Description
Technical Field
[0001] The utility model relates to the technical field of rail vehicles, in particular to a suspension electromagnet for a maglev train which is convenient for installation. Background Technique
[0002] The maglev transportation system uses electromagnetic force to achieve non-contact suspension and guidance between the train and the track, and uses the electromagnetic force generated by a linear motor to drive the train. The suspension electromagnets are continuously arranged along the length direction of the train. Each vehicle has 4 suspension frames, each suspension frame has 4 suspension frames, and there are 8 suspension frames on each side of each vehicle. The suspension electromagnets are arranged between two adjacent suspension frames.
[0003] The electromagnet is installed on the base of the maglev system. During the processes of assembling, detecting, painting, testing, etc. of the suspension electromagnet, it is necessary to frequently turn it over. During the turning-over process, it is easy to damage the insulating surface of the coil, affecting the insulating quality of the electromagnet. If a crane is used to lift the electromagnet and turn it over in a suspended state, the operation is relatively complex, the efficiency is low, and there is also a risk that the electromagnet will fall to the ground during the turning-over process;
[0004] And in hot weather, the internal temperature of the electromagnet rises during operation, which will cause the internal insulation of the coil to age faster, the performance to decrease, and even inter-turn breakdown and short-circuit phenomena to occur. Moreover, thermal cracks are easily generated on the surface of the coil, which will greatly shorten the service life of the electromagnet;
[0005] Therefore, the present application provides a suspension electromagnet for a maglev train which is convenient for installation to meet the requirements. Content of the Utility Model
