Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformers, in particular to a corrugated top heat dissipation structure for box-type transformers. Background Art

[0002] Box-type transformer, usually referred to as "box transformer", is a kind of power equipment that integrates traditional transformers into a box-type shell. Box-type transformer plays an important role in power transmission and distribution systems with its unique structure and functional advantages.

[0003] However, the traditional box-type transformer top cover is a fully enclosed top cover. When the transformer room and the high and low voltage rooms inside the box-type transformer are in operation, a large amount of heat will be generated. The heat will float upwards and can only be dissipated by conduction and radiation, with a poor heat dissipation effect. For example, when the box-type transformer is working, a large amount of heat will be generated in the transformer room, high voltage room and low voltage room inside the box-type transformer when it is in operation. The heat will dissipate (float) upwards and the heat will be dissipated by conduction, convection and radiation. The box-type transformer with a traditional fully enclosed top cover can only dissipate heat by conduction and radiation, just like the fully enclosed steel and cement rooms, with a poor heat dissipation effect. Utility Model Content

[0004] The utility model discloses a corrugated top heat dissipation structure for a box-type transformer, which aims to solve the technical problem that the top cover of a traditional box-type transformer is a fully enclosed top cover, and a large amount of heat is generated when the transformer chamber and the high and low voltage chambers in the box-type transformer are in operation. The heat floats up, and the heat dissipation effect is poor only by conduction and radiation.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A corrugated top heat dissipation structure for a box-type transformer includes a box-type transformer body, wherein the box-type transformer body is composed of a base, a high-voltage chamber, a transformer chamber, a low-voltage chamber, and a corrugated top body, and further includes:

[0007] Guiding mechanism: the guiding mechanism is arranged on the base;

[0008] The corrugated roof body is located at the top of the high-voltage chamber, the transformer chamber and the low-voltage chamber. The corrugated roof body is composed of a number of stacked tiles, and convection holes are formed between the tiles. The corrugated roof body is used in conjunction with the box-type transformer body.

[0009] In this solution, the box-type transformer top cover adopts a corrugated top structure. In addition to heat dissipation through conduction and radiation, it can also rely on the convection holes of the corrugated roof for convection heat dissipation. It has good heat dissipation effect, saves materials and is environmentally friendly. After heat dissipation, the temperature inside the box-type transformer body is reduced, which can effectively ensure the life of the box-type transformer body and ensure that the temperature rise is within the range specified by national standards.

[0010] In a preferred embodiment, the guiding mechanism includes three mounting grooves opened on the outer wall of the top of the base, two connecting shafts are provided on the bottom inner wall of the mounting groove, exhaust fans are provided at the top of the two connecting shafts, and diversion partitions distributed at equal distances are provided on the inner wall of the mounting groove near the top.

[0011] By adopting the above technical solution, the guiding mechanism can guide the air inside the box-type transformer body to circulate, and the hot air gathered inside the box-type transformer body can be rotated by the exhaust fan in the installation groove. Under the action of the diversion partition, the blown wind is dispersed and floated upward, so that the internal hot air is evenly blown onto the corrugated top body. In conjunction with the convection holes on the corrugated top body, the internal air circulation is smoother, and the mutual cooperation achieves a better heat dissipation effect.

[0012] As can be seen from the above, a corrugated top heat dissipation structure for a box-type transformer includes a box-type transformer body, wherein the box-type transformer body is composed of a base, a high-voltage chamber, a transformer chamber, a low-voltage chamber and a corrugated top body, and further includes:

[0013] Guiding mechanism: the guiding mechanism is arranged on the base;

[0014] The corrugated roof body is located at the top of the high-voltage chamber, the transformer chamber, and the low-voltage chamber. The corrugated roof body is composed of a plurality of stacked tiles, with convection holes formed between the tiles. The corrugated roof body is used in conjunction with the box-type transformer body. The corrugated roof heat dissipation structure for a box-type transformer provided by the utility model utilizes the convection holes on the corrugated roof body for convection heat dissipation. In conjunction with the guide fan and the diversion partition to divert and evacuate the gas, the hot air inside the box-type transformer body is evenly blown out, achieving good heat dissipation effect, saving materials and being environmentally friendly, and effectively ensuring the life of the box-type transformer body.

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0021] The utility model discloses a corrugated top heat dissipation structure for a box-type transformer, which is mainly used in scenarios where the traditional box-type transformer top cover is a fully enclosed top cover. A large amount of heat is generated during operation of the transformer chamber and the high and low voltage chambers in the box-type transformer. The heat rises and the heat dissipation effect is poor if it is only dissipated by conduction and radiation.

[0022] Reference Figure 1 and Figure 2 A corrugated top heat dissipation structure for a box-type transformer includes a box-type transformer body, which is composed of a base 1, a high-voltage chamber 2, a transformer chamber 3, a low-voltage chamber 4, and a corrugated top body 5, and further includes:

[0023] Guiding mechanism: The guiding mechanism is provided on the base 1;

[0024] The corrugated roof body 5 is located at the top of the high-voltage chamber 2, the transformer chamber 3 and the low-voltage chamber 4. The corrugated roof body 5 is composed of a number of stacked tiles 6, and convection holes are formed between the tiles 6. The corrugated roof body 5 is used in conjunction with the box-type transformer body.

[0025] In the specific working process, the box-type transformer body is composed of the base 1, the high-voltage chamber 2, the low-voltage chamber 4, the transformer chamber 3 and the corrugated top body 5. The high-voltage chamber 2, the transformer chamber 3 and the low-voltage chamber 4 are distributed on the base 1 from left to right. The box-type transformer top cover with the corrugated top body 5 structure has not only the two heat dissipation effects of conduction and radiation, but also relies on the convection holes of the corrugated for convection heat dissipation, effectively ensuring the service life of the box-type transformer body and ensuring that the temperature rise is within the range specified by the national standard.

[0026] It should be noted that: According to relevant research, for every 1 degree increase in temperature of the box-type transformer body, the life of the box-type transformer is shortened by 8 years. The use of this patented technology can effectively ensure the life of the box-type transformer body.

[0027] Among them, several tiles 6 are stacked at an angle, so that multiple tiles 6 are stacked at an angle to form a corrugated top body 5. When rainwater drops from the top, it can flow down through the inclined tiles 6 without flowing back or gathering on the tiles 6. The special design of the corrugated top body 5 allows gaps to exist between the multiple tiles 6, forming convection holes to achieve a heat dissipation effect.

[0028] Reference Figure 1 and Figure 2 In a preferred embodiment, a first handle 7 is fixedly connected to one side outer wall of the transformer chamber 3, a side door 8 is provided on one side outer wall of the high-voltage chamber 2, and a second handle 9 is fixedly connected to one side outer wall of the side door 8.

[0029] Specifically, the transformer chamber 3 can be opened through the first handle 7, and the high-voltage chamber 2 can be opened through the second handle 9 on the side door 8 on the side of the high-voltage chamber 2. The low-voltage chamber 4 is also provided with a side door and handle, so that the condition of the internal components can be observed and then inspection and maintenance can be carried out.

[0030] Reference Figure 3 and Figure 4 In a preferred embodiment, the guiding mechanism includes three mounting grooves 10 opened on the top outer wall of the base 1, two connecting shafts 12 are provided on the bottom inner wall of the mounting groove 10, and exhaust fans 13 are provided at the top of the two connecting shafts 12. The inner wall of the mounting groove 10 near the top is provided with diversion partitions 11 distributed at equal distances.

[0031] Specifically, six exhaust fans 13 are located in the base 1. By rotating two exhaust fans 13 in the three mounting slots 10, the wind blown out is dispersed and floats upward under the action of the diverter baffle 11, so that the hot air gathered inside the box-type transformer is evenly blown onto the corrugated top body 5. In conjunction with the convection holes on the corrugated top body 5, the internal air circulation is smoother.

[0032] It should be noted that a low-power motor (not shown in the figure) is connected to one end of the connecting shaft 12 to drive the exhaust fan 13 to rotate. The exhaust fan 13 is inside the base 1 and does not affect the operation of the components inside the box-type transformer while dissipating heat.

[0033] Among them, the diverter baffle 11 is set to an "inverted eight" structure. In this way, the diverter baffle 11 with the "inverted eight" structure conducts the wind fanned out by the exhaust fan 13, so that the straight-line conducted wind can be dispersed to the interior of the box-type transformer body, and hot air is evenly blown out to every corner of the interior, which cooperates with the corrugated top body 5 to achieve a good heat dissipation effect.

[0034] Among them, the exhaust fan 13, the diverter baffle 11 and the corrugated top body 5 are used in combination. In this way, the airflow formed by the rotation of the exhaust fan 13 is diverted and evacuated by the diverter baffle 11, and the hot air inside the box-type transformer body is evenly blown to the corrugated top body 5. With the diversion of the corrugated top body 5, the hot air is blown out evenly to achieve the heat dissipation effect.

[0035] Working principle: When in use, the box-type transformer body consists of a base 1, a high-voltage chamber 2, a low-voltage chamber 4, a transformer chamber 3 and a corrugated top body 5. The box-type transformer body will generate heat inside when working. The corrugated top body 5 can dissipate heat by conduction and radiation, and can also dissipate heat by convection through the convection holes of the corrugated. At the same time, the six exhaust fans 13 can rotate. Under the action of the diverter baffle 11, the blown wind is dispersed and floated upward, so that the hot air gathered inside the box-type transformer body is evenly blown onto the corrugated top body 5. Combined with the convection holes on the corrugated top body 5, the internal air circulation is smoother and the heat dissipation effect is better, thereby effectively ensuring the life of the box-type transformer body.

[0036] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
