Description

Technical Field

[0001] The present invention relates to the technical field of transformer protection, and in particular to a pressure buffer device for a large-capacity oil-immersed transformer. Background Art

[0002] Distribution transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It reduces the 10kV or 35kV network voltage to the 230 / 400V bus voltage used by users. This type of product is suitable for AC 50 (60) Hz, with a maximum three-phase rated capacity of 2500kVA (the maximum single-phase rated capacity is 833kVA, and single-phase transformers are generally not recommended). It can be used indoors (outdoors). When the capacity is 315kVA or below, it can be installed on the pole. The ambient temperature is not higher than 40℃ and not lower than -25℃. The maximum daily average temperature is 30℃, the maximum annual average temperature is 20℃, the relative humidity does not exceed 90% (ambient temperature 25℃), and the altitude does not exceed 1000m. Transformer oil is a petroleum liquid with the possibility of combustion. It has disadvantages in terms of environmental protection. However, due to the excellent performance and low price of transformer oil, the vast majority of power transformers still use transformer oil as insulation and cooling medium.

[0003] At the end of the 19th century, transformers began to use transformer oil as an insulating and cooling medium, and oil-immersed transformers appeared. In addition to its abundant natural reserves and low price, transformer oil has been widely used due to its following characteristics:

[0004] At present, there is too much oil in the large-capacity oil-immersed transformers on the market, resulting in a volume and mass that are larger than ordinary oil-immersed transformers. During the transportation of the transformer, various situations that may cause collisions may occur, such as emergency braking, sharp turns or bumpy roads. In these situations, the transformer will collide with adjacent transformers or other objects under the action of inertia. The impact force of the large-capacity oil-immersed transformer with large mass will also increase proportionally after the collision, causing the large-capacity oil-immersed transformer to be more easily damaged during transportation. Therefore, it is urgent to make a device that can weaken the impact force on the transformer during transportation to protect the large-capacity oil-immersed transformer and prevent the large-capacity oil-immersed transformer from being damaged by collision during transportation.

[0038] The present invention provides a pressure-bearing buffer device for a large-capacity oil-immersed transformer.

[0039] Please refer to Figures 1 to 6The large-capacity oil-immersed transformer pressure buffer device includes a fixing component 2 for fixing the transformer 1, a positioning component 4 for fixing the fixing component 2 on the loading plane is provided below the fixing component 2, and a shock-absorbing buffer component 3 is provided between the positioning component 4 and the fixing component 2;

[0040] The fixing member 2 includes a first carrier plate 21 arranged transversely for supporting the transformer 1. A pressing fixing assembly 22 is slidingly provided on the upper side of the first carrier plate 21 for cooperating with the first carrier plate 21 to clamp the transformer 1.

[0041] The positioning component 4 includes a second supporting plate 41 arranged horizontally below the first supporting plate 21, and the shock-absorbing and buffering component 3 includes at least one supporting column 31 vertically arranged on the side of the second supporting plate 41 close to the first supporting plate 21. A receiving cavity 31a for receiving a buffer liquid is formed in the supporting column 31, and a plate 32 sliding along the extension direction of the supporting column 31 is provided in the receiving cavity 31a. Elastic components 36 are respectively provided on both sides of the sliding direction of the plate 32. A sliding hole connected to the receiving cavity 31a is formed on the side of the supporting column 31 away from the second supporting plate 41. A supporting slide rod 33 is provided for sliding, and a connecting plate 35 is provided at one end of the supporting column 31 facing away from the second supporting plate 41. The connecting plate 35 is fixed to the side of the first supporting plate 21 close to the second supporting plate 41. One end of the supporting slide rod 33 is located in the receiving cavity 31a, and the other end is connected to the connecting plate 35. The end of the supporting slide rod 33 located in the receiving cavity 31a is provided with a penetrating abutment plate 32, which is used to allow the liquid in the receiving cavity 31a to pass through and slow down the flow rate of the liquid. The four corners of the first supporting plate 21 and the second supporting plate 41 are respectively provided with guide members 37 for limiting the movement direction of the first supporting plate 21.

[0042] In the technical solution of the present invention, the outer wall of the receiving chamber 31a near the support plate 32 is replaced by a first sealing ring that contacts the receiving chamber 31a, and the wall of the sliding hole is surrounded by a second sealing ring that contacts the supporting slide rod 33. The first sealing ring is used to allow the liquid to flow to the other side of the support plate 32 only through the buffer block 34, and the second sealing ring is used to prevent the liquid in the receiving chamber 31a from flowing out of the sliding hole. The buffer block 34 is used to slow down the flow rate of the liquid, thereby achieving the effect of slowing down the movement of the support plate 32. The elastic component 36 is a compression spring 434, which is used to buffer the downward pressure of the first supporting plate 21. Because the transformer 1 is fixed to the first supporting plate 21 by the downward pressing fixing component 22, when the transformer 1 is subjected to upward inertia, the transformer 1 drives the first supporting plate 21 toward away from the second supporting plate 41 The support rod 33 is moved to one side, and at the same time, the supporting slide bar 33 is driven to slide toward the side away from the supporting column 31 through the connecting plate 35. When the supporting slide bar 33 slides, the buffer block 34 and the push plate 32 are moved together, and the push plate 32 squeezes the liquid in the receiving chamber 31a, so that the liquid enters the other side of the push plate 32 through the buffer block 34. The same is true when the supporting slide bar 33 descends, and this is repeated to unload the inertia of the transformer 1 to buffer the transformer 1. The guide member 37 cooperates with the downward fixing assembly 22 to prevent the transformer 1 from tipping over due to the inertia of the left and right movement. Through the mutual cooperation between the above structures, the transformer 1 can be fixed on the carrying equipment and prevented from being damaged by the impact due to the force of inertia during transportation.

[0043] Please refer to the attached Figure 2 The buffer block 34 is formed with a plurality of first liquid holes 34a and a plurality of second liquid holes 34b near the top. One end of the first liquid hole 34a is located on the side of the support plate 32 away from the support slide 33, and the other end is located on the side of the support plate 32 close to the support slide 33. The diameter of the first liquid hole 34a gradually decreases toward the side of the support plate 32 away from the support slide 33.

[0044] One end of the second liquid hole 34b is located on the side of the support plate 32 away from the support slide 33, and the other end is located on the side of the support plate 32 close to the support slide 33. The diameter of the second liquid hole 34b gradually increases toward the side of the support plate 32 away from the support slide 33.

[0045] A first one-way valve is provided at the gradually smaller opening of the first liquid hole 34a, for liquid to flow from the large hole of the first liquid hole 34a into and out of the small hole;

[0046] A second one-way valve is installed at the gradually enlarging opening of the second liquid hole 34b, allowing liquid to flow from the larger opening of the first liquid hole 34a into the smaller opening. As the liquid flow path gradually narrows, the liquid pressure increases, while the liquid flow rate decreases, increasing the time it takes for the liquid to pass through. Since increasing liquid pressure consumes energy, it reduces the inertial force acting on the transformer 1. The one-way valve ensures unidirectional flow of liquid through the first and second liquid holes 34a, 34b, preventing liquid from flowing through both holes simultaneously, thereby increasing the pressure of the circulating liquid.

[0047] Please refer to the attached Figure 1 , mounting plates 45 are symmetrically provided on both sides of the second carrying plate 41, and two box fixing components 42 are distributed on both sides above the mounting plate 45. The box fixing components 42 are used to match and fix the second carrying plate 41 to the top wall of the container truck;

[0048] Two corners of the mounting plate 45 facing away from the second carrier plate 41 are provided with flatbed fixing assemblies 44, which are used to secure the second carrier plate 41 to the flatbed of the flatbed truck. The second carrier plate 41 can be placed in the container truck's box using the box fixing assemblies 42, securing it there and preventing it from moving during transport. The second carrier plate 41 can also be placed on the flatbed of the flatbed truck using the flatbed fixing assemblies 44, securing it there and preventing it from moving during transport.

[0049] Please refer to the attached Figure 1 and 3 The box fixing assembly 42 includes a vertical locking assembly 43 arranged on the upper side of the mounting plate 45. A threaded rod 422 is provided on the side of the vertical locking assembly 43 away from the mounting plate 45. The outer wall of the end of the threaded rod 422 away from the vertical locking assembly 43 is threadedly engaged with a support rod 421, and the end of the support rod 421 away from the threaded rod 422 is rotatably connected to the top plate 423. The vertical locking assembly 43 is used to enable the threaded rod 422 to be tilted and placed on the mounting plate 45 and perpendicular to the mounting plate 45. When the second supporting plate 41 needs to be fixed in the box body of the container truck, the threaded rod 422 is rotated and erected, and then the threaded rod 422 is vertically fixed by the vertical locking assembly 43, and then the support rod 421 is rotated so that the support rod 421 moves away from the threaded rod 422, thereby making the top plate 423 close to the top wall of the box body, and further making the top plate 423 conflict with the top of the box to achieve the fixation of the second supporting plate 41, and the side of the top plate 423 away from the support rod 421 is provided with an anti-slip layer.

[0050] Please refer to the attached Figure 3The vertical locking assembly 43 includes a fixing block 431 vertically arranged on the upper side of the mounting plate 45, and the fixing block 431 is rotatably connected to the convex plates 435 on both sides. The two convex plates 435 are connected by a positioning block 432 on one side. The side of the positioning block 432 away from the convex plate 435 is used to connect the end of the threaded rod 422 away from the support rod 421. The side of the fixing block 431 away from the mounting plate 45 is recessed to form a first plug hole 431a. The positioning block 432 away from the threaded rod 422 is A recessed receiving hole 432a is formed on one side of the housing. A first rod 433 is received within the receiving hole 432a, which is capable of being inserted into the first insertion hole 431a. A spring 434 is provided on the side of the first rod 433 near the bottom of the receiving hole 432a. A first through-slot 432b is formed transversely through the receiving hole 432a. A lever is slidably disposed within the first through-slot 432b. One end of the lever is connected to the outer wall of the first rod 433, and the other end extends beyond the first through-slot 432b. After the first rod 433 is inserted into the first insertion hole 431a, the threaded rod 422 remains upright and fixed. Pulling the lever moves the first rod 433 toward the bottom of the receiving hole 432a, disengaging the first rod 433 from the first insertion hole 431a. At this point, the threaded rod 422 can rotate about the rotation axis of the protruding plate 435, placing the threaded rod 422 on the mounting plate 45, thereby storing the box fixing assembly 42.

[0051] Please refer to the attached Figure 1 and 4 The tablet fixing assembly 44 includes a storage box 441 located at a top corner of the mounting plate 45 facing away from the second carrier plate 41. A tightener 442 for tightening a rope 443 is fixed within the storage box 441. The tightener 442 is attached to the rope 443. An opening 441a is formed on the side of the storage box 441 facing away from the mounting plate 45, through which the rope 443 extends. A hook 444 is provided on the end of the rope 443 facing away from the tightener 442. Because two mounting plates 45 are provided on either side of the second carrier plate 41, four tablet fixing assemblies 44 are provided. These can be used to tighten the second carrier plate 41 at its four corners, thereby securing the second carrier plate 41.

[0052] Please refer to the attached Figure 1 and 5-6. Two receiving grooves 225 extending in the same direction are formed on the side of the first supporting plate 21 away from the second supporting plate 41. A cross bar 226 is provided in each of the receiving grooves 225. The downward pressing and fixing components 22 are provided with two groups. The downward pressing and fixing components 22 include a slider 221 slidably set on each cross bar 226. A vertical bar 222 is vertically provided on the outer wall of each slider 221. The two vertical bars 222 are connected by a horizontally set pressure bar, and the two ends of the pressure bar are slidably connected to the vertical bar 222 through a sliding positioning member 224. During use, the transformer 1 is placed on the upper side of the first supporting plate 21, and then the two groups of sliders 221 on the downward pressing fixing assembly 22 are used to make the pressure rod located above the transformer 1. The position of the pressure rod is then moved so that the pressure rod is pressed against the upper side of the transformer 1, and the position of the pressure rod is fixed by the sliding positioning member 224 to achieve downward pressure on the transformer 1 to prevent the transformer 1 from tipping over after being subjected to the force of inertia. The upper side of the first supporting plate 21 and the lower side of the second supporting plate 41 are respectively provided with anti-slip layers, and the outer wall of the pressure rod is wrapped with a flexible layer to prevent the pressure rod from being damaged by hard friction with the transformer 1.

When it is necessary to locate the position of the slide 2241, the positioning rod 2242 is inserted through the outer wall of the slide 2241 into the installation cavity 222a, and the block 2244 is inserted into the slot, thereby fixing the slide 2241. The positioning pin 2243 can prevent the positioning rod 2242 from being separated from the slot after the block 2244 is separated from the slot. Only after the block 2244 is inserted into the slot can the positioning pin 2243 pass through the slide 2241 and the positioning rod 2242 at the same time.

[0054] Please refer to the attached Figure 6The crossbar 226 is recessed at intervals to form second insertion holes 226a. The slider 221 is provided with second insertion rods 227 that vertically penetrate the slider 221 and are inserted into the second insertion holes 226a. The second insertion rods 227 cooperate with the second insertion holes 226a to fix the position of the slider 221, thereby fixing the position of the vertical rod 222.
