Description

Technical Field

[0001] This utility model relates to the field of step-up transformer technology, and specifically to a step-up transformer with a coupling structure. Background Technology

[0002] A step-up transformer is a common electrical device that uses the law of electromagnetic induction to increase the input voltage level through energy conversion between the primary and secondary windings. The main function of a step-up transformer is to increase voltage and reduce current intensity, helping to reduce energy loss during power transmission. A step-up transformer consists of a primary winding and a secondary winding, with the primary winding having fewer turns than the secondary winding to achieve the voltage increase. During operation, a step-up transformer generates a significant amount of heat, primarily from the hysteresis and eddy current losses in the core and the resistive losses in the coils. As the temperature rises, the transformer's insulation performance and lifespan are affected, potentially leading to malfunctions. Therefore, cooling fans are needed to dissipate heat and ensure the transformer's normal operation.

[0003] Currently, when using cooling fans to dissipate heat from transformers, there is a lack of structures that use couplings to tightly connect the input shaft of the cooling fan to the drive equipment. Furthermore, there is no function to lubricate the couplings, which easily leads to severe friction between components, reducing the service life of components such as couplings, affecting the stability and efficiency of transmission, and resulting in poor heat dissipation. Therefore, we propose a step-up transformer with a coupling structure. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a step-up transformer with a coupling structure. When using a cooling fan to dissipate heat from the transformer, this new step-up transformer has a structure that uses a coupling to tightly connect the input shaft of the cooling fan with the input shaft of the DC motor. Moreover, the coupling can be lubricated to avoid severe friction between components, extend the service life of the coupling and other components, and thus enhance the stability and efficiency of the transmission, thereby effectively improving the heat dissipation effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is a step-up transformer with a coupling structure, including a step-up transformer housing, a lubrication assembly and a coupling. The step-up transformer body is arranged inside the step-up transformer housing. A mounting shell is arranged on one side of the step-up transformer housing. A cooling fan is installed inside the mounting shell. An input shaft is arranged inside the cooling fan. A DC motor is arranged at one end of the step-up transformer housing. The output end of the DC motor is connected to a drive shaft. A coupling is sleeved around the drive shaft and the input shaft.

[0006] A lubrication assembly is provided between the DC motor and the step-up transformer housing. The lubrication assembly includes a lubricating oil storage tank, an oil delivery pipe, and a nozzle. One end of the oil delivery pipe is connected to the lubricating oil storage tank, and a nozzle is provided at the bottom of the other end of the oil delivery pipe. The nozzle is located at the upper end of the coupling.

[0007] By adopting the above technical solution, this novel step-up transformer has a structure that uses a coupling to tightly connect the input shaft of the cooling fan with the input shaft of the DC motor. Moreover, it can lubricate the coupling, avoid severe friction between components, extend the service life of the coupling and other components, thereby enhancing the stability and efficiency of the transmission, and thus effectively improving the heat dissipation effect.

[0008] Specifically, a base plate is connected to the bottom of one end of the step-up transformer housing, a mounting base is fixed to the top of the base plate, the DC motor is mounted on the top of the mounting base, and the bottom of the lubricating oil storage tank is connected to the base plate.

[0009] Specifically, the lubrication assembly also includes an oil pump, which is mounted on an oil delivery pipe.

[0010] Specifically, a bearing is provided on one side of the mounting housing through a reserved opening.

[0011] By adopting the above technical solution, one end of the input shaft can pass through the central hole inside the bearing and connect to the drive shaft, allowing the input shaft to rotate smoothly.

[0012] Specifically, the top of the lubricating oil storage tank is provided with an oil filling port, and the lower end of one side of the lubricating oil storage tank is provided with an oil outlet.

[0013] By adopting the above technical solution, the oil inlet facilitates the injection of lubricating oil into the lubricating oil storage tank, and the oil outlet facilitates the entry of the lubricating oil inside the lubricating oil storage tank into the oil delivery pipe.

[0014] Specifically, an annular connecting plate is fixed to one side of the mounting shell.

[0015] The beneficial effects of this utility model are:

[0016] (1) The step-up transformer with a coupling structure described in this utility model enables the drive shaft to be tightly connected to the input shaft, thereby enhancing the stability and efficiency of the transmission between the drive shaft and the input shaft, and thus enhancing the stability of the cooling fan during operation.

[0017] (2) The step-up transformer with a coupling structure described in this utility model can spray lubricating oil onto the coupling with a nozzle. The lubricating oil can then penetrate to the connection between the coupling and the drive shaft and the input shaft, thereby playing a lubricating role and reducing the friction between the coupling and the drive shaft and the input shaft, thus extending the service life of the coupling, drive shaft and input shaft.

[0018] (3) The step-up transformer with a coupling structure described in this utility model has a vent hole on the other side of the transformer housing corresponding to the cooling fan, so that the transformer body can be cooled and protected by air convection to ensure the normal operation of the transformer body.

[0025] To extend the service life of components such as couplings, enhance transmission stability and efficiency, and improve heat dissipation, such as... Figure 1-3As shown, the present invention discloses a step-up transformer with a coupling structure, comprising a step-up transformer housing 1, a lubrication assembly 6, and a coupling 12. The step-up transformer body 2 is disposed inside the step-up transformer housing 1. A mounting shell 7 is disposed on one side of the step-up transformer housing 1. A cooling fan 8 is installed inside the mounting shell 7. An input shaft 9 is disposed inside the cooling fan 8. A DC motor 5 is disposed at one end of the step-up transformer housing 1. A drive shaft 10 is connected to the output end of the DC motor 5. A coupling 12 is sleeved around the drive shaft 10 and the input shaft 9.

[0026] A lubrication assembly 6 is provided between the DC motor 5 and the step-up transformer housing 1. The lubrication assembly 6 includes a lubricating oil storage tank 601, an oil delivery pipe 602, and a nozzle 604. One end of the oil delivery pipe 602 is connected to the lubricating oil storage tank 601, and the nozzle 604 is provided at the bottom of the other end of the oil delivery pipe 602. The nozzle 604 is located at the upper end of the coupling 12.

[0027] In use, the coupling 12 enables the drive shaft 10 to be tightly connected to the input shaft 9, thereby enhancing the stability and efficiency of the transmission between the drive shaft 10 and the input shaft 9, and thus enhancing the stability of the cooling fan 8 during operation.

[0028] The oil pump 603 can draw lubricating oil from the lubricating oil storage tank 601 and deliver the lubricating oil to the nozzle 604 through the oil delivery pipe 602. The nozzle 604 can then spray the lubricating oil onto the coupling 12, allowing the lubricating oil to penetrate into the connection between the coupling 12 and the drive shaft 10 and the input shaft 9, thus providing lubrication and reducing the friction between the coupling 12 and the drive shaft 10 and the input shaft 9, thereby extending the service life of the coupling 12, the drive shaft 10, and the input shaft 9.

[0029] The step-up transformer housing 1 has a vent on the other side of the cooling fan 8, which can dissipate heat from the step-up transformer body 2 through air convection to ensure the normal operation of the step-up transformer body 2.

[0030] For example, such as Figure 1 As shown, a base plate 3 is connected to the bottom of one end of the step-up transformer housing 1, and a mounting base 4 is fixed to the top end of the base plate 3. The DC motor 5 is mounted on the top of the mounting base 4, and the bottom of the lubricating oil storage tank 601 is connected to the base plate 3.

[0033] When in use, oil pump 603 can promote the flow of lubricating oil.

[0034] For example, such as Figure 2 As shown, a bearing 15 is provided on one side of the mounting housing 7 by opening a reserved opening.

[0037] During use, the oil inlet 13 facilitates the injection of lubricating oil into the lubricating oil storage tank 601, and the oil outlet 14 facilitates the entry of the lubricating oil inside the lubricating oil storage tank 601 into the oil delivery pipe 602.

[0038] For example, such as Figure 2 As shown, an annular connecting plate 11 is fixed on one side of the mounting shell 7.

[0039] In use, the annular connecting plate 11 is connected to the step-up transformer housing 1 by screws.

[0040] When using this utility model, the user connects the power supply to the electrical equipment in this utility model, and puts the coupling 12 around the connection between the drive shaft 10 and the input shaft 9, so that the drive shaft 10 and the input shaft 9 are tightly connected.

[0041] Furthermore, personnel can inject lubricating oil into the lubricating oil storage tank 601 through the oil inlet 13, connect the inlet end of the oil supply pipe 602 to the outlet 14, and the oil pump 603 can draw the lubricating oil from the lubricating oil storage tank 601 and deliver the lubricating oil to the nozzle 604 through the oil supply pipe 602. The nozzle 604 can then spray the lubricating oil onto the coupling 12, and the lubricating oil can penetrate into the connection between the coupling 12 and the drive shaft 10 and the input shaft 9.

[0042] Furthermore, the step-up transformer housing 1 has a vent on the other side corresponding to the cooling fan 8, so that the step-up transformer body 2 can be cooled and protected by air convection to ensure the normal operation of the step-up transformer body 2.
