The maglev train comprises the auxiliary power supply system. The maglev rail comprises a power supply rail arranged on the ground, the rated voltage of the power supply rail is 500 volts of direct current, the fluctuation range of the power supply voltage of the power supply rail is 450 volts to520 volts of direct current, and the power supply rail is used for supplying power to the maglev train. According to the embodiment of the invention, the technical problems of heavy weight and loud noise of an auxiliary power supply system and a maglev train are solved.

Description

Technical field [0001] This application relates to the technical field of electric locomotives, in particular to an auxiliary power supply system, a maglev train and a maglev track. Background technique [0002] The maglev train includes a plurality of train units connected in a row, and each of the train units includes an auxiliary power supply system. The auxiliary power supply system directs the electricity of the power supply rail to the train bus through the dynamic contact between the current receiver and the power supply rail. All electrical equipment on the train provides power. Electrical equipment includes suspension systems, air conditioning systems, brake air compressors, train control systems, lighting systems, speed measurement and positioning systems, etc. [0003] The rated voltage of the power rail of the existing medium and low-speed maglev trains (such as Beijing S1 Line and Changsha Airport Line) is DC1500V, and the auxiliary inverter converts DC1500V into AC380...
