[0044] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0045] 1 to 8 , a three-dimensional integrated modular charging station includes: a power distribution module, including a high-voltage power distribution component, a transformer 150 component, and a low-voltage power distribution component 160. The high-voltage power distribution component is suspended above a rack 270. The rack 270 is an open-sided structure with a plurality of mounting rods provided circumferentially around the top of the rack 270. The transformer 150 component is provided on the upper portion of the rack 270. The transformer 150 component includes a high-voltage incoming copper busbar, a transformer 150, and a low-voltage outgoing copper busbar connected in sequence. The high-voltage incoming copper busbar is electrically connected to the output end of the high-voltage power distribution component. The low-voltage power distribution component 160 is provided in the middle portion of the rack 270. The low-voltage power distribution component 160 includes a low-voltage incoming line cabinet 280 and a low-voltage outgoing line cabinet 290. The low-voltage incoming line cabinet 280 is electrically connected to the low-voltage outgoing copper busbar.

[0046] The power module includes a power cabinet 180 and a riser 210. The riser 210 is provided at the bottom of the power cabinet 180. The power cabinet 180 is mounted at the bottom of the rack 270 via the riser 210. The power cabinet 180 is electrically connected to the output end of the low-voltage outlet cabinet 290.

[0047] The load module is arranged on one side of the rack 270 . The load module includes a charging pile 230 and a cable trough 220 . The charging pile 230 is installed on the upper surface of the cable trough 220 . The cable trough 220 is connected to the power cabinet 180 and the charging pile 230 .

[0048] The distribution module is used to convert the high voltage electricity of the overhead line 100 into low AC voltage electricity, and the power module is used to convert the AC power input by the low-voltage outlet cabinet 290 into DC power to supply power to the charging pile 230. Combining the charging pile 230 with the distribution module can facilitate the installation of charging stations in rural areas without the need to bury pipelines, facilitate on-site installation, improve installation efficiency, and have a higher degree of integration.

[0049] 1 to 3 , the high-voltage power distribution components include an insulator 110, a disconnector 120, a drop-out fuse 130, a lightning arrester 140, and a high-voltage metering cabinet 200. These components are mounted on a mounting pole, while the high-voltage metering cabinet 200 is mounted on one side of a transformer 150. This ensures safety during use of the three-dimensional integrated modular charging station.

[0050] The transformer 150 is provided with high-voltage terminals for metering, which are mainly used for connecting to the current transformer and voltage transformer. The current transformer is installed on the current transformer mounting frame of the transformer 150, and the voltage transformer is installed in the high-voltage metering cabinet 200. The back of the high-voltage metering cabinet 200 is installed in contact with the transformer 150. Conventional transformer sets mostly use outdoor integrated combined transformers for high-voltage metering. They are heavy and inconvenient to install. In case of failure, the entire transformer can only be replaced. This solution adopts the form of a single transformer. In case of failure, only the corresponding single transformer needs to be replaced. Moreover, the high-voltage metering cabinet 200 is installed integrally with the transformer set, so that assembly can be completed in the factory.

[0051] The mounting rod is connected to a plurality of crossbars 240, each of which is connected to two opposite mounting rods. The crossbars 240 are spaced apart along the length of the mounting rod, and the insulators 110, disconnectors 120, drop-out fuses, and lightning arresters 140 are sequentially mounted on the corresponding crossbars 240 in a vertically downward direction. The provision of the crossbars 240 facilitates the installation of high-voltage power distribution components and improves installation efficiency.

[0052] The mounting pole is provided with a photovoltaic assembly 190, which is connected to the charging pile 230 via a DC cable. This can save energy.

[0053] Referring to Figures 1, 2 and 5, an energy storage battery cabinet 170 is also provided in the power module. The input end of the energy storage battery cabinet 170 is connected to the photovoltaic component 190, and the output end of the energy storage battery cabinet 170 is connected to the charging pile 230. The energy storage battery cabinet 170 can store the electrical energy generated by the photovoltaic panel, further improving the energy-saving effect. The energy storage battery cabinet 170 and the power cabinet 180 are installed side by side on the lifting base 210. The bottom of the lifting base 210 is provided with a through pipe 320 for forklift transportation. The forklift can facilitate the installation of the power module by directly transporting the through pipe 320. The lifting base 210 is also conducive to the subsequent replacement and maintenance of the power module separately. When replacing and repairing, there is no need to disassemble the entire distribution module equipment, thereby improving efficiency.

[0054] 1 , the upper end of the bracket of the photovoltaic module 190 is shorter than the lower end of the bracket, so that the photovoltaic module 190 can be formed at an inclined angle. When wind blows from both sides, the airflow on both sides will flow upward along the inclined surface of the photovoltaic module 190, thereby accelerating the upward flow of the middle airflow, further enhancing the heat dissipation performance of the transformer 150.

[0055] 2 and 3 , the mounting pole is composed of a plurality of mounting sections 250 , and a plurality of flanges are provided at both ends of the mounting section 250 . The plurality of mounting sections 250 are spliced ​​together through the flanges. In some embodiments, the number of mounting poles is four, of which two mounting poles are composed of two mounting sections 250 , and the other two mounting poles are provided with only one mounting section 250 , so as to facilitate drawing power from the overhead line 100 and avoid the mounting sections 250 affecting the layout of the overhead line.

[0056] 2 and 4 , a top cover 260 is provided on top of the low-voltage power distribution component 160. An outward-turning mounting portion 300 is provided in the middle of the top cover 260. The transformer 150 is secured to the upper portion of the rack 270 via the outward-turning mounting portion 300. Water-guiding slopes 310 are provided on both sides of the top cover 260. Water-guiding holes connect the outward-turning mounting portion 300 and the water-guiding slopes 310. The outward-turning mounting portion 300 facilitates the installation of other modules on top of the low-voltage power distribution component 160. The water-guiding slopes 310 prevent rainwater from accumulating on the top cover 260. The water-guiding holes are slightly higher than the water-guiding slopes 310, facilitating the drainage of accumulated water within the outward-turning mounting portion 300.

[0057] The top cover 260 is triangular in shape, so rainwater will not accumulate on the top cover 260. The copper bus aisle on the symmetrical side of the top cover 260 is non-enclosed. When the transformer 150 is installed above the top cover 260, wind can enter the bottom of the transformer 150 from here and then flow out from the top cover of the transformer 150, forming convection, so that the heat dissipation performance of the transformer 150 is better; at the same time, in order to avoid excessive accumulation of rainwater here, a number of water guide holes are provided between the vertical surface of the outward-turned mounting portion 300 and the water guide slope 310 of the top cover 260 to facilitate the drainage of rainwater.

[0058] Referring to Figure 2 , the rack 270 is provided with a wiring channel 350. The wiring channel 350 is arranged in a vertical direction, with its ends respectively connected to the middle and bottom of the rack 270. The wiring channel 350 not only protects the safety of the cables but also improves waterproofness and installation efficiency. The low-voltage power distribution components 160 and the power supply cabinet 180 are connected through the wiring channel 350.

[0059] Referring to Figure 6 , the cable trough 220 is constructed by splicing multiple trough bodies together. Water guide grooves 340 are provided at the joints of the trough bodies. Water guide flanges 330 are provided at the cable connection ports of the trough bodies. Drain holes are provided at the bottom of the trough bodies to prevent rainwater from accumulating in the trough bodies and improve the safety of the three-dimensional integrated modular charging station.

[0060] The charging pile 230 is installed on the cable trough 220. The cable trough 220 can be a T-shaped structure led out from the middle or from the side. After being led out, its direction can also change according to the layout of the charging parking spaces, which is more convenient for the planning and design of the entire charging station.

[0061] 7 and 8 , the photovoltaic module 190 can be directly connected to the power cabinet 180. A DC-DC converter with MPPT is installed inside the power cabinet 180. This allows the voltage of the electric energy generated by the photovoltaic module 190 to match the voltage required by the power cabinet 180 and can be directly applied to the charging circuit. The photovoltaic module 190 can also convert DC to AC through an inverter and then connect it to the outgoing line cabinet for use by the electrical loads in the charging station, making full use of clean energy and improving the efficiency of the charging station.
