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： 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 plasma-facing component of a fusion reactor divertor, including an inner target transition support and a dome transition support which are integrated into an inner target-dome transition support. The inner target-dome transition support and an outer horizontal target transition support are each prepared from two materials. The channel connection inside the inner target-dome transition support and the outer horizontal target transition support is realized through an S-shaped flow channel and a collector box. In V-shaped regions of inner and outer targets, a plasma-facing unit is connected to the collector box in the transition support via a bending tube, and is communicated with a coolant flowing through horizontal and vertical targets through an intermediate flow channel in the transition block. A method of preparing the plasma-facing component is further provided.

摘要： The present invention discloses an inter-layer transition forming machine for winding of a large-sized superconducting coil. A vertically movable forming mechanism and a horizontally movable forming mechanism are mounted on a fixing plate. When the winding of a large-sized superconducting coil performs inter-layer transition, an armored superconducting conductor is clamped by wedge clamping mechanisms with right- and left-handed threads on the vertically movable forming mechanism and the horizontally movable forming mechanism, and a reference line on the conductor is ensured to be aligned with a reference line on a forming mold. The vertically movable forming mechanism is pressed down, under the drive of a double-acting hydraulic cylinder, in a vertical direction to form inter-layer transition, and the horizontally movable forming mechanism moves in a horizontal direction according to the reduction of the vertically movable forming mechanism.
