Abstract

The invention provides a long stator structure for a magnetically levitated train and a method for improving the current-carrying capacity of a long stator cable. The long stator structure comprises astator core, a grounding cable and a long stator cable, wherein the grounding cable is arranged parallel to the stator core, the long stator cable is wound to form a three-phase motor winding and provided w ith an embedded part embedded in the stator core, a grounding sleeve is connected between the embedded part and the grounding cable, the grounding cable is in the shape of a hollow tube, the tube cavity of the grounding cable serves as a cooling fluid channel, the tube wall of the grounding cable is provided with spray holes. The grounding cable adopts a hollow tube and serves as a grounding wire and a cooling liquid channel so as to realize the spray of a cooling fluid. The long stator structure is easy to implement and low in cost, and does not affect the line utilization efficiency.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation rails, in particular to a long stator structure for a magnetic levitation train and a method for increasing the ampacity of long stator cables. Background technique [0002] Maglev rail transit technology is based on the principle of long stator linear motors. The train is the rotor, propelled in a straight line by the electromagnetic field of the long stator. Such as figure 1 As shown, the long stator is composed of a stator core 4 and a three-phase motor winding. The three-phase motor winding is wound with a long stator cable 1 and installed under both sides of the guide rail. The grounding system of the long stator cable is composed of cable shielding, outer sheath, grounding sleeve 3 and grounding cable 2. The grounding sleeve 3 is T-shaped, one arm is connected to the outer sheath of the long stator cable 1 , and the other arm is connected to the grounding cable 2 . [0003] L...
