Problems solved by technology

The tension error detected by this method is relatively large, and the tension control accuracy is not high, which affects the tightness of the inter-turn bonding of the magnet coil
[0005] The mainstream constant tension control winding equipment on the market is mainly used to control the winding of magnet coils with regular shapes (such as circular, with a fixed radius of one rotation), which cannot meet the racetrack type (the radius of one rotation changes greatly) The demand for coil winding of magnets with special shapes

Embodiment 2

[0039] The following uses the racetrack-type superconducting magnet coil winding control method as an embodiment, and in combination with the attached image 3 , the technical solution of the present invention will be further specifically described. Due to the particularity of the superconducting wire, in order to improve the success rate of superconducting magnet coil winding, it is necessary to control the wire tension and coil bonding tightness during the superconducting coil winding process.

[0040] Wire tension is caused by the deformation of the wire caused by the speed difference between unwinding and rewinding during coil winding. According to Hooke's law, the tension is:

[0041]

[0042] In the formula, V 1 is the unwinding speed, V 2 is the winding speed, K T is the elastic coefficient of the wire.

[0043] According to formula (1), it can be known that to maintain the unwinding speed V 1 Constant, by adjusting the winding speed V 2 Tension control can be...

Abstract

The invention discloses an irregular superconducting magnet coil winding control device. The device comprises a control system, and a winding and unwinding system, a detection system, a layer changingmobile platform, a wire pressing device and a human-computer interface which are connected with the control system. The invention further discloses a control method thereof. By keeping the differencebetween the wire winding speed and the wire unwinding speed relatively constant in the coil winding process and keeping the pressure of the wire pressing device acting on the wound wire constant, control over the wire tension and the coil attachment tightness in the superconducting coil winding process is achieved. The special constant tension control method provided by the control device can improve the success rate of winding of coils made of special materials in special shapes.

Description

technical field [0001] The invention relates to a winding control device and method for irregular coils, which are used for winding control of special-shaped constant tension magnet coils, such as the field of winding control of superconducting magnets. Background technique [0002] Superconducting wire is a brittle material with a flat strip structure. It cannot be restored to its original state after being broken, which will affect the performance index of the entire magnet. Therefore, the bending radius of the wire during the winding process of the superconducting magnet coil should not be too small. At the same time, the tension on the wire must be suitable and kept constant during the winding process. Excessive tension may cause damage to the inside of the wire, or even breakage; too small tension will result in a poor fit of the coil, and may also cause accumulation breakage, thereby reducing the overall current and thermal conductivity of the magnet. [0003] As the ...
