Description

Technical Field

[0001] The utility model belongs to the technical field of transformer boxes, and in particular relates to a Huabian transformer box. Background Art

[0002] Huabian transformer box separates the high voltage box and transformer box, which is small in size and occupies less area. It is suitable for places with small space, which is conducive to saving floor space and is often used in photovoltaic power plants. However, due to the compact structure inside the high voltage box, the heat dissipation effect is poor, and the transformer box is set separately. The transformer box is exposed to the sun and is prone to high temperature operation when exposed to direct sunlight.

[0003] Traditional Chinese transformer boxes rely on natural wind or adding fans to cool the box:

[0004] The first method uses natural wind. In hot weather when the sun is directly shining on the high-voltage box and transformer box, natural wind cannot effectively cool down the box. It may cause the temperature inside the box to be too high, affecting the normal operation of the electrical components in the box and damaging the service life of the electrical components.

[0005] The second method is to add a fan: when there is severe weather such as typhoons or heavy rains, rainwater is likely to enter the box through the fan. The fan and the electrical components in the box are exposed to rainwater, which is likely to cause more serious electrical accidents and cause serious consequences.

[0006] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a kind of Chinese transformer box.

[0007] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0031] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] like Figures 1 to 3 As shown, the Huabian transformer box in one embodiment of the utility model comprises a high-voltage box 1, a transformer box 2 and an air duct 3. A first vent 11 is provided on the upper panel of the high-voltage box 1, and a circular water blocking ring 12 is welded on the high-voltage box 1. The water blocking ring 12 matches the first vent 11, and the first vent 11 can be surrounded in the circular ring of the water blocking ring 12. A fan exhaust fan 13 is also provided in the water blocking ring 12, and the air in the high-voltage box 1 can be discharged from the inside of the high-voltage box 1 under the action of the fan exhaust fan 13.

[0033] The fixing plate 14 is provided with a first bolt hole 141 and a second vent 142, and the second vent 142 matches the water blocking ring 12. After the second vent 142 is penetrated by the water blocking ring 12, the fixing plate 14 is bonded to the high-pressure box 1. The height of the water blocking ring 12 is greater than the thickness of the fixing plate 14, so that when there is water on the high-pressure box 1 and the second vent 142, the water cannot enter the first vent 11 because of the obstruction of the water blocking ring 12.

[0034] The air duct 3 is a hollow pipe, and a connecting plate 34 is welded at one end of the air duct 3. Second bolt holes 342 are provided at the four corners of the connecting plate 34. The second bolt holes 342 match the first bolt holes 141 on the fixing plate 14. The connecting plate 34 is docked on the fixing plate 14, and the bolts 341 penetrate the second bolt holes 342 and are threadedly connected with the first bolt holes 141. The air duct 3 can be fixed on the fixing plate 14 by tightening the bolts 341. When the electrical components in the high-voltage box 1 are maintained, the exhaust fan 13 is maintained at the same time. When maintaining the exhaust fan 13, it is only necessary to unscrew the bolts 341 and take down the air duct 3 to maintain the exhaust fan 13. After the maintenance work is completed, the connecting plate 34 is reinstalled on the fixing plate 14 and the bolts 341 are tightened.

[0035] Preferably, the air duct 3 is made of elastic material, and the shape of the air duct 3 can be adjusted within a certain angle range.

[0036] like Figure 1 and Figure 4 As shown, one end of the air duct 3 is fixedly connected to the fixing plate 14 with the connecting plate 34 installed, and the opening of the end away from the connecting plate 34 is facing downward, so that even if there is severe weather such as strong wind accompanied by heavy rain, rainwater cannot enter the high-pressure box 1.

[0037] A first guide hole 31 and a second guide hole 32 are provided on a downwardly opening section of the air duct 3. The second guide hole 32 is opened in the lower half of the transformer box 2 and is closer to the oil storage tank 22 and the radiator 21. The first guide hole 31 is opened in the upper half of the air duct 3 corresponding to the second guide hole 32.

[0038] A windshield 33 is provided in the air duct 3. The windshield 33 is welded above the first air guide hole 31, and the number of the windshields 33 matches the first air guide hole 31. When the exhaust fan 13 rotates, the wind drawn out from the high-pressure box 1 is blocked by the windshield 33, so that the wind changes its flow direction and blows out from the second air guide hole 32 and the outlet direction of the air duct 3. The windshield 33 can be set to be inclined downward at 45 degrees, so that the wind guiding effect is better. In rainy weather, because of the obstruction of the windshield 33, the rain is directly blocked by the windshield 33 and falls into the downward opening of the air duct 3, and cannot enter the high-pressure box 1, which can guide the wind and play a better protective role.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, a cooling box 4 is provided below the first guide hole 31 and the second guide hole 32. The cooling box 4 is an annular storage box. The cooling box 4 and the air duct 3 are interference fit. The cooling box outer wall 41 on the cooling box 4 has a certain elasticity, and the cooling box 4 can be drawn out of the air duct 3. A storage space 42 is provided between the cooling box outer wall 41 and the cooling box inner wall 43. The storage space 42 is a space with an upper opening and a lower closed space, which can be used to store cooling medium.

[0040] A third vent 44 is provided inside the cooling box 4, and the third vent 44 is arranged concentrically with the air duct 3 to facilitate air outlet.

[0041] A transformer box 2 is welded on one side of the high-voltage box 1, and an oil storage tank 22 is clamped on the transformer box 2. The oil in the oil storage tank 22 can replenish the oil loss in the transformer box 2. Since the heat generated by the transformer box 2 during operation is much greater than that of the high-voltage box 1, a radiator 21 is welded on the side of the transformer box 2 away from the high-voltage box 1, and the radiator 21 can dissipate heat for the transformer box 2.

[0042] Specifically, when the exhaust fan 13 rotates, the hot air of the high-voltage box 1 can be extracted, and the hot air is discharged to the end of the air duct 3 away from the high-voltage box 1. When the extracted hot air passes through the wind shield 33, the direction is changed, and it cannot flow out from the first guide hole 31 in large quantities, so it flows to the third vent 44. Since the cooling box 4 is provided in the air duct 3, the blown hot air can rotate in the storage space 42, so that the temperature of the hot air is reduced, and the hot air with reduced temperature is blown to the second guide hole 32 and the third vent 44. The opening of the second guide hole 32 faces the transformer box 2 and the oil storage tank 22, so the hot air blown from the second guide hole 32 with reduced temperature can accelerate the air flow around the oil storage tank 22 and the transformer box 2, which is helpful for the heat dissipation of the transformer box 2 and the oil storage tank 22 themselves. The hot air with reduced temperature blown out from the third vent 44 is blown to the radiator 21, so that the air flow rate around the radiator 21 is accelerated, which can achieve a better heat dissipation effect.

[0043] When the sun shines directly on the transformer box 2 and the radiator 21, the temperature of the transformer box 2 and the radiator 21 will be higher than the normal working temperature, resulting in insufficient heat dissipation of the radiator 21. At this time, the cooling box 4 can be removed, water can be added to the storage space 42 of the cooling box 4, and then the cooling box 4 can be installed in the air duct 3. Water can also be added to the storage space 42 from the first guide hole 31, so that the storage space 42 does not need to be taken out, which is more convenient and quick.

[0044] The hot air extracted from the high-voltage box 1 is blown onto the water surface in the storage space 42, and the water absorbs the heat, turning the hot air into cool air. In this way, the cool air blows from the second guide hole 32 to the oil storage tank 22 and the transformer box 2, so that the temperature of the transformer box 2 and the oil storage tank 22 is reduced. The wind blown from the third vent 44 passes through multiple storage spaces 42, and the temperature of the wind continues to decrease. When the wind with reduced temperature is blown out from the third vent 44 and blows toward the radiator 21, the cooling effect is better.

[0045] At night, the outdoor temperature becomes lower. Since the first guide hole 31 is opened above the storage space 42, the heat emitted by the water in the storage space 42 can be discharged from the first guide hole 31. On rainy days, rainwater can flow into the storage space 42 from the first guide hole 31, which can reduce the frequency of replenishing water in the storage space 42 in summer.

[0046] Preferably, coolant can be added into the storage space 42, so that the cooling effect is better.

[0047] Since only the fan is provided on the high-voltage box 1, the number of fans is reduced, achieving a better heat dissipation effect while saving energy.

[0048] When in use, firstly, the first vent 11 is opened on the upper panel of the high-voltage box 1, and then the water blocking ring 12 is welded around the first vent 11, and the exhaust fan 13 is installed in the water blocking ring 12, and then the fixing plate 14 is matched with the water blocking ring 12, so that the bottom of the fixing plate 14 is fixed on the upper panel of the high-voltage box 1. Finally, the end of the air duct 3 connected with the connecting plate 34 is bolted to the fixing plate 14, and the fan and the air duct are installed. After the air duct is installed, adjust the end of the air duct 3 away from the connecting plate 34 so that its opening faces downward, continue to adjust the angle of the air duct so that the second guide hole 32 and the third vent 44 opened on the air duct 3 are respectively aligned with the oil storage tank 22 and the radiator 21, and finally the cooling box 4 is loaded into the air duct 3, and the fan exhaust fan 13 is started, so that the heat dissipation effect of the high-voltage box 1 and the transformer box 2 can be achieved. When the weather is hot in summer, water or other cooling media are added to the storage space 42 of the cooling box 4 to achieve a better heat dissipation effect. This can not only solve the heat dissipation problem of the high-voltage box 1 and the transformer box 2, but also solve the problem of water entering the fan after the fan is provided on the high-voltage box 1, and the use is safer.
