Description

Technical Field

[0001] The present invention relates to the technical field of substations, and particularly to a modular prefabricated cabin for a substation and a substation. Background Art

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

[0003] To solve the above problems, prefabricated cabin substations with a prefabricated cabin structure 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 corridors, suspended ceilings, air ducts, stairs, and air conditioners are also integrated.

[0004] Traditional prefabricated cabin substations mostly adopt a single-layer flat layout or a double-layer layout. When facing a substation scheme with 3 main transformers or more, the floor area is large, and the improvement of the factory prefabrication degree reaches a bottleneck. Moreover, the current grid-shaped separation method and bottom lifting mode of the traditional prefabricated cabin substation can no longer meet the requirements of the optimal module division, optimal factory prefabrication, optimal transportation cost, and optimal on-site construction.

[0005] The above information disclosed 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

[0006] In view of the problems pointed out in the background art, the present invention proposes a modular prefabricated cabin for a substation and a substation, which improves the factory prefabrication degree of the prefabricated cabin and realizes the optimal module division, optimal factory prefabrication, optimal transportation cost, and optimal on-site construction.

[0007] To achieve the above invention object, the present invention is implemented by adopting the following technical solutions:

[0008] The present invention provides a modular prefabricated cabin for a substation. The prefabricated cabin has one or more layers, and each layer of the prefabricated cabin is horizontally spliced by a plurality of electrical equipment modules and a plurality of auxiliary function modules divided according to functions;

[0009] Each of the electrical equipment modules and each of the auxiliary function modules are respectively prefabricated and wired in the factory, and each is used as an independent transportation and installation unit;

[0010] Each of the electrical equipment modules and each of the auxiliary function modules is installed by means of top lifting.

[0011] In some embodiments of the present application, a plurality of symmetrically arranged lifting parts are provided on the top of each of the electrical equipment modules and each of the auxiliary function modules.

[0012] In some embodiments of the present application, the sizes of each of the electrical equipment modules and each of the auxiliary function modules are standard modular sizes;

[0013] The standard modular size = the minimum size among the electrical equipment modules and the auxiliary function modules + an integer multiple of the reference modular size, and the reference modular size is a preset fixed value.

[0014] In some embodiments of the present application, the electrical equipment module includes:

[0015] A cabin, inside which a support frame barrel structure is provided, and at least one of a bus duct, a cable duct, and a pressure relief duct is provided in the internal space surrounded by the support frame barrel structure;

[0016] Electrical equipment, which is arranged inside the cabin.

[0017] In some embodiments of the present application, the support frame barrel structure includes two relatively arranged support wall frames, a connecting beam is provided between the two support wall frames, the bottom of the support wall frame is connected to the base of the cabin, and the top of the support wall frame is connected to the top beam of the cabin;

[0018] The bus duct, the cable duct, and the pressure relief duct are all arranged inside the support wall frame.

[0019] In some embodiments of the present application, a first side sealing plate is provided on the outer side of the support wall frame for shielding the internal installation space of the support frame barrel structure;

[0020] A detachable sealing plate for sealing the bus duct and the pressure relief duct is provided on the first side sealing plate.

[0021] In some embodiments of the present application, the auxiliary function module includes a corridor integration module, the bottom of which is provided with a floor and the top is provided with a ceiling, and an air duct and / or a bus bridge are provided in the space between the ceiling and the top beam of the corridor integration module.

[0022] In some embodiments of the present application, the auxiliary function module includes a stair environmental control integration module, the inside of which is separated into an environmental control compartment and a stair compartment by a partition structure, an air conditioning device is provided in the environmental control compartment, and a stair is provided in the stair compartment.

[0023] In some embodiments of the present application, a partition structure is provided in each prefabricated cabin, and the partition structure can be slidably arranged along the length or width direction of the prefabricated cabin;

[0024] The partition structure includes a door - type partition and a support - type partition.

[0025] The present invention also provides a substation, including the modular prefabricated cabin as described above.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are:

[0027] The prefabricated cabin disclosed in the present application divides the electrical equipment module and the auxiliary function module according to functions. The electrical equipment module and the auxiliary function module can be arbitrarily combined and arranged according to user needs.

[0028] Both the electrical equipment module and the auxiliary function module are prefabricated and wired in the factory, and then transported to the customer site as a transportation unit, and then spliced as an independent installation unit, which greatly improves the degree of factory prefabrication of the prefabricated cabin, and realizes the optimal module division, the optimal factory prefabrication, the optimal transportation cost, and the optimal on - site construction.

[0029] One form of the electrical equipment module in the present application only includes electrical equipment and does not include other auxiliary function modules such as corridors. Another form includes electrical equipment and corridor modules. Their common feature is that 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 in the factory effectively guarantees the product quality, and avoids the technical problems of large on - site wiring workload and difficult wiring quality control in the prior art.

[0030] The support structure in the electrical equipment module not only plays the role of improving the structural strength, but also integrates the functions of wire routing and pressure relief, which helps to improve the internal structural compactness and further reduce the floor area of the cabin.

[0031] The present application standardizes the interfaces between modules, the module sizes are standardized and modularized, so that each module has strong interchangeability and the feasibility of factory prefabrication.

[0032] The size of each electrical equipment module and each auxiliary function module is a standard modular size. By setting the standard modular size, the module can conveniently and quickly meet the increase in substation equipment expansion and operation and maintenance and repair space by increasing the number of modules, while reducing the types of modules.

[0033] In the present application, each module adopts the method of top - lifting and bottom - positioning to achieve rapid splicing and installation, improving the on - site installation efficiency and reliability.

[0086] Embodiment 1

[0087] [Modular prefabricated cabin]

[0088] This embodiment discloses a modular prefabricated cabin for a substation. The prefabricated cabin can be single-story, Figure 1 as shown; or it can be multi-story, such as Figure 2 and Figure 3 shown, Figure 2 and Figure 3 which are two different forms of three-story layout methods.

[0089] Each layer of the prefabricated cabin is formed by splicing a plurality of electrical equipment modules and a plurality of auxiliary function modules divided according to functions in the horizontal direction.

[0090] Each electrical equipment module and each auxiliary function module are respectively prefabricated and wired in the factory, and are respectively used as an independent transportation and installation unit.

[0091] Each electrical equipment module and each auxiliary function module are installed by means of top hoisting.

[0092] The electrical equipment module is the core module of the prefabricated cabin, which integrates the main electrical equipment of the substation, such as high-voltage equipment, medium-voltage equipment, low-voltage equipment, secondary equipment, bus bridges, etc.

[0093] The electrical equipment module can be a high-voltage equipment module, a medium-voltage equipment module, a low-voltage equipment module, a secondary equipment module, etc.

[0094] The auxiliary function module is a non-core module of the prefabricated cabin, which integrates the auxiliary equipment and functions of the substation, such as corridors, stairs, lighting, air conditioning, air ducts, floors, wall panels, suspended ceilings, etc.

[0095] The auxiliary function module can be a corridor module, a stair module, an environmental control module, etc.

[0096] The electrical equipment module and the auxiliary function module can be arranged randomly according to user needs.

[0097] This application divides the electrical equipment module and the auxiliary function module according to functions.

[0098] One form of the electrical equipment module in this application only includes electrical equipment and does not include other auxiliary function modules such as corridors. Another form includes electrical equipment and corridor modules. Their common feature is that the electrical equipment is highly integrated in the same module cabin, and prefabrication and wiring are completed in the factory. The sound production quality inspection mechanism in the factory effectively guarantees the product quality and avoids the technical problems of large on-site wiring workload and difficult wiring quality control in the prior art.

[0099] Similarly, the auxiliary function module can highly integrate the structures for realizing auxiliary functions in the same module cabin, and prefabrication and wiring are completed in the factory.

[0100] The setting of the electrical equipment core module and the auxiliary function non-core module can bring the following beneficial effects:

[0101] The traditional division method of the prefabricated cabin is in the shape of a Chinese character "mu". Taking Figure 4 one of the layout methods of the single-layer prefabricated cabin shown as an example for the "mu" shape division, among the multiple modules formed by the division, except for the unit module R on the side only including corridor 11, each of the other unit modules R includes electrical equipment 200 and corridor 11. The "mu" shape division method makes these electrical equipment in different segmented modules, resulting in the primary and secondary connections between the equipment can only be completed after on-site cabin splicing. The on-site workload is large, the equipment integration degree is not high, and the quality problems are difficult to control.

[0102] However, this application adopts a new form of division according to function modules. Referring to Figure 5, each row of corridors 11 is divided into an independent corridor module R2, and each row of electrical equipment 200 is divided into an independent electrical equipment module R1, so that the electrical equipment 200 is highly integrated in the same electrical equipment module R1, and the production and assembly of each electrical equipment module R1 and corridor module R2 are first completed in the factory, and then the unit modules are transported to the customer site for splicing, which greatly reduces the workload at the customer site and improves the on-site assembly efficiency.

[0103] Figure 5 Only a specific layout of the prefabricated cabin including electrical equipment 200 and corridor 11 is shown. In actual application, electrical equipment modules with different functions (such as high-voltage electrical equipment modules, medium-voltage electrical equipment modules, low-voltage electrical equipment modules, etc.) and auxiliary function modules (such as corridor modules, staircase modules, environmental control modules, etc.) can be arbitrarily combined according to customer needs to achieve the effects of optimal segmentation, optimal factory prefabrication, optimal transportation cost, and optimal on-site construction.

[0104] The present application standardizes the interfaces between modules, standardizes and modularizes the module sizes, so that the modules have strong interchangeability and the feasibility of factory prefabrication.

[0105] The size of each electrical equipment module and each auxiliary function module is a standard modular size. Through the setting of the standard modular size, the module can be easily and quickly increased by increasing the number of modules to meet the needs of substation equipment expansion and operation and maintenance space increase, while reducing the types of modules.

[0106] Standard module size = minimum size of each electrical equipment module and auxiliary function module + integer multiples of the reference module size. The reference module size is a pre-set fixed value. The reference module is calculated based on the actual size of the prefabricated cabin and substation.

[0107] The introduction of standard modules and benchmark modules makes the cabin shape standardized to the greatest extent possible, thus realizing the prefabricated production of modules.

[0108] In some embodiments of the present application, a plurality of symmetrically arranged hoisting parts are provided on the top of each electrical equipment module and each auxiliary function module, so that a top hoisting installation method of each module is also realized.

[0109] In conjunction with the top hoisting method, a positioning structure 300 is installed at the bottom of each module to achieve rapid positioning and splicing of each module, thereby improving on-site installation efficiency and reliability. The specific structure of the positioning structure 300 will be described in detail below.

[0110] In some embodiments of the present application, each module includes a cabin body 100, which consists of a base 110 and a top beam 120 to form a cabin frame. According to different requirements of the module, different types and structures of support structures are provided between the base 110 and the top beam 120.

[0111] [Electrical equipment core module, support frame tube structure]

[0112] Regarding the specific structure of the electrical equipment module, in some embodiments of the present application, with reference to Figure 6 , the electrical equipment module includes a cabin body 100 and electrical equipment 200 disposed inside the cabin body 100.

[0113] The cabin body 100 is a frame structure assembled by welding profiles and / or plates. Inside the cabin body 100, a vertical support frame tube structure 130 is provided. In the internal space surrounded by the support frame tube structure 130, at least one of a busbar channel 141, a cable channel 142, and a pressure relief channel 143 is provided.

[0114] The electrical equipment module composed of the cabin body 100 and the electrical equipment 200 is transported to the customer site as an independent transportation unit to complete the splicing with other electrical equipment modules or auxiliary function modules.

[0115] The support frame tube structure 130 not only plays a role in improving the overall structural strength of the cabin body 100, but also integrates the functions of wire routing and pressure relief, which helps to improve the internal structural compactness of the cabin body 100 and further reduce the floor area of the cabin body.

[0116] The busbar channel 141, the cable channel 142, and the pressure relief channel 143 are reasonably selected and configured according to the type of electrical equipment 200 installed inside the cabin body 100. For example, the pressure relief channel 143 is only required to be configured when medium-voltage equipment is installed inside the cabin body 100.

[0117] It should be noted that the entire internal space surrounded by the support frame tube structure 130 can be regarded as a cable channel.

[0118] When the prefabricated cabin has a multi-layer layout, the installation spaces on the support frame tube structures 130 of the upper and lower layers are connected, which is convenient for wire routing of electrical equipment between the upper and lower layer cabins, and is more conducive to the assembly of the modular prefabricated cabin, improving the production and assembly efficiency.

[0119] According to the length of the cabin body 100, multiple support frame tube structures 130 can be provided along the length direction of the cabin body 100 to meet the strength support requirements. Figure 6 In the shown structure, there are three support frame tube structures 130, and the electrical equipment 200 is disposed between two adjacent support frame tube structures 130.

[0120] Regarding the specific structure of the cabin body 100, in some embodiments of the present application, with reference toFigure 6 The support frame tube structure 130 is connected between the base 110 and the top beam 120 of the cabin body, and the electrical equipment 200 is slidably arranged on the base 110.

[0121] Taking medium and low voltage electrical equipment as an example, referring to Figure 5 , the dimension W1 of the electrical equipment 200 in 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 direction to realize the position adjustment of each electrical equipment 200, which is convenient for installation.

[0122] Regarding the specific structure of the sliding installation of the electrical equipment, in some embodiments of the present application, referring to Figure 9 , a slide rail 410 is provided on the base 110. The slide rail 410 extends along the cabinet width W2 direction of the electrical equipment. The bottom of the cabinet body of the electrical equipment 200 is slidably arranged in the slide rail 410 through a plastic wing nut 420. By sliding the plastic wing nut 420 along the slide rail 410, the sliding adjustment of the electrical equipment 200 is realized.

[0123] The top beam 120 integrates ceiling decoration (not shown). The ceiling decoration includes a mounting beam and a ceiling decorative panel. The mounting beam is fixed to the frame of the top beam 120. The ceiling decorative panel adopts a modular design. It is first assembled into pieces and then integrally installed on the mounting beam, so as to be integrally integrated onto the top beam 120 to form the ceiling decoration.

[0124] 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 can be fixedly connected. At this time, the bottom of the support frame tube structure 130 is fixedly connected to the base 110 through bolts.

[0125] The support frame tube structure 130 and the base 110 can also be slidably connected (this connection method is not shown). At this time, a chute is provided on the base 110, and the bottom of the support frame tube structure 130 can be slidably arranged in the chute through a plastic wing nut.

[0126] The sliding connection method is convenient for adjusting the position of the support frame tube structure 130 to match electrical equipment of different sizes.

[0127] Generally, the support frame tube structures 130 arranged at both ends of the electrical equipment module generally adopt a fixed connection method, while the support frame tube structures 130 located in the middle can adopt a sliding connection method.

[0128] In some embodiments of the present application, referring to Figure 7 and Figure 8, the support frame-tube structure 130 includes two relatively arranged support wall frameworks 131, and each support wall framework 131 is formed by welding or assembling metal profiles. A connecting beam 132 is provided between the two support wall frameworks 131. The bottom of the support wall framework 131 is connected to the base 110, and the top of the support wall framework 131 is connected to the top beam 120.

[0129] The busbar channel 141, the cable channel 142, and the pressure relief channel 143 are all fixedly arranged inside the support wall framework 131.

[0130] Further, 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 corner positions of the two support wall frameworks 131 and has an L-shaped structure, which plays a role in connecting and fixing both the top and side parts of the support wall framework 131. A plurality of second connecting beams 1322 are provided between the two first connecting beams 1321.

[0131] The first connecting beam 1321 and the second connecting beam 1322 are formed by sheet metal bending or profile welding and are fixed to the support wall framework 131 by bolts or welding.

[0132] Further, an angle support plate 133 is welded between the horizontal beam and the vertical beam constituting the support wall framework 131 to further improve the structural strength.

[0133] Further, a plurality of symmetrically distributed lifting rings 190 are provided at the top of the support wall framework 131 to facilitate top lifting by a lifting tool and facilitate installation.

[0134] Further, a first side sealing plate 161 is provided on the outer side of the support wall framework 131 to block the internal installation space of the support frame-tube structure 130.

[0135] The first side sealing plate 161 is made of metal sheet metal by painting or spraying and is fixed to the outer side of the support wall framework 131 by bolts or welding.

[0136] Further, a detachable sealing plate 180 is provided on the first side sealing plate 161, and the detachable sealing plate 180 is used to block the busbar channel 141 and the pressure relief channel 143. The one facing the busbar channel 141 is defined as the first detachable sealing plate 181, and the one facing the pressure relief channel 143 is defined as the second detachable sealing plate 182.

[0137] The detachable sealing plate 180 is also made of metal sheet metal or spraying and is installed on the support wall framework 131 by bolts.

[0160] Of course, in other embodiments, the location and direction of the corridor integration module 800 can be flexibly arranged according to needs.

[0161] More specifically, the corridor integrated module 800 can be integral or split.

[0162] The integral corridor integration module means that there is a support upright frame between the base 110 and the top beam 120 of the corridor integration module. The base 110, the top beam 120, the support columns, the ceiling 820, the air duct 830, the bus duct 840, etc. are prefabricated and wired in the factory first, and then transported to the customer site as a complete transportation unit, and then spliced with other modules, greatly shortening the on-site installation time and improving the on-site installation efficiency.

[0163] The split corridor integration module means that there is no support upright frame connecting the base 110 and the top beam 120 of the corridor integration module. In the factory prefabrication stage, the floor 810 and the base 110 are first assembled to form an independent unit, and then the top structures such as the top beam 120, the ceiling 820, the air duct 830, the bus duct 840, etc. are assembled to form another independent unit, and then these two parts of the unit are transported in a multi-layer stacking manner, saving transportation vehicles and transportation costs. After arriving at the customer site, the above two independent units are spliced with other surrounding modules by means of bolt penetration, etc., and then the on-site installation of the split corridor integration module is completed.

[0164] The second auxiliary function module is the stair environmental control integration module 900. Refer to Figure 25 , which also forms a cabin structure by a base, a top beam and a circumferential support frame. Inside it, it is separated into an environmental control compartment 910 and a stair compartment 920 by a partition structure 600. An air conditioning device 911 is provided in the environmental control compartment 910, and a stair 921 is provided in the stair compartment 920.

The bottom of each module is provided with the positioning structure 300, and the top of each module is provided with a lifting part 500.

[0168] The lifting part 500 can be a lifting lug / and or a lifting ring, and the lifting point positions are symmetrically distributed to ensure the balance of each module during lifting. At the same time, the present application also innovatively introduces auxiliary lifting points, and the lifting balance is further improved by adding auxiliary lifting points during lifting.

[0169] For the specific structure of the positioning structure 300, in some embodiments of the present application, refer to Figures 10 to 12 , among which, Figure 10In the shown structure, two electrical equipment modules can be spliced together, or an electrical equipment module can be spliced with other auxiliary function modules. For the convenience of description, the two spliced modules are defined as the first module M1 and the second module M2.

[0171] During splicing, first install the positioning member 310 onto one of the modules to be spliced (such as the first module M1), and make one of the guiding columns 313 pass through the guiding hole 321 on the corresponding module (i.e., the first module M1). Then, insert the guiding holes 321 on the remaining modules to be spliced (i.e., the second module M2) corresponding to the remaining guiding columns 313. With the cooperation of hoisting at the top, the quick splicing of two adjacent modules can be easily completed.

[0172] Specifically, the positioning member 310 includes a substrate 311, a connecting portion 312, and guiding columns 313. The connecting portion 312 is vertically arranged at the middle position of the substrate 311.

A plurality of guiding columns 313 are vertically arranged on the substrate 311, and the plurality of guiding columns 313 are respectively located on both sides of the connecting portion 312 for positioning and connecting between adjacent cabin bodies.

[0173] For the convenience of processing, the substrate 311, the connecting portion 312, and the guiding columns 313 are connected by welding. Of course, other assembly forms such as bolt connection can also be used. Only one implementation method is proposed here and is not specifically limited.

[0174] The guiding member 320 is in a plate-like structure and is horizontally formed at the bottom of the module cabin body. Guiding holes 321 are formed on the guiding member 320. During the positioning process, the guiding columns 313 penetrate into the corresponding guiding holes 321 to achieve the splicing between adjacent modules.

[0175] A second connecting hole 322 is formed on the bottom side wall of the module cabin body. In the installed state, the second connecting hole 322 corresponds to the first connecting hole 314. The bolt 330 passes through the first connecting hole 314 and the second connecting hole 322 to fix the positioning member 310 on the module cabin body.

[0176] Figures 10 to 12 In the shown structure, there are two guiding columns 313 on the positioning member for the splicing of two adjacent modules.

[0177] If four adjacent modules need to form a cross-shaped splicing, four guiding columns 313 need to be provided on the required positioning member 310. Refer toFigure 12 , the installation process can refer to the splicing process of the two modules, which will not be elaborated here.

[0178] For the splicing of the upper and lower modules, refer to Figure 14 , install the positioning part 310 at the top of the lower module K1 cabin body, install the guiding part 320 at the bottom of the upper module K2 cabin body, and through the positioning of the positioning part 310 and the guiding part 320, the rapid splicing of the upper and lower modules can be realized.

[0192] Furthermore, arc-shaped bending parts 721 bent inwardly towards the inside of the C-shaped slide rail are respectively provided at the bottom ends of the two side surfaces of the C-shaped slide rail. When the upper module K2 is placed on the top of the lower module K1, the bottom of the arc-shaped bending part 721 abuts against the first fixed beam 710. When the upper cabin needs to adjust its position, the arc-shaped structure facilitates movement along the first fixed beam 710.

[0193] The nut 732 is a riveted nut, which is riveted to the top of the first abutting wall 7311 and becomes an integral body with the anti-rotation part 731.

[0194] The fastener 740 is a bolt, and a gasket 750 is provided between the fastener 740 and the first fixed beam 710 to reduce local stress and improve the structural reliability.
