Description
Technical Field
The utility model relates to a magnetic suspension traffic technical field, in particular to suspension propulsion coil integrates module.
Background
The superconducting magnetic suspension system composed of the zero magnetic flux coil and the superconducting magnet has the advantages of high floating resistance ratio, self-stability of suspension guidance, large suspension gap and the like. The superconducting linear synchronous motor system composed of the hollow propulsion coil and the superconducting magnet has the advantages of high power density, small loss, high efficiency and the like, and the linear superconducting magnetic suspension electromagnetic propulsion system formed by combining the hollow propulsion coil and the superconducting magnet has wide application prospects in the aspects of high-speed and ultrahigh-speed rail transit. According to the combination, a large number of zero-magnetic-flux coils and propulsion coils need to be continuously laid on a stator track, the two coils are integrated in the same module to be manufactured and laid, and the module manufacturing cost and the track construction cost can be greatly reduced.
When the 8-shaped closed-loop zero-magnetic-flux coil bearing the suspension guide function and the hollow propelling coil are integrated in the same module, the zero-magnetic-flux coil is a low-voltage coil and bears electromagnetic load with larger amplitude, so that the zero-magnetic-flux coil assembly needs to ensure larger structural strength; the propulsion coil is a high-voltage coil, bears less electromagnetic load, and the propulsion coil assembly needs to ensure better insulation strength. Because high performance insulating materials generally require higher material consistency, the main insulating layer needs to avoid the bonding of different material structures, so it is difficult to adapt to the support of the zero-flux coil component and the propulsion coil component in the module simultaneously with the same structure.
In addition, an electric field is required to be shielded by a conductive grounding layer between the high-voltage propelling coil and the low-voltage zero-flux coil, so that the zero-flux coil is prevented from inducing high voltage. The conductive grounding layer is a laminated structure capable of completely covering the propulsion coil, and is accurately positioned in the epoxy-cast module so as to ensure that the uniformity of the gap between the conductive grounding layer and the propulsion coil is crucial to the insulation performance of the module.
At present, the manufacturing method for integrating the zero-flux coil and the propulsion coil into a module mainly has two schemes of no framework structure and framework structure.
The non-framework structure is characterized in that the propulsion coil, the shielding layer, the zero-magnetic-flux coil and other internal components are sequentially stacked in the mold through the insulating cushion blocks, the non-framework structure is simple in structure and low in cost, the cushion blocks between the zero magnetic flux and the propulsion coil cannot be fixed with the mold at a fixed position, the non-framework structure has the problems of random positions and poor consistency, the structural strength of the zero-magnetic-flux coil part in the non-framework scheme is only provided by resin, the strength is low, and the non-framework structure is difficult to adapt to the larger suspension and guide working conditions in the future.
The framework structure enables the propulsion coil and the zero-flux coil to be wound on the prefabricated framework, the propulsion coil and the zero-flux coil are mutually connected and positioned through the supporting rods between the frameworks, and the structural strength of the zero-flux coil and the propulsion coil is very high. Because the cost of the machined monolithic solid insulating coil framework is high, and the monolithic solid insulating coil framework is made of different materials from resin, the insulating property of the high-voltage propulsion coil can be obviously reduced after pouring, so that the propulsion coil is wrapped by other continuous insulating materials such as mica and the like to serve as main insulation, the structural complexity is increased, and the insulating property of the resin cannot be fully utilized.
The current module that integrates all need install in proper order, fix a position at the mould and correspond the position before pouring each subassembly (including zero magnetic flux coil, propulsion coil, shielding layer and inoxidizing coating) in the module, and the process is complicated and wastes time and energy.
