Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to an energy storage dry-type transformer. Background Technology

[0002] Integrated energy storage units help solve the problems of discontinuous and uncontrollable renewable energy power generation, ensuring a continuous and stable output of power from the power system. They serve as a hub for the balance and regulation of the new energy grid and are an important means of addressing the high-proportion consumption of renewable energy. An integrated energy storage converter-step-up unit typically consists of a transformer, high and low voltage switches, a PCS (Power Control System) main unit, a prefabricated structure box, and auxiliary control systems. One of the core components of an integrated energy storage unit is the transformer; the transformer in an integrated energy storage unit is typically an oil-immersed energy storage transformer or a dry-type energy storage transformer. Dry-type energy storage transformers are characterized by simple operation and maintenance, environmental friendliness, aesthetically pleasing appearance, and safe operation. Compared to oil-immersed energy storage transformers, oil-immersed energy storage transformers can dissipate heat through transformer oil circulation, resulting in strong heat dissipation capacity, while dry-type energy storage transformers can only dissipate heat through air convection, leading to poor heat dissipation capacity and lower heat dissipation efficiency. Utility Model Content

[0003] The main purpose of this utility model is to propose an energy storage dry-type transformer, which aims to solve the technical problems of poor heat dissipation capacity and low heat dissipation efficiency of energy storage dry-type transformers.

[0004] To achieve the above objectives, the energy storage dry-type transformer proposed in this utility model includes:

[0005] Base;

[0006] A winding structure, which is mounted on the base, includes a low-voltage winding and a high-voltage winding;

Each heat dissipation mechanism includes a heat dissipation fan and an angle adjustment component. The heat dissipation fan is rotatably mounted on a base, and its outlet is provided with a flow guide component. The heat dissipation fan blows air through the outlet and the flow guide component to the winding structure. The angle adjustment component is mounted on the base and connected to the heat dissipation fan. In one embodiment, the angle adjustment component includes a mounting plate, a hinge plate, and a lifting structure. The mounting plate is mounted on the base. The two opposite ends of the hinge plate are a lifting end and a hinge end, respectively. The hinge end is hinged to the mounting plate. The lifting structure is mounted on the mounting plate and the lifting end is supported by the lifting structure. The heat dissipation fan is supported and connected to the hinge plate. The lifting structure is used to drive the lifting end to rise and fall, thereby causing the hinge plate and the heat dissipation fan to rotate around the hinge end to adjust the orientation of the outlet.

[0008] In one embodiment, the lifting structure includes a support frame and a lifting drive component. The bottom of the support frame is connected to the drive shaft of the lifting drive component, and the lifting end is supported on the top of the support frame. The lifting drive component is used to drive the support frame to lift and lower via the drive shaft, thereby driving the lifting end to lift and lower.

[0009] In one embodiment, a slider is provided at the top of the support frame, and a groove is provided at the bottom of the hinge end. The groove extends from the hinge end toward the lifting end, and the slider is disposed in the groove and can slide in cooperation with the groove.

[0010] In one embodiment, the mounting plate is provided with two guide frames, which are located at opposite ends of the support frame. Each guide frame has a vertically extending guide groove on one side facing the support frame. Both ends of the support frame extend into the two guide grooves and slide in cooperation with the two guide grooves respectively.

[0011] In one embodiment, the airflow guiding assembly includes a plurality of airflow guiding blades spaced apart along the width direction of the air outlet, and the two ends of the airflow guiding blades are rotatably mounted on both sides of the air outlet along the length direction.

[0015] In one embodiment, both the low-voltage output terminal of the low-voltage winding and the high-voltage output terminal of the high-voltage winding are located close to the base.

[0016] The technical solution of this utility model involves setting multiple heat dissipation structures on the base, which surround the winding structure on the base. A cooling fan within the heat dissipation structure blows air onto the winding structure, removing heat and accelerating air convection, thus achieving efficient heat dissipation with good capacity and high efficiency. A guide component at the air outlet of the cooling fan effectively guides the airflow, allowing it to directly and accurately act on the heat-generating parts of the winding structure, further improving heat dissipation efficiency and capacity. Furthermore, an angle adjustment component allows for flexible adjustment of the orientation of the cooling fan outlet, enabling more precise airflow onto the heat-generating parts of the winding structure, achieving precise heat dissipation, and further enhancing the heat dissipation capacity and efficiency of the energy storage dry-type transformer provided by this utility model.

[0027] Dry-type energy storage transformers are characterized by simple operation and maintenance, environmental friendliness and pollution-free operation, aesthetically pleasing appearance, and safe operation. Compared to oil-immersed energy storage transformers, which rely on transformer oil circulation to remove heat and have strong heat dissipation capabilities, dry-type energy storage transformers can only dissipate heat through air convection, resulting in poor heat dissipation capacity and lower heat dissipation efficiency.

[0028] This utility model proposes an energy storage dry-type transformer 100.

[0029] Please see Figures 1 to 3 In one embodiment of this utility model, the energy storage dry-type transformer 100 includes a base 10, a winding structure 20, and a heat dissipation module 30. The winding structure 20 is mounted on the base 10 and includes a low-voltage winding 21 and a high-voltage winding 22. The heat dissipation module 30 includes multiple heat dissipation mechanisms 31, which are spaced apart around the winding structure 20. Each heat dissipation mechanism 31 includes a heat dissipation fan 32 and an angle adjustment component 33. The heat dissipation fan 32 is rotatably mounted on the base 10, and a flow guide component 34 is provided at the air outlet of the heat dissipation fan 32. The heat dissipation fan 32 blows air to the winding structure 20 through the air outlet and the flow guide component 34. The angle adjustment component 33 is mounted on the base 10 and connected to the heat dissipation fan 32. The angle adjustment component 33 drives the heat dissipation fan 32 to rotate relative to the base 10 to adjust the orientation of the air outlet.

[0030] The technical solution of this utility model involves setting multiple heat dissipation structures on the base 10, which surround the winding structure 20 on the base 10. A cooling fan 32 within the heat dissipation structure blows air onto the winding structure 20, removing heat and accelerating air convection, thus achieving efficient heat dissipation with good capacity and high efficiency. A guide component 34 at the air outlet of the cooling fan 32 effectively guides the airflow, allowing it to directly and accurately target the heat-generating parts of the winding structure 20, further improving heat dissipation efficiency and capacity. Furthermore, an angle adjustment component 33 allows for flexible adjustment of the orientation of the cooling fan 32's air outlet, enabling more precise airflow to the heat-generating parts of the winding structure 20, achieving precise heat dissipation and further enhancing the heat dissipation capacity and efficiency of the energy storage dry-type transformer 100 provided by this utility model.

[0031] In one embodiment of this utility model, the angle adjustment assembly includes a mounting plate 331, a hinge plate 332, and a lifting structure 333. The mounting plate 331 is mounted on the base 10. The two opposite ends of the hinge plate 332 are a lifting end 3322 and a hinge end 3321, respectively. The hinge end 3321 is hinged to the mounting plate 331. The lifting structure 333 is mounted on the mounting plate 331. The lifting end 3322 is supported by the lifting structure 333. The cooling fan 32 is supported and connected to the hinge plate 332. The lifting structure 333 is used to drive the lifting end 3322 to rise and fall, so as to drive the hinge plate 332 and the cooling fan 32 to rotate around the hinge end 3321 to adjust the orientation of the air outlet.

[0032] Specifically, such as Figure 1 and Figure 3 As shown, an mounting plate 331 is installed on the base 10, and a hinge plate 332 is provided on the mounting plate 331. The hinge end 3321 of the hinge plate 332 is hinged to the mounting plate 331. The lifting end 3322 can be driven to rise and fall by the lifting structure 333 provided on the mounting plate 331, so as to drive the hinge plate 332 and the cooling fan 32 installed on the hinge plate 332 to rotate around the hinge end 3321, thereby realizing the adjustment of the orientation of the air outlet of the cooling fan 32, which is simple and convenient.

[0033] In one embodiment of the present invention, the lifting structure 333 includes a support frame 3331 and a lifting drive 3332. The bottom of the support frame 3331 is connected to the drive shaft of the lifting drive 3332, and the lifting end 3322 is supported on the top of the support frame 3331. The lifting drive 3332 is used to drive the support frame 3331 to lift and lower through the drive shaft, so as to drive the lifting end 3322 to lift and lower.

[0034] Furthermore, such as Figure 2 As shown, the bottom of the support frame 3331 is connected to the drive shaft of the lifting drive component 3332. The lifting drive component 3332 can drive the support frame 3331 to rise and fall via the drive shaft, thereby driving the lifting end 3322 supported on the top of the support frame 3331 to rise and fall. This, in turn, drives the hinge plate 332 and the cooling fan 32 mounted on the hinge plate 332 to rotate around the hinge end 3321. The structure is simple. The lifting drive component 3332 can be a cylinder, hydraulic cylinder, or other existing technology.

[0035] In one embodiment of the present invention, a slider 3333 is provided on the top of the support frame 3331, and a groove 3311 is provided at the bottom of the hinge end 3321. The groove 3311 extends from the hinge end 3321 toward the lifting end 3322. The slider 3333 is disposed in the groove 3311 and can slide with the groove 3311.

[0036] Furthermore, such as Figure 2 and Figure 3As shown, a groove 3311 is provided at the bottom of the hinge end 3321 of the hinge plate 332, and a slider 3333 is provided at the top of the support frame 3331. Through the sliding engagement of the slider 3333 and the groove 3311, the hinge plate 332 moves more smoothly and steadily when driving the cooling fan 32 to rotate around the hinge end 3321. During the lifting process of the lifting end 3322 driven by the lifting structure 333, the slider 3333 slides in the groove 3311, effectively limiting the swing trajectory of the hinge plate 332 and preventing it from shaking or deviating during movement.

[0037] In one embodiment of the present invention, two guide frames 334 are provided on the mounting plate 331. The two guide frames 334 are located at opposite ends of the support frame 3331, and each guide frame 334 has a vertically extending guide groove 3341 on one side facing the support frame 3331. The two ends of the support frame 3331 extend into the two guide grooves 3341 respectively and slide in cooperation with the two guide grooves 3341 respectively.

[0038] Furthermore, such as Figure 2 and Figure 3 As shown, two guide frames 334 are located at opposite ends of the support frame 3331. The guide grooves 3341 extending vertically on them slide against the ends of the support frame 3331, forming a stable lateral guiding constraint. During the lifting process of the lifting drive 3332 driving the support frame 3331 to rise and fall, the support frame 3331 not only relies on the axial thrust of the lifting drive 3332, but also obtains lateral limitation through sliding contact with the guide grooves 3341, so that the support frame 3331 can drive the hinge end 3321 to rise and fall more smoothly.

[0039] In one embodiment of the present invention, the air guiding component 34 includes a plurality of air guiding blades 341 spaced apart along the width direction of the air outlet, and the two ends of the air guiding blades 341 are rotatably mounted on both sides of the air outlet along the length direction.

[0040] Specifically, such as Figure 1 As shown, multiple guide vanes 341 are spaced apart along the width of the air outlet, which can evenly disperse the air blown out by the cooling fan 32 to various areas of the winding structure 20, thereby dissipating heat from the winding structure 20 more evenly and further improving the heat dissipation capacity and efficiency of the energy storage dry transformer 100 provided by this utility model.

[0041] In one embodiment of the present invention, the energy storage dry-type transformer 100 further includes a temperature monitoring component, which is disposed close to the winding structure 20 and is used to monitor the temperature value of the winding structure 20.

[0042] Specifically, the temperature monitoring component can monitor the temperature value of the winding structure 20. Based on the monitored temperature value, the angle adjustment component 33 drives the cooling fan 32 to rotate, thereby adjusting the orientation of the air outlet of the cooling fan 32. This allows for more precise heat dissipation of the winding structure 20, further improving the heat dissipation capacity and efficiency of the energy storage dry-type transformer 100 provided by this utility model.

[0043] In one embodiment of this utility model, the temperature monitoring component includes a plurality of temperature sensors arranged at vertical intervals.

[0044] Specifically, by using multiple temperature sensors spaced vertically, the temperature values ​​at different heights of the winding structure 20 can be monitored. Based on the temperature values ​​at each height of the winding structure 20, the orientation of the air outlet of the cooling fan 32 can be adjusted more precisely, thereby further improving the accuracy of heat dissipation for the winding structure 20.

[0045] In one embodiment of the present invention, the energy storage dry-type transformer 100 further includes multiple temperature monitoring components, which are arranged at intervals around the winding structure 20. The number of temperature monitoring components and the heat dissipation mechanism 31 are the same and correspond one-to-one.

[0046] Specifically, multiple temperature monitoring components are spaced apart around the winding structure 20, dividing the winding structure 20 into multiple temperature monitoring zones. The number of temperature monitoring components and heat dissipation structures corresponds one-to-one with the number of temperature monitoring zones. Each temperature monitoring component can monitor the temperature of its corresponding temperature monitoring zone, and each heat dissipation structure can dissipate heat to its corresponding temperature monitoring zone. The orientation of the air outlet of the cooling fan 32 in the heat dissipation mechanism 31 is adjusted according to the temperature values ​​monitored by each temperature monitoring component, allowing for more precise heat dissipation of the winding structure 20, resulting in better heat dissipation effect and higher heat dissipation efficiency.

[0047] In one embodiment of this utility model, the low-voltage output terminal 211 of the low-voltage winding 21 and the high-voltage output terminal 221 of the high-voltage winding 22 are both located close to the base 10.

[0048] Specifically, as shown in the figure, both the low-voltage output terminal 211 and the high-voltage output terminal 221 are located close to the base 10, facilitating connection to external circuits and simplifying wiring. During installation, the connecting wires can be directly led out from near the base 10, reducing cable length and complexity, improving installation efficiency, and lowering construction difficulty and cost.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
