Problems solved by technology

[0006] Polyimide is not suitable for tape insulation in superconducting energy storage magnets and conduction cooled MRI main magnets due to their very low wettability to epoxy resins and their low thermal conductivity
Because the adhesive layer will prevent the epoxy resin from curing on the high-temperature superconducting tape, and the poorly cured superconducting magnet cannot solve the problem of electromag

Embodiment Construction

[0024] The insulation wrapping device for superconducting tape consists of two parts: mechanical device and numerical control system. As shown in Figure 2, the superconducting tape winding reel is installed on the main shaft of the torque motor 9, and the superconducting tape 7 is fixed on the winding reel on the main shaft of the AC servo motor 2 through a traction belt, controlled by the numerical control system, The insulating tape winding reel 5 rotates around the superconducting tape 7 , and the glass fiber cloth on the insulating tape winding reel 5 is wrapped on the superconducting tape 7 . Adjust the rotation speed of the insulating tape winding reel 5 of the superconducting tape insulation wrapping device and the linear displacement motion speed of the superconducting tape 7 to control the pulling force and the glass fiber cloth on the superconducting tape 7 during the wrapping process. The tension on the surface makes the up and down vibration of the superconducting ...

Abstract

A NC system for a superconducting material insulation covered device comprises a numerical control device, a servo system and a measurement feedback system, wherein, the numerical control device receives information of requirement for superconducting material insulation covered, compiles and sends the information to the CPU of the numerical control device for memorizing and processing, the instructions of location and speed are sent to the servo system through the output device. The servo system, after power amplification and filtering plastic processing, converts the instructions from the numerical control device into the linear displacement and the angular displacement campaign of executive institutions. The measurement feedback system detects the current operation value of an AC servo motor and feedbacks to the numerical control device; wherein, the numerical control device compares the prior operation value with value of orders, and outputs the order that meets the requirement of the setting value to the servo system. The invention can realize superconducting material with lower irreversible strain (for example, the Bi-2223 high-temperature superconducting material with the critical stress of 230 MPa, MgB on the critical stress of 465 MPa2 superconducting material) to safely and accurately cover an insulation material with lower mechanical strength.

Description

technical field [0001] The invention relates to manufacturing equipment for superconducting energy storage magnets and MRI main magnets, in particular to a numerical control system for a superconducting tape insulation wrapping device. Background technique [0002] Usually the manufacturing process of pie-type superconducting magnets includes superconducting strip performance testing, superconducting strip insulation wrapping, wrapping insulation testing, winding of superconducting double cakes, performance testing of superconducting double cakes, superconducting double cakes Assembled into a magnet, the performance test of the magnet and other processes. For superconducting energy storage devices in superconducting power equipment (eg, 1MJ / 0.5MVA superconducting energy storage devices), because they need to be connected to the grid for operation, it is necessary to consider the withstand voltage level between the magnet and the metal Dewar container (eg, 10kV withstand vol...
