The invention discloses a superconducting magnet low-temperature system for a high-temperature superconducting maglev train, which adopts an eccentric structure and comprises an inner Dewar (2), a cold shield (5), an outer Dewar (6), a main supporting column (3) and an auxiliary supporting column (4), wherein the cold shield (5) is sleeved outside the inner Dewar (2), and a gap is formed between the outer side wall of the inner Dewar (2) and the inner side wall of the cold shield (5); the outer Dewar (6) is sleeved outside the cold shield (5), and a gap is formed between the outer side wall of the cold shield (5) and the inner side wall of the outer Dewar (6); and the main supporting column (3) and the auxiliary supporting column (4) are installed between the inner Dewar (2) and the outer Dewar (6) and located on the outer side of the inner Dewar (2) and the inner side of the outer Dewar (6). The main supporting column (3) is installed in the center of the superconducting coil, the auxiliary supporting columns (4) are installed on the periphery of the superconducting coil, one ends of the main supporting column (3) and the auxiliary supporting columns (4) are connected with the inner Dewar (2), the other ends are connected with the outer Dewar (6), and the main supporting column (3) and the auxiliary supporting columns (4) are used for limiting vibration of the inner Dewar, the cold shield and the outer Dewar.
