Working process of the present utility model and principle are as follows:
Drive tail rod, triaxial force sensor, dowel bar to drive high temperature superconductor coil to move down successively by servomotor, the distance moved under displacement sensor real time record high temperature superconductor coil, stop when arriving superconducting magnet center to high temperature superconductor coil. Liquid nitrogen is injected, until current feed immerses liquid nitrogen completely to T-shaped liquid nitrogen vessel. After high temperature superconductor coil cooling is stable, current feed wiring bar is connected external dc power supply, to the logical direct current of high temperature superconductor coil, produce downward magnetic field. Then to the logical direct current of superconducting magnet, magnetic field upwards is produced. Magnetic field and downward magnetic field interaction upwards produce suspending power, pass to triaxial force sensor through dowel bar, and the force data in three directions that high temperature superconductor coil is subject to by triaxial force sensor gathers in real time. Change superconducting magnet and high temperature superconductor coil lead to into galvanic direction and size, under can measuring different background magnetic field, under different high temperature superconductor coil current conditions, the power that high temperature superconductor coil is subject in three directions, thus complete the magnetic levitation performance test of high temperature superconductor coil.
