Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and specifically provides an anti-collision Chinese-style box transformer. Background Art

[0002] Box transformer refers to box-type substation or prefabricated substation, which is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformer and low-voltage distribution device. In order to reduce the construction volume of box transformer outdoors and improve the efficiency of outdoor construction, the existing box transformer is usually assembled in the factory, and then the assembled box transformer is transported to the construction site, and then the assembled box transformer is transported to the construction site.

[0003] However, during transportation, there is a risk of mutual squeezing between box-type transformers. Compared with the box-type transformers whose other parts are protected by the box body, the heat sink of the box-type transformer needs to be exposed to the air to achieve heat dissipation, so mutual squeezing between box-type transformers can easily cause damage to the heat sink. Therefore, the problem of heat sink damage caused by mutual squeezing during transportation of box-type transformers needs to be solved urgently. Utility Model Content

[0004] The utility model provides an anti-collision Chinese-style box transformer, which is used to solve the problem that the heat sink may be damaged due to mutual squeezing during the transportation of the box transformer.

[0005] The technical solution of the utility model is as follows:

[0006] A collision-proof Chinese-style box transformer comprises a radiator and a protective structure. The radiator is provided with cooling fins. The protective structure is arranged on the side of the cooling fins and is connected to the radiator.

[0007] In this solution, a protective structure is provided on the side of the heat sink, and the protective structure is connected to the radiator. When the box transformer is squeezed during transportation, when the squeezing point between the box transformers is located at the position of the heat sink, the squeezing force will act on the protective structure. The protective structure can protect the heat sink and prevent the heat sink from direct contact with other structures, thereby preventing the heat sink from being damaged or deformed.

[0008] Preferably, the protection structure includes a protection part, and the protection part includes a protection plate or a protection frame.

[0009] In this solution, the protective plate and the protective frame are structures that are easy to manufacture and form, which makes it easy to control processing costs.

[0010] In order to solve the problem that the protective plate blocks the air flow and affects the heat dissipation efficiency of the heat sink, the protective plate is provided with ventilation holes.

[0011] In this solution, the protective plate is provided with ventilation holes so that air can pass through the protective plate through the ventilation holes, thereby improving heat dissipation efficiency.

[0012] Preferably, the protective part is C-shaped and surrounds the heat sink from three directions.

[0013] To solve the problem that the protective part is not stably installed and is easily detached when collided, the protective structure further includes support columns fixed to the radiator. The protective part is connected to the support columns and the radiator respectively through fasteners, and the protective part is used to protect the heat sink from the side.

[0014] In this solution, support columns are provided to connect with the protective part. The support columns can play a role in supporting the protective part. The support columns increase the connection points of the protective part, which can improve the stability of the protective part.

[0015] Preferably, connecting pieces are respectively arranged at the top and bottom of the support columns, and the top and bottom of the support columns are respectively connected to the radiator through the connecting pieces.

[0016] In this solution, the support columns are connected to the radiator through the connecting pieces. The connecting pieces can increase the distance between the support columns and the heat sink, thereby increasing the distance between the protective part and the heat sink. When the distance between the protective part and the heat sink increases, even if the protective part undergoes a certain deformation during collision and extrusion, it can be avoided that the deformed protective part contacts the heat sink, ensuring that the heat sink will not be damaged.

[0017] Preferably, the connecting piece includes a connecting plate or a connecting beam.

[0018] In this solution, using a connecting plate as the connecting piece can reduce the weight, while using a connecting beam can increase the connection strength and ensure the stability of the support columns.

[0019] Preferably, the protection plate includes at least two unit plates, and the unit plates are connected to each other, or the unit plates are connected to the support columns, or the unit plates are connected to the radiator.

[0020] In this solution, the protection plate can be composed of multiple unit plates, which is more convenient for processing and forming the protection plate. When installing the unit plates, the unit plates on both sides can be directly connected to the radiator to fix both sides of the assembled protection plate. The unit plates in the middle can be connected to the unit plates or the support columns to fix the unit plates.

[0021] Preferably, side bars are arranged on the sides of the unit plates, and connection holes are arranged on the side bars.

[0022] In this solution, fasteners such as screws can be used to pass through the connection holes and connect to the radiator and the support columns, or bolts can be used to pass through the connection holes, and the bolts are used in cooperation with nuts to fixedly connect the two unit plates.

[0023] Preferably, the connection hole is a strip-shaped hole.

[0024] In this solution, the strip-shaped holes can solve the problem of assembly error.

[0025] Advantages of the present utility model:

[0026] The present utility model provides a protection structure on the side of the heat sink, which forms an occlusion of the heat sink from the side through the protection structure, thereby avoiding damage to the heat sink caused by extrusion with other structures during transportation.

[0037] With reference to the drawings, through the specific embodiments of the present utility model, the technical solution of the present utility model will be clearly and completely described.

[0038] Embodiment 1:

[0039] As Figure 1 shown, Embodiment 1 of the present invention provides an anti-collision Huashi box-type substation, which includes a box body 5, a radiator 1 and a protection structure. The radiator 1 is provided with heat dissipation fins 2, and the heat dissipation fins 2 are exposed to the outside air. The heat dissipation fins 2 are used for heat exchange with the air to achieve the effect of heat dissipation. The protection structure is connected to the radiator 1, and the protection structure is arranged on the side of the heat dissipation fins 2 to protect the heat dissipation fins 2 from the side, so as to prevent the Huashi box-type substation from being deformed and damaged due to collision and extrusion with other structures during transportation. Among them, the radiator 1 is installed on one side of the box body 5, and the box body 5 is used for installing equipment such as transformers.

[0040] As Figure 3 shown, three sides of the heat dissipation fins 2 are exposed to the air, and the other side is connected to the body of the radiator 1. The three sides are all provided with the protection structure to ensure that the heat dissipation fins 2 can be protected in three directions.

[0041] As Figure 2 shown, the protection structure includes a protection part 4 and a support column 3. The support column 3 is connected to the radiator 1, and the protection part 4 is respectively connected to the support column 3 and the radiator 1. The setting of the support column 3 can increase the connection points of the protection part 4 and improve the stability of the protection part 4.

[0042] The shape of the protection part 4 in the top view is C-shaped. The C-shaped protection part 4 protects the heat dissipation fins 2 from three directions respectively.

[0043] The protection part 4 can be a protection plate or a protection frame.

[0044] If the protection part 4 is a protection plate, the protection plate can be bent and formed from a whole piece of plate, or the protection plate can also be formed by splicing multiple unit plates 41. The size of the box-type substation is large, and the area of the protection plate is large, which is not convenient for installation. Therefore, multiple unit plates 41 can be spliced to form the protection plate to reduce the installation difficulty. The number of unit plates 41 can be two, three, four or more.

[0045] When the unit plates 41 are installed, the unit plates 41 on both sides are respectively connected to the radiator 1. The unit plates 41 in the middle can be connected to the adjacent unit plates 41, and the unit plates 41 in the middle can also be connected to the support column 3. Taking the unit plates 41 on both sides as an example, one side of the unit plates 41 on both sides will be connected to the radiator 1 through fasteners, and the other side of the unit plate 41 also needs to be fixed. At this time, the other side of the unit plate 41 can be connected to another unit plate 41 or to the support column 3. As Figure 4As shown, when the unit boards 41 are connected to each other, a strip board 44 can also be used to connect two unit boards 41 respectively, and the two unit boards 41 are connected into a whole through the strip board 44. Strip holes can also be formed in the strip board 44. Among them, the length direction of the strip holes on the strip board 44 is the horizontal direction, while the length direction of the connection holes 43 is the vertical direction. Therefore, the strip holes on the strip board 44 can solve the assembly error problem of the protection part 4 in the horizontal direction, and the connection holes 43 on the unit board 41 can solve the assembly error problem of the protection part 4 in the vertical direction. The assembly errors are eliminated through the strip holes.

[0046] As Figure 5 shown, a side strip 45 is provided on the side of the unit board 41, and the side strip 45 is a sheet-like structure. Connection holes 43 are provided on the side strip 45. By using fasteners such as bolts to cooperate with the connection holes 43, the fixation of the unit board 41 can be realized. For example, after the bolt passes through the connection hole 43 and is fixedly connected to the screw hole formed on the radiator 1, the unit board 41 can be fixed to the radiator 1. Another example is that the side strips 45 of two unit boards 41 overlap, so that the connection holes 43 on the two unit boards 41 are coaxial. By using a bolt to pass through the two connection holes 43 and then assembling a nut on the bolt, the two unit boards 41 can be fixed. Similarly, the unit board 41 and the support column 3 can also be fixed by bolts, and through holes or screw holes can be formed on the support column 3.

[0047] The connection hole 43 is a strip hole. The provision of the strip hole can solve the problem that the connection holes 43 cannot be coaxial due to assembly errors during the installation of the unit board 41.

[0048] It should be noted that connection holes 43 can also be formed on the main body of the unit board 41 to facilitate the connection with the support column 3. That is to say, the number of support columns 3 can be increased, and the support column 3 is connected to the middle part of the unit board 41 to further increase the stability of the unit board 41, thereby increasing the stability of the entire protection board.

[0049] The unit board 41 can be a flat board, and the unit board 41 can also be a bent board. For example, to form a C-shaped protection board, the two sides of the protection board are inclined or perpendicular to the middle part, and there are two corner positions on the protection board. Therefore, at the corner positions of the protection board, a bent board can be provided as a transition, so that the two sides of the bent board are respectively connected to other unit boards 41, and two bent boards can be provided on one protection board to form a C-shaped shape. If all the unit boards 41 are flat boards, the side strip 45 of a unit board 41 at the corner position is perpendicular or inclined to the main body of the unit board 41. After the two side strips 45 are fixedly connected, the two unit boards 41 are also in an inclined or perpendicular state.

[0050] The protective plate is provided with ventilation holes, which facilitate air circulation and are used to solve the problem that the protective plate blocks air flow and reduces the heat dissipation efficiency of the heat sink 2. The height of the top of the protective plate from the ground is 1-1.5m, so that the protective plate can protect the heat sink 2 in the horizontal direction while avoiding too much blockage of air flow by the protective plate.

[0051] Multiple ventilation holes are provided on the protective plate to improve the ventilation effect of the protective plate.

[0052] When the protection part 4 is a protection frame, the protection frame is a frame structure formed by welding profiles. There is a hollow in the middle of the frame structure, so the influence of the frame structure on air flow is small and it will not affect the heat dissipation of the heat sink 2. The protection frame can include multiple rectangular frames, and the multiple rectangular frames are connected by welding or fasteners to form a C-shaped frame.

[0053] However, the protection frame needs to be formed by welding profiles, and the processing cost is higher than that of the protective plate. Therefore, it is preferred to use the protective plate as the protection part 4.

[0054] As Figure 6 shown, connectors are respectively arranged at the top and bottom of the support column 3, and the support column 3 is connected to the radiator 1 through the connectors. The connectors are arranged horizontally, and the distance between the support column 3 and the heat sink 2 can be increased through the connectors, so as to increase the distance between the protection part 4 and the heat sink 2.

[0055] The connector can be a connecting plate 6 or a connecting beam 7.

[0056] The connecting plate 6 is processed from a plate. One end of the connecting plate 6 is welded to the support column 3, and a connecting hole 43 is arranged at the other end. Fasteners such as screws can be used to pass through the connecting hole 43, and then the connecting plate 6 is fixed to the radiator 1.

[0057] The connecting beam 7 is processed from a profile. One end of the connecting beam 7 can be welded or connected by fasteners to the support column 3, and a connecting hole 43 is arranged at the other end of the connecting beam 7.

[0058] The connecting beam 7 has higher strength than the connecting plate 6 and is less likely to deform, and can play a better supporting role. The advantage of the connecting plate 6 is that it is light in weight and small in volume.

[0059] A connecting beam 7 is arranged at the bottom of the support column 3, and a connecting plate 6 is arranged at the top of the support column 3.

[0060] For the convenience of maintenance, disassembly and assembly of the support column 3, the connecting beam 7 at the bottom and the connecting plate 6 at the top of the support column 3 are respectively connected to the radiator 1 through fasteners such as bolts. As Figure 7As shown in the figure, a lug plate 8 is welded on the radiator 1, and through holes are opened on the lug plate 8. An angle steel 9 with through holes on both sides is used to connect the connecting plate 6 and the lug plate 8 into a whole respectively, so as to realize the fixation of the connecting plate 6 and the lug plate 8, that is, to realize the fixation of the support column 3 and the radiator 1. The connecting beam 7 and the radiator 1 can also be fixed by the same mechanism.

[0061] The support column 3 can be made of profiles such as rectangular tubes.
