It adopts a factory prefabrication design and is enclosed in a moisture-proof, rust-proof, and dust-proof fully enclosed steel structure box. Its structure typically includes a high-voltage section, a transformer section, and a low-voltage section.

[0003] In the past, the top lifting rings of prefabricated substations did not have a reinforced structure during hoisting, which made them less safe to install. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a prefabricated substation with a reinforced structure, which improves safety during hoisting.

[0005] The technical solution adopted by this utility model to solve its technical problem is a box-type substation, including a main box, a door, a base plate, a low-voltage box, a transformer and a high-voltage box. The main box has a door on the front side. The low-voltage box and the high-voltage box are respectively installed at the bottom of the main box near the two ends of the base plate through mounting seats. The transformer is installed at the bottom of the main box near the low-voltage box and the high-voltage box. A first heat dissipation groove is opened on the door. Cable routing grooves are opened on the back of the main box near both ends.

[0006] Triangular plates are fixed to the top corners on both sides of the main housing with screws. Connecting ears are extended from both ends of the triangular plates. Horizontal plates are provided at the top of the main housing near both sides. U-shaped connecting frames are welded to the top two ends and bottom two sides of the horizontal plates. The U-shaped connecting frames are connected to the connecting ears by pins and cotter pins. Connecting plates are also bolted to the top two ends of the main housing. A lifting ring is provided on the top of the connecting plate. A groove is opened on one side of the fixing post of the lifting ring. Connecting pieces are connected to the horizontal plates near both ends. The connecting pieces are fastened to the grooves with screws.

[0007] By adopting the above technical solution, a horizontal plate spans the top of the main box, and triangular plates are connected to the two sides of the main box near the top corner. The connecting ears at both ends of the triangular plates are then connected to the U-shaped connecting frames welded to the top and bottom of the horizontal plate by pins. The fixing column part of the lifting ring is connected to the connecting piece on one side of the horizontal plate, and the connecting plate at the bottom of the lifting ring is connected to the top of the main box, which can effectively strengthen the lifting ring.

[0008] Specifically, the outer side of the horizontal plate is provided with transverse reinforcing ribs near the center and both sides, and vertical reinforcing ribs are connected between the outer side of the horizontal plate near the transverse reinforcing ribs.

[0009] Specifically, a second heat dissipation groove is provided through both ends of the main housing near the top, and a fan is provided on the inner wall of the main housing at the position corresponding to the second heat dissipation groove.

[0012] Specifically, the signal output terminal of the temperature sensor is connected to the signal input terminal of the controller via a signal connection line, and the signal output terminal of the controller is connected to the control circuit of the alarm via a signal connection line.

[0013] By adopting the above technical solution, the temperature inside the main chamber can be easily monitored by a temperature sensor. When the temperature exceeds the set value, the controller controls the control circuit of the alarm to be powered on, thereby causing the alarm to sound.

[0014] Specifically, a bottom plate is provided at the lower end of the main housing, and extension columns are connected to the bottom of the main housing near the corners. Bottom columns are provided at the top of the bottom plate and at the corresponding positions of the extension columns. The extension columns and bottom columns are connected to each other by a columnar spring with a diameter greater than 30mm.

[0015] By adopting the above technical solution, the base column, columnar spring and extension column can play a certain buffering role when the main box is hoisted and placed on the installation surface, so as to prevent damage to the internal structure of the main box.

[0016] Specifically, a reserved groove is provided through the bottom of the base plate, and a support frame is provided between the inner walls of the reserved groove. A strip groove is provided near the corner of the bottom of the base plate.

[0030] To ensure the lifting rings of this substation have a reinforced structure and improve safety during hoisting, such as... Figure 1-7 As shown, the present invention discloses a prefabricated substation comprising a main enclosure 1, a door 7, a base plate 3, a low-voltage enclosure 31, a transformer 26, and a high-voltage enclosure 25. The main enclosure 1 has a door 7 on its front side.

A first heat dissipation groove 8 is provided on the door 7. Cable routing grooves 24 are provided on the back of the main enclosure 1 near both ends.

[0031] Triangular plates 18 are fixed to the top corners of both sides of the main housing 1 with screws. Connecting ears 19 are extended from both ends of the triangular plates 18. Horizontal plates 14 are provided at the top of the main housing 1 near both sides. U-shaped connecting brackets 17 are welded to the top two ends and bottom two sides of the horizontal plates 14. The U-shaped connecting brackets 17 and connecting ears 19 are connected by pins 20 and cotter pins. Connecting plates 12 are also bolted to the top two ends of the main housing 1. Lifting rings 13 are provided at the top of the connecting plates 12. A groove is opened on one side of the fixing post of the lifting rings 13. Connecting pieces 32 are connected to one side of the horizontal plates 14 near both ends. The connecting pieces 32 are fastened to the grooves with screws.

[0032] In use, a horizontal plate 14 spans the top of the main housing 1, and triangular plates 18 are connected to the corners near the top on both sides of the main housing 1. The connecting ears 19 at both ends of the triangular plates 18 are then connected to the U-shaped connecting frames 17 welded to the top and bottom of the horizontal plate 14 via pins 20. The fixing post part of the lifting ring 13 is connected to the connecting piece 32 on one side of the horizontal plate 14, and the connecting plate 12 at the bottom of the lifting ring 13 is connected to the top of the main housing 1, which can effectively strengthen the lifting ring 13.

[0033] For example, such as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the present invention also includes transverse reinforcing ribs 15 provided on the outer side of the horizontal plate 14 near the center and on both sides, and vertical reinforcing ribs 16 connected on the outer side of the horizontal plate 14 near the transverse reinforcing ribs 15.

[0034] When in use, the overall strength of the horizontal plate 14 can be effectively improved by using the horizontal reinforcing ribs 15 and the vertical reinforcing ribs 16.

[0035] For example, such as Figure 5 and Figure 6 As shown, the present invention also includes a second heat dissipation groove 21 that is provided through both ends of the main housing 1 near the top, and a fan 28 is provided on the inner wall of the main housing 1 at a position corresponding to the second heat dissipation groove 21.

[0036] During use, the fan 28 and the second heat dissipation slot 21 can effectively improve the heat dissipation effect inside the main housing 1.

[0037] For example, such as Figure 1-3 As shown, the present invention also includes a pad 11 provided between the connecting plate 12 and the main housing 1, the pad 11 being made of rubber material.

[0038] During use, the pad 11 can protect the connection surface between the connecting plate 12 and the main housing 1.

[0039] For example, such as Figure 1-3 As shown, this utility model also includes a controller 27 installed on the inner wall of the main housing 1 near the top via a mounting base, a temperature sensor 30 installed on one end of the inner wall of the main housing 1 near the lower side of the fan 28 via a mounting bracket 29, a mounting plate 22 connected to one end of the main housing 1, and an alarm 23 installed on the top of the mounting plate 22 via screws.

[0040] In use, the temperature sensor 30 can be installed inside the main enclosure 1 via the mounting bracket 29, and the alarm 23 can be installed outside the main enclosure 1 via the mounting plate 22.

[0041] For example, such as Figure 1-5 As shown, the present invention also includes a signal output terminal of the temperature sensor 30 connected to the signal input terminal of the controller 27 via a signal connection line, and a signal output terminal of the controller 27 connected to the control circuit of the alarm 23 via a signal connection line.

[0042] During use, the temperature sensor 30 can be used to monitor the temperature inside the main housing 1. When the temperature exceeds the set value, the controller 27 controls the control circuit of the alarm 23 to be powered on, so that the alarm 23 will start to sound an alarm.

[0043] For example, such as Figure 1 and Figure 6 As shown, the present invention also includes a bottom plate 3 at the lower end of the main box 1, an extension column 2 connected to the bottom of the main box 1 near the corner, a bottom column 4 at the top of the bottom plate 3 corresponding to the extension column 2, and the extension column 2 and the bottom column 4 connected by a column spring 5 on the outside, the diameter of the column spring 5 being greater than 30mm.

[0044] During use, the base column 4, column spring 5 and extension column 2 provide a certain buffer when the main housing 1 is hoisted and placed on the installation surface, preventing damage to the internal structure of the main housing 1.

[0045] For example, such as Figure 1 and Figure 6 As shown, the present invention also includes a reserved groove 9 through the bottom of the base plate 3, a support frame 10 between the inner walls of the reserved groove 9, and strip grooves 6 near the corners of the bottom of the base plate 3.

[0046] In use, the reserved groove 9 and the support frame 10 can reduce the material usage of the base plate 3 while maintaining a certain strength. The base plate 3 can be easily installed by passing external bolts through the strip groove 6.

[0047] In use, this utility model facilitates the routing of cables connecting the internal electrical structure of the main enclosure 1 to the external circuitry through the wiring groove 24 inside the main enclosure 1. The basic functions of a substation are achieved through the low-voltage enclosure 31, the transformer 26, and the high-voltage enclosure 25.

[0048] Temperature sensor 30 is used to conveniently monitor the temperature inside the main enclosure 1. When the temperature exceeds the set value, controller 27 controls the control circuit of alarm 23 to be powered on, thereby causing alarm 23 to sound.

[0049] The base column 4, columnar spring 5, and extension column 2 provide a certain degree of cushioning when the main housing 1 is hoisted and placed on the installation surface, preventing damage to the internal structure of the main housing 1.

[0050] By utilizing the pre-reserved groove 9 and the support frame 10, the material usage of the base plate 3 can be reduced while maintaining a certain level of strength.

[0051] A horizontal plate 14 spans the top of the main housing 1. Triangular plates 18 are connected to the two sides of the main housing 1 near the top corners. The connecting ears 19 at both ends of the triangular plates 18 are connected to the U-shaped connecting frames 17 welded to the top and bottom of the horizontal plate 14 via pins 20. The fixing column part of the lifting ring 13 is connected to the connecting piece 32 on one side of the horizontal plate 14. The connecting plate 12 at the bottom of the lifting ring 13 is connected to the top of the main housing 1, forming an overall reinforced structure. This can greatly improve the overall strength of the lifting ring 13, so that the substation has a reinforced structure when in use, improving the safety during hoisting.
