Abstract

The invention discloses a bifilar winding system for manufacture of nuclear fusion polar field superconducting magnets, comprising two totally symmetric superconducting coil winding production lines,as well as a drop-molding tool, a rotary platform and a winding mold, and an automatic control system, wherein each winding production line is respectively composed of conductor discharging equipment,a straightening machine, an ultrasonic cleaning machine, a sand blasting cleaning machine, a bending forming machine, an inter-turn insulation tape wrapping machine, etc.; in the coil winding process, the automatic control system discharges the superconducting conductor from the conductor discharging device, and then bends the conductor into a required radius after straightening, ultrasonic cleaning, sand blasting and cleaning, then completes the wrapping of the multi-layer insulating tape by the inter-turn insulating tape wrapping machine, and finally precisely fixes the conductor at the correct position in the contour of the mold on the rotary platform by the drop tooling until the bifilar winding coil is wound. Finally, the invention meets the requirements such as high-precision size and inter-turn insulation performance for manufacture of nuclear fusion polar field superconducting magnets.

Description

technical field [0001] The invention relates to the field of manufacturing thermonuclear fusion superconducting magnets, in particular to a double-wire parallel winding system for manufacturing nuclear fusion poloidal field superconducting magnets. Background technique [0002] Thermonuclear fusion will provide mankind with inexhaustible clean energy, and the International Thermonuclear Test Reactor (ITER) program will be built in the next ten years. The superconducting magnet provides the required magnetic field for the tokmak device to achieve the purpose of controlling and confining the high-temperature plasma. [0003] The poloidal field magnet is one of the main magnets of the superconducting magnet of the Tokmak device, which is used to control the shape of the plasma and stabilize the shape of the plasma. Due to the limitation of conductor manufacturing and production, the length of a single superconducting conductor is usually not greater than 1km. In order to reali...

Problems solved by technology

At present, the double-wire parallel winding technology for large-scale poloidal field superconducting magnets is still blank in China, and it meets the requirements of high-precision shape and position, surface cleanliness, and inter-turn insulation automatic wrapping after large-scale superconducting magnet coils are wound. The production line design experience in China is limited, so a dual-wire parallel winding system technology for the manufacture of nuclear fusion poloidal field superconducting magnets provides a mature and feasible solution to fill the above gap
