Description

Technical Field

[0001] The utility model belongs to the technical field of box-type transformer substations, in particular to a box-type transformer substation. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation, is a factory-prefabricated compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices. Box-type substations are usually composed of a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed and movable steel structure box and three parts inside: high-voltage switch room, transformer room and low-voltage distribution switch room.

[0003] This equipment is widely used in urban load-intensive areas, rural areas, residential areas, parks and other places, and is especially suitable for occasions with limited space or that require rapid deployment.

[0004] A box-type substation with a ventilation structure is provided in the Chinese patent announcement number CN220797593U. In this patent, rainwater will be sucked from the through hole on rainy days and then discharged through the water outlet, so that it can be used on rainy days and can effectively prevent rainwater from entering the equipment. When the equipment is not in use, the ventilation channel can be closed to prevent dust from entering, which has a dust-proof effect.

[0005] However, in actual use, the heat dissipation structure of the device is arranged in the ventilation box, and the ventilation box is hung outside the box. The size of the fan is severely limited by the size of the ventilation box. This greatly limits the power of the fan in the ventilation box, limiting its heat dissipation effect. At the same time, in hot weather, the box is exposed to the sun, and the temperature of the box will rise sharply. Heat dissipation only by the fan cannot meet the demand. Summary of the invention

[0006] The utility model aims to provide a box-type substation in view of the problems existing in the prior art.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a box-type substation, including a box body, a hollow raised seat installed at the bottom of the box body, a cooling fan embedded in the bottom wall of the box body to discharge the heat in the box body into the hollow raised seat, a grid plate arranged on the bottom wall of the box body through multiple pads to facilitate the heat to be discharged through the cooling fan, two air intake hoods symmetrically arranged on the front of the box body to provide flowing air to the cooling fan, a double door is provided on the front of the box body and between the two air intake hoods, the grid plate is provided with the core components of the substation, the left and right sides and the back of the box body are provided with side panel boxes, the top of the box body is provided with a top box, and the side panel box is connected to the top box through a connecting pipe.

[0008] The box is raised through a hollow lifting seat to prevent water on the ground from entering the box. External air enters the box through the air intake hood and is then discharged into the hollow lifting seat below through the cooling fan, which can effectively take away the heat in the box. The core components of the substation are separated from the cooling fan by grid plates to allow air to circulate better. By filling the side box and the top box with cold water, the box can be kept in a relatively low temperature environment even if it is exposed to high temperature and scorching sun for a long time, so that the core components of the substation can work in a good environment, thereby improving the service life of the core components of the substation.

[0009] Optionally, a placement groove is provided in the middle of the bottom wall of the box body and vertically penetrates the bottom wall of the box body and the top wall of the hollow lifting seat, the heat dissipation fan is embedded in the placement groove, and the side wall of the hollow lifting seat is provided with an air outlet.

[0010] The provided placement slot facilitates the installation of the cooling fan, and the air outlet is used to quickly discharge the hot air to the outside.

[0011] Optionally, the grid plate is a plastic steel grid plate, and the distance between the grid plate and the bottom wall of the box body is not less than 15 cm.

[0012] The plastic-steel grating not only has guaranteed strength but also provides insulation protection. The grating is used to separate the core components of the substation from the cooling fan, and the reserved space can increase air flow.

[0013] Optionally, a notch adapted to the air intake hood is provided on the front of the box body, an air inlet with a diameter smaller than the side length of the bottom surface of the air intake hood is provided at the bottom of the air intake hood, and a filter plate is bonded to the air inlet.

[0014] The air inlet of the air intake hood faces downward, which can effectively prevent rain. The filter plate can not only block birds from entering the box, but also filter the incoming air to a certain extent.

[0015] Optionally, a door groove adapted to the double door is provided on the front of the box body, and the door groove includes an inlet and outlet penetrating the front wall of the box body, and a door panel groove with a depth of half the thickness of the front wall of the box body and the same axis as the inlet and outlet, the width and height of the door panel groove are both greater than the width and height of the inlet and outlet, and the thickness of the double door is adapted to the depth of the door panel groove.

[0016] Door panel grooves are set to leave space for the double-opening door, and the diameter difference between the inlet and outlet and the door panel grooves can effectively provide an interception effect for the double-opening door, which can not only prevent the double-opening door from turning inwards, but also have a certain rain blocking effect.

[0017] Optionally, the door groove also includes a middle plate with one end slidingly sleeved on the groove wall at the lower edge of the inlet and outlet and the other end contacting the inner top wall of the inlet and outlet. The front inner wall of the lower edge of the inlet and outlet is provided with an embedding groove adapted to the middle plate, and the front side of the middle plate is flush with the front inner wall of the door panel groove.

[0018] The function of the middle plate is to block the middle gap of the double doors after they are closed, preventing rainwater from entering the box through the gap. When the staff maintain the core components of the substation, the middle plate can also be slid to the side without hindering the staff from entering and exiting.

[0019] Optionally, the door groove further includes a plurality of drainage chute evenly arranged on the bottom wall of the door panel groove, and the side cross-section of the drainage chute is triangular.

[0020] The drainage chute provided can quickly drain away the rainwater that penetrates into the door panel groove.

[0021] Optionally, the joints of two adjacent side panel boxes are connected, the height of the side panel boxes is level with the height of the box body, the outer sides of the side panel boxes and the top box are provided with sun-proof and heat-insulating coatings, an overflow pipe is provided at the top of the top box, and a water inlet pipe is provided at the lower end of the side wall of one of the side panel boxes, and the height of the end of the overflow pipe away from the top box is level with the water inlet pipe.

[0022] When the box is put into use, water is poured into the side panel box through the water inlet pipe until the water overflows from the overflow pipe on the top of the top box. The water in the side panel box and the top box provides a good heat insulation and heat absorption medium for the box, which can not only resist external heat sources but also absorb part of the heat in the box, creating a good working environment for the core components of the substation. At the same time, the sun-proof and heat-insulating coating can also reduce the tendency of the side panel box and the top box to be heated by sunlight.

[0023] Compared with the prior art, the beneficial effects of the utility model are as follows: first, the box body is raised by the hollow lifting seat to prevent water on the ground from entering the box body, and the heat dissipation fan is arranged on the bottom wall of the box body. When the heat dissipation fan is running, the external air enters the box body through the air intake hood, and then is discharged into the hollow lifting seat below through the heat dissipation fan, which can effectively take away the heat in the box body and prevent the entry of rainwater. In addition, the core components of the substation are separated from the heat dissipation fan by the grid plate, which not only further raises the position of the core components of the substation to achieve the waterproof effect, but also allows air to circulate better to maximize the heat dissipation effect. Finally, by arranging side panel boxes on the left, right and rear sides of the box body and arranging a top box on the top of the box body, a good sun-proof and heat-insulating space can be provided for the box body by filling the side panel boxes and the top box with cold water, so that even if the box body is exposed to the high temperature sun for a long time, it can ensure that the box body is in a relatively low temperature environment, so that the core components of the substation can work in a good environment, delay the aging rate of components, and improve the service life of the core components of the substation.

When the cooling fan 3 is running, the external air enters the box body 1 through the air intake hood 5, and then is discharged into the hollow lifting seat 2 below through the cooling fan 3, which can effectively take away the heat in the box body 1 and prevent rainwater from entering.

[0033] In addition, the substation core component 8 is separated from the heat dissipation fan 3 by the grid plate 4, which not only further raises the position of the substation core component 8 to achieve a waterproof effect, but also allows air to circulate better, thereby maximizing the heat dissipation effect.

[0034] Finally, by arranging side panel boxes 9 on the left, right and rear sides of the box body 1 and arranging a top box 10 on the top of the box body 1, a good sun-proof and heat-insulating space can be provided for the box body 1 by filling the side panel boxes 9 and the top box 10 with cold water, so that even if the box body 1 is exposed to the high temperature and scorching sun for a long time, the box body 1 can be kept in a relatively low temperature environment, so that the core components 8 of the substation can work in a good environment, the aging speed of the components is delayed, and the service life of the core components 8 of the substation is improved.

[0035] A placement groove is provided in the middle of the bottom wall of the box body 1 and vertically penetrates the bottom wall of the box body 1 and the top wall of the hollow raised seat 2 .

[0038] The plastic steel grid plate not only has guaranteed strength but also plays an insulating and protective role. The grid plate 4 is used to separate the core component 8 of the substation and the cooling fan 3, and the reserved space can increase the air flow.

[0039] See also Figure 4 It should be noted here that a through hole for wiring is also opened at the bottom of the box body 1, and a corresponding notch is opened on the side wall of the hollow lifting seat 2. The external cable enters from the notch reserved in the side wall of the hollow lifting seat 2, and then enters the box body 1 through the through hole and passes through the grid plate 4 to connect with the core component 8 of the substation.

[0040] A notch matched with the air inlet hood 5 is provided on the front of the box body 1, and an air inlet with a diameter smaller than the side length of the bottom surface of the air inlet hood 5 is provided at the bottom of the air inlet hood 5, and a filter plate is bonded to the air inlet.

[0041] Here, the design of the air inlet of the air intake cover 5 facing downward can effectively prevent rain, and the filter plate can not only block flying birds from entering the box body 1, but also filter the incoming air to a certain extent.

[0042] See also Figure 2-3 A door groove 6 adapted to the double-opening door 7 is opened on the front of the box body 1. The door groove 6 includes an inlet and outlet 61 that penetrates the front wall of the box body 1, and a door plate groove 62 with a depth of half the thickness of the front wall of the box body 1 and the same axis as the inlet and outlet 61. The width and height of the door plate groove 62 are both greater than the width and height of the inlet and outlet 61, and the thickness of the double-opening door 7 is adapted to the depth of the door plate groove 62.

[0043] The door panel groove 62 is provided to leave space for the double door 7, and the diameter difference between the inlet and outlet 61 and the door panel groove 62 can effectively provide an interception effect for the double door 7, which can not only prevent the double door 7 from turning inwards, but also have a certain rain blocking effect.

[0044] Among them, the door groove 6 also includes a middle plate 63 whose one end is slidably sleeved on the groove wall at the bottom edge of the inlet and outlet 61 and the other end is in contact with the inner top wall of the inlet and outlet 61. An embedding groove 611 adapted to the middle plate 63 is opened on the front inner wall of the bottom edge of the inlet and outlet 61, and the front side of the middle plate 63 is flush with the front inner wall of the door plate groove 62.

[0045] The function of the middle plate 63 is to block the middle seam of the double door 7 after the double door 7 is closed to prevent rainwater from entering the box body 1 through the middle seam. When the staff maintains the core components 8 of the substation, the middle plate 63 can also be slid to the side without hindering the staff from entering and exiting.

[0046] Secondly, the door groove 6 also includes a plurality of drainage chute 64 evenly arranged on the inner bottom wall of the door plate groove 62, and the side cross section of the drainage chute 64 is triangular.

[0048] When the box body 1 is put into use, water is injected into the side panel box 9 through the water inlet pipe 12 until the water overflows from the overflow pipe 11 on the top of the top box 10. The water in the side panel box 9 and the top box 10 provides a good heat insulation and heat absorption medium for the box body 1, which can not only resist external heat sources but also absorb part of the heat in the box body 1, creating a good working environment for the core components 8 of the substation. At the same time, the sun-proof and heat-insulating coating can also reduce the tendency of the side panel box 9 and the top box 10 to be heated by sunlight.

[0049] In actual operation, a valve can be installed on the water inlet pipe 12, and the valve can be closed when water injection is no longer needed. If the actual situation permits, the water inlet pipe 12 and the overflow pipe 11 are connected to the nearest river or tap water official website, and the water pump continuously injects water into the side box 9 and the top box 10 to make the water in the side box 9 and the top box 10 flow, so as to form a better heat absorption and water insulation space in the side box 9 and the top box 10, and further improve the heat dissipation effect of the box body 1.
