Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of transformer operation supporting equipment of power transmission and transformation system, particularly relates to a transformer damping device. BACKGROUND

[0002] The transformer produces certain noise in the operation process, and most of the transformer noise is not high-decibel strong noise, but low-frequency noise. The low-frequency noise produced by the transformer in most cases can cause chronic damage to the human body, easily making people irritable, sometimes even losing reason, and long-term harassment can also cause neurasthenia, insomnia and other nervous diseases.

[0003] Under normal circumstances, the source of the noise produced by the transformer is the vibration caused by the magnetic strain of the transformer core inside and the vibration caused by the electromagnetic force of the winding, and the vibration of the busbar caused by the change of the current through the busbar.

[0004] Under normal circumstances, the vibration noise of the transformer mainly appears at 50Hz and its multiples, and such low-frequency noise has the characteristics of strong penetration and slow attenuation, mainly propagating through two ways of air conduction and structure conduction. The noise propagating through the air can be well reduced by sound-absorbing cotton and other sound-absorbing measures, but the vibration and noise propagating through the structure are difficult to be damped and reduced by sound-absorbing cotton and other materials, and in the building structure, such vibration can be transmitted to a very high floor along the floor, wall and other building structures.

[0005] In many old communities, the transformer room is usually located on the first floor of the residential building, and the busbars at the high and low voltage ends of the transformer are fixed on the wall of the transformer room by bolts. The vibration produced by the transformer is directly transmitted to the wall through the busbar, and then to the residents' homes on the upper floors, causing noise problems and affecting the residents' rest.

[0006] In order to solve the problem of vibration and noise transmission through the busbar, the current mainstream measure is to change the connection between the transformer and the busbar to elastic soft connection. However, by changing to soft connection, on the one hand, only a part of the vibration can be reduced, and still a lot of vibration is transmitted to the wall through the elastic material; on the other hand, the material used for elastic connection may have a low service life under the action of electric field and electromagnetic force, and is prone to failure. At the same time, the current main measure is to take single-layer vibration isolation for damping, which has low isolation rate and poor low-frequency isolation effect.

[0007] Therefore, how to optimize the structure of the damping device matched with the transformer and improve the damping treatment effect of the transformer is an important technical problem to be solved by those skilled in the art. UTILITY MODEL CONTENT

[0044] Please refer to Figures 1 to 4 .

[0045] In the specific embodiment, the transformer damping device provided by the utility model comprises a damping seat 10 horizontally arranged at the bottom of a transformer 20, a plurality of vibration isolators 101 capable of cooperating with the transformer 20 are arranged on the damping seat 10, a plurality of damping cavities 102 are further arranged in the damping seat 10, and a plurality of damping particles 103 are contained in the damping cavities 102.

[0046] In the specific operation process, during installation and use, the damping seat 10 is horizontally placed on a ground or a cement platform or other foundation bearing structure, and then the transformer 20 is reliably placed on the damping seat 10, so that the damping seat 10 reliably supports and supports the transformer 20 in place.

[0047] Generally, the damping seat 10 can be reliably fixed to the ground or the cement platform or other foundation bearing structure by means of bolts, and the damping seat 10 and the transformer 20 located above the damping seat 10 can be reliably connected by means of bolts. Of course, considering the installation conditions of some special working conditions, the transformer 20 can also be directly and stably placed on the damping seat 10 under the premise of ensuring the stable installation of the main structure of the damping seat 10, without the need for auxiliary connecting members such as bolts to ensure the direct connection and assembly of the transformer 20 and the damping seat 10. In actual application, the staff can flexibly select and adjust the specific assembly mode of the transformer damping device and the transformer 20 according to the actual working condition demand and equipment installation arrangement condition, and in principle, as long as the reliable placement of the transformer 20 and the transformer damping device can be ensured, and the stable installation and operation of the transformer 20 can be met.

[0048] During the subsequent operation of the transformer 20, the structural vibration caused by the operation of the transformer 20 can be conducted to the damping particles 103 in the damping cavity 102, so as to effectively consume the energy conducted by the structural vibration through the inelastic collision and friction between the damping particles 103 and between the damping particles 103 and the inner wall of the damping cavity 102, thereby effectively reducing the vibration transmitted to the building main structure such as the wall by the busbar and other components during the operation of the transformer 20; at the same time, the vibration isolators 101 installed at different positions of the damping seat 10 are cooperated to further reduce the structural vibration conducted to the adjacent component structure during the operation of the transformer 20, so as to greatly improve the vibration isolation rate of the transformer 20 during the operation of the transformer 20 by using the transformer damping device, optimize the vibration isolation effect of the low-frequency vibration generated during the operation of the transformer 20, and accordingly weaken and eliminate the low-frequency noise caused by the operation of the transformer 20, thereby making the overall operation of the transformer 20 more quiet and stable, and having less impact on the noise and vibration of the surrounding working environment.

[0049] Further, the damping seat 10 comprises a first-stage damping frame and a second-stage damping frame arranged in sequence from bottom to top, and the second-stage damping frame is overlapped on the top of the first-stage damping frame and is adapted to the transformer 20, and the damping cavity 102 is arranged in the first-stage damping frame and the second-stage damping frame.

[0050] During the assembly of the components, the first-stage damping frame is first reliably installed on the ground or a cement platform or other foundation bearing structure, and then the second-stage damping frame is overlapped on the first-stage damping frame and is reliably fastened in place, and then the transformer 20 is reliably installed on the second-stage damping frame, so that the second-stage damping frame serves as an adapted component directly connected to the transformer 20, and the first-stage damping frame serves as a foundation bearing component in the structure of the transformer damping device.

[0051] During the operation of the transformer 20, the first-stage damping frame and the second-stage damping frame are cooperated to form a double-stage damping mechanism, so as to further improve the vibration isolation rate of the transformer damping device to the structural vibration generated during the operation of the transformer 20, optimize the vibration isolation effect, and further reduce the conduction of the low-frequency vibration and the low-frequency noise generated during the operation of the transformer 20.

[0052] Specifically, the first damping frame comprises at least two first damping beams 11 arranged in parallel, the second damping frame comprises at least two second damping beams 12 arranged in parallel, the length direction of the first damping beams 11 is perpendicular to the length direction of the second damping beams 12, and the end of the second damping beams 12 is overlapped on the end of the first damping beams 11. In this way, each first damping beam 11 cooperates with each second damping beam 12, so that the damping seat 10 forms a substantially quadrilateral assembly structure. Referring to the horizontal projection of the damping seat 10, the horizontal projection of the damping seat 10 is a rectangle, wherein the horizontal projection of the two first damping beams 11 constitutes one pair of opposite sides of the rectangle, and the horizontal projection of the two second damping beams 12 constitutes the other pair of opposite sides of the rectangle. In this way, the main assembly position and the force transmission position between the first damping frame and the second damping frame are located at the ends of the damping beams, which is beneficial to the overall stress distribution of the damping seat 10. In combination with the vibration isolator 101 arranged below the ends of the damping beams, the structural vibration transmitted from the transformer 20 to the damping seat 10 can be better relieved and eliminated, so as to further optimize the vibration isolation effect of the transformer damping device on the transformer 20 during operation, and make the transformer 20 work more stably and quietly.

[0053] In actual application, in order to further improve the structural strength of the damping seat 10, a horizontal reinforcing beam 14 can be arranged horizontally between the two first damping beams 11, the length direction of the horizontal reinforcing beam 14 is consistent with the length direction of the second damping beam 12, and the two ends of the horizontal reinforcing beam 14 are respectively welded and fixed on the side walls of the two first damping beams 11.

[0054] Further, the first damping beam 11 comprises at least one first damping module 110 arranged along the length direction of the first damping beam 11, and the second damping beam 12 comprises at least two second damping modules 120 arranged in sequence along the length direction of the second damping beam 12. Further, the first damping beam 11 can also comprise at least two first damping modules 110 arranged in sequence along the length direction of the first damping beam 11. In this way, based on the double-stage damping structure layout of the first damping frame and the second damping frame, an array arrangement structure formed by the cooperation of the plurality of first damping modules 110 and the plurality of second damping modules 120 can be formed, so as to further optimize the stability of the damping support structure of the transformer damping device at each position of the bottom of the transformer, and the damping adaptation structure layout of the transformer damping device and the transformer and the damping treatment effect thereof can be correspondingly optimized.

[0055] On this basis, the end of the first damping module 110 is provided with an adapter frame 13 capable of supporting the end of the second damping module 120, and the end of the second damping module 120 is connected to the adapter frame 13 through a fastening bolt penetrating the adapter frame 13. Generally, the adapter frame 13 is a plate-shaped member capable of serving as a supporting platform for supporting the end of the second damping module 120 and reliably assembling with the end of the second damping module 120. The adapter frame 13 is arranged above the end of the first damping module 110 and is adapted to the end of the second damping module 120, that is, the adapter frame 13 is located between the end of the second damping module 120 and the end of the first damping module 110 in the vertical direction.

[0056] More specifically, the end of the second damping module 120 is provided with a lap plate 121 protruding along the length direction thereof, a waist-shaped hole 122 penetrating the lap plate 121, and the long axis of the waist-shaped hole 122 extending along the length direction of the second damping beam 12. A fastening bolt is correspondingly inserted into the waist-shaped hole 122. Generally, the fastening bolt penetrates the waist-shaped hole 122 and the top supporting platform 131 in sequence from top to bottom in the vertical direction, or the fastening bolt penetrates the top supporting platform 131 and the waist-shaped hole 122 in sequence from bottom to top in the vertical direction. Thus, after the fastening bolt is reliably connected with the adapter frame 13 and assembled in linkage, the relative positional relationship between the second damping module 120 and the adapter frame 13 can be adjusted by adjusting the movement of the fastening bolt along the long axis direction of the waist-shaped hole 122. On this basis, in combination with the linkage assembly structure between the adapter frame 13 and the first damping module 110, the adjustment of the relative assembly position between the second damping module 120 and the first damping module 110 can be realized, and further the flexible adjustment of the overall structural layout, shape, size and other specific structural specifications of the damping seat 10 can be realized to match the installation and adaptation requirements of transformers 20 of different sizes.

[0057] It should be noted that the length direction of the first damping module 110 is consistent with the length direction of the first damping beam 11 where the first damping module 110 is located, and the length direction of the second damping module 120 is consistent with the length direction of the second damping frame 12 where the second damping module 120 is located.

[0058] It is not difficult to understand that a horizontally extended auxiliary connecting plate can also be arranged at the end of the first damping module 110 to ensure the reliable assembly between the adapter frame 13 and the first damping module 110 through the linkage assembly between the auxiliary connecting plate and the adapter frame 13 by means of the fastening bolt. Of course, the adapter frame 13 can also be directly assembled on the main structure of the first damping module 110 through the fastening bolt. The staff can flexibly adjust and select the specific assembly form between the adapter frame 13 and the first damping module 110 according to the actual working conditions and assembly application requirements. In principle, as long as it can meet the actual application needs of the transformer damping device, it is acceptable.

[0059] In addition, at least two damping cavities 102 are arranged in the primary damping module 110, at least two damping cavities 102 are arranged in the secondary damping module 120, and the diameters of the damping particles 103 in any two adjacent damping cavities 102 are different. In this way, the adjacent multiple damping cavities 102 have different vibration energy consumption effects, so that the performance differences of the multiple damping cavities 102 are combined to achieve efficient vibration isolation and damping treatment of the structural vibration generated during the operation of the transformer 20, further optimize the vibration isolation treatment effect of the transformer damping device, and the low-frequency noise generated during the operation of the transformer 20 is correspondingly weakened and eliminated.

[0060] For the above-mentioned array arrangement structure composed of multiple primary damping modules 110 and multiple secondary damping modules 120 in cooperation, the assembly structure layout of Figures 5 to 8 can be correspondingly understood.

[0061] For example, as shown in Figure 5 and Figure 6 , three primary damping beams 11 and two secondary damping beams 12 are cooperated, each primary damping beam 11 includes one primary damping module 110, and each primary damping beam 11 is arranged in parallel and gap cooperated in turn, and each secondary damping beam 12 includes two secondary damping modules 120, and the two secondary damping modules 120 in the same secondary damping beam 12 are arranged in sequence along the length direction of the secondary damping beam 12, so that the assembly structure layout of 3 primary damping modules 110 and 4 secondary damping modules 120 is arranged and assembled in array.

[0062] For example, as shown in Figure 7 and Figure 8 , three primary damping beams 11 and three secondary damping beams 12 are cooperated, each primary damping beam 11 includes two primary damping modules 110, and the two primary damping modules 110 in the same primary damping beam 11 are arranged in sequence along the length direction of the primary damping beam 11, and each secondary damping beam 12 includes two secondary damping modules 120, and the two secondary damping modules 120 in the same secondary damping beam 12 are arranged in sequence along the length direction of the secondary damping beam 12, so that the assembly structure layout of 6 primary damping modules 110 and 6 secondary damping modules 120 is arranged and assembled in array.

[0063] Of course, the above-mentioned Figures 5 to 8The array layout of the first damping module 110 and the second damping module 120 shown is only for illustration, in actual application, the staff can flexibly select and adjust the specific number and array arrangement mode of the first damping module 110 and the second damping module 120 according to the specific working condition requirements, and the structure layout of the adapter frame 13 and other supporting components can also be adaptively adjusted according to the specific number and layout mode of the first damping module 110 and the second damping module 120. In principle, as long as it can meet the actual application needs of the transformer damping device.

[0064] Generally, the surface friction factor of the damping particles 103 contained in the damping cavity 102 is 0.01-0.99, the surface recovery coefficient is 0.01-1, and the density is 0.1-30 g / cm 3 The filling rate of the damping particles 103 in any damping cavity 102 is 60%-90%, which can meet the vibration isolation and damping processing needs under most working conditions. Of course, the performance parameters of the damping particles 103 are not limited to this, and the specific performance parameters of the damping particles 103 can be flexibly selected and adjusted for some special working conditions to meet the vibration isolation application needs under different working conditions.

[0065] It should be noted that the damping particles 103 are generally at least one of metal, inorganic non-metal, and organic polymer particles, more specifically, at least one of iron-based particles, ceramic particles, aluminum-based particles, TPU particles, and POM particles. Of course, other materials can also be selected, but attention should be paid to ensure that the damping particles 103 have basic structural strength and wear resistance and other working condition resistance to ensure that the damping cavity 102 and its supporting damping particles 103 are more durable and have more stable and reliable performance, and the overall stability and durability of the transformer damping device are correspondingly optimized.

[0066] On the other hand, the vibration isolators 101 are correspondingly arranged below the end of each first damping module 110 of the first damping beam 11 and at the position on the second damping beam 12 that is directly adapted to the end of the transformer 20. In this way, the vibration isolators 101 located below the end of each first damping module 110 of the first damping beam 11 can cooperate with the vibration isolators 101 located on the second damping beam 12 that are directly adapted to the transformer 20 to form a double-stage vibration isolator 101 layout structure, thereby further optimizing the double-stage damping assembly structure composed of the first damping frame and the second damping frame, further optimizing the component structure layout of the damping seat 10, and further improving the overall vibration isolation performance of the transformer damping device.

[0067] On this basis, the vibration isolator 101 is arranged corresponding to the end of each primary damping module 110 of the primary damping beam 11 and the position on the secondary damping beam 12 that can be matched with the transformer 20, which can further ensure the structural matching effect of the vibration isolator 101 and each main vibration conduction position in the main structure of the transformer damping device, so that the corresponding vibration damping effect is optimal, so that the vibration damping effect of the transformer damping device in the operation of the transformer 20 is better.

[0068] It is not difficult to understand that the parameters of the damping particles and the specific selection of each vibration isolator in the scheme need to be determined according to the vibration amplitude and frequency of the transformer to be damped.

[0069] Correspondingly, the vibration isolator 101 can be at least one of a spring vibration isolator, a rubber vibration isolator, an air spring vibration isolator, a steel wire rope vibration isolator, a metamaterial vibration isolator or a spring rubber composite vibration isolator. Of course, in actual assembly application, the specific type of the vibration isolator 101 can be flexibly selected and adjusted according to the specific working condition requirements, but for the type selection of the vibration isolator 101, the structural adaptability of the vibration isolator 101 to each main component of the transformer damping device should be ensured first, and the specific application requirements of the transformer type under the current working condition should be met to ensure the adaptive connection effect of the transformer damping device and the transformer 20.

[0070] As can be seen from the above, in the installation and use process of the transformer damping device provided in the utility model, the damping seat is placed horizontally on the ground or a cement platform or other foundation bearing structure, and then the transformer is reliably placed on the damping seat, so that the damping seat reliably supports and supports the transformer in place. During the subsequent operation of the transformer, the structural vibration caused by the operation of the transformer will be transmitted to the damping particles in the damping cavity, so as to effectively consume the energy transmitted by the structural vibration through the inelastic collision and friction between the damping particles and the inner wall of the damping cavity, thereby effectively reducing the vibration transmitted to the wall or other building main structure by the busbar and other components during the operation of the transformer. At the same time, the vibration isolators installed at different positions of the damping seat are cooperated to further reduce the structural vibration transmitted to the adjacent component structure during the operation of the transformer, so as to greatly improve the vibration isolation rate of the transformer during the operation of the transformer, optimize the vibration isolation effect of the low-frequency vibration generated during the operation of the transformer, and accordingly weaken and eliminate the low-frequency noise caused by the operation of the transformer. Thus, the overall operation of the transformer is more quiet and stable, and the noise and vibration impact on the surrounding working environment is smaller.

[0071] The above has carried out the detailed introduction to the transformer damping device provided by the utility model. The principle and implementation mode of the utility model are described by applying specific examples in this paper, and the above embodiment description is only used for helping to understand the method and core idea of the utility model. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claim.
