The invention discloses a power supply circuit for traction control of a maglev train, and relates to the field of train control. By arranging a traction system power supply circuit, a control circuit can disconnect a circuit between a high-voltage power supply grid and a traction main circuit when receiving a power supply switching instruction, and conduct a circuit between a standby storage battery and the traction main circuit, so that when the high-voltage power supply grid cannot supply power to the traction main circuit, the standby storage battery can supply power to the traction main circuit; the standby storage battery can supply power to the traction main circuit so that the traction main circuit can conduct traction control on the maglev train. Therefore, through power supply switching of the standby storage battery and the high-voltage power supply grid, timely traction power supply of the traction main circuit is guaranteed, the design cost of the track and the maglev train is low, the maintenance difficulty is low, and the traction power supply efficiency of the traction main circuit and the operation efficiency of the maglev train are improved.
本发明公开了一种磁浮列车牵引控制供电电路,涉及列车控制领域。其中通过设置牵引系统供电电路,控制电路能够在接收到供电切换指令时断开高压供电电网和牵引主电路之间的电路,并导通备用蓄电池和牵引主电路之间的电路,以在高压供电电网在无法为牵引主电路供电时,备用蓄电池可以为牵引主电路供电以使牵引主电路对磁浮列车进行牵引控制。可见,本申请中通过备用蓄电池和高压供电电网的供电切换,不仅保证了对牵引主电路的及时牵引供电,轨道及磁浮列车的设计成本也较小,检修难度也较低,提高了对牵引主电路的牵引供电效率以及磁浮列车的运行效率。
