Track for high-temperature super-conductivity magnetic levitation transport system

Abstract

The invention relates to a track for a high-temperature super-conductivity magnetic levitation transport system. The track is symmetrically distributed with a permanent magnet (1) and a poly-magneticpole (2) at two sides of a datum line (L); the bend part of the track is transversely added with 1-5 columns of auxiliary permanent magnets (1') at the outer side of the datum line (L); when the magnetic levitation transport system makes a turn, the track can produce an enough guide restoring force directing towards the inner side for the magnetic levitation transport system so as to prevent the magnetic levitation transport system from being eccentric and escaping from the track and to guarantee the safe and reliable operation of the magnetic levitation transport system; besides, the track for a high-temperature super-conductivity magnetic levitation transport system has less investment and low cost. Compared with the existing translational symmetric track, the track for a high-temperature super-conductivity magnetic levitation transport system has good compatibility and provides convenience to the reconstruction and upgrading of the existing track.

Description

technical field [0001] The invention relates to a high-temperature superconducting magnetic suspension transportation system, in particular to a track of the high-temperature superconducting magnetic suspension transportation system. Background technique [0002] Commonly used high-temperature superconducting materials are rare earth REBaCuO superconducting bulk materials such as yttrium barium copper oxide superconductor (YBaCuO) or gadolinium oxide superconductor (GdBaCuO). The unique magnetic flux pinning ability of these superconducting bulk materials in the superconducting mixed state is used to achieve self-stabilization, no input energy, and a suspension state in a continuous stable interval. This unique and novel self-stabilizing suspension system has relatively simple realization conditions and is very suitable for large-scale engineering applications. Therefore, more than 20 years since the discovery of high-temperature superconducting materials, experimental demo...

Problems solved by technology

[0006] However, when the existing high-temperature superconducting maglev transportation system passes a curve, the vehicle body is always subjected to the centrifugal force directed to the outside of the curve, so that the vehicle body always produces a large deviation to the outside when the curve is turned, and deviates from the reference point. If the speed of the vehicle is too high or the curve is too sharp or other accidental factors also produce the effect of lateral deviation, the restoring force of the magnetic levitation track will not be enough to offset the lateral deviation, resulting in serious accidents such as derailment

[0007] The outer deviation of the car body at the curve will continue to the next straight line. If the magnetic field strength is not enough, it will not be able to return to the baseline and run, which will also make the maglev transportation system prone to eccentricity and derailment.

[0008] If the overall magnetic field strength of the track is increased, although it can ensure that the train does not deviate from the outer side of the curve with a large amount of deviation, the inner magnetic field strength is also greatly increased, resulting in waste and increased costs.
