Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, and in particular to a maintenance device for a transformer tap changer. Background Art

[0002] With the development of intelligent power system, this transformer tap changer maintenance device is needed to accurately control the voltage stability of the power grid. Modern power systems have higher and higher requirements for voltage quality. Voltage fluctuations in the power grid may affect the normal operation of many electrical equipment. The transformer tap changer maintenance device can change the voltage ratio by adjusting the tap of the transformer, thereby stabilizing the output voltage and adapting to different load requirements. Among them, the "a transformer tap changer connection contact maintenance device" disclosed in the publication number "CN118874905A" has solved the various disadvantages of the existing maintenance device, that is, since all angles of the contacts need to be cleaned, it is necessary to constantly take out the telescopic rod and then adjust the angle of the scouring pad, which is cumbersome to operate. However, in actual use, the maintenance device still has many defects, such as: the existing maintenance device may have difficulties in component maintenance and replacement. For example, complex tools and operating procedures may be required to disassemble and replace key components (such as moving rods, cleaning components, etc.). At the same time, the existing maintenance device only focuses on the basic functions of the tap changer and does not have an integrated cleaning function. During long-term operation, dust and dirt may accumulate in the terminal board and the terminal slot, affecting the electrical performance. Therefore, it is necessary to design a maintenance device for the transformer tap changer. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a maintenance device for a transformer tap changer.

[0004] The present invention is implemented by the following technical scheme: a maintenance device for a transformer tap changer, comprising a support assembly, the support assembly comprising a load-bearing fixed frame, a reinforced reinforcement frame is fixedly installed inside the load-bearing fixed frame, an anti-slip seat is fixedly installed inside the reinforced reinforcement frame, and further comprising: An adjustment component, the adjustment component comprising a first mounting plate, a circuit connection plate being fixedly mounted on an outer surface of the first mounting plate, a circuit connection groove being provided inside the circuit connection plate, and a first limiting groove being provided inside the circuit connection plate; A tap assembly, the tap assembly comprising a connection seat, a second limiting groove is provided inside the connection seat, and a current contact head is provided on the inner wall of the connection seat; The cleaning assembly comprises an auxiliary mounting plate, a mounting seat is fixedly mounted on the bottom of the auxiliary mounting plate, and a supporting seat is rotatably mounted inside the mounting seat.

[0005] As a further improvement of the above scheme, a second mounting plate is fixedly installed on the outer surface of the circuit connecting plate, a support frame is fixedly installed on the front end of the second mounting plate, a power rotating rod is rotatably installed inside the support frame, a driving gear disk is fixedly installed on the bottom of the power rotating rod, and a handle is fixedly installed on the top of the power rotating rod.

[0006] Through the above technical solution, the front end of the second mounting plate is fixedly installed with a support frame, and the power rotating rod is rotatably installed inside the support frame. Such a structural design enables the power rotating rod to be rotated in a stable frame. The bottom of the power rotating rod is fixedly installed with a driving gear plate, and the top is fixedly installed with a handle. This integrated structural design makes the connection between the various components tight, and the force transmission is more direct and effective. The fixed installation method can effectively disperse the various forces that the device is subjected to during operation, including the tension from the transformer line, the pressure generated by its own weight, and the external vibration impact force that may be received, thereby greatly enhancing the stability of the overall structure. This stability is the cornerstone of the reliable operation of the device, ensuring that the various components are not easily displaced or loosened during long-term operation.

[0007] As a further improvement of the above solution, a moving rod is fixedly installed inside the connecting seat by a fixed installation screw, and a tooth groove is opened on the outer surface of the moving rod, and the tooth groove is meshed with the driving gear disc.

[0008] Through the above technical solution, the movable rod is fixedly installed inside the connecting seat by means of a fixed installation screw. The fixing method of the fixed installation screw can ensure that the movable rod is firmly installed in the connecting seat. During the operation of the device, this stable connection method can ensure that the movable rod will not be displaced or loosened due to vibration and the like, thereby ensuring the normal operation of the entire device, thereby achieving precise adjustment of the position of the connecting seat. The precise adjustment of the position of the connecting seat further affects the connection between the contact head inside it and different connectors, ultimately achieving the purpose of precisely adjusting the voltage or current, which is of great significance in power system application scenarios with high requirements for voltage or current accuracy.

[0009] As a further improvement of the above solution, a third mounting plate is fixedly mounted on the bottom of the moving rod, an auxiliary mounting plate is threadedly mounted on the bottom of the third mounting plate, and a mounting seat is fixedly mounted on the bottom of the auxiliary mounting plate.

[0010] Through the above technical solution, the mounting seat is fixedly installed at the bottom of the auxiliary mounting plate. This connection method connects the components related to the moving rod and the components related to the mounting seat to form an integral structure. This integrity helps the various components to work together during the operation of the device, and also facilitates the assembly and maintenance of the device. When the device needs to be repaired, parts replaced or functions adjusted, this threaded connection can be relatively easy to disassemble. For example, when a component connected to the auxiliary mounting plate fails and needs to be replaced, it can be removed from the third mounting plate by simply rotating it without destroying the structure of the entire device.

[0011] As a further improvement of the above solution, a first clamping seat is fixedly installed inside the mounting seat, a first clamping groove is opened inside the mounting seat, and a supporting seat is rotatably installed inside the mounting seat.

[0012] Through the above technical solution, the first card seat and the first card slot provide a structural basis for the installation and limitation of the support seat. This integrated structural design realizes multiple functions in a limited space, so that the support seat can rotate stably in the mounting seat and be subject to certain limitations, thereby ensuring the stability and accuracy of the device in different working conditions.

[0013] As a further improvement of the above solution, a second card slot is provided at the bottom of the support base, and the second card slot matches the first card slot. A second card slot is fixedly installed on the top of the support base, and the second card slot matches the first card slot.

[0014] Through the above technical solution, this matching relationship enables the support base to achieve convenient structural conversion and positioning under different working conditions. For example, when the support plate needs to be flipped, the state of the support base can be easily changed through the cooperation of the card slot and the card seat, thereby adjusting the position of the entire cleaning assembly, which provides convenience for the operation and maintenance of the cleaning roller.

[0015] As a further improvement of the above scheme, a triangular support frame is threadedly installed on one side of the support seat, a support plate is fixedly installed on the top of the triangular support frame, multiple groups of cleaning rotating rods are rotatably installed inside the support plate, a limit seat is rotatably installed on the outer surface of the cleaning rotating rod, and the limit seat is slidably installed on the outer surface of the circuit connection plate.

[0016] Through the above technical solution, multiple groups of cleaning rotating rods are rotatably installed inside the support plate, and the outer surface of the cleaning rotating rod is rotatably installed with a limit seat, and the limit seat is slidably installed on the outer surface of the line connection plate. This structural design enables the cleaning rotating rod to rotate within a stable frame, and the limit seat can not only ensure the rotation of the cleaning rotating rod, but also limit the position of the cleaning rotating rod to a certain extent through the sliding installation relationship with the outer surface of the line connection plate, thereby ensuring the accuracy and stability of the cleaning roller when cleaning the line connection plate and the line connection groove.

[0017] As a further improvement of the above scheme, a cleaning roller is fixedly installed on the outer surface of the cleaning rotating rod, and the cleaning roller matches the line connecting groove. A force-bearing toothed disc is fixedly installed on the top of the cleaning rotating rod, and the force-bearing toothed disc is meshed with the first limiting groove.

[0018] Through the above technical solution, a force-bearing toothed disc is fixedly installed on the top of the cleaning rotating rod, and the force-bearing toothed disc is meshed with the first limiting groove. This meshing relationship can transmit the power generated when the moving rod moves to the cleaning rotating rod, thereby driving the cleaning roller to rotate for cleaning. This power transmission method links the adjustment function and the cleaning function of the device, so that the cleaning operation can be automatically performed while performing voltage adjustment related operations, thereby improving the integration and working efficiency of the device.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The present invention removes the line from the line connection groove to the inside of the line connection plate, and rotates the handle to drive the power rotating rod to rotate in the support frame, driving the driving toothed disc to rotate. At this time, the driving toothed disc will drive the moving rod to adjust due to the engagement with the card tooth groove. Since the connecting seat is slidably installed on the outer surface of the line connection plate through the second limiting groove, when the moving rod is driven, the connecting seat will slide horizontally on the surface of the line connection plate. At the same time, when the moving rod slides, the force-bearing toothed disc and the first limiting groove are engaged with each other, which will drive the cleaning rotating rod to rotate in the support plate. The rotation of the cleaning rotating rod and the cleaning roller will clean the surface of the line connection plate and the inside of the line connection groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] By connecting the transformer line to the line connection groove 203, installing it in the line connection plate 202, and using the first mounting plate 201 to install the adjustment component 2 inside the support component 1, the load-bearing fixed frame 101 and the reinforced reinforcement frame 102 can support the line connection plate 202, and the anti-slip seat 103 can enhance the anti-slip performance of the device. By rotating the handle 209, the power rotation rod 207 is driven to rotate in the support frame 206, driving the driving gear disc 208 to rotate. At this time, the driving gear disc 208 will drive the moving rod 305 to adjust due to the engagement with the card tooth groove 306.

[0027] A third mounting plate 307 is fixedly mounted on the bottom of the moving rod 305 , an auxiliary mounting plate 401 is threadedly mounted on the bottom of the third mounting plate 307 , and a mounting seat 402 is fixedly mounted on the bottom of the auxiliary mounting plate 401 .

[0030] After cleaning is completed, the second holder 407 will be moved out of the first slot 404 by rotating the support seat 405, and the limitation of the first slot 404 on the second holder 407 will be cancelled, and the second slot 406 will be used to clip it into the first holder 403 on the surface of the mounting seat 402 to ensure that it is fixed after the support plate 409 is turned over. The triangular support frame 408 can ensure the connection between the support seat 405 and the support plate 409, and the auxiliary mounting plate 401 and the third mounting plate 307 are in a threaded connection state. The cleaning component 4 can be disassembled as a whole from the bottom of the branch component 3, which is convenient for the subsequent replacement of the cleaning roller 412.

[0031] A triangular support frame 408 is threadedly installed on one side of the support seat 405, and a support plate 409 is fixedly installed on the top of the triangular support frame 408. Multiple sets of cleaning rotating rods 410 are rotatably installed inside the support plate 409. A limiting seat 411 is rotatably installed on the outer surface of the cleaning rotating rod 410, and the limiting seat 411 is slidably installed on the outer surface of the circuit connection plate 202.

[0032] A cleaning roller 412 is fixedly mounted on the outer surface of the cleaning rotating rod 410 , and the cleaning roller 412 matches the line connecting groove 203 . A force-bearing toothed disc 413 is fixedly mounted on the top of the cleaning rotating rod 410 , and the force-bearing toothed disc 413 meshes with the first limiting groove 204 .

[0033] When the moving rod 305 slides, the force-bearing toothed disc 413 and the first limiting groove 204 are meshed with each other, which will drive the cleaning rotating rod 410 to rotate in the support plate 409. By utilizing the rotation of the cleaning rotating rod 410, the surface of the circuit connection plate 202 and the inside of the circuit connection groove 203 are cleaned by the cleaning roller 412. When the cleaning component 4 is cleaning, the limiting seat 411 can be used to ensure that the support plate 409 is fixed to one side of the circuit connection plate 202.

[0034] The implementation principle of a maintenance device for a transformer tap changer in the embodiment of the present application is as follows: by connecting the line of the transformer into the line connection groove 203, installing it in the line connection plate 202, and using the first mounting plate 201 to install the adjustment component 2 inside the support component 1, the load-bearing fixing frame 101 and the strengthening reinforcement frame 102 can support the line connection plate 202, and the anti-slip performance of the device can be enhanced by using the anti-slip seat 103, and by rotating the handle 209, the power rotation rod 207 is driven to rotate in the support frame 206, and the driving toothed disc 208 is driven to rotate. At this time, the driving toothed disc 208 will drive the moving rod 305 to adjust due to the engagement with the card tooth groove 306. Since the connecting seat 301 is slidably installed on the outer surface of the line connection plate 202 through the second limiting groove 302, it will be on the moving rod 305. When driven, the connection base 301 is used to slide horizontally on the surface of the circuit connection plate 202. By moving the connection base 301, the current contact head 303 inside it is used to connect with connectors at different positions on the winding. When the current contact head 303 contacts a connector, the current of the transformer will flow through the connector, thereby determining the output voltage or current. When the current contact head 303 moves to the next connector, the current will be reconnected to the new connector, thereby changing the output voltage or current. Since the support frame 206 is fixed to the surface of the circuit connection plate 202 through the second mounting plate 205, when the power rotation rod 207 is driven, the moving rod 305 is driven to slide at the front end of the second mounting plate 205, and the moving rod 305 can be removed from the connection base 301 by twisting the fixed mounting screw 304; The line is removed from the line connection groove 203 to the line connection plate 202, and the handle 209 is rotated again to drive the moving rod 305 to slide again. When the moving rod 305 slides, the force-bearing toothed disc 413 and the first limiting groove 204 are meshed with each other, which will drive the cleaning rotating rod 410 to rotate in the support plate 409. By utilizing the rotation of the cleaning rotating rod 410, the surface of the line connection plate 202 and the line connection groove 203 are cleaned by the cleaning roller 412. When the cleaning component 4 is cleaning, the limiting seat 411 can be used to ensure that the support plate 409 is fixed to one side of the line connection plate 202. After cleaning is completed, the second holder 407 will be moved out of the first slot 404 by rotating the support seat 405, and the limitation of the first slot 404 on the second holder 407 will be cancelled, and the second slot 406 will be used to clip it into the first holder 403 on the surface of the mounting seat 402 to ensure that it is fixed after the support plate 409 is turned over. The triangular support frame 408 can ensure the connection between the support seat 405 and the support plate 409, and the auxiliary mounting plate 401 and the third mounting plate 307 are in a threaded connection state. The cleaning component 4 can be disassembled as a whole from the bottom of the branch component 3, which is convenient for the subsequent replacement of the cleaning roller 412.

[0035] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention.
