摘要： Disclosed is a circulating device for cooling and heating superconducting magnet components at controllable rate, including a liquid nitrogen tank and a vacuum container. A container for accommodating the superconducting magnet component is provided at an upper end of an interior of the vacuum container. First and second pipelines join and then connect to a top of the liquid nitrogen tank through a coiled pipe. A third pipeline and a first branch of a fourth pipeline join and then connect to an inlet of an electric heater. A PID closed loop for temperature control is provided at the electric heater. A main pipeline of the outlet pipeline of the electric heater is connected to an inlet of the container. A second branch of the fourth pipeline, an outlet pipeline of the container and a branch pipeline of the outlet pipeline of the electric heater communicate with atmosphere.

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.

摘要： Disclosed is a bifilar winding system for the manufacture of poloidal field superconducting magnets for nuclear fusion, including 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.
