Embodiment

[0026] like figure 1 As shown, a low-noise current receiving system for medium and low-speed maglev trains includes a ground power supply unit and a side current receiver. The electric surface is set as a bow-shaped power receiving structure, and the bow-shaped power receiving structure is in sliding contact with the power supply contact line to receive current. The power supply contact wire includes multiple power supply contact wires 1 laid in sequence. The power supply contact wire 1 is a copper alloy sliding contact wire. The length of a single power supply contact wire 1 is 1-2 kilometers. The length of a single power supply contact wire 1 in this implementation is Set to 1.5 km.

[0027] The power supply contact line 1 is fixed on the first insulator 3 by the fixing groove 2, and the first insulator 3 is installed on the side of the track beam under the magnetic levitation guide rail through the fixing mechanism 4.

[0028] like figure 2 As shown, the bow-shaped powe...

Abstract

The invention relates to a low-noise current collecting system for a medium-and low-speed maglev train. The system comprises a ground power supply unit and a lateral current collector. The ground power supply unit comprises a power supply contact line laid below a maglev guide rail and along the lateral side of a rail beam, a current collecting face of the lateral current collector is in an arch current collecting structure, and slide contact current collection between the arch current collecting structure and the power supply contact line is realized. Compared with the prior art, the system has advantages that the noise level and probability of occurrence of impulsive noise in a current collecting process of the maglev train can be lowered, loss of the current collector is reduced, reliability and comfort of the system are improved, and system maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a low-noise current receiving system for a medium-low speed maglev train. Background technique [0002] The maglev train is a major technological innovation in the field of transportation. The maglev train realizes the non-contact suspension and guidance between the train and the track through electromagnetic force, and then uses the electromagnetic force generated by the linear motor to drive the train. As a form of maglev train, medium and low-speed maglev trains have the advantages of low noise, high comfort, and good environmental protection performance, and can meet the transportation needs within the city, between suburbs and short distances between cities. [0003] Medium and low-speed maglev trains are driven by short-stator induction motors, and the induction motor stators installed on the trains need to be powered by the ground. At present, the power sup...
