Problems solved by technology

[0005] The main problem of the working grounding method of the suspension frame of medium and low-speed suspension trains is that the large noise grounding current carried by the suspension frame will directly interfere with the position of the car body, thereby indirectly interfering with the weak current equipment on the vehicle, causing occasional abnormal operation of the communication of the weak current equipment. endanger the safe operation of the vehicle

Abstract

The invention provides a medium-low-speed magnetic-levitation train levitation frame work grounding structure, which comprises copper busbars, wherein the copper busbars are arranged at the two sides of a train body and are connected with a grounding wire of a fixed slide table; in addition, the copper busbars are connected with a negative electrode of a power supply rail. By using the technical scheme, the left and right separated grounding strategy of a longitudinal beam and the fixed slide table is used; in addition, the grounding points of levitation frames are directly connected with the negative electrode of the power supply rail through the copper busbars; the interference of the levitation frames on the grounding point positions of the train body in the work process can be avoided, so that the influence on the grounding of vehicle-mounted weak current equipment is indirectly avoided. The mutual redundancy is realized; the work grounding security of the five levitation frames is effectively improved; the coupling interference of the grounding of each levitation frame is eliminated.

Description

technical field [0001] The invention belongs to the technical field of maglev trains, and in particular relates to a working grounding structure for a suspension frame of a medium-low speed maglev train. Background technique [0002] The suspension frame structure of medium and low-speed maglev trains is quite special, which is different from the bogies of general rail locomotives. The unilateral short stator linear induction motor of the maglev train is installed under the longitudinal beam between the support arms on the same side as the track through fixing bolts (just above the conductive aluminum plate of the F rail), and the levitation electromagnet is installed under the support arm and between the longitudinal beams. Connected with double-sheet beams for mechanical decoupling. The support arms, beams and beams are the main components of the suspension frame. When the maglev train is levitating, the mechanical vibration of the suspension frame is significant. At the...
