Description

Technical Field

[0001] The present invention relates to the technical field of substations, and in particular to a prefabricated cabin electrical equipment module, a prefabricated cabin and a substation. Background Art

[0002] Traditional substations are generally of the civil engineering mode and need to be constructed on site, which has disadvantages such as long construction periods, great impact on the surrounding environment, and large floor areas. With the increasing tension of urban land and the continuous increase of residential density, there are problems such as affecting the normal life of residents and the surrounding living environment when building new substations in the city center. In addition, when building substations in harsh environments such as high altitudes, there are also problems such as long construction periods, poor environments, difficult construction, and high labor intensity of personnel.

[0003] To solve the above problems, prefabricated cabin substations with prefabricated cabin structures are widely used. High-voltage equipment, low-voltage equipment, secondary equipment, bus bridges and other electrical equipment are integrated in the prefabricated cabin, and auxiliary equipment such as air ducts, stairs, and air conditioners are also integrated. The internal structure of the prefabricated cabin is compact, which can effectively reduce the floor area.

[0004] Currently, referring to Figure 1 , the division method of the prefabricated cabin substation is the "mu" - shaped division. Among the multiple modules formed by the division, except for the unit module R on the side only including the corridor 12, each of the other unit modules R includes electrical equipment 11 and the corridor 12. The "mu" - shaped division method makes these electrical equipment in different segmented modules, resulting in the fact that the primary and secondary connections between the equipment can only be completed after the on - site cabin splicing. The on - site workload is large, the equipment integration degree is not high, and it is difficult to control the quality problems.

[0005] The above - disclosed information in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention

Example 1

[0066] This embodiment discloses an electrical equipment module for use in a prefabricated cabin.

[0067] Reference Figure 3 The electrical equipment module includes a cabin 100 and electrical equipment 200 arranged in the cabin 100.

[0068] The electrical equipment 200 may be high voltage equipment, medium voltage equipment, low voltage equipment, secondary equipment, bus bridge, etc.

[0069] The cabin body 100 is a frame structure assembled by welding profiles and / or plates. The cabin body 100 includes a vertical support frame structure 130. At least one of a bus channel 141, a cable channel and a pressure relief channel 143 is provided in the internal space surrounded by the support frame structure 130.

[0070] The electrical equipment module only includes electrical equipment, and does not include other auxiliary function modules such as corridors. The electrical equipment is highly integrated in the same cabin, and prefabrication and wiring are completed in the factory. The sound production quality inspection mechanism within the factory is used to effectively ensure product quality, avoiding the technical difficulties in existing technologies that require customers to conduct on-site wiring, with a large workload and difficult to control wiring quality.

[0071] The electrical equipment module consisting of the cabin 100 and the electrical equipment 200 is then transported to the customer site as an independent transport unit to be assembled with other electrical equipment modules or auxiliary function modules (such as corridor modules, staircase modules, etc.).

[0072] The support frame tube structure 130 not only improves the overall structural strength of the cabin 100, but also integrates the functions of wiring and pressure relief, which helps to improve the structural compactness of the interior of the cabin 100 and further reduce the footprint of the cabin.

[0073] The bus channel 141, the cable channel and the pressure relief channel 143 are reasonably selected and configured according to the type of electrical equipment 200 installed in the cabin 100. For example, the pressure relief channel 143 is only required when medium voltage equipment is installed in the cabin 100.

[0074] It should be noted that the entire internal space enclosed by the supporting frame tube structure 130 can be regarded as a cable channel.

[0075] When the prefabricated cabin is arranged in multiple layers, the installation spaces on the upper and lower support frame tube structures 130 are connected, which facilitates the routing of electrical equipment between the upper and lower cabin bodies, is more conducive to the assembly of modular prefabricated cabins, and improves production and assembly efficiency.

[0076] According to the length of the cabin body 100, multiple support frame barrel structures 130 can be provided along the length direction of the cabin body 100 to meet the strength support requirements. Figure 3 In the shown structure, there are three support frame barrel structures 130, and the electrical equipment 200 is arranged between two adjacent support frame barrel structures 130.

[0077] The electrical equipment module in this embodiment is formed based on the design concept of dividing the prefabricated cabin according to functional modules.

[0078] Specifically, taking Figure 1 the shown prefabricated cabin as an example, the prefabricated cabin includes two rows of electrical equipment 11 and four rows of corridors 12. The final layout structure is that one row of corridors 12 is located at the end side, and the other three rows of corridors 12 are interspersed between the two rows of electrical equipment 11. According to the existing "mu" - shaped division form, except for the corridor module at the outermost end side, each of the other divided unit modules R includes electrical equipment 11 and corridors 12. The electrical equipment 11 is divided into different segmented unit modules R, resulting in that the primary and secondary connections between the equipment can only be completed after the on - site cabin splicing. The on - site workload is large, the equipment integration level is not high, and it is difficult to control the quality problems.

[0079] [[ID=​​​​​​​​​​​​​​ Figure 2 The dimension W1 of the electrical equipment 200 along the cabinet depth direction is generally fixed, while the cabinet width dimension W2 of the electrical equipment 200 is variable. The electrical equipment 200 can slide along the cabinet width W2 to adjust the position of each electrical equipment 200 for easy installation.

[0083] For the specific structure of the sliding installation, in some embodiments of the present application, refer to Figure 6 A slide rail 410 is provided on the base 110, and the slide rail 410 extends along the cabinet width W2 of the electrical equipment. The bottom of the cabinet of the electrical equipment 200 is slidably arranged in the slide rail 410 through the plastic wing nut 420. The sliding adjustment of the electrical equipment 200 is realized by sliding the plastic wing nut 420 along the slide rail 410.

[0084] The top support portion 120 is integrated with a suspended ceiling decoration (not shown). The suspended ceiling decoration includes a mounting beam and a suspended ceiling decorative panel. The mounting beam is fixed to the frame of the top support portion 120. The suspended ceiling decorative panel can be a sheet metal suspended ceiling panel, an aluminum honeycomb suspended ceiling panel, an aluminum square tube suspended ceiling panel, etc. The suspended ceiling decorative panel adopts a modular design. It is first assembled into pieces and then installed as a whole on the mounting beam, thereby being integrated as a whole into the top support portion 120 to form a suspended ceiling decoration.

[0085] Regarding the specific structure of the support frame tube structure 130 , in some specific embodiments of the present application, the support frame tube structure 130 and the base 110 of the cabin body can be fixedly connected. In this case, the bottom of the support frame tube structure 130 is fixedly connected to the base 110 by bolts.

[0086] The support frame tube structure 130 and the base 110 can also be connected by sliding (this connection method is not shown in the figure). In this case, a slide groove is provided on the base 110, and the bottom of the support frame tube structure 130 can be slidably arranged in the slide groove through a plastic wing nut.

[0087] The sliding connection method facilitates adjustment of the position of the support frame structure 130 to match electrical equipment of different sizes in the cabin 100 .

[0088] Typically, the support frame tube structures 130 disposed at both ends of the cabin body 100 generally adopt a fixed connection method, while the support frame tube structure 130 located in the middle of the cabin body 100 can adopt a sliding connection method.

[0089] In some embodiments of this application, refer to Figure 4 and Figure 5 The support frame tube structure 130 includes two opposing support wall frames 131, each welded from metal profiles. A connecting beam 132 is provided between the tops of the two support wall frames 131.

[0091] Furthermore, the connecting beam 132 includes a first connecting beam 1321 and a second connecting beam 1322. The first connecting beam 1321 is arranged at the top corners of the two supporting wall frames 131 and has an L-shaped structure. It plays a connecting and fixing role on the top and side of the supporting wall frame 131. Multiple second connecting beams 1322 are arranged between the two first connecting beams 1321.

[0092] The first connecting beam 1321 and the second connecting beam 1322 are formed by bending and welding sheet metal, and are fixed to the supporting wall frame body 131 by bolts or welding.

[0093] Furthermore, angle support plates 133 are welded between the transverse beams and vertical beams constituting the support wall frame body 131 to further improve the structural strength.

[0094] Furthermore, a plurality of symmetrically distributed lifting rings 190 are provided on the top of the supporting wall frame body 131 to facilitate top lifting by a lifting device for easy installation.

[0095] Furthermore, a first side sealing plate 161 is provided on the outer side of the supporting wall frame body 131 to shield the internal installation space of the supporting frame tube structure 130 .

[0096] The first side sealing plate 161 is made of a metal sheet that is spray-painted or plastic-sprayed, and is fixed to the outer side of the supporting wall frame body 131 by bolts or welding.

[0097] Furthermore, a removable sealing plate 180 is provided on the first side sealing plate 161, and the removable sealing plate 180 is used to block the bus channel 141 and the pressure relief channel 143. The first removable sealing plate 181 is defined as facing the bus channel 141, and the second removable sealing plate 182 is defined as facing the pressure relief channel 143.

[0098] The detachable cover plate 180 is also made of sheet metal or plastic spraying and is mounted on the supporting wall frame 131 by bolts.

[0099] When the electrical equipment module does not need busbar routing, the busbar channel 141 is blocked by the first detachable sealing plate 181; and when the cabin 100 needs busbar routing, the first detachable sealing plate 181 is removed.

[0100] When the electrical equipment module does not need to relieve pressure, the pressure relief channel 143 is blocked by the second detachable sealing plate 182 ; and when the cabin 100 needs to relieve pressure, the second detachable sealing plate 182 is removed.

[0101] Furthermore, the sides of the two supporting wall frames 131 are provided with a second side sealing plate 162 and a door body 170 arranged up and down.

[0102] The second side sealing plate 162 is made of a metal sheet that is spray-painted or plastic-sprayed, and is fixed to the supporting wall frame body 131 by bolts or welding, so as to connect the two supporting wall frame bodies 131 .

[0103] The second side sealing plate 162 is provided with an opening 1621 communicating with the pressure relief channel 143 to achieve pressure relief.

[0104] The door body 170 can be a single-door or double-door type, which is convenient for operators to enter the support frame tube structure 130 to perform line maintenance, etc.

[0105] Furthermore, a plurality of cable brackets 150 are provided on the inner side of the supporting wall frame body 131 , and the cable brackets 150 are provided with fixing holes 151 for fixing cables.

[0106] The cable bracket 150 is made of metal profiles or hot plate welding, and a flange (not marked) is welded on the end side of the profile. The flange is fixed to the supporting wall frame body 131 by bolts or welding.

[0107] The number and installation positions of the cable supports 150 can be specifically set according to wiring requirements.

[0108] Furthermore, a wiring trough 142 is provided on the inner side of the supporting wall frame 131. The wiring trough 142 is formed by bending a metal plate, and the surface can be painted or sprayed with plastic. It includes a wiring trough body and a wiring trough cover. The wiring trough body and the wiring trough cover are fixed by bolts. The wiring trough 142 as a whole can be fixed to the supporting wall frame 131 by bolts or welding.

[0109] A cable climbing frame is designed inside the cable duct to fix the secondary cables.

[0110] The number and installation positions of the wiring troughs 142 can be specifically set according to wiring requirements.

[0111] The cable support 150 and the wiring trough 142 are used for routing different types of wires.

[0112] Regarding the specific structure of the bus channel 141, in some embodiments of the present application, the bus channel 141 is assembled from busbar panels formed by bending stainless steel plates, and the busbar panels and the busbar panels and the supporting wall frame 131 are fixed by bolts.

[0113] Furthermore, an insulator bracket (not shown) is provided in the bus channel 141 for installing and fixing the insulators of the copper busbar.

[0114] The bus channel 141 can realize the through connection of the copper bars of the switch cabinet equipment on both sides of the supporting frame tube structure and has an anti-eddy current function.

[0116] The pressure relief channel 143 can penetrate the switch cabinet pressure relief channels on both sides of the support frame tube structure 130 and guide the cabinet pressure relief to the outside of the cabin through the support frame tube structure.

[0117] In order to further improve the on-site installation efficiency, in some embodiments of the present application, multiple electrical equipment modules are spliced ​​in the horizontal direction through a positioning structure 300, a positioning structure 300 is provided at the bottom of the cabin 100, and a lifting part 500 is provided at the top of the cabin 100.

[0118] This application overturns the original bottom hoisting method. The electrical equipment modules are quickly spliced ​​by top hoisting and bottom positioning, thereby improving on-site installation efficiency and reliability.

[0119] Of course, electrical equipment and other adjacent auxiliary function modules (such as corridor modules, stair modules, etc.) also use the same positioning structure for rapid splicing.

[0120] The hoisting portion 500 may be a lifting lug or a lifting ring, and the lifting points are symmetrically distributed to ensure the balance of the cabin 100 during hoisting. At the same time, the present application also innovatively introduces auxiliary lifting points to further improve the hoisting balance by adding auxiliary lifting points during hoisting.

[0121] For the specific structure of the positioning structure 300, in some embodiments of the present application, refer to Figures 7 to 9 ,in, Figure 7 The structure shown may be two electrical equipment modules spliced ​​together, or an electrical equipment module spliced ​​together with other auxiliary function modules. For ease of description, the two spliced ​​modules are defined as a first module 1 and a second module 2.

[0122] The positioning structure 300 includes a positioning member 310 and a guide member 320 . The positioning member 310 is provided with a plurality of positioning posts 313 , and the guide member 320 is provided with a guide hole 321 . The guide member 320 is provided at the bottom of the cabin 100 .

[0123] During splicing, the positioning piece 310 is first installed on one of the cabins to be spliced ​​(such as the first module 1), and one of the positioning columns 313 is passed through the guide hole 321 on the corresponding cabin (i.e., the first module 1). Then, the guide holes 321 on the remaining cabins to be spliced ​​(i.e., the second module 2) are correspondingly plugged into the remaining positioning columns 313. With the help of top hoisting, the rapid splicing of two adjacent modules can be easily completed.

[0124] Specifically, the positioning member 310 includes a base plate 311, a connecting portion 312 and a positioning column 313. The connecting portion 312 is vertically arranged in the middle position of the base plate 311. A first connecting hole 314 is formed on the connecting portion 312 for fixing the entire positioning member 310 to the bottom of the cabin. A plurality of positioning columns 313 are vertically arranged on the base plate 311. The plurality of positioning columns 313 are respectively located on both sides of the connecting portion 312 for positioning connections between adjacent cabins.

[0125] For ease of processing, the base plate 311 , the connecting portion 312 and the positioning column 313 are connected by welding. Of course, other assembly forms such as bolt connections may also be used. This is only one implementation method proposed here and is not specifically limited.

[0126] The guide member 320 is a plate-like structure, formed horizontally at the bottom of the cabin. A guide hole 321 is formed on the guide member 320. During the positioning process, the positioning column 313 penetrates into the corresponding guide hole 321 to achieve splicing between adjacent cabins.

[0127] A second connection hole 322 is formed on the bottom side wall of the cabin. In the installed state, the second connection hole 322 corresponds to the first connection hole 314. The bolt 330 passes through the first connection hole 314 and the second connection hole 322 to fix the positioning member 310 on the cabin.

[0128] Figures 7 to 9 In the structure shown, two positioning posts 313 are provided on the positioning member for connecting two adjacent modules.

[0129] If four adjacent modules are required to form a cross-shaped splicing, the required positioning member 310 needs to be provided with four positioning posts 313, referring to Figure 10 The installation process can refer to the splicing process of the two modules, which will not be repeated here. Example 2

[0130] This embodiment discloses a prefabricated cabin, which includes the electrical equipment module and auxiliary function module disclosed in the first embodiment.

[0131] The electrical equipment module may be a high voltage equipment module, a medium voltage equipment module, a low voltage equipment module, a secondary equipment module, etc.

[0132] Auxiliary function modules can be corridor modules, stair modules, environmental control modules, etc.
