Abstract

The invention relates to the technical field of high-speed maglev traffic, and discloses a suspension propelling and guiding integrated module and a maglev track system. The module comprises an upper coil, an upper coil framework, a lower coil, a lower coil framework, a binding structure, a high-voltage connector and a shell, wherein the upper coil, the upper coil framework, the lower coil, the lower coil framework and the binding structure are all arranged in the shell, and the upper coil and the lower coil are correspondingly arranged on the upper coil framework and the lower coil framework respectively and bound through the binding structure. Two upper coil outgoing lines of the upper coil are led out from the innermost layer of the upper coil through a first outgoing line groove of the upper coil framework and are vertically led out to the bottom connecting part through a second outgoing line groove in the upper surface of the lower coil framework; the two lower coil outgoing lines of the lower coil are led out from the outer side of the lower coil to the bottom connecting position and are connected with the two upper coil outgoing lines respectively to form two connecting points, and each connecting point is connected with one high-voltage connector. Therefore, the structural strength requirement of the integrated coil can be met, and the structure is more reliable.

Description

technical field [0001] The invention relates to the technical field of high-speed maglev transportation, in particular to a levitation propulsion and guidance integrated module and a maglev track system. Background technique [0002] The superconducting magnetic levitation propulsion system composed of upper and lower asymmetric 8-shaped suspension coils and superconducting magnets has the advantages of high floating resistance ratio, self-stabilization of suspension guidance, large suspension gap, and small vibration. Three-phase alternating current is input, so that the upper and lower coils form a pair of parallel synchronous linear motors with respect to the superconducting magnets, so that a set of 8-shaped coils can be used at the same time to have the function of levitation propulsion and guidance, eliminating the need for the original independent linear synchronous motor stator, which can be greatly improved. Reducing the manufacturing cost of the ground module and t...

Problems solved by technology

[0007]Because the mechanical strength of the reinforced resin and the reinforced dielectric strength itself are contradictory, the mechanical strength needs to be added to the resin to add auxiliary reinforcing materials such as fibers, but the resin material will be uneven, It reduces the insulation performance and needs to be compensated at the cost of increasing the thickness, which further increases the volume of the module and the amount of materials used. At the same time, because the epoxy resin is a brittle material, the alternating load on the conductor is directly applied to the epoxy resin. Greatly reduces the fatigue life of the resin

[0008]Because in the prior art in Japan, the lead wires of the upper coil are set to lead from both sides of the lower coil, this design causes the actual conductor of the lower coil to have two more vertical sides and One horizontal side, and the current direction of the extra conductor side is opposite to the current direction of the lower coil itself. In addition, the lead-out line occupies an additional width of the lower coil, so that the width of the center line of the lower coil is smaller than the width of the upper coil under the condition of the same outline size , which weakens the suspension propulsion guidance performance of the lower coil

[0009] In the prior art, three high-voltage connectors including the outlet point of the hinge line and the entry and exit points of the propulsion current are integrated into one module, and the hinge connector needs to be connected with a propulsion current The connectors are connected in parallel inside the module, which increases the number of parallel connection points in the module and the contact resistance caused by parallel connection, and also makes it difficult to connect the modules in a compact space.

In addition, an extra high-voltage connector increases the vertical length of the module, making it less versatile in terms of installation space than the original 8-shaped suspension coil module that was only used for suspension guidance
