The invention relates to a low-noise current receiving system for a medium-low speed maglev train, which includes a ground power supply unit and a lateral current receiver. The ground power supply unit includes a power supply contact line laid under the maglev guide rail along the side of the track beam. The described The power receiving surface of the lateral current collector is arranged as an arcuate power receiving structure, and the arcuate power receiving structure is in sliding contact with the power supply contact line to receive current. Compared with the prior art, the present invention can reduce the occurrence probability and noise level of impact noise during the current receiving process of the maglev train, reduce the loss of the current collector, improve the reliability and comfort of the system, and reduce the system maintenance cost.
Description
Technical field [0001] The present invention relates to the technical field of rail transit vehicles, in particular, relating to a low noise traffic flow system for a medium and low speed magnetic flies. Background technique [0002] Maglev trains are major technological innovations in the field of transportation. The maglev train achieves no contactless suspension and orientation between the train and the track by electromagnetic force, and then operates with the electromagnetic traction train generated by the linear motor. The medium and low-speed maglev train as a maglev train has the advantages of low noise, high comfort, and good environmental performance, which can meet the urban-wide, suburban and short-distance intercity transportation needs. [0003] The medium and low-speed magnetic suspension train uses a short-fastened sub-induction motor, and the induction motor stator of the train needs to be electrical energy from the ground. At present, the mode of power supply in...
