Description

Technical Field

[0001] The present invention belongs to the technical field of transformers, and more specifically, particularly relates to a shock-absorbing and noise-reducing housing device for a transformer. Background Art

[0002] An oil-immersed transformer is a power transformer that uses transformer oil as an insulating and cooling medium. In practical applications, the equipment usually requires the following technologies: 1. The iron core, which constitutes the magnetic circuit of the transformer and provides a low-magnetic-resistance path for the magnetic flux; 2. The winding, which converts the input electrical energy between different voltage levels; 3. The oil tank, which houses the transformer oil and provides mechanical support and protection for the iron core and winding; 4. The housing, and the reinforcing ribs are used to enhance the structural strength of the transformer; When an alternating current passes through the primary winding, an alternating magnetic flux will be generated in the iron core. This alternating magnetic flux passes through both the primary winding and the secondary winding at the same time. According to the law of electromagnetic induction, the changing magnetic flux will generate an induced electromotive force in the winding. However, during the use process, there are the following deficiencies: 1. The housing of the oil-immersed transformer is made of steel plate and has sufficient strength and stiffness. Due to the magnetostriction of the iron core and the electromagnetic force in the winding, a certain degree of vibration will be generated. The vibration will cause the components inside the transformer, such as the iron core, winding, and insulating materials, to bear alternating stress, which is likely to lead to component fatigue, loosening, or even damage, increasing the risk of short circuit.

[0003] 2. During the operation of the transformer housing, vibration will be generated. Due to the vibration of the iron core and winding, resonance will occur, amplifying the noise. At the same time, after the connection parts of the housing are loosened after long-term use, noise will also be generated under the action of vibration. The noise will interfere with the transmission of signals such as communication, radio, and television in the surrounding area, affecting the normal use of the equipment. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a shock-absorbing and noise-reducing housing device for a transformer to solve the above problems.

[0005] A shock-absorbing and noise-reducing housing device for a transformer includes a housing body, a heat dissipation oil tank, and an insulating support chassis. At least two shock-absorbing components are provided at the bottom end of the housing body. Each shock-absorbing component includes a shock-absorbing support rod, a buffer spring, a linkage rotating seat, and a connecting arm. Each shock-absorbing support rod is designed in a spiral shape. Each shock-absorbing support rod is fixed on the outside of the buffer spring. Each shock-absorbing support rod is symmetrically installed, and the shock-absorbing support rod is installed at an inclined angle. Each linkage rotating seat is rotatably connected to both ends of the shock-absorbing support rod. A rubber soft pad is fixedly installed at the end of each linkage rotating seat.

[0006] Preferably, two symmetrically installed reciprocating rack substrates are slidably mounted on the top end of each of the insulating support chassis. Two tilting load-bearing rods connected to the connecting arms are rotatably mounted at both ends of each of the reciprocating rack substrates. Multi-stage compressed guiding and reset rods are fixedly mounted at both side ends of each of the reciprocating rack substrates. Two grooves for docking with the reciprocating rack substrates are formed at the top end of the insulating support chassis; Two driving gear units for docking with the reciprocating rack substrates are rotatably mounted at the top end of the insulating support chassis. A gear ring is fixedly mounted at the end of the driving gear unit; Two driving gear units for docking with the reciprocating rack substrates are rotatably mounted at the top end of the insulating support chassis. A gear ring is fixedly mounted at the end of the driving gear unit.

[0007] Preferably, two sealing and locking circular plates for sealed connection are fixedly mounted at the bottom end of the heat dissipation oil tank. A filtering assembly is fixedly mounted at the top end of each of the sealing and locking circular plates. Each filtering assembly includes a diversion sleeve, an oil separation core, and a metal retaining ring; A downward conical groove is formed at the top end of each of the diversion sleeves. Each of the oil separation cores is designed with multiple layers; Multiple drainage ports are formed at the bottom end of each of the metal retaining rings. The bottom end of each of the metal retaining rings is connected to the sealing and locking circular plate.

[0008] Preferably, a rotary sliding push rod for docking with the diversion sleeve is rotatably mounted inside each of the sealing and locking circular plates. A conical sleeve for docking with the diversion sleeve is fixedly mounted at the top end of each of the rotary sliding push rods; A locking connection sleeve for guiding connection is fixedly mounted on the surface of each of the rotary sliding push rods. At least two centering guiding thin sheets for support are fixedly mounted on the surface of each of the locking connection sleeves; An airtight base is rotatably mounted inside each of the sealing and locking circular plates. A rotary blade type heat dissipation frame for docking and sliding with the centering guiding thin sheets is fixedly mounted at the top end of each of the airtight bases.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, shock-absorbing rods are installed at the bottom end of the outer shell body. Multiple shock-absorbing rods support the outer shell body at the same time. A buffer spring is installed outside the shock-absorbing rod. The buffer spring is a compressible structure. By the inclined compression of the shock-absorbing rod, the transmission direction and path of vibration can be changed, reducing the transmission of vibration to the installation foundation and surrounding structures, effectively reducing the loosening and wear of components such as windings and iron cores inside the outer shell body due to vibration, and ensuring the stable performance of the transformer.

[0010] In the present invention, the shock-absorbing struts are installed at the bottom end of the outer shell body. Multiple shock-absorbing struts support the outer shell body simultaneously. At the same time, buffer springs are installed on the outer sides of the shock-absorbing struts. The buffer spring is a compressible structure. A multi-stage noise reduction structure is formed by the rubber soft pads on the surface of the linkage swivel base and the shock-absorbing struts. The shock-absorbing struts first perform preliminary processing on the main vibrations of the transformer to reduce the energy and amplitude of the vibrations. Then, the rubber soft pads further buffer and absorb the remaining vibrations after being processed by the shock-absorbing struts, further reducing vibrations and noise.

[0011] In the present invention, the heat dissipation oil tank stores oil inside. The oil enters the inside of the tilting load-bearing rod through the groove at the top end of the diversion sleeve. The oil separation core continuously filters and adsorbs the oil flowing inside the heat dissipation oil tank, can adsorb the moisture in the oil, keep the water content of the oil at a low level, and improve the electrical performance and stability of the oil.

[0012] In the present invention, with the movement of the outer shell body, the sealing and locking circular plate moves. At the same time, the end of the rotary sliding push rod is fixedly connected to the insulating support chassis. The rotary sliding push rod can slide inside the sealing and locking circular plate. At the same time, the conical sleeve and the diversion sleeve are in a mutually sliding state. The oil inside the heat dissipation oil tank is pushed into the inside of the oil separation core through the conical sleeve, accelerating the filtering speed.

[0013] In the present invention, by clamping the centering guide thin sheet with the rotary blade type heat dissipation frame, the rotating rotary sliding push rod generates a force on the rotary blade type heat dissipation frame, causing the sealed base to drive the rotary blade type heat dissipation frame to rotate inside the oil separation core. The rotational movement makes the flow path of the oil inside the oil separation core more complex and irregular, increasing the residence time and flow distance of the oil inside the oil separation core. The oil has more time to contact the oil separation core and the rotary blade type heat dissipation frame, improving the heat transfer efficiency and contributing to the reduction of the oil temperature.

Specific embodiments

[0016] The following further describes in detail the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0017] Please refer to Figure 1 - Figure 8 , the present invention provides a transformer shock-absorbing and noise-reducing outer shell device, including an outer shell body 11, a heat dissipation oil tank 12 and an insulating support chassis 13. At least two shock-absorbing components are provided at the bottom end of the outer shell body 11. Each shock-absorbing component includes a shock-absorbing strut 14, a buffer spring 15, a linkage swivel base 16 and a connecting arm 17. Each shock-absorbing strut 14 is designed in a spiral shape. Each shock-absorbing strut 14 is fixed on the outside of the buffer spring 15. Each shock-absorbing strut 14 is symmetrically installed, and the shock-absorbing strut 14 is installed at an inclined angle. Each linkage swivel base 16 is rotatably connected to both ends of the shock-absorbing strut 14. A rubber soft pad is fixedly installed at the end of each linkage swivel base 16. The rubber soft pad can isolate the direct contact between metal components, reduce the damage of components caused by electrochemical corrosion, prevent safety accidents such as electrical short circuits or electric leakage between the transformer and other metal components, and improve electrical safety; The inclined shock-absorbing strut 14 can absorb and buffer the vibration generated during the operation of the outer shell body 11 in multiple directions. The symmetrically installed shock-absorbing struts 14 can evenly distribute the weight of the transformer to the surface of the insulating support chassis 13 at the same time, avoiding local stress concentration, making the foundation stress more uniform, improving the stability and safety of the overall structure. The inclined compression of the shock-absorbing strut 14 can change the transmission direction and path of the vibration, reduce the transmission of vibration to the installation foundation and surrounding structures, effectively reduce the loosening and wear of components such as windings and iron cores inside the outer shell body 11 due to vibration, and ensure the stable performance of the transformer; ​It is installed at the bottom end of the housing body 11 through shock-absorbing struts 14. Multiple shock-absorbing struts 14 support the housing body 11 simultaneously. At the same time, buffer springs 15 are installed on the outer sides of the shock-absorbing struts 14. The buffer springs 15 are compressible structures. The two ends of the buffer springs 15 are rotationally connected by linkage turntables 16. When the housing body 11 compresses the shock-absorbing struts 14, the shock-absorbing struts 14 can rotate and compress inside the linkage turntables 16. Through the shock-absorbing effect of the shock-absorbing struts 14, the noise generated by the vibration of the transformer is reduced, and the overall noise level during the operation of the transformer is lowered. The rubber soft pads on the surfaces of the linkage turntables 16 and the shock-absorbing struts 14 form a multi-stage noise reduction structure. The shock-absorbing struts 14 first conduct preliminary treatment on the main vibration of the transformer to reduce the energy and amplitude of the vibration, and then the rubber soft pads conduct secondary buffering and absorption on the vibration remaining after the treatment by the shock-absorbing struts 14, further reducing the vibration and noise; Two symmetrically installed reciprocating rack substrates 19 are slidably installed at the top ends of each insulating support chassis 13. Two tilting load-bearing rods 21 connected to the connecting arms 17 are rotationally installed at both ends of each reciprocating rack substrate 19. Multi-stage compressed guiding and resetting rods 22 are fixedly installed at both side ends of each reciprocating rack substrate 19. Two grooves for docking with the reciprocating rack substrates 19 are formed at the top end of the insulating support chassis 13. Through the pressure applied by the housing body 11 to the top ends of the shock-absorbing struts 14, the shock-absorbing struts 14 compress the top plate between the linkage turntables 16. At the same time, the connecting arms 17 are rotationally connected to the tilting load-bearing rods 21. The deflected connecting arms 17 generate an oblique pulling force on the tilting load-bearing rods 21. By allowing the tilting load-bearing rods 21 to swing at the side ends of the reciprocating rack substrates 19, a pulling force is applied to the reciprocating rack substrates 19, causing the reciprocating rack substrates 19 to slide at the top end of the insulating support chassis 13. Through the sliding of the reciprocating rack substrates 19, both ends of the reciprocating rack substrates 19 squeeze or stretch the guiding and resetting rods 22, causing the guiding and resetting rods 22 to expand and contract inside the insulating support chassis 13. By applying a force to the reciprocating rack substrates 19 through the guiding and resetting rods 22, it plays a guiding role in the movement of the reciprocating rack substrates 19; Two driving gear units 18 for docking with the reciprocating rack substrates 19 are rotationally installed at the top end of the insulating support chassis 13. Gear rings are fixedly installed at the ends of the driving gear units 18. Through the sliding of the reciprocating rack substrates 19 at the top end of the insulating support chassis 13, the side ends of the reciprocating rack substrates 19 rub against the surfaces of the driving gear units 18, causing the driving gear units 18 to rotate at the top end of the insulating support chassis 13. The driving gear units 18 are connected to the sliding rotary push rod 26 through transmission rods, and the driving gear units 18 drive the sliding rotary push rod 26 to rotate; Two sealing locking circular plates 23 for sealing connection are fixedly installed at the bottom end of the heat dissipation oil tank 12, and a filter assembly is fixedly installed at the top of each sealing locking circular plate 23. Each filter assembly includes a guide sleeve 31, an oil separation core 32 and a metal retaining ring 33. The top of each guide sleeve 31 is provided with a downward conical groove, and each oil separation core 32 is a multi-layer design. The bottom end of each metal retaining ring 33 is provided with a plurality of drain ports, and the bottom end of each metal retaining ring 33 is connected to the sealing locking circular plate 23. The heat dissipation oil tank 12 stores oil, and the oil enters the interior of the tilting bearing rod 21 through the groove at the top of the guide sleeve 31. The oil flowing in the heat dissipation oil tank 12 is continuously filtered and adsorbed by the oil separation core 32, which can absorb the moisture in the oil, so that the water content of the oil is kept at a low level, thereby improving the electrical performance and stability of the oil. Each sealing locking circular plate 23 is rotatably installed with a sliding push rod 26 that is connected to the guide sleeve 31. The top of each sliding push rod 26 is fixedly installed with a conical sleeve 27 that is connected to the guide sleeve 31. The sealing locking circular plate 23 is moved by the movement of the shell body 11. At the same time, the end of the sliding push rod 26 is fixedly connected to the insulating support frame 13. The sliding push rod 26 can slide inside the sealing locking circular plate 23. At the same time, the conical sleeve 27 and the guide sleeve 31 are in a state of sliding with each other. The oil inside the heat dissipation oil tank 12 is pushed to the inside of the oil-liquid separation core 32 through the conical sleeve 27, thereby accelerating the filtering speed. The surface of each sliding push rod 26 is fixedly installed with a locking connection sleeve 28 for guiding connection, and the surface of each locking connection sleeve 28 is fixedly installed with at least two centering guide sheets 29 for supporting. A closed base 25 is rotatably installed inside each sealing locking circular plate 23, and a rotary blade heat sink 24 that slides with the centering guide sheet 29 is fixedly installed on the top of each closed base 25. When the sliding push rod 26 slides inside the sealing locking circular plate 23, the sliding push rod 26 drives the locking connection sleeve 28 to move synchronously, and at the same time, the centering guide sheet 29 and the rotary blade heat sink 24 are in a docking and sliding role. The rotary blade heat sink 24 is in a stationary state. The advance rod 26 rotates and slides, and the sliding propulsion rod 26 drives the locking connection sleeve 28 to rotate. At the same time, the locking connection sleeve 28 is clamped with the rotary blade heat sink 24 through the centering guide sheet 29. The rotating sliding propulsion rod 26 exerts a force on the rotary blade heat sink 24, so that the closed base 25 drives the rotary blade heat sink 24 to rotate inside the oil separation core 32. The rotational motion makes the flow path of the oil inside the oil separation core 32 more complicated and irregular, which increases the residence time and flow distance of the oil inside the oil separation core 32. The oil has more time to contact the oil separation core 32 and the rotary blade heat sink 24, thereby improving the efficiency of heat transfer and helping to reduce the oil temperature.

[0018] Working principle: First step, a plurality of shock-absorbing struts 14 are installed at the bottom end of the housing body 11 to provide support for the housing body 11. These shock-absorbing struts 14 are spiral-shaped, and a compressible buffer spring 15 is sleeved outside. Moreover, both ends of the shock-absorbing struts 14 are rotatably connected to the linkage rotating seat 16. When the transformer operates and generates vibrations, the housing body 11 will apply pressure to the shock-absorbing struts 14, causing the shock-absorbing struts 14 to rotate and compress inside the linkage rotating seat 16. During this process, the buffer spring 15 is compressed, and the shock-absorbing struts 14 play their shock-absorbing role to initially buffer and absorb the main vibrations generated by the transformer, thereby reducing the energy and amplitude of the vibrations. At the same time, the rubber soft pads on the surface of the linkage rotating seat 16 will secondarily buffer and absorb the vibrations remaining after the initial treatment by the shock-absorbing struts 14. This forms a multi-stage noise reduction structure, effectively reducing the overall noise level during the operation of the transformer.

[0019] On this basis, when the housing body 11 applies pressure to the shock-absorbing struts 14, the compression of the shock-absorbing struts 14 between the linkage rotating seats 16 will cause a change in the rotational connection relationship between the connecting arm 17 and the inclined bearing force rod 21. The deflection of the connecting arm 17 generates an oblique pulling force on the inclined bearing force rod 21. This pulling force will cause the inclined bearing force rod 21 to swing at the side end of the reciprocating rack substrate 19, and then apply a pulling force to the reciprocating rack substrate 19. Since the reciprocating rack substrate 19 slides on the top of the insulating support base frame 13, under the pulling force of the inclined bearing force rod 21, the reciprocating rack substrate 19 begins to slide on the top of the insulating support base frame 13.

[0020] As the reciprocating rack substrate 19 slides, its two ends will squeeze or stretch the guiding and resetting rod 22. The guiding and resetting rod 22 expands and contracts inside the insulating support base frame 13. The expansion and contraction of the guiding and resetting rod 22 play a good guiding role in the movement of the reciprocating rack substrate 19, ensuring its movement within a certain track. Moreover, during the process of the reciprocating rack substrate 19 sliding on the top of the insulating support base frame 13, its side end will generate friction with the surface of the driving gear unit 18. According to the principle of the action of frictional force, this friction will cause the driving gear unit 18 to rotate on the top of the insulating support base frame 13. The driving gear unit 18 is connected to the rotating and sliding type push rod 26 through a transmission rod. Therefore, the rotation of the driving gear unit 18 will transmit power to the rotating and sliding type push rod 26, driving the rotating and sliding type push rod 26 to rotate, thereby converting a part of the vibration energy into rotational power and realizing the conversion and transmission of energy.

[0021] In the second step, due to the movement of the outer shell body 11, the sealing and locking circular plate 23 will also move accordingly. The end of the rotary sliding push rod 26 is fixedly connected to the insulating support base frame 13, enabling the rotary sliding push rod 26 to slide inside the sealing and locking circular plate 23, and the conical sleeve 27 at its top is in a sliding state with the diversion sleeve 31. When the rotary sliding push rod 26 slides, the conical sleeve 27 will push the oil in the heat dissipation oil tank 12 into the oil separation core 32. This pushing effect accelerates the flow of the oil in the oil separation core 32, thereby accelerating the oil filtration speed.

[0022] Meanwhile, the locking connection sleeve 28 mounted on the surface of the rotary sliding push rod 26 is clamped with the rotary vane type heat dissipation frame 24 through the centering guide thin sheet 29. When the rotary sliding push rod 26 rotates, it will exert a force on the rotary vane type heat dissipation frame 24, causing the sealed base 25 to drive the rotary vane type heat dissipation frame 24 to rotate inside the oil separation core 32. The rotation of the rotary vane type heat dissipation frame 24 makes the flow path of the oil inside the oil separation core 32 more complex and irregular, increasing the residence time and flow distance of the oil inside the oil separation core 32. The increase in the residence time and the extension of the flow path of the oil inside the oil separation core 32 allow the oil to have more opportunities to contact the oil separation core 32 and the rotary vane type heat dissipation frame 24. This enables the oil to be more fully filtered and adsorbed of the moisture in it by the oil separation core 32 during the filtration process, maintaining the electrical performance and stability of the oil. Moreover, it can make full use of the contact opportunity with the rotary vane type heat dissipation frame 24 to transfer heat to the rotary vane type heat dissipation frame 24, thereby improving the heat transfer efficiency. Ultimately, it helps to reduce the temperature of the oil, realizing the heat dissipation and filtration functions of the oil, and at the same time ensuring the stable performance and safe operation of the overall transformer.
