Description
Technical Field
The invention relates to the technical field of high-speed magnetic suspension traffic, in particular to an integrated suspension propulsion module.
Background
The superconducting magnetic suspension system composed of the zero-flux suspension coil and the superconducting magnet has the advantages of high floating resistance ratio, self-stability of suspension guidance, large suspension gap and the like, and is combined with the hollow stator linear synchronous motor to be more and more widely applied to high-speed and ultrahigh-speed magnetic suspension trains. However, the method needs huge ground 8-shaped suspension coil stator modules and propulsion coil stator modules, so that the track construction cost is high, the ground coil installation workload is high, the relative position between the suspension coil and the propulsion coil is difficult to accurately adjust, and two ground stator coils need to be integrated together in a proper mode so as to greatly reduce the number of the ground modules and the number of on-line installation times.
The ground module bears the most important suspension propulsion guiding function and needs to have higher installation precision to avoid additional fluctuation caused by suspension force, propulsion force and guiding force of the train. Therefore, the ground module mounting structure needs three degrees of freedom to be adjustable and fixed, and is convenient to detach. In addition, the module mounting structure bears three-degree-of-freedom alternating load on the module, and high firmness and reliability are required.
The scheme of integrating the side wall suspension coil and the propulsion coil into a module is firstly proposed in japan, and the scheme is that the 8-shaped suspension coil and the rectangular propulsion coil are placed in a mould and integrally encapsulated and molded by using epoxy resin, a thin plate material with electric conduction capability is additionally added between the suspension coil and the propulsion coil, and the ground is connected to prevent the propulsion coil from being punctured by high voltage on the suspension coil. The bottom of the formed module is placed on the ground and is directly fixed on the side wall of the concrete by using bolts.
The propulsion coil is mainly a high-voltage coil, and the most important function of the module is insulation protection, so that potting resin is required to contain no impurities as much as possible to ensure the insulation performance, but the 8-shaped suspension coil is mainly a coil bearing strong electromagnetic force, the module is mainly structurally supported, and resin potting doped with fiber materials is required, so that the mode of integrating the two coils in the same module needs pure resin to bear larger load, and the resin is brittle, so that the risk of damage such as cracks, fatigue and the like is easy to occur.
Although large-area conductive plates are laid between the suspension coil and the 8-shaped coil and are grounded, the risk of insulation breakdown of the propulsion coil on the suspension coil is avoided, the plates are large in area and thin, the relative position between the propulsion coil and the propulsion coil in encapsulation is difficult to guarantee, the thickness of insulation of the propulsion coil on the ground is easily inconsistent, and the risk of breakdown of the propulsion coil on the ground conductive plate is caused.
Although the ground module is directly installed on the side wall by using the bolts, the operation is simple, the bolt holes in the module need to be larger than the outer diameter of the bolts due to certain installation errors of nut sleeves embedded in the side wall, the thrust force of the ground module is completely born by the bolt pressing friction force after installation, the fastening bolts are easy to loosen due to the fact that the thrust force is reciprocating alternating load, in addition, the module is only freely placed on the ground, the contact surface of the module and the ground does not have the pre-pressing force, downward pressure generated by the internal suspension coil can be firstly transmitted to the bolt pressing surface and then transmitted to the ground, and the risk of bolt loosening is further increased.

Fig. 1 is a schematic structural diagram of an integrated levitation propulsion module according to an embodiment of the present invention.
Fig. 2 is a schematic diagram illustrating a supporting framework of an integrated levitation propulsion module according to an embodiment of the present invention.
As shown in fig. 1 and 2, the present invention provides an integrated levitation propulsion module, wherein the module comprises: 8-shaped suspension coil 1, supporting framework 2, binding structure 3, propulsion coil component 4, shell 5, wire nose 6, high-voltage connector 7 and low-voltage connector 8, the 8-shaped suspension coil 1, the supporting framework 2, the binding structure 3, the propulsion coil assembly 4, the wire nose 6, the high-voltage connector 7 and the low-voltage connector 8 are all arranged in the shell 5, the upper and lower coils of the 8-shaped suspension coil 1 are respectively wound on the corresponding support frame 2 and bound through the binding structure 3, the upper surface of the supporting framework 2 is provided with a propulsion coil positioning framework 23, the propulsion coil assembly 4 is arranged on the propulsion coil positioning framework 23, the two ends of the propulsion coil assembly 4 are respectively connected with the wire noses 6, each wire nose 6 is connected with the high-voltage connector 7, and the low-voltage connector 8 is connected with the 8-shaped suspension coil 1.
That is, one propulsion coil assembly may correspond to two wire noses, and each wire nose may be connected to one high-voltage connector.
Through above-mentioned technical scheme, can make suspension coil and propulsion coil integrated in same module, satisfy propulsion coil and suspension coil's structural strength requirement completely to greatly reduced intensity and the insulating requirement to the embedment casing, make to integrate suspension propulsion module structural strength and dielectric strength height, and the reliability is high.
The supporting framework 2 can be made of a high-strength composite material, and the shell 5 can be integrally molded by potting and using epoxy resin.
For example, vacuum epoxy potting may be performed to eliminate the presence of air bubbles inside and to provide insulation protection for the wire stubs, high voltage connectors, etc. to which the propulsion coil assembly lead wires are connected. Because the interval between the two outgoing lines is large, the bottom space is large, and therefore enough epoxy resin thickness can be provided for providing insulation protection to the ground for the high-voltage connector.
According to an embodiment of the present invention, an adjusting boss 22 is disposed between the upper surface of the supporting frame 2 and the propulsion coil positioning frame 23, and the adjusting boss 22 is used for adjusting the interval between the 8-shaped levitation coil 1 and the propulsion coil assembly 4.
Therefore, the distance between the propulsion coil and the suspension coil can be adjusted by adjusting the boss.
According to an embodiment of the present invention, the module further comprises a fiberglass mesh cloth disposed between the housing 5 and the lower surface of the support frame 2.
In other words, the support skeleton provided with the levitation coils and the propulsion coils may be provided on a fiberglass mesh cloth.
Thus, in the case of integrally potting each component using epoxy resin, when the epoxy resin is cured, the glass fiber mesh cloth of the lower surface of the support frame is integrally formed with the epoxy resin (i.e., a high-strength resin fiber composite material is formed) for resisting external impact in common. In addition, the glass fiber of ligature suspension coil upper portion horizontal limit forms high strength resin fiber composite with epoxy equally, has increased the structural strength of module.
According to an embodiment of the invention, a prefabricated groove 21 is arranged above the supporting framework 2, and the upper transverse edge of the upper coil of the 8-shaped suspension coil 1 is bound on the prefabricated groove 21 through the binding structure 3.
The lashing structure 3 may be, for example, a glass wire.
According to an embodiment of the present invention, the number of the 8-shaped suspension coils 1 is two, the number of the support frames 2 is four, the propulsion coil positioning frames 23 are quarter cylinders (for example, quarter circular bosses), and the propulsion coil positioning frames 23 on the four support frames 2 are cooperatively used for arranging the propulsion coil assemblies 4.
That is, an 8-shaped suspension coil corresponds to two support skeletons, that is, an upper coil corresponds to one support skeleton, and a lower coil corresponds to one support skeleton. Four on the support skeleton propulsion coil location skeleton can form a complete propulsion coil location skeleton after the suspension coil location to can set up and fix a position the propulsion coil subassembly.
As can be seen from fig. 2, each independent support frame is used for winding the suspension coil, so that the coil precision is ensured, and the propulsion coil positioning frames on the support frames form complete propulsion coil positioning frames after being positioned in the mold. Because the supporting framework is manufactured by machining, the precision is high, and relative positions in three directions among the suspension propulsion windings can be better ensured compared with a framework-free structure.
By way of example, the relative positions of four rectangular coils in total for two levitation coils can be determined as follows: and bolt holes are formed in the supporting framework, and the supporting framework is placed in a potting grinding tool through the bolt holes on the supporting framework for positioning before potting.
In addition, the bolt hole can also be used for installing the integrated suspension propulsion module, and the module can be installed on the magnetic suspension track by matching the bolt with the bolt hole on the supporting framework.
According to an embodiment of the present invention, the propulsion coil assembly 4 is a propulsion coil wrapped with a soft semi-conductive material.
Therefore, the insulation protection requirement of the propulsion coil can be met.
Fig. 3 shows a cross-sectional view along a-a in fig. 1.
One example of a propulsion coil assembly according to the present invention is described below in conjunction with figure 3.
As shown in fig. 3, the propulsion coil assembly 4 includes a propulsion coil winding 41, an insulating layer 42, a winding former 43, and a grounded semi-conductive layer 44.
The propulsion coil assembly 4 according to the invention can be obtained in the following manner: winding the propulsion coil winding 41 on the winding framework 43 to ensure the dimensional accuracy; after winding, binding the high-voltage propulsion coil by using a mica insulating tape (namely, the wound propulsion coil and the wound framework are wound together by wrapping the mica insulating tape), and impregnating varnish for curing to form an insulating layer 42 of the high-voltage propulsion coil; and then uniformly coating the surface of the cured propulsion coil with a grounding semi-conductive layer 44 to obtain the propulsion coil assembly.
For example, the winding frame may have a hollow ring structure, so as to ensure sufficient forming accuracy after the softer propulsion coil winding is wound, and facilitate the winding frame to be taken down from the winding machine. The grounding semi-conducting layer is made of soft semi-conducting materials, and the winding framework is made of high-hardness composite insulating materials.
As described above, the high-voltage propulsion coil can be formed by curing a high-hardness bobbin or a mica tape in advance using an impregnating varnish as a support and a main insulator. Because the viscosity of the insulating varnish is far lower than that of epoxy resin, all gaps in the propulsion coil winding can be filled more effectively, and the occurrence of partial discharge is avoided. The main insulation thickness of the structure is finished when the propulsion winding assembly is prefabricated, and the influence of epoxy potting effect is avoided. And because the insulating layer is a binding and curing structure, the risk of insulating failure caused by contact surface cracks and gaps generated due to inconsistent thermal expansion coefficients of the conductor and the epoxy resin when the propulsion coil generates heat when current flows is completely avoided. In addition, the grounded semi-conducting layer is bound on the solidified and formed propulsion coil, so that an electric field on the surface of the propulsion coil is uniformly boosted, the effect of preventing the high electric field from influencing the performance of the suspension coil is achieved, and the situation that the propulsion coil generates partial discharge to epoxy resin to damage the epoxy resin structure is effectively avoided.
The size of each quarter-cylindrical propulsion coil positioning framework 23 is matched with the size of the winding framework 43 of the hollow annular structure in the propulsion coil assembly 4, and after the propulsion coil assembly is installed, the relative size relationship between the suspension coil and the propulsion coil in three directions can be ensured.
According to an embodiment of the present invention, the propulsion coil assembly 4 is led out to a grounding point outside the housing 5 through a lead wire.
That is, the grounding semiconductive layer 44 is led out to the outer surface of the module by a single conductor and connected to a track ground point.
Thereby, an electric field shield can be formed.
According to an embodiment of the invention, the high-voltage connector 7 is provided with a socket inside, and the wire nose 6 is pressed with the socket through a bolt.
According to one embodiment of the invention, the two high-voltage connectors 7 are staggered by a predetermined distance in the thickness direction of the housing.
For example, the two ends of the propulsion coil assembly can be led out of litz wires, scattered litz wires are connected with wire noses in a compression joint mode, and the wire noses are connected with sockets of high-voltage connectors embedded in the module in a compression joint mode through bolts to form a 90-degree right angle. The outgoing line direction of the high-voltage connectors is parallel to the ground, and the two high-voltage connectors are staggered by the distance of the diameter of an external cable in the thickness direction of the shell (the thickness of the module). Thus, when the high-voltage connector is connected to an external cable, no interference occurs.
Fig. 4 is a schematic diagram illustrating the force directions of the lateral sides of the levitation coil in an integrated levitation propulsion module according to an embodiment of the invention.
As can be seen from the stress directions of the four transverse sides of the suspension coil shown in fig. 4, only the transverse side conductor at the uppermost layer of the suspension coil is subjected to an outward tensile force, and the other sides of the conductor are subjected to a pressure towards the installation wall surface. Therefore, in actual work, the transverse side conductor at the uppermost layer generates outward bending moment on the resin shell, and because the resin on the surface of the module is thinner, the traditional module of the pure epoxy potting coil is easy to bend and generate fatigue cracks. In the invention, the suspension coil is wound on the high-strength composite material support framework, and the conductor at the uppermost layer is bound into the prefabricated groove of the support framework, so that the outward tensile force applied to the conductor at the uppermost layer in actual work is transmitted to the support framework through the binding belt and then transmitted to the bolt on the support framework, thereby greatly reducing the load on brittle resin and also greatly reducing the thickness of the resin layer on the surface of the suspension coil.
In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
It should be noted that the terms "first", "second", and the like are used to define the components, and are only used for convenience of distinguishing the corresponding components, and the terms have no special meanings unless otherwise stated, and therefore, the scope of the present invention should not be construed as being limited.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
