Description

Technical Field

[0001] This utility model relates to the field of substation technology, and in particular to a prefabricated outdoor substation. Background Technology

[0002] Prefabricated outdoor substations, also known as outdoor prefabricated substations or outdoor box-type substations, are compact power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution devices according to a specific wiring scheme. These substations are factory-prefabricated and possess characteristics such as rust prevention, dust prevention, rodent prevention, fire prevention, theft prevention, and heat insulation, making them suitable for outdoor environments. A prefabricated outdoor substation generally consists of four parts: high-voltage switchgear, low-voltage distribution panels, distribution transformers, and the enclosure. These parts are electrically connected via cables or busbars to form a complete power distribution system.

[0003] In outdoor environments, substation air intakes are susceptible to contamination from wind, sand, insects, leaves, and other debris. Without filters, these objects can enter the substation, damaging electrical equipment and wiring, and even causing short circuits. Therefore, installing filters in air intakes is essential. Since substations are installed outdoors, dust accumulates on the filters over time, requiring regular removal and cleaning. However, because air intakes are often located high within the substation enclosure, and the filters are secured to the frame with multiple bolts, disassembly and cleaning are particularly inconvenient. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a prefabricated outdoor substation to solve the shortcomings of existing outdoor substations where the air intake windows are mostly located high up in the substation enclosure, and the filter screens are fixed to the window edge with multiple sets of bolts, making disassembly and cleaning particularly inconvenient.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a prefabricated outdoor substation, including a transformer box, a box eaves on the top of the transformer box, a ventilation window on the front of the transformer box, and an air intake window on the back of the transformer box;

[0006] The back of the transformer box is equipped with a movable plate, and a rotating shaft is provided between the movable plate and the transformer box. The rotating shaft is rotatably connected to the transformer box and fixedly connected to the movable plate. The left and right ends of the movable plate are detachably connected with mounting cylinders.

[0007] A filter screen is detachably connected inside the mounting cylinder. One of the mounting cylinders covers the outside of the air intake window. A positioning device for limiting the movement of the mounting cylinders is provided on the back of the transformer box. The positioning device is located below the other mounting cylinder.

[0008] A further improvement is that a positioning ring is fitted on the outer side of the mounting cylinder, and the positioning ring is fixedly connected to the mounting cylinder.

[0009] A further improvement is that: the movable plate has a slot on the side facing the mounting cylinder, the positioning ring engages with the slot, and the outer side of the movable plate is provided with a bolt connector for fixing the positioning ring.

[0010] A further improvement is that the bolt connector includes a positioning bolt mounted on the outside of the movable plate, the positioning bolt being threadedly connected to the movable plate, the positioning bolt being screwed into the slot and threadedly connected to the first positioning hole opened on the outside of the positioning ring.

[0011] A further improvement is that the positioning device includes a fixed base, which is fixedly connected to the back of the transformer box. A limit rod is slidably provided on the fixed base, and the limit rod passes through the fixed base. A second positioning hole is provided on the side of the positioning ring away from the mounting cylinder. The second positioning hole is slidably connected to the limit rod. A floating plate is provided on the side of the fixed base away from the positioning ring. The floating plate is fixedly connected to the limit rod. A spring is fixedly connected between the floating plate and the fixed base.

[0012] A further improvement is that a handle is provided on the side of the floating plate away from the fixed base, and the handle is fixedly connected to the floating plate.

[0013] A further improvement is that: the edge of the filter screen is provided with at least two locking blocks, the locking blocks are fixedly connected to the filter screen, the locking blocks are slidably connected to the locking groove opened inside the mounting cylinder, and the upper end of the locking block is threadedly connected to a fixing bolt, which is threadedly connected to the bolt hole opened inside the locking groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Gas enters the air intake window through the mounting cylinder. The filter screen inside the mounting cylinder filters the dust in the airflow. There are two mounting cylinders, which are fixed to the end of the movable plate.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a prefabricated outdoor substation, including a transformer box 1. The top of the transformer box 1 is provided with a box eave 3, the front of the transformer box 1 is provided with a ventilation window 2, and the back of the transformer box 1 is provided with an air intake window 4. A ventilation fan is fixedly installed inside the air intake window 4. The ventilation fan draws outside air into the transformer box 1 through the air intake window 4 to ensure normal heat dissipation of electrical components inside the transformer box 1.

[0025] The back of the transformer box 1 is provided with a movable plate 8, and a rotating shaft 9 is provided between the movable plate 8 and the transformer box 1. The rotating shaft 9 is rotatably connected to the transformer box 1 and fixedly connected to the movable plate 8. The left and right ends of the movable plate 8 are detachably connected with mounting cylinders 5.

[0026] A filter screen 6 is detachably connected inside the mounting cylinder 5. One of the mounting cylinders 5 covers the outside of the air inlet window 4. A positioning device for limiting the movement of the mounting cylinder 5 is provided on the back of the transformer box 1. The positioning device is located below the other mounting cylinder 5.

[0027] Gas enters the air intake window 4 through the mounting cylinder 5. The filter screen 6 inside the mounting cylinder 5 filters the dust in the airflow. The movable plate 8 can be rotated to quickly replace the filter screen 6 that is full of dust without disassembling and reassembling it. When the mounting cylinder 5 at the top of the movable plate 8 rotates to the outside of the air intake window 4, the positioning device will limit the mounting cylinder 5 at the top of the movable plate 8, restricting the movable plate 8 from continuing to rotate, and ensuring stable airflow in and out of the mounting cylinder 5.

[0028] It should be noted that a positioning ring 7 is fitted on the outer side of the mounting cylinder 5, and the positioning ring 7 is fixedly connected to the mounting cylinder 5.

[0029] To facilitate the replacement and maintenance of the mounting cylinder 5, a slot 10 is provided on the side of the movable plate 8 facing the mounting cylinder 5. The positioning ring 7 engages with the slot 10. A bolt connector is provided on the outer side of the movable plate 8 to fix the positioning ring 7. When installing the mounting cylinder 5, the positioning ring 7 on the outer side of the mounting cylinder 5 is placed against the end of the movable plate 8. The slot 10 at the end of the movable plate 8 will engage with the positioning ring 7. After engagement, the bolt connector will fix the positioning ring 7 to the movable plate 8, completing the assembly of the mounting cylinder 5.

[0030] More specifically, the bolt connector includes a positioning bolt 12 mounted on the outside of the movable plate 8. The positioning bolt 12 is threaded to the movable plate 8, screwed into the slot 10, and threaded to the first positioning hole 11 on the outside of the positioning ring 7. When the filter screen 6 is removed from the end of the movable plate 8 for replacement, the positioning bolt 12 is simply unscrewed from the first positioning hole 11 on the outside of the positioning ring 7.

[0031] Regarding the positioning device:

[0032] The positioning device includes a fixed base 14, which is fixedly connected to the back of the transformer box 1. A limit rod 15 is slidably provided on the fixed base 14, and the limit rod 15 passes through the fixed base 14. A second positioning hole 13 is provided on the side of the positioning ring 7 away from the mounting cylinder 5. The second positioning hole 13 is slidably connected to the limit rod 15. A floating plate 16 is provided on the side of the fixed base 14 away from the positioning ring 7. The floating plate 16 is fixedly connected to the limit rod 15. A spring 18 is fixedly connected between the floating plate 16 and the fixed base 14.

[0033] When the limiting position on the mounting cylinder 5 is released, the floating plate 16 is pulled downwards. The floating plate 16 causes the limiting rod 15 to move downwards, and the limiting rod 15 is pulled out from the second positioning hole 13 on the outside of the positioning ring 7, thus releasing the movement limit of the mounting cylinder 5. After the floating plate 16 is released, under the pull of the spring 18, the floating plate 16 will move upwards with the limiting rod 15, and the limiting rod 15 will slide into the second positioning hole 13, restricting the movement of the mounting cylinder 5.

[0034] To facilitate the removal of the limiting rod 15 from the second positioning hole 13 at the bottom of the positioning ring 7, in a preferred embodiment, a handle 17 is provided on the side of the floating plate 16 away from the fixed base 14, and the handle 17 is fixedly connected to the floating plate 16. To release the limiting rod 15 from the positioning ring 7, simply grasp the handle 17 and pull the floating plate 16 downwards.

[0035] To facilitate the replacement and maintenance of the filter screen 6, at least two locking blocks 19 are provided on the edge of the filter screen 6. The locking blocks 19 are fixedly connected to the filter screen 6 and slidably connected to the slots 21 opened inside the mounting cylinder 5. A fixing bolt 20 is threadedly connected to the upper end of the locking blocks 19, and the fixing bolt 20 is threadedly connected to the bolt hole opened inside the slot 21. When installing the filter screen 6, push the filter screen 6 into the mounting cylinder 5, and the locking blocks 19 on the edge of the filter screen 6 slide into the slots 21 opened inside the positioning ring 7. When the filter screen 6 is pushed to the deepest point, rotate the locking blocks 19 on the fixing bolt 20, and the locking blocks 19 will screw into the bolt hole opened inside the slot 21, thereby completing the fixing of the filter screen 6.

[0036] How this application works:

[0037] An exhaust fan is fixedly installed inside the air intake window 4. The exhaust fan draws outside air into the transformer compartment 1 through the air intake window 4 to ensure normal heat dissipation of the electrical components inside the transformer compartment 1. The air enters the air intake window 4 through the mounting cylinder 5. The filter screen 6 inside the mounting cylinder 5 filters the dust in the airflow. The movable plate 8 can be rotated to quickly replace the filter screen 6 when it is full of dust, without the need for disassembly and reassembly, which is convenient for daily maintenance. When the mounting cylinder 5 at the top of the movable plate 8 rotates to the outside of the air intake window 4, the positioning device will limit the mounting cylinder 5 at the top of the movable plate 8, restricting the movable plate 8 from further rotation and ensuring stable airflow in and out of the mounting cylinder 5.
