摘要： A bifilar winding system for the manufacture of poloidal field superconducting magnets for nuclear fusion includes two superconducting coil winding production lines which are symmetrically arranged, a dropping fixture, a rotary platform and a winding mold, and an automatic control system. Each of the two winding production lines includes a conductor unwinding device, a straightener, an ultrasonic cleaning machine, a sandblasting and cleaning machine, a bending machine, an inter-turn insulation taping machine. During the winding of a coil, a superconducting conductor is unwound by the conductor unwinding device under the control of the automatic control system, then straightened, ultrasonically cleaned, sandblasted and cleaned, and bent into a desired radius, then wrapped with multiple layers of insulating tape by the inter-turn insulation taping machine, and finally fixed, by the dropping fixture, precisely on the rotary platform at a correct position within a profile of the winding mold.

摘要： Disclosed is an insulation treatment method for a helium inlet pipe of a superconducting magnet. The superconducting magnet has a structure with varying T-shaped cross section. The irregular parts of the magnet are filled with G10 to reduce the difficulty in the insulation treatment caused by the irregular shape. Moreover, a skirt-shaped insulating material is provided around the metal conduit to overcome the reduction in the insulation electrical performance caused by the defects in the insulation treatment for such irregular parts. The application designs a sample structure for insulation treatment, and can wrap the superconducting magnet having the T-shaped varying cross-section with insulating materials before vacuum pressure impregnation, meeting special requirements of high-voltage insulation treatment for the superconducting magnet with a complex structure under low temperature and vacuum environment.

摘要： A superconducting magnet for eddy-current braking for a high-speed train. The superconducting magnet is fixed at a bottom of a bogie of the high-speed train through a connecting mechanism, and an air gap is formed between the superconducting magnet and a top of a guide rail below the bogie. The superconducting magnet after being excited generates an eddy-current effect with the guide rail of the high-speed train, so as to generate a braking force opposite to a traveling direction of the train, thereby braking the high-speed train. A liquid-level meter is provided on the superconducting magnet to detect a position of a cooling agent liquid level in real time. The superconducting magnet withstands vibration impact through elastic tie rod assemblies when the high-speed train is under operation, showing good adaptability.

摘要： A deposition system for winding of a large-scale superconducting magnet coil. First and second conductor supports withstand the weight of a bent conductor and allow the conductor to be lowered down in spiral and be placed smoothly onto a rotary table. The rotary table bears the weight of coils, rotates according to a contour of the coil and forwarding speed of the conductor, and tracks the winding trajectory of the coil accurately, which avoids the extra stress induced onto the conductor. The conductor placed on the rotary table is reliably clamped by clamping fixtures and adjustable rod to ensure the conductors to be placed on correct radial and toroidal positions. After treated by the deposition system, the conductor is placed to a corresponding position on the rotary table smoothly and accurately to achieve a high-precision contour control of the coil.
