[0044] The present utility model proposes a transformer with air cable box free of support and fixed

[0045] In the embodiments of the present utility model, as Figures 1 to 6 、 Figure 9 shown, the transformer with air cable box free of support and fixed includes a transformer body 1, a low-voltage junction box 2, an air cable box body 3, and a first fixing component 4;

[0046] The low-voltage junction box 2 is arranged on one side of the transformer body 1, and a low-voltage bushing 5 is arranged in the low-voltage junction box 2;

[0047] The air cable box body 3 includes a housing 31, a connecting row 32 and a second fixing component 33 arranged in the housing 31. A through port 311 is provided at one end of the housing 31 close to the low-voltage junction box 2. The low-voltage bushing 5 passes through the through port 311 and is connected to the connecting row 32. The housing 31 is fixedly connected to the low-voltage junction box 2; The second fixing component 33 includes clamping plates 331 arranged at intervals along the height direction of the connecting row 32, and the connecting row 32 is clamped and fixed between the two clamping plates 331;

[0048] The first fixing component 4 includes a fixing plate 41 and a pull rod 42. Fixing plates 41 are respectively arranged on the side wall of the transformer body 1 and the top surface of the housing 31. One end of the pull rod 42 is fixedly connected to the fixing plate 41 arranged on the side wall of the transformer body 1, and the other end of the pull rod 42 is fixedly connected to the fixing plate 41 arranged on the housing 31. The pull rod 42 is obliquely arranged.

[0049] The technical solution of the present utility model fixedly connects the transformer body 1 and the air cable box body 3 through the first fixing component 4. A triangular fixing structure is formed among the pull rod 42, the transformer body 1 and the air cable box body 3, which can avoid the shaking of the air cable box during transportation and improve the connection stability of the overall structure; The clamping plates 331 in the second fixing component 33 are arranged at intervals along the height direction of the connecting row 32 and are used to clamp and fix the connecting row 32, so as to realize the fixed connection between the connecting row 32 and the air cable box body 3 and further improve the stability of the overall structure. In the present utility model, the air cable box body 3 is connected through two connection points. The first connection point is the connection between the low-voltage junction box 2 and the air cable box body 3, and the second connection point is the connection between the air cable box body 3 and the transformer body 1 through the first fixing component 4, thereby realizing that the air cable box is free of support and fixedly connected to the transformer. The overall structure has high stability during transportation and avoids damage to the product. The transformer and the air cable box do not need to be packaged and transported separately. Therefore, there is no need to consider the support and fixation of the air cable box after arriving at the site, and at the same time, the situation of overly complex packaging and transportation is also avoided, reducing manpower and material resources, and thus the transportation cost can be reduced. It solves the problems that the transformer and the air cable box are currently packaged and transported separately, so it is necessary to consider the support and fixation of the air cable box during on-site installation and the high transportation cost.

[0050] Specifically, the connecting row 32 is a copper row.

[0051] Preferably, the fixing plates 41 are respectively arranged on the side wall of the transformer body 1 and the top surface of the air cable box body 3 by welding.

[0052] Such as Figure 3 AndFigure 4 As shown, in an embodiment of the present application, the tie rod 42 includes a rod body 421 and a connecting member 422. A first notch 422a is formed at the end of the connecting member 422, and both ends of the rod body 421 in the length direction are respectively inserted into the first notch 422a of the connecting member 422;

[0053] The first fixing assembly 4 further includes a fastener. The fixing plate 41 and the connecting member 422 are respectively provided with first mounting holes 43, and the first mounting holes 43 of the fixing plate 41 and the first mounting holes 43 of the connecting member 422 are arranged in one-to-one correspondence;

[0054] The fastener passes through the first mounting hole 43 of the fixing plate 41 and the first mounting hole 43 of the connecting member 422 to fixedly connect the fixing plate 41 and the connecting member 422.

[0055] The tie rod 42 plays an important role in connecting the transformer body 1 and the air cable box body 3. In order to further improve the stability of the overall structure, both ends of the rod body 421 of the tie rod 42 in the length direction are respectively inserted into the first notch 422a of the connecting member 422. By means of the connecting member 422, the contact area between the tie rod 42 and the fixing plate 41 is increased, and then the fixing plate 41 and the connecting member 422 are fixed by the fastener, further making the connection between the air cable box body 3 and the transformer body 1 more stable, effectively reducing the situation of shaking or offset of the air cable box during transportation. In addition, the tie rod 42 with this structure is applicable to transformers and air cable boxes of different sizes, improving the versatility of the tie rod 42.

[0056] Specifically, the fastener is a bolt.

[0057] Preferably, the diameter of the rod body 421 is 16 mm. When the positions of the first mounting holes 43 of the fixing plate 41 and the first mounting holes 43 of the connecting member 422 correspond, the two are fixed by bolts. The threaded connection method can prevent the connection between the two from loosening, resulting in poor connection stability between the transformer and the air cable box. The first mounting holes 43 are respectively formed in the fixing plate 41 and the connecting member 422, which also facilitates the disassembly and assembly of the air cable box, providing convenience for subsequent maintenance, component replacement, etc.

[0058] As [[ID=2)] Figure 1 and Figure 2 shown, in an embodiment of the present application, the fixing plate 41 is arranged near the center position of the housing 31.

[0059] The fixing plate 41 is arranged near the center position of the housing 31. Thus, when the tie rod 42 is connected to the fixing plate 41, it is ensured that the housing 31 receives the same or similar tensile force, thereby avoiding the situation that the air cable box body 3 is deformed due to uneven stress.

[0060] As Figure 1 andFigure 2 As shown, in an embodiment of the present application, two first fixing components 4 are provided, and the two first fixing components 4 are symmetrically arranged at the central position of the housing 31.

[0061] The symmetrical arrangement of the two first fixing components 4 can provide a more uniform fixing force, ensuring that the housing 31 and the internal components of the air cable box can remain stable when subjected to external forces, and improving the connection stability of the overall structure.

[0062] As Figures 5 to 8 shown, in an embodiment of the present application, second notches 331a are respectively formed at opposite ends of the two clamping plates 331, and the number of the second notches 331a is corresponding to the number of the connection rows 32, and the connection rows 32 are clamped and fixed between the second notches 331a of the two clamping plates 331.

[0063] The formation of the second notches 331a corresponding to the number of the connection rows 32 on the clamping plates 331 provides a stable support and clamping environment for the connection rows 32, realizing clamping and fixing the connection rows 32 between the second notches 331a of the two clamping plates 331, and preventing the connection rows 32 from moving or loosening during transportation.

[0064] As Figures 6 to 8 shown, in an embodiment of the present application, the second fixing component 33 further includes a support frame 332, a screw 333 and a nut 334. The support frame 332 is fixedly arranged on the inner side wall of the housing 31, the screw 333 is fixedly arranged on the support frame 332, and the clamping plate 331 is provided with a second mounting hole 331b therethrough, and the screw 333 passes through the second mounting hole 331b;

[0065] The nut 334 is tightened on the screw 333 and abuts against the clamping plate 331 to fix the clamping plate 331 to the screw 333.

[0066] By providing the support frame 332 to support one of the clamping plates 331, the screw 333 passes through the second mounting hole 331b of the clamping plate 331, and then the screw 333 is tightened by the nut 334 to fix the clamping plate 331, the support frame 332 and the screw 333, thereby making the connection between the connection row 32 and the cable box body 3 more stable.

[0067] As Figure 8 shown, in an embodiment of the present application, the support frame 332 is in an L shape.

[0068] The setting of the support frame 332 enables the clamping plate 331 to be fixed more stably within the air cable box body 3. The L-shaped support frame 332 is suitable for the connection between the end of the clamping plate 331 and the edge position of the inner wall of the air cable box body 3, and can more effectively withstand the external force effects from two directions. The support frame 332 provides stable and reliable support for the clamping plate 331, and further provides stable support for the connection row 32, enabling the connection row 32 to be firmly fixed within the air cable box body 3 and preventing the connection row 32 from shaking during transportation.

[0069] As Figures 6 to 8 shown, in an embodiment of the present application, at least two second fixing components 33 are provided, and the second fixing components 33 are arranged at intervals along the length direction of the connection row 32.

[0070] Arranging at least two second fixing components 33 at intervals along the length direction of the connection row 32 can further improve the connection stability and reliability between the connection row 32 and the air cable box body 3, and is applicable to connection rows 32 of different lengths.

[0071] Preferably, the number of the second fixing components 33 is two. One of the second fixing components 33 is arranged close to the connection position of the connection row 32 and the low-voltage bushing 5, and the other second fixing component 33 is arranged close to one end of the connection row 32 away from the low-voltage bushing 5.

[0072] As Figure 1 , Figure 7 , Figures 9 to 11 shown, in an embodiment of the present application, the air cable box body 3 further includes a first cover plate 34, a second cover plate 35, a heat dissipation plate 36, and a bottom plate 37;

[0073] A first opening 312 is formed through the top surface of the housing 31, and the first cover plate 34 is arranged at the first opening 312;

[0074] A second opening 313 is formed through one end of the housing 31 away from the low-voltage junction box 2, and the second cover plate 35 is arranged at the second opening 313;

[0075] Third openings 314 and fourth openings 315 are respectively formed through the two side surfaces of the housing 31, and the heat dissipation plate 36 is arranged at the third openings 314 and the fourth openings 315;

[0076] A fifth opening 316 is formed through the bottom surface of the housing 31, and the bottom plate 37 is arranged at the fifth opening 316; a sixth opening 371 is formed through the bottom plate 37, and the sixth opening 371 is arranged in one-to-one correspondence with the connection row 32.

[0077] The first cover plate 34 and the second cover plate 35 are provided to facilitate the opening of the air cable box for connecting cables and subsequent maintenance. To prevent heat generated by the cables in the cable box during long-term power-on and load operation from accumulating inside the cable box, a heat dissipation plate 36 is provided, which can improve the overall heat dissipation performance of the cable box and extend its service life. A bottom plate 37 is provided. When maintenance and repair of the air cable box are required, maintenance can also be carried out by removing the bottom plate 37, without the need to replace the entire air cable box, improving maintenance efficiency and reducing maintenance costs. The sixth opening 371 corresponds to the connection row 32 one by one. The sixth opening 371 is provided to enable the connection row 32 to lead to the cable well after being connected to the low-voltage outgoing cable.

[0078] Preferably, the first cover plate 34, the second cover plate 35, the heat dissipation plate 36, the bottom plate 37, and the clamping plate 331 are all epoxy resin plates. Epoxy resin plates have excellent insulation performance, ensuring that the cable box maintains a stable insulation state in a complex working environment; they also have good sealing performance, capable of effectively blocking air, moisture, and other chemical substances from entering the cable box, improving the safety performance of the cable box.

[0079] As Figure 1 、 Figure 6 、 Figure 9 and Figure 11 shown, in an embodiment of the present application, handles 38 are respectively provided on the outer surfaces of the first cover plate 34 and the second cover plate 35;

[0080] The third opening 314 and the fourth opening 315 are arranged close to the connection row 32, and the third opening 314 and the fourth opening 315 are symmetrically arranged. The heat dissipation plate 36 is in a grid shape.

[0081] The provision of the handle 38 facilitates the operator to open and close the handhole cover plate. In the case of frequent operation, the provision of the handle 38 can significantly improve the convenience and efficiency of operation. Preferably, the first cover plate 34 is provided with 4 handles 38, and the 4 handles 38 are symmetrically arranged in pairs. Two of the symmetric handles 38 are respectively arranged on one side of the two fixing plates 41 close to the edge of the first cover plate 34; the second cover plate 35 is provided with 2 handles 38. At this time, the 2 handles 38 on the second cover plate 35 are also symmetrically arranged.

[0082] Since the connection row 32 is connected to the cable line, a large amount of heat will be generated by the connection row 32, and timely and effective heat dissipation is required. At this time, the third opening 314 and the fourth opening 315 are arranged close to the connection row 32, which is convenient for arranging the heat dissipation plate 36, and thus can effectively improve the heat dissipation effect of the connection row 32. The third opening 314 and the fourth opening 315 are symmetrically arranged. At this time, the two heat dissipation plates 36 are symmetrically arranged. The symmetric arrangement of the heat dissipation plates 36 can reduce the interference of air flow, can make more effective use of the air flow for heat dissipation, and improve the heat dissipation effect inside the air cable box.

[0083] The grid-shaped heat sink 36 not only dissipates heat but also has certain waterproof and dustproof functions, preventing the outside from accidentally touching the connection bar 32, thereby protecting the interior of the cable box from pollution and damage.

[0084] Preferably, the first cover plate 34 and the second cover plate 35 are respectively a hand hole cover plate. The hand hole cover plate can withstand a certain amount of external pressure and impact, thereby protecting the interior of the cable box from the external environment. It can also be easily opened when needed, facilitating operations such as internal inspection, maintenance, and cable replacement of the cable box, reducing the difficulty and time of maintenance work and improving maintenance efficiency.

[0085] A radiator is provided on each side of the air cable box body 3. The transformer generates a large amount of heat during operation. The radiator can quickly dissipate the heat generated inside the transformer to the external environment to ensure that the transformer temperature does not become too high. Preferably, the radiator is a plate-type radiator.

[0086] Preferably, a rain shielding eave is extended along the four edges of the top surface of the shell 31. The rain shielding eave can prevent rain from directly wetting the air cable box, play a role in protecting the air cable box, and ensure the normal operation of the electrical system.

[0087] To further illustrate, a cover plate is provided on the side of the low-voltage junction box 2 connected to the low-voltage bushing 5, on which a threaded sleeve is provided, and an opening is provided at a corresponding position on the back of the air cable box body 3, and a bolt is used to tighten the cover plate of the low-voltage junction box 2 from the direction of the air cable box body 3;

[0088] The specific installation process is as follows:

[0089] First, use bolts to connect the air cable box body 3 to the low-voltage junction box 2, fix the clamping plate 331 on the support frame 332, then connect the connecting row 32 to the low-voltage bushing 5, place the connecting row 32 on the second slot 331a of the clamping plate 331, and then install another clamping plate 331 on the connecting row 32, tighten the nut 334 to the screw 333, fix the two clamping plates 331 to the connecting row 32, then install the first cover plate 34, and finally install the first fixing component 4 to connect the air cable box body 3 to the transformer body 1.
