The invention discloses a high-temperature superconducting magnetic levitation system with high magnetic levitation performance. The high-temperature superconducting magnetic levitation system comprises a cold source, a superconductor array and a permanent magnet track, the superconductor array and the cold source are arranged over the permanent magnet track, the superconductor array is composed of a plurality of superconductors, seed crystal points of the superconductors face the permanent magnet track, the cold source is connected with the superconductors and cools the superconductors, and the permanent magnet track provides an applied external magnetic field; and the superconductors are symmetrically arranged in an offset mode along the central axis of the permanent magnet track, and the offset distance is 0-5 mm. In a single-magnetic-pole or multi-magnetic-pole permanent magnet track, the superconductors are symmetrically arranged in an offset mode along the single-magnetic-pole axis or the symmetrically-distributed multi-magnetic-pole axis, guiding instability in the system pressing process can be restrained, and when a proper offset distance is selected, the influence of offset on suspension force attenuation can be restrained; therefore, the system has higher suspension performance while giving consideration to the guiding stability.

    本发明公开一种高磁浮性能的高温超导磁浮系统,其包括冷源、超导体排列和永磁轨道;超导体排列和冷源设置在永磁轨道上方,超导体排列由多个超导体组成,超导体的籽晶点面向永磁轨道,冷源连接超导体并对超导体进行冷却,永磁轨道提供应用外磁场;超导体沿永磁轨道的中心轴线对称偏置排列,且偏置距离为0~5mm。本发明在单磁极或多磁极永磁轨道中,使超导体沿单磁极轴线或对称分布的多磁极轴线进行对称偏置排列,可以抑制系统下压过程中的导向不稳定性,当选择合适的偏置距离时,可以抑制偏置对悬浮力衰减的影响,从而使系统兼顾导向稳定性的同时,具有更高的悬浮性能。
