Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a coil spacer based on non-Newtonian fluid. Background Art

[0002] The characteristics of renewable energy generation differ significantly from those of traditional electrical loads. Traditional electrical loads, such as industrial equipment and residential electricity consumption, have relatively stable and predictable power demand. However, renewable energy generation, particularly wind and solar power, is highly intermittent and uncertain in its generation and temporal distribution, highly dependent on natural conditions such as wind speed, direction, and sunlight intensity. This inconsistency presents new challenges for power system operation. In power systems with high renewable energy penetration, the volatility of renewable energy generation can cause fluctuations in power flow distribution and voltage levels, causing currents in certain areas or equipment to exceed rated values, leading to overcurrent problems. Furthermore, the control strategies and protection mechanisms of renewable energy generation units can also affect the overcurrent characteristics of the power system. Consequently, the impact of overcurrent on transformers under traditional electrical loads differs from that experienced after the integration of renewable energy. The magnitude and direction of the electric forces also differ significantly, creating challenges for securing transformer components.

[0003] Transformer spacers are typically made of electrical laminated wood, primarily for insulation and support. They firmly support the transformer's coils and core, preventing displacement or deformation during operation and thus maintaining the transformer's structural integrity and performance stability. However, when an overcurrent flows through the transformer, the enormous electrodynamic forces impart significant rigidity to the laminated wood, causing significant vibration in the transformer and leading to significant noise. Furthermore, the coil spacers may deform or shift due to the immense mechanical stress, impacting the transformer's stable operation. Summary of the Invention

[0004] In view of this, the present invention proposes a coil pad based on non-Newtonian fluid, which aims to solve the problem in the prior art that when the transformer passes through an overcurrent, the transformer pad is subjected to a large rigid force, causing the transformer to vibrate and affecting the operation of the transformer.

[0005] The present invention proposes a coil gasket based on non-Newtonian fluid, which includes: two layers of electrical laminated wood; a non-Newtonian fluid structure arranged between the two layers of electrical laminated wood, which is used to dissipate external load force by utilizing the characteristics of non-Newtonian fluid.

[0006] Furthermore, in the above-mentioned coil pad based on non-Newtonian fluid, the non-Newtonian fluid structure includes: two non-Newtonian fluid modules, which are arranged between two layers of electrical laminated wood; and an airbag module, which is sandwiched between the two non-Newtonian fluid modules.

[0007] Furthermore, in the above-mentioned coil gasket based on non-Newtonian fluid, each non-Newtonian fluid module is a shear thickening non-Newtonian fluid module.

[0008] Furthermore, in the above-mentioned coil gasket based on non-Newtonian fluid, each non-Newtonian fluid module includes: a first shell, which is arranged between the electrical laminate wood and the airbag module, and the first shell is filled with a shear thickening non-Newtonian fluid filler.

[0009] Furthermore, in the above-mentioned coil pad based on non-Newtonian fluid, the airbag module includes: a second shell, arranged between two non-Newtonian fluid modules; multiple shear thickening non-Newtonian fluid airbags, arranged in the second shell; multiple shear thinning non-Newtonian fluid airbags, arranged in the second shell, and each shear thinning non-Newtonian fluid airbag and each shear thickening non-Newtonian fluid airbag are alternately distributed.

[0010] Furthermore, in the above-mentioned coil gasket based on non-Newtonian fluid, the shear-thinning non-Newtonian fluid airbags and the shear-thickening non-Newtonian fluid airbags are arranged in layers in the second shell, and the shear-thinning non-Newtonian fluid airbags and the shear-thickening non-Newtonian fluid airbags in each layer are alternately distributed, and the shear-thinning non-Newtonian fluid airbags and the shear-thickening non-Newtonian fluid airbags between two adjacent layers are also alternately distributed.

[0011] Furthermore, in the above-mentioned coil gasket based on non-Newtonian fluid, each shear-thickening non-Newtonian fluid airbag includes: a third shell, which is arranged in the second shell, and the third shell is filled with a shear-thickening non-Newtonian fluid filler.

[0012] Furthermore, in the above-mentioned coil gasket based on non-Newtonian fluid, each shear-thinning non-Newtonian fluid airbag includes: a fourth shell, which is arranged in the second shell, and the fourth shell is filled with a shear-thinning non-Newtonian fluid filler.

[0013] Furthermore, in the above-mentioned coil spacer based on non-Newtonian fluid, the two layers of electrical laminated wood and the two non-Newtonian fluid modules are symmetrically distributed with the airbag module as the symmetry line.

[0014] Furthermore, in the above-mentioned coil spacer based on non-Newtonian fluid, each layer of electrical laminated wood and the adjacent non-Newtonian fluid module, and each non-Newtonian fluid module and the airbag module are all bonded together.

[0015] In the present invention, a non-Newtonian fluid structure is arranged between two layers of electrical laminated wood. When an overcurrent passes through the transformer, a huge electric force applies a large external load force to the electrical laminated wood. The electrical laminated wood transfers the external load force to the non-Newtonian fluid structure. The non-Newtonian fluid structure uses the characteristics of the non-Newtonian fluid to dissipate the external load force, effectively reducing mechanical energy, thereby reducing the risk of deformation and displacement of the coil pad, enhancing the contact reliability between transformer components, ensuring the stable operation of the transformer, and reducing the vibration of the transformer and the noise generated by the transformer. This solves the problem in the prior art that when the transformer passes through an overcurrent, the transformer pad is subjected to a large rigid force, causing the transformer to vibrate and affecting the operation of the transformer.

[0022] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, unless there is a conflict, the embodiments of the present disclosure and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] See also Figures 1 to 5 , the figure shows the preferred structure of the coil pad based on non-Newtonian fluid in this embodiment. As shown in the figure, the coil pad based on non-Newtonian fluid is a coil pad for transformers used to prevent overcurrent shocks. The coil pad based on non-Newtonian fluid includes: two layers of electrical laminated wood 1 and a non-Newtonian fluid structure. Among them, the non-Newtonian fluid structure is arranged between the two layers of electrical laminated wood 1, and the non-Newtonian fluid structure is used to dissipate the external load force by utilizing the characteristics of non-Newtonian fluid. Specifically, when the transformer passes through an overcurrent, the coil pad is subjected to a large external load force, that is, a rigid force. The rigid force is first transmitted to the electrical laminated wood 1, and then transmitted to the non-Newtonian fluid structure. The non-Newtonian fluid structure converts the rigid force into a dissipative force, thereby realizing the dissipation of the rigid force.

[0024] It can be seen that in this embodiment, the non-Newtonian fluid structure is arranged between two layers of electrical laminated wood 1. When the transformer passes through an overcurrent, the huge electric force applies a large external load force to the electrical laminated wood 1. The electrical laminated wood 1 transfers the external load force to the non-Newtonian fluid structure. The non-Newtonian fluid structure uses the characteristics of the non-Newtonian fluid to dissipate the external load force, effectively reducing mechanical energy, thereby reducing the risk of deformation and displacement of the coil pad, enhancing the contact reliability between transformer components, ensuring the stable operation of the transformer, and reducing the vibration of the transformer, reducing the noise generated by the transformer, and solving the problem in the prior art that when the transformer passes through an overcurrent, the transformer pad is subjected to a large rigid force, causing the transformer to vibrate and affecting the operation of the transformer.

[0025] See also Figures 1 to 5 In the above embodiment, the non-Newtonian fluid structure includes two non-Newtonian fluid modules 2 and an airbag module 3. The two non-Newtonian fluid modules 2 are disposed between two layers of electrical laminate 1, and the airbag module 3 is sandwiched between the two non-Newtonian fluid modules 2. Specifically, each non-Newtonian fluid module 2 is a shear-thickening non-Newtonian fluid module.

[0026] The two layers of electrical laminated wood 1 and the two non-Newtonian fluid modules 2 are symmetrically arranged with the airbag module 3 as the symmetry line. The coil spacer based on non-Newtonian fluid comprises: an electrical laminated wood 1, a non-Newtonian fluid module 2, an airbag module 3, a non-Newtonian fluid module 2, and an electrical laminated wood 1 stacked sequentially from top to bottom, i.e., an electrical laminated wood 1, a shear-thickening non-Newtonian fluid module, an airbag module 3, a shear-thickening non-Newtonian fluid module, and an electrical laminated wood 1 stacked sequentially from top to bottom. Furthermore, the electrical laminated wood 1, the shear-thickening non-Newtonian fluid module, the airbag module 3, the shear-thickening non-Newtonian fluid module, and the electrical laminated wood 1 remain flat and continuous, and the five layers are continuously connected. The electrical laminated wood 1, the shear-thickening non-Newtonian fluid module, the airbag module 3, the shear-thickening non-Newtonian fluid module, and the electrical laminated wood 1 all have a rectangular structure.

[0027] Preferably, each layer of electrical laminate wood 1 is bonded to the adjacent non-Newtonian fluid module 2, and each non-Newtonian fluid module 2 is bonded to the airbag module 3. Specifically, each layer of electrical laminate wood 1 is bonded to the adjacent shear-thickening non-Newtonian fluid module using adhesive, such as soft glue. Each shear-thickening non-Newtonian fluid module is also bonded to the airbag module 3 using adhesive, such as soft glue.

[0028] Each non-Newtonian fluid module 2 includes: a first shell 21. The first shell 21 is arranged between the electrical laminate 1 and the airbag module 3. The first shell 21 is filled with a shear-thickening non-Newtonian fluid filler. The viscosity of the shear-thickening non-Newtonian fluid increases when subjected to an external load force, and the fluid returns to a liquid state when the external load force disappears. Specifically, the first shell 21 is in the shape of a rectangular parallelepiped, that is, a block structure. The material of the first shell 21 is a relatively thin insulating material, which can be epoxy resin or electrical laminate. The first shell 21 has a certain supporting capacity, but can transfer the energy of the external load force to the airbag module 3.

[0029] The airbag module 3 includes: a second shell 31, a plurality of shear-thickening non-Newtonian fluid airbags 32, and a plurality of shear-thinning non-Newtonian fluid airbags 33. The second shell 31 is disposed between the two non-Newtonian fluid modules 2, i.e., the second shell 31 is disposed between the two shear-thickening non-Newtonian fluid modules. Specifically, the second shell 31 is in the shape of a rectangular parallelepiped, i.e., a block structure. The second shell 31 is made of a relatively thin insulating material, which may be epoxy resin or electrical laminated wood. The second shell 31 has a certain supporting capacity, but can transfer the energy of the external load force to the interior.

[0030] Multiple shear-thickening non-Newtonian fluid airbags 32 are disposed in the second shell 31 , and multiple shear-thinning non-Newtonian fluid airbags 33 are also disposed in the second shell 31 . Moreover, the shear-thinning non-Newtonian fluid airbags 33 and the shear-thickening non-Newtonian fluid airbags 32 are alternately distributed in the second shell 31 .

[0031] Preferably, see Figure 2 and Figure 5 The shear-thinning non-Newtonian fluid airbags 33 and the shear-thickening non-Newtonian fluid airbags 32 are arranged in layers within the second shell 31. The shear-thinning non-Newtonian fluid airbags 33 and the shear-thickening non-Newtonian fluid airbags 32 in each layer are alternately distributed. The shear-thinning non-Newtonian fluid airbags 33 and the shear-thickening non-Newtonian fluid airbags 32 between two adjacent layers are also alternately distributed. Specifically, multiple layers and multiple columns are arranged within the second shell 31. That is, the shear-thinning non-Newtonian fluid airbags 33 and the shear-thickening non-Newtonian fluid airbags 32 in the second shell 31 are arranged in layers in the horizontal direction and in columns in the vertical direction. The shear-thinning non-Newtonian fluid airbags 33 and the shear-thickening non-Newtonian fluid airbags 32 in each layer are alternately distributed. The shear-thinning non-Newtonian fluid airbags 33 and the shear-thickening non-Newtonian fluid airbags 32 in each column and between the upper and lower layers are also alternately distributed.

[0032] Each shear-thickening non-Newtonian fluid airbag 32 includes a third shell. The third shell is disposed within the second shell 31 and is filled with a shear-thickening non-Newtonian fluid filler. The viscosity of the shear-thickening non-Newtonian fluid increases under external loads, and the fluid returns to a liquid state when the external loads disappear. Specifically, the third shell is made of a thin insulating material, such as epoxy resin or electrical laminate, and the second shell 31 has a certain degree of support.

[0033] Each shear-thinning non-Newtonian fluid airbag 33 includes a fourth shell. The fourth shell is disposed within the second shell 31 and is filled with a shear-thinning non-Newtonian fluid filler. When subjected to an external load, the viscosity of this shear-thinning non-Newtonian fluid decreases and its fluidity increases; when the external load disappears, its fluidity decreases. Specifically, the fourth shell is made of a thin insulating material, such as epoxy resin or electrical laminate, and has a certain degree of support capacity.

[0034] An external load is applied to the electrical laminate 1, which in turn transmits the load to the shear-thickening non-Newtonian fluid module. The viscosity of the shear-thickening non-Newtonian fluid within the module increases, transmitting the force to the airbag module 3. The shear-thickening non-Newtonian fluid airbag 32 within the airbag module transmits the force, while the shear-thinning non-Newtonian fluid airbag 33 dissipates the force, reducing displacement and deformation.

[0035] The mechanical behavior of shear-thickening non-Newtonian fluids is remarkably reversible under external forces. When the fluid is subjected to a high strain rate under external load, its viscosity increases dramatically, and even exhibits solid-like behavior. When the external load is removed and the fluid is subjected to a low strain rate, it returns to a liquid state. The mechanical behavior of shear-thinning non-Newtonian fluids, on the other hand, is reversible under external forces. When the fluid is subjected to a low strain rate under external load, its viscosity decreases dramatically, and its fluidity increases. When the external load is removed and the fluidity is subjected to a high strain rate, its fluidity decreases.

[0036] The shear-thickening non-Newtonian fluid module rapidly solidifies when the coil pad based on the non-Newtonian fluid is subjected to a large force, transmitting the force to the airbag module 3. The shear-thickening non-Newtonian fluid airbags 32 and shear-thinning non-Newtonian fluid airbags 33 in the airbag module 3 are alternately distributed. When the airbag module 3 is subjected to a large force, the shear-thickening non-Newtonian fluid airbags 32 transmit the force, while the shear-thinning non-Newtonian fluid airbags 33 dissipate the force, thus dissipating the force. This reduces displacement and deformation, and also acts as a vibration dampening agent.

[0037] The extent to which the external force is dissipated depends on the ratio of shear-thinning non-Newtonian fluid pockets to shear-thickening non-Newtonian fluid pockets.

[0038] As the outermost layer, the electrical laminated wood 1 provides basic structural support and maintains sufficient compressive strength under normal conditions to prevent deformation of the coil block. Furthermore, the electrical laminated wood 1 provides a solid foundation for the entire coil block and serves as the first point of contact for external loads (such as electrodynamic forces). When impacted by external loads, it immediately transfers the force to the internal shear-thickening non-Newtonian fluid module.

[0039] The shear-thickening non-Newtonian fluid within the shear-thickening non-Newtonian fluid module exhibits shear-thickening properties. Under high strain rates (i.e., rapidly applied external loads), its viscosity increases rapidly, exhibiting solid-like behavior, while at low strain rates it reverts to a liquid state. In the event of a sudden overcurrent shock, the shear-thickening non-Newtonian fluid instantly hardens, effectively preventing the external load from directly acting on more fragile components and transferring the force to the airbag module 3. The upper and lower layers of the shear-thickening non-Newtonian fluid module form a protective barrier, enhancing the stability of the coil block's overall structure.

[0040] The airbag module 3 includes alternatingly distributed shear-thickening non-Newtonian fluid airbags 32 and shear-thinning non-Newtonian fluid airbags 33, wherein the shear-thickening non-Newtonian fluid airbags 32 harden when subjected to force, while the shear-thinning non-Newtonian fluid airbags 33 become more fluid. When the external load force from the outside is transmitted to the airbag module 3 through the shear-thickening non-Newtonian fluid module, the shear-thickening non-Newtonian fluid airbags 32 continue to transmit force, while the shear-thinning non-Newtonian fluid airbags 33, due to increased fluidity, can consume part of the energy and achieve a vibration reduction effect. The airbag module 3 not only reduces the external load force that ultimately reaches the underlying material, but also reduces the vibration level of the overall coil pad system through internal energy dissipation.

[0041] The electrical laminated wood 1, the shear-thickening non-Newtonian fluid module, the airbag module 3, the shear-thickening non-Newtonian fluid module and the electrical laminated wood 1 work together to form a highly efficient energy absorption and dispersion structure. First, the external electrical laminated wood 1 receives and preliminarily disperses the impact force. Then, the shear-thickening non-Newtonian fluid module further enhances its compressive strength through its own mechanical behavior. Finally, the shear-thickening non-Newtonian fluid airbag 32 and the shear-thinning non-Newtonian fluid airbag 33 in the airbag module 3 work together to transmit the necessary support force on the one hand and dissipate excess energy through internal friction and other means on the other hand. This can achieve the purpose of reducing deformation and displacement, thereby improving the contact reliability between transformer components, enhancing the ability of the coil gasket to resist overcurrent impact, extending its service life, and ensuring the continuous power supply capability of the power system.

[0042] The upper and lower layers of electrical laminated wood 1 in this embodiment provide compressive strength under normal working conditions, so that the coil gasket is not easily deformed. The middle two layers of shear thickening non-Newtonian fluid modules provide compressive strength when the external force suddenly increases when a large current passes through, so that the coil gasket is not easily deformed. When the external force of the airbag module 3 suddenly increases, the shear thickening non-Newtonian fluid airbag 32 and the shear thinning non-Newtonian fluid airbag 33 offset each other's partial force, thereby achieving the effect of increasing the overall compressive strength of the gasket.

[0043] It can be seen that in this embodiment, the non-Newtonian fluid structure is arranged between two layers of electrical laminated wood. When the transformer passes an overcurrent, the huge electric force exerts a large external load force on the electrical laminated wood. The electrical laminated wood transfers the external load force to the non-Newtonian fluid structure. The non-Newtonian fluid structure uses the characteristics of the non-Newtonian fluid to dissipate the external load force, effectively reducing mechanical energy, thereby reducing the risk of deformation and displacement of the coil pad, enhancing the contact reliability between the transformer components, ensuring the stable operation of the transformer, and reducing the vibration of the transformer and the noise generated by the transformer. The coil pad based on non-Newtonian fluid not only improves the transformer's own ability to resist overcurrent, but also extends the service life of the transformer, ensures the continuous power supply capability of the power system, and reduces the economic losses and social impact caused by power outages.
