Description

Technical Field

[0001] The present invention relates to the technical field of box-type substations, and in particular to a ventilation structure for box-type substations and the box-type substations. Background Art

[0002] Box-type substation, also called prefabricated substation or prefabricated substation; is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It organically combines transformer step-down, low-voltage distribution and other functions, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substations; A box-type substation generates a lot of heat when in use. If the heat accumulates inside the box and is not discharged, the internal temperature of the box will be high. In addition to affecting the service life of the internal electrical equipment, there are also great safety hazards. Therefore, the box-type substation is generally equipped with an exhaust window for heat dissipation. For example, the existing public document CN104332855B-Box-type substation discloses this type of substation. However, although this type of substation can achieve the heat dissipation effect during operation, due to the design of the exhaust window, the external rainwater will enter the box in rainy weather, which will damage the electrical equipment in the box and affect its service life. In addition, the existing box-type substations are generally fixed as a whole, which is very inconvenient for the transportation of the box-type substations before use. For example, the existing public document CN116706744B-A ventilation structure for a box-type substation and a box-type substation discloses a substation with such a defect; of course, there are also some assembled substations in actual use, but such substations need to be equipped with a lifting device for auxiliary installation, which is complicated to operate and labor-intensive; Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0032] Reference Figure 1 , Figure 2 and Figure 3 , which is the first embodiment of the present invention, and this embodiment provides a ventilation structure for a box-type substation. The ventilation structure can achieve different modes of heat dissipation inside the outer protective box 100 by adjusting the ventilation mechanism 200 according to the specific outdoor environment (sunny weather, cloudy day with high humidity, and rainy day). While ensuring heat dissipation and cooling, it can prevent excessive water in the air from entering the outer protective box 100 and causing damage to electrical equipment.

[0033] Specifically, it includes an outer protective box 100, including a front side panel, a rear side panel 101, side protective panels 102 symmetrically arranged on both sides in front of the rear side panel 101, a top side panel 103 arranged on the front side above the rear side panel 101, and a bottom side panel 104 arranged on the front side below the rear side panel 101, a box door is hinged on the front side panel to facilitate the staff to operate the inside of the outer protective box 100; and a ventilation mechanism 200, including a circulation cavity 201 and a heat dissipation component 202.

[0034] See Figure 3 and Figure 5 As shown, a plurality of second guide grooves 201b with openings at both ends are arranged in an array along the vertical direction inside the rear side plate 101, and the vertical cross-section of the second guide grooves 201b is arranged obliquely, and the interiors of the two side guard plates 102 are respectively arranged in an array along the vertical direction with the same number of first guide grooves 201a and third guide grooves 201c as the second guide grooves 201b, and the vertical cross-sections of the first guide grooves 201a and the third guide grooves 201c are arranged obliquely, and the first guide grooves 201a, the second guide grooves 201b and the third guide grooves 201c are arranged in a one-to-one correspondence ... The inclined upper end of the guide groove 201a is connected to the inclined lower end of the second guide groove 201b, and the inclined lower end of the third guide groove 201c is connected to the inclined upper end of the second guide groove 201b. The first guide groove 201a, the second guide groove 201b and the third guide groove 201c connected to each other form a flow chamber 201, so that the flow chamber 201 can be inclined as a whole. After the rainwater enters the third guide groove 201c, it is guided by the second guide groove 201b under the action of gravity and finally discharged from the first guide groove 201a. The inclined upper end of the third guide groove 201c is connected to the head end groove 201c-1, and the upper end of the head end groove 201c-1 penetrates the top surface of the side guard plate 102 to collect rainwater. The inclined lower ends of the plurality of first guide grooves 201a are connected to the same end groove 201a-2 arranged in the vertical direction to collect rainwater, and the lower end of the end groove 201a-2 is provided with a water outlet groove 201a-1 connected to the outside of the outer protective box 100 to discharge rainwater. When the above arrangement is in use, in rainy weather, external rainwater enters the circulation cavity 201 through the head end groove 201c-1, is guided by the circulation cavity 201, and is collected at the end groove 201a-2, and is finally discharged from the outlet groove 201a-1. The continuous circulation of rainwater in the circulation cavity can realize heat exchange inside the outer protective box 100, thereby preventing rainwater from entering the interior of the outer protective box 100 and effectively dissipating heat.

[0035] See Figure 3 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the heat dissipation component 202 is arranged inside the outer protective box 100 at the position of the head end slot 201c-1, and the heat dissipation component 202 includes a wind collecting box 202a, a T-shaped column 202b, an electromagnetic plate 202c, a first air pipe 202e and a second air pipe 202f. A plurality of first air pipes 202e forming a group are arranged in an array along the vertical direction on a side surface of the wind collecting box 202a close to the side guard plate 102, and a plurality of groups of first air pipes 202e are arranged in an array along the horizontal direction of the wind collecting box 202a. The wind collecting box 202a close to the side guard plate 102 A plurality of second air pipes 202f are arranged in a vertical array on one side surface, and a plurality of second air pipes 202f are arranged in a horizontal array along the wind collecting box 202a. The plurality of first air pipes 202e and the plurality of second air pipes 202f are arranged in a staggered manner. A first through groove 102c for the clearance fit of the first air pipe 202e is provided on the side guard plate 102 between adjacent head end grooves 201c-1, and a first through groove 102c for the free end of the second air pipe 202f to extend to the inside of the head end groove 201c-1 is provided on the inner wall of the side guard plate 102. The second through groove 102d of the first air pipe 202e is provided with air holes 202e-1 evenly distributed on the side wall of the free end of the first air pipe 202e. The second air pipe 202f is provided in a Z shape with the free end extending downward. The special Z-shaped design of the second air pipe 202f can realize air conduction into the flow cavity 201 on the one hand, and can prevent rainwater in the flow cavity 201 from flowing back into the air collecting box 202a on the other hand. The left and right sides of the air collecting box 202a are symmetrically fixed with mounting plates 202a-2, and an electromagnetic The electromagnetic plate 202c is fixedly connected to the side guard plate 102 through an L-shaped plate 202c-1, and the mounting plates 202a-2 on both sides of the electromagnetic plate 202c are symmetrically slidably sleeved with T-shaped columns 202b, and the setting of the T-shaped columns 202b can play a role in limiting and guiding the movement of the mounting plate 202a-2, and the T-shaped columns 202b on the side of the mounting plate 202a-2 away from the side guard plate 102 are slidably sleeved with springs 202b-1, and the setting of the springs 202b-1 can realize the reset of the mounting plate 202a-2; A circular groove 202a-1 is provided on one side of the air collecting box 202a away from the side guard plate 102, and a fan 202d is provided in the circular groove 202a-1. The driving motor of the fan 202d is fixedly installed on the outer side wall of the air collecting box 202a. The fan 202d can be conveniently provided to draw air into the air collecting box 202a. When the above arrangement is in use, the air inside the outer protective box 100 is guided into the wind collecting box 202a through the operation of the fan 202d, and is finally discharged through the air hole 202e-1 on the first air pipe 202e to achieve timely heat dissipation; when the outside is in a state of high humidity, the electromagnetic plate 202c is energized to magnetically adsorb the mounting plate 202a-2. Under this action, the first air pipe 202e is retracted into the first through groove 102c, and the second air pipe 202f loses the contact with the inner wall of the head end groove 201c-1. At this time, the air driven by the fan 202d enters the circulation cavity 201 and is discharged through the circulation cavity 201, thereby preventing the external humid air from entering the outer protective box 100 through the air hole 202e-1.

[0036] Furthermore, a blocking plate 202e-2 is fixedly provided on the free end of the first air pipe 202e extending to the outside of the outer protective box 100. When the first air pipe 202e contracts, the blocking plate 202e-2 blocks the end of the first through groove 102c to prevent external air from entering the outer protective box 100 through the first through groove 102c; a blocking ring 202f-1 is fixedly sleeved on the outer wall of the upper horizontal part of the second air pipe 202f. The blocking ring 202f-1 can fit well on the inner wall of the head end groove 201c-1 when the second air pipe 202f is exhausted, to prevent external air and rainwater from entering the outer protective box 100 through the second through groove 102d. It should be noted that when heat exchange and heat dissipation are performed through the circulation cavity 201, the first air pipe 202e should be in a contracted state, and the blocking plate 202e-2 blocks the end of the first through groove 102c.

[0037] In addition, the interior of the outer protective box 100 is used for the installation of electrical components, including high-voltage switchgear, low-voltage switchgear, low-voltage compensation equipment, low-voltage outgoing line circuit, transformer, etc. For details, please refer to the existing public document CN105762692B-Box-type substation, which will not be described in detail here; At the same time, a temperature sensor and a controller are also arranged inside the outer protective box 100 (the controller is used to control various electrical components in the device, excluding electrical components such as power supply transformers), and a humidity sensor is arranged outside the outer protective box 100. Example 2

[0038] Reference Figure 2 and Figure 3, which is the second embodiment of the present invention, is based on the previous embodiment, except that this embodiment is proposed in order to better guide rainwater into the flow cavity 201 in rainy weather and improve the heat exchange effect.

[0039] Specifically, a ramp 103c is fixedly provided on the top surface of the top side plate 103, and a flow collecting groove 103a is provided on the top surface of the top side plate 103 outside the ramp 103c, and a water inlet groove 103a-1 is provided on the bottom surface of the flow collecting groove 103a directly above the head end groove 201c-1; When the above arrangement is in use, the arrangement of the ramp 103c can guide the collected rainwater to the collecting trough 103a, and the rainwater collected in the collecting trough 103a enters the head end trough 201c-1 through the collecting trough 103a.
