall of each arc-shaped block. A plurality of positioning blocks are respectively arranged on both sides of the central supporting column form top to bottom. Each positioning block is separated from the adjacent positioning blocks up and down. The pair of arc-shaped blocks of each forming block is respectively locked on the central supporting column from both sides of the central supporting column, and a wire is continuously winded and formed on the mould around the central supporting column along the gap between adjacent forming blocks. According to the superconducting magnet coil with a wedge-shaped section for reducing waviness and the conductor winding and forming method provided by the invention, under the premise of guaranteeing the assembling space and reducing the cost, the outermost waviness in the circumference of a large ring is effectively reduced so that the waviness in a rim area of a plasma in the center of the magnet coil is further reduced, the stable operation of the plasma is ensured, and the fabrication design and process of the coil conductor are reasonable and convenient to realize.

Description

technical field [0001] The invention relates to the field of superconducting tokamak devices, in particular to a wedge-shaped cross-section superconducting magnet coil and a conductor winding forming method for reducing waviness. Background technique [0002] Magnetic confinement is to use the characteristic that a strong magnetic field can well confine charged particles, construct a special magnetic container, and build a fusion reactor, in which the fusion material is heated to a high temperature of hundreds of millions of degrees Celsius to achieve fusion reaction. At present, with the establishment of Tokamak devices such as ITER, EAST, and KSTAR, the research on fusion energy has made significant progress. Magnetic confinement studies of the tokmak type are considered the most promising for commercial energy use ahead of other avenues for controlled thermonuclear fusion. [0003] Tokmak is a ring-shaped strong magnetic field device. The magnetic field configuratio...

However, considering the realization of deuterium-tritium reaction in the future fusion reactor, the size of the window used for disassembly and maintenance of internal components will be very large. If we continue to increase the longitudinal field magnet coil to a higher density according to the current experience, it will inevitably be larger than the device.
