Transformer box structure

Abstract

The present application relates to a transformer box structure, including a flexible shell and a bracket. An installation cavity is formed in the flexible shell, and the installation cavity is used to install a transformer. The flexible shell has an expanded state that expands the installation cavity and a folded state that shrinks the installation cavity. The bracket is arranged in the installation cavity, and the bracket has an extended state and a retracted state. In the extended state, the bracket can support the flexible shell so that the flexible shell is maintained in the expanded state. In the retracted state, the flexible shell can shrink and fold to the folded state. In the transformer box structure of the present application, when the bracket is in the extended state, the flexible shell can maintain a certain electrical distance from the live parts of the transformer arranged therein. When the bracket is in the retracted state, the flexible shell can reduce the volume of the transformer box structure by bending and folding, so that the transformer product can be transported as a whole to the power distribution room, thereby saving costs during transportation and avoiding problems caused by secondary assembly.

Description

Technical Field

[0001] The present application relates to the technical field of transformers, and in particular to a transformer box structure. Background Art

[0002] Generally, in order to prevent foreign objects from entering and ensure the safety of operators, transformers need to be equipped with boxes. Transformer products equipped with boxes are usually assembled first and then packaged and transported to the power distribution room for power supply.

[0003] Since there should be a certain electrical distance between the box and the live parts of the transformer, the overall volume of the transformer will become larger after the assembly of the box and the transformer. This will lead to problems such as insufficient capacity of the transport vehicle and too narrow aisles during the transportation of the transformer products, which will result in the need to dismantle the box and secondary wiring materials before the transformer products can be transported to the site. After the transformer products are transported to the site, they still need to be reassembled before they can be used. This not only increases the manpower and material costs of the transportation process, but also easily causes unnecessary damage to the products. Summary of the invention

[0004] Based on this, it is necessary to provide a transformer box structure that can adjust the overall volume of the transformer product to address the above-mentioned problems, so that the transformer product can adapt to smaller vehicles or containers during transportation, and can adaptively adjust the volume according to the size of the distribution room door or aisle.

[0005] The technical solution is as follows:

[0006] On the one hand, a transformer box structure is provided, comprising:

[0007] A flexible shell, wherein a mounting cavity is formed in the flexible shell, the mounting cavity is used to mount a transformer, and the flexible shell has an unfolded state in which the mounting cavity is expanded and a folded state in which the mounting cavity is reduced;

[0008] The bracket is arranged in the installation cavity, and the bracket has an extended state and a retracted state. In the extended state, the bracket can support the flexible shell so that the flexible shell is maintained in the expanded state. In the retracted state, the flexible shell can be contracted and folded to the folded state.

[0009] In the above transformer box structure, since the volume of the installation cavity is larger when the flexible shell is in the expanded state, and the volume of the installation cavity is smaller when the flexible shell is in the folded state, and when the bracket is in the extended state, the bracket can keep the flexible shell in the expanded state, and when the bracket is in the retracted state, the flexible shell can shrink and fold, so in the process of transporting the transformer product with the transformer box structure, when the transport vehicle volume is insufficient and the channel is too narrow, the bracket can be switched to the retracted state, so that the flexible shell can reduce the volume of the transformer box structure by bending and folding, so that the transformer product can be conveniently transported to the power distribution room without disassembling the transformer product, thereby effectively saving the manpower cost and material cost in the transportation process, and effectively avoiding the problems caused by secondary assembly. When the transformer product is transported to the power distribution room, it only needs to switch the bracket to the extended state, that is, the flexible shell can be maintained in a larger expanded state, so that the flexible shell can maintain a certain electrical distance from the live part of the transformer arranged inside it, so as to ensure that the transformer box structure can achieve corresponding protection performance during the operation of the transformer. Therefore, the transformer box structure can adaptively adjust the overall size of the transformer box structure according to actual needs, so that the transformer product can be conveniently transported.

[0042] Combination Figure 1 , Figure 2 and Figure 3 As shown, a transformer box structure 100 provided in one embodiment of the present application includes a flexible shell 1 and a bracket 3. An installation cavity 1b is formed in the flexible shell 1. The installation cavity 1b is used to install the transformer 200. The flexible shell 1 has an expanded state that expands the installation cavity 1b and a folded state that shrinks the installation cavity 1b. The bracket 3 is arranged in the installation cavity 1b. The bracket 3 has an extended state and a retracted state. In the extended state, the bracket 3 can support the flexible shell 1 so that the flexible shell 1 is maintained in the expanded state. In the retracted state, the flexible shell 1 can be folded to the folded state.

[0043] In the above-mentioned transformer box structure 100, since the volume of the installation cavity 1b is larger when the flexible shell 1 is in the expanded state, and the volume of the installation cavity 1b is smaller when the flexible shell 1 is in the folded state, and when the bracket 3 is in the extended state, the bracket 3 can maintain the flexible shell 1 in the expanded state, and when the bracket 3 is in the retracted state, the flexible shell 1 can be shrunk and folded to the folded state, so in the process of transporting the transformer product with the transformer box structure 100, when the volume of the transport vehicle is insufficient and the channel is too narrow, the bracket 3 can be switched to the retracted state, so that the flexible shell 1 can reduce the volume of the transformer box structure 100 by bending and folding, so that the transformer product can be conveniently transported to the distribution room without disassembling the transformer product, thereby effectively saving the manpower cost and material cost during the transportation process, and can also effectively avoid the problems caused by secondary assembly. When the transformer product is transported to the power distribution room, it is only necessary to switch the bracket 3 to the extended state, so that the flexible housing 1 can be maintained in a larger expanded state, and the flexible housing 1 can maintain a certain electrical distance from the live parts of the transformer 200 disposed therein, thereby ensuring that the transformer box structure 100 can achieve corresponding protection performance during the operation of the transformer 200. Therefore, the transformer box structure 100 can adaptively adjust the overall size of the transformer box structure 100 according to actual needs, so that the transformer product can be conveniently transported.

[0044] Optionally, when the bracket 3 is in an extended state supporting the flexible housing 1, the bracket 3 can tighten the side wall of the installation cavity 1b by means of a restrictive cooperation with the flexible housing 1, so that the flexible housing 1 can be in an expanded state with the largest volume of the installation cavity 1b, thereby ensuring that the flexible housing 1 can maintain a certain electrical distance from the live parts of the transformer 200 to meet safety requirements, such as in combination with Figure 1 and Figure 3 When the bracket 3 switches from the extended state to the retracted state, the flexible shell 1 cannot be maintained in the extended state due to the failure of the restraining fit between the bracket 3 and the flexible shell 1, so that the part of the flexible shell 1 that loses the restraint can bend and fold toward the gathering side to reduce the volume of the flexible shell 1, as shown in FIG. Figure 2 shown.

[0045] Optionally, the bracket 3 can be used to connect with the transformer 200 .

[0046] In one embodiment, in combination Figure 3 and Figure 4As shown, the bracket 3 includes a first support frame 31, a first telescopic rod 32, a second support frame 33 and a second telescopic rod 34. The first support frame 31 and the second support frame 33 are used to be arranged on opposite sides of the transformer 200 respectively. The first telescopic rod 32 includes a first connecting portion 321 and a first sliding portion 322. One end of the first connecting portion 321 is connected to the first support frame 31, and the other end is slidably connected to the first sliding portion 322. The second telescopic rod 34 includes a second connecting portion 341 and a second sliding portion 342. One end of the second connecting portion 341 is connected to the second support frame 32, and the other end is slidably connected to the second sliding portion 342. The first telescopic rod 32 and the second telescopic rod 34 are arranged opposite to each other. The first sliding portion 322 can move closer to or farther from the first support frame 31 along the extension direction of the first connecting portion 321 relative to the first connecting portion 321, and the second sliding portion 342 can move closer to or farther from the second support frame 33 along the extension direction of the second connecting portion 341 relative to the second connecting portion 341. In the extended state, the first sliding portion 322 extends relative to the first connecting portion 321 to a side away from the first support frame 31, and the second sliding portion 342 extends relative to the second connecting portion 341 to a side away from the second support frame 33. In the retracted state, the first sliding portion 322 retracts relative to the first connecting portion 321 to a side close to the first support frame 31, and the second sliding portion 342 retracts relative to the first connecting portion 341 to a side close to the second support frame 33. In this way, the bracket 3 can be switched from the extended state to the retracted state by only sliding the first telescopic rod 32 relative to the first connecting portion 321 to a side close to the first support frame 31, and sliding the second telescopic rod 34 relative to the second connecting portion 341 to a side close to the second support frame 33, so that the flexible shell 1 can be contracted and folded, thereby effectively reducing the length of the flexible shell 1 in the extension direction of the first connecting rod 321, thereby conveniently reducing the volume of the transformer box structure 100. When the bracket 3 is in the retracted state, the flexible shell 1 can be switched to the expanded state by sliding the first sliding part 322 to the side away from the first support frame 31 and sliding the second sliding part 342 to the side away from the second support frame 32, so that the transformer 200 product can be maintained in a larger expanded state after being transported to the site, so as to ensure that the flexible shell 1 and the live parts of the transformer 200 can have a certain electrical distance.

[0047] Optionally, a nesting cavity extending axially thereof is formed at the end of the first connecting portion 321, and the first sliding portion 322 can be slidably nested in the nesting cavity of the first connecting portion 321. In this way, when the first sliding portion 322 slides relative to the first connecting portion 321, the first connecting portion 321 can guide the first sliding portion 322, thereby facilitating ensuring the reliability of the structure.

[0048] Optionally, a nesting cavity extending axially thereof is formed at the end of the second connecting portion 341, and the second sliding portion 342 can be slidably nested in the nesting cavity of the second connecting portion 341. In this way, when the second sliding portion 342 slides relative to the second connecting portion 341, the second connecting portion 341 can guide the second sliding portion 342, thereby facilitating ensuring the reliability of the structure.

[0049] Optionally, the first support frame 31 and the second support frame 32 are respectively connected to opposite sides of the transformer 200. Specifically, the first support frame 31 can be used to connect with the first clamp 210 in the transformer 200, and the second support frame 33 can be used to connect with the second clamp 220 in the transformer 200.

[0050] Furthermore, in one embodiment, in combination Figure 3 and Figure 4 As shown, the number of the first telescopic rods 32 and the number of the second telescopic rods 34 are both multiple, the multiple first telescopic rods 32 are arranged at intervals along the periphery of the first support frame 31, and the multiple second telescopic rods 34 are arranged at intervals along the periphery of the second support frame 33. The first telescopic rods 32 and the second telescopic rods 34 are arranged one by one in the relative direction of the first support frame 31 and the second support frame 33. Each first connecting portion 321 is connected to the first support frame 31, and each second connecting portion 341 is connected to the second support frame 33. In this way, the volume of the transformer box structure 100 can be changed by sliding the first sliding portion 322 in the first telescopic rod 32 and the second sliding portion 342 in the second telescopic rod 34 opposite to the first telescopic rod 32. Among them, when reducing the volume of the transformer box structure 100, the first sliding part 322 and the second sliding part 342 can be slid as needed. For example, only part of the first sliding part 322 and the second sliding part 342 corresponding to the part of the first sliding part 322 can be slid to reduce the size of the flexible shell 1 in a certain direction; or, all the first sliding parts 322 and all the second sliding parts 342 can be slid at the same time to reduce the size of the flexible shell 1 in all directions.

[0051] Furthermore, in one embodiment, in combination Figure 2 and Figure 3 As shown, the number of the first telescopic rods 32 and the number of the second telescopic rods 34 are both four, and the four first telescopic rods 32 are evenly spaced along the periphery of the first support frame 31, and the four second telescopic rods 34 are evenly spaced along the periphery of the second support frame 33. In this way, when the bracket 3 is in the extended state, the flexible housing 1 can be bent and folded inward in multiple directions at the same time by sliding all the first sliding parts 322 and all the second sliding parts 342 at the same time, thereby reducing the overall volume of the transformer box structure 100 and achieving the purpose of convenient transportation.

[0052] Optionally, in the extended state, the bracket 3 can make the flexible shell 1 form a rectangular frame structure, wherein one end of the four first sliding parts 322 facing away from the first connecting part 321 is constrainedly matched with four corners of the flexible shell 1 close to the first clamp 210, and one end of the four second sliding parts 342 facing away from the second connecting part 341 is constrainedly matched with four corners of the flexible shell 1 close to the second clamp 220.

[0053] In another embodiment, in combination Figure 4 , Figure 5 and Figure 6 As shown, the number of the first telescopic rods 32 and the number of the second telescopic rods 34 are both eight, and the first support frame 31 and the second support frame 33 both have a first side A1 and a second side A2 relative to each other, wherein two first telescopic rods 32 are arranged on the first side A1 and are spaced apart, and the other two first telescopic rods 32 are arranged on the second side A2 and are spaced apart, and two of the remaining four first telescopic rods 32 are arranged on one side of the relative direction of the first side A1 and the second side A2 and are spaced apart, and the other two first telescopic rods 32 are arranged on the other side of the relative direction of the first side A1 and the second side A2 and are spaced apart. Among them, two second telescopic rods 34 are arranged on the first side A1 and are spaced apart, and the other two second telescopic rods 34 are arranged on the second side A2 and are spaced apart, and two of the remaining four second telescopic rods 34 are arranged on one side of the relative direction of the first side A1 and the second side A2 and are spaced apart, and the other two second telescopic rods 34 are arranged on the other side of the relative direction of the first side A1 and the second side A2 and are spaced apart. In this way, the flexible shell 1 can be contracted along the relative direction between the first side A1 and the second side A2, or can be contracted along a direction perpendicular to the relative direction between the first side A1 and the second side A2 and perpendicular to the relative direction between the first support frame 31 and the second support frame 33, or can be contracted in these two directions at the same time, so that the telescopic direction of the flexible shell 1 can be selected according to actual needs to achieve the characteristic of convenient transportation.

[0054] Specific, combined Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, when the relative direction between the first side A1 and the second side A2 is the S1 direction, the flexible shell 1 can be folded and contracted in the S1 direction by sliding the first sliding part 322 and the second sliding part 342 provided on the first side A1 and / or the second side A2; when the direction perpendicular to the relative direction between the first side A1 and the second side A2 and the direction perpendicular to the relative direction between the first support frame 31 and the second support frame 33 is the S2 direction, by sliding part or all of the first sliding parts and part or all of the second sliding parts arranged on the opposite sides of the S1 direction, the flexible shell 1 can be folded and contracted in the S2 direction; and when the flexible shell 1 needs to be folded in the S1 direction and the S2 direction at the same time, it is only necessary to slide part or all of the first sliding parts 322 and part or all of the second sliding parts 342 used in these two directions at the same time.

[0055] In another embodiment, in combination Figure 7 and Figure 8As shown, the bracket 3 includes a swing frame 35 and at least three bending rods 36. The swing frame 35 is used to be set on one side of the transformer 200, and the at least three bending rods 36 are used to be set on the other side of the transformer 200. The swing frame 35 includes a vertical rod 351, a sliding sleeve 352, at least three fulcrum rods 354 and at least three extension rods 353. One end of the vertical rod 351 is used to be connected to the transformer 200, and the other end is used to extend to a side away from the bending rod 36. The sliding sleeve 352 is slidably connected to the vertical rod 351. The at least three fulcrum rods 354 are spaced along the circumference of the vertical rod 351. They are arranged at intervals on the periphery of the vertical pole 351 and are used to connect with the first clamp 210. Each fulcrum rod 354 is provided with a fulcrum hole 354a. One end of each extension rod 353 is connected to the sliding sleeve 352, and the other end of the extension rod 353 passes through the fulcrum hole 354a one by one and extends to the side away from the vertical pole 351. At least three bending rods 36 are arranged at intervals along the circumference of the vertical pole 351, and each bending rod 36 includes a connecting rod 361 and a rotating rod 362 that are rotatably connected, and the end of each connecting rod 361 away from the rotating rod 362 is used for transformer connection. The sliding sleeve 352 can slide relative to the vertical rod 351 to make at least three extension rods 353 slide relative to the corresponding fulcrum rod 354 and swing relative to the corresponding fulcrum rod 354. Each rotating rod 362 can rotate relative to the corresponding connecting rod 361. In the extended state, one end of each extension rod 353 away from the sliding sleeve 352 extends to the side away from the bending rod 36, and the extension direction of each rotating rod 362 is consistent with the extension direction of the corresponding connecting rod 361. In the retracted state, one end of each extension rod 353 away from the sliding sleeve 352 extends to the side close to the bending rod 36, and one end of each rotating rod 353 away from the connecting rod 361 extends to the side close to the extension rod 353. In this way, the bracket 3 can be switched between the extended state and the retracted state by only moving the sliding sleeve 352 along the vertical pole 351 and bending the rotating rod 362, so that the size of the flexible shell 1 can be easily adjusted, and the volume of the transformer box structure 100 can be easily changed according to needs, which is conducive to the convenient transportation of transformer products.

[0056] Optionally, the extension direction of the vertical rod 351 may be the same as the relative direction of the swing frame 35 and the bending rod 36 .

[0057] Optionally, the vertical rod 351 can be used to connect with the first clamp 210 in the transformer 200. At least three fulcrum rods 354 can be used to connect with the transformer 200. Specifically, each fulcrum rod 354 is used to connect with the first clamp 210 in the transformer 200. One end of each connecting rod 361 away from the rotating rod 362 can be used to connect with the second clamp 220 in the transformer 200.

[0058] In one embodiment, Figure 1 , Figure 2 , Figure 3 As shown, the transformer box structure 100 includes a lifting rod 2, one end of which is used to connect with the transformer 200, and the other end passes through the flexible shell 1 to form a lifting end, and the lifting end is provided with a lifting hole. In this way, when the hook of the crane is hooked to the lifting hole, the crane can reliably lift the transformer box structure 100 with the transformer 200 installed, so that the transformer box structure 100 can be easily loaded and unloaded on the transport vehicle during transportation.

[0059] Optionally, the number of the lifting rods 2 may be three, and the three lifting rods 2 are used to be arranged at intervals along the periphery of the transformer 200. One end of the lifting rod 2 is used to be connected to the first clamp 210 of the transformer 200.

[0060] In one embodiment, in combination Figure 3 , Figure 4 As shown, the flexible housing 1 is provided with a first wire hole 1c and a second wire hole connected to the installation cavity 1b, the first wire hole 1c is used for the high-voltage wire to pass through, and the second wire hole is used for the low-voltage wire to pass through. In this way, the high-voltage wire can pass through the first wire hole 1c into the installation cavity 1b and connect to the high-voltage terminal in the transformer 200, and the low-voltage wire can pass through the second wire hole into the installation cavity 1b and connect to the low-voltage terminal in the transformer 200, so that the transformer 200 can effectively realize its functional role.

[0061] The positions of the optional first wire hole 1c and the second wire hole can be set as needed. For example, the first wire hole 1c can be opened on the part of the flexible shell 1 close to the first clamp 210, and the second wire hole can be set on the part of the flexible shell 1 close to the second clamp 220.

[0062] In one embodiment, the bracket 3 is provided with a first connecting piece, and the flexible housing 1 is provided with a second connecting piece, and the first connecting piece and the second connecting piece are detachably connected. In this way, when the state of the bracket 3 is switched, the flexible housing 1 can follow the movement of the bracket 3 in real time to achieve a rapid change in the volume of the transformer box structure 100. At the same time, when the bracket 3 is in the extended state, the flexible housing 1 will not move relative to the bracket 3, which is conducive to ensuring the electrical distance between the flexible housing 1 and the transformer 200 in the extended state.

[0063] Optionally, one of the first connecting member and the second connecting member may be a hook, and the other may be a snap ring.

[0064] In other embodiments, the bracket 3 and the flexible shell 1 may not be connected so that the portion of the bracket 3 used to support the flexible shell 1 can be separated from the flexible shell 1. In this way, when the bracket 3 is contracted, the volume of the transformer 200 can be changed by manually folding or bending the flexible shell 1.

[0065] In one embodiment, Figure 1 and Figure 2 As shown, the flexible shell 1 is provided with an installation opening 1a, which is connected to the installation cavity 1b, and the transformer box structure 100 also includes a closure member, which is used to open or close the installation opening 1a. In this way, when the installation opening 1a is in an open state, the transformer 200 can be installed in the installation cavity 1b through the installation opening 1a, and the wiring operation of the transformer 200 can be completed through the installation opening 1a. When the assembly between the transformer 200 and the flexible shell 1 is completed, the installation opening 1a can be closed by the closure member, so that the flexible shell 1 can wrap the transformer 200 located in the installation cavity 1b, so that the transformer box structure 100 can be packaged and shipped together with the transformer 200, and during the transportation process, the volume of the transformer box structure 100 can be changed according to actual needs to achieve convenient transportation.

[0066] Optionally, the opening position of the installation port 1a can be set as needed. When the transformer 200 product is installed in a distribution room, the position of the installation port 1a should avoid the position of equipment and walls near the transformer product, so that the installation port 1a can be opened when the transformer 200 is inspected to achieve convenient maintenance.
