The invention provides a superconductive magnetic suspension supporting arrangement, and six support modules (10) are symmetrically distributed on a reference axis of orthogonal coordinate system whose original point is the center of a rotor chamber (8). A heating power supply (18) is powered on, and a superconductive switch (16) is disconnected, and a superconductive power supply (19) is used for excitation of a superconducting coil (11). A magnetic field generated by the superconducting coil (11) enters from a middle aperture of the superconducting coil (11) to a middle aperture of the superconductive shaping block (12), and then returns from a gap from the superconductive shaping block (12) and the superconducting ring (13) as well as the lower part of the superconducting coil (11) to the middle aperture of the superconducting coil (11) for forming a closed magnetic circuit. The superconductive rotor (9) is suspended by a magnetic repulsion generated by the superconducting coil (11). After excitation of the superconducting coil (11), the heating power supply (18) is closed and the superconductive switch (16) is connected, and then the superconductive power supply (19) is disconnected, and the current of the superconducting coil (11) can provide a stable suspension magnetic field for the superconductive rotor (9).
Description
Technical field [0001] The invention relates to a superconducting magnetic suspension supporting device. Background technique [0002] With the development of low-temperature technology and the discovery of new superconducting materials, superconducting technology has been widely used. Superconducting instruments based on various characteristics of superconductors play an important role in the economic field, national defense construction and scientific exploration.
