Description

Technical Field

[0001] The invention relates to the technical field of outdoor terminal boxes for transformer substations, in particular to a dustproof and heat dissipation structure of an outdoor terminal box for transformer substations. Background Art

[0002] For the terminal box installed outdoors in the substation, due to the hot and humid weather in summer, the temperature difference between the inside of the terminal box and the environment is large, and the uneven heat dissipation of the terminal box can easily cause internal metal corrosion, poor connection of the secondary terminals, heating and sparking. In the existing technology, heat dissipation is mostly achieved by opening heat dissipation ports. This method has a poor heat dissipation effect. Using this method to dissipate heat can easily cause dust accumulation on the wires in the terminal box, which is more detrimental to heat dissipation, and can affect the use of the terminal box and shorten its service life.

[0003] The existing publication number CN205693204U discloses an intelligent heat dissipation device for a substation terminal box, which includes a terminal box body, a temperature and humidity sensor provided on the internal top plate of the terminal box body, an exhaust fan provided on the upper part of the two side plates of the terminal box body, exhaust ducts connected to the corresponding parts of the two side plates of the terminal box body and the exhaust fans by bolts, the lower end of the terminal box body is connected to the base, the front panel and the rear panel of the base are symmetrically provided with ventilation windows, C-shaped rails are symmetrically provided on the upper and lower plate surfaces of the base along the length direction, a dustproof net is provided between the C-shaped rails, a handle is provided at one end of the dustproof net, and the upper plate between the C-shaped rails in the base is provided with a threading hole and a vent hole that passes through the terminal box body. It has the advantages of simple structure, good heat dissipation effect, easy installation, rain and dustproof, and automatic heat dissipation and dehumidification according to temperature and humidity conditions.

[0004] In the current design of the heat dissipation structure of the substation terminal box, a method combined with ventilation is usually adopted to ensure that the interior of the terminal box can be effectively ventilated and dissipated. In the above-mentioned technical solution of the intelligent heat dissipation device of the substation terminal box, the designer sets a dustproof net and designs a structure of interconnected holes to ensure air circulation while achieving the purpose of heat dissipation. However, in order to ensure that the air circulation is not obstructed, the dustproof net is designed to be a porous structure. This porous structure, together with the design of other ventilation holes, ensures the heat dissipation effect inside the box, but also brings problems. Due to the existence of these holes, fine dust particles can enter the interior of the equipment with the flow of air. Therefore, although the heat dissipation function of the terminal box is realized, its comprehensive performance of dust prevention and heat dissipation is not optimally utilized.

[0005] Therefore, those skilled in the art provide a dustproof and heat dissipation structure for an outdoor terminal box of a substation to solve the problems raised in the above background technology. Summary of the Invention

[0006] The object of the present invention is to provide a dustproof and heat dissipation structure for a transformer substation outdoor terminal box, so as to solve the problem in the above background art that the comprehensive performance of dustproof and heat dissipation of the existing transformer substation outdoor terminal box is not optimally exerted.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A dustproof and heat-dissipating structure for an outdoor terminal box in a substation comprises: a terminal box body, a heat-dissipating window installed on the side of the terminal box body, a heat-dissipating fan embedded in the top of the terminal box body, and a ventilation window provided below the heat-dissipating fan, a protective cover installed on the top outer side of the heat-dissipating fan, a mounting seat ring provided on the bottom outer edge of the heat-dissipating fan, and a flange ring fixedly provided along the top edge of the ventilation window, a ventilation pipe installed in the middle of the interior of the ventilation window, and a curved groove connected to the outer side of the lower end of the ventilation pipe, a holder fixedly installed in the interior of the curved groove, and a filter screen for dust filtering embedded in the interior of the holder, an air outlet provided on the end of the curved groove away from the ventilation pipe, and the curved groove is communicated with the interior of the terminal box body through the air outlet.

[0009] As a further solution of the present invention: the ventilation window penetrates from the top of the terminal box body to the inner top of the terminal box body, and a bucket mouth pipe is provided at the bottom of the heat dissipation fan.

[0010] As a further solution of the present invention: the mounting seat ring is fixedly connected to the heat dissipation fan, and the inner wall of the mounting seat ring is a threaded structure.

[0011] As a further solution of the present invention: a threaded connection is formed between the mounting seat ring and the outer wall of the flange ring, and the heat dissipation fan is connected to the ventilation window through the threaded connection structure between the mounting seat ring and the flange ring.

[0012] As a further solution of the present invention: the outer structural shape of the curved groove is a curved structure, and the curved groove is distributed in a cross shape with respect to the symmetric center line of the ventilation pipe.

[0013] As a further solution of the present invention: the inlet end of the curved groove is connected to the lower end of the ventilation pipe, and the curved groove is connected to the heat dissipation fan through the ventilation pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A heat dissipation fan is embedded and installed on the top of the terminal box body, and a mounting seat ring is integrated on the outer edge of the bottom of the heat dissipation fan. A ventilation window is provided under the heat dissipation fan, and the ventilation window passes through the top of the terminal box body and is installed on the top of the inner wall of the terminal box. The wind from the heat dissipation fan enters the interior of the ventilation window through the ventilation pipe. The lower end of the ventilation pipe is a hollow structure, and the air will enter the curved groove from the ventilation pipe. The curved groove is used to flow and transport the air. The curved structure of the curved groove can effectively prevent dust from directly entering the interior of the terminal box body. In this way, when the interior of the terminal box body is cooled, the entry of dust is indirectly intercepted. By using multiple sets of curved grooves with curved structures, the conveying path is extended and the conveying path is complicated. At the same time, a filter is embedded and installed inside the curved groove. The filter will cooperate with the curved groove to filter and intercept the dust carried by the air, thereby further improving the comprehensive performance of dust prevention and heat dissipation.

[0016] 2. There is a threaded connection between the mounting seat ring and the flange ring, and the threaded connection is used to connect the heat dissipation fan to the top of the ventilation window. This makes it easy to disassemble the heat dissipation fan. After removing the heat dissipation fan from the top of the ventilation window, the inside of the ventilation window is exposed. The filter can be pulled out for cleaning and replacement by using the interlocking structure between the card seat and the filter. While achieving dust-proof heat dissipation, it also avoids internal blockage, further improving the comprehensive performance of dust-proof heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 5 , an embodiment of the present invention provides a dust-proof and heat-dissipating structure of an outdoor terminal box in a substation, comprising: a terminal box body 1, a heat dissipation window 2 installed on the side of the terminal box body 1, a heat dissipation fan 3 embedded and installed on the top of the terminal box body 1, and a ventilation window 6 provided below the heat dissipation fan 3, a protective cover 4 installed on the top outer side of the heat dissipation fan 3, a mounting seat ring 5 provided on the bottom outer edge of the heat dissipation fan 3, and a flange ring 7 fixedly provided on the top edge of the ventilation window 6, the ventilation window 6 penetrates from the top of the terminal box body 1 to the inner top of the terminal box body 1, a bucket mouth pipe 13 is provided at the bottom of the heat dissipation fan 3, the mounting seat ring 5 and the heat dissipation fan 3 are fixedly connected, and the inner wall of the mounting seat ring 5 is a threaded structure, the mounting seat ring 5 and the outer wall of the flange ring 7 are threadedly connected, and the heat dissipation fan 3 is connected to the ventilation window 6 through the threaded connection structure between the mounting seat ring 5 and the flange ring 7;

[0025] Specifically, a mounting seat ring 5 is integrally provided on the bottom edge of the heat dissipation fan 3, and a threaded connection is formed between the mounting seat ring 5 and the flange ring 7 provided on the top of the ventilation window 6, thereby realizing the stable installation of the heat dissipation fan 3 at the top position of the ventilation window 6. This threaded connection method not only ensures the reliability of the installation, but also provides great convenience, because it allows the user to easily disassemble the heat dissipation fan 3 to facilitate the necessary inspection and cleaning work inside the ventilation window 6. The ventilation window 6 is designed to pass through the top of the terminal box body 1 and is installed at the inner top position of the terminal box body 1. This design ensures effective communication between the ventilation window 6 and the heat dissipation fan 3. Through this connection, the heat dissipation fan 3 can effectively blow air to dissipate heat inside the terminal box body 1, ensuring that the equipment operates under suitable temperature conditions. The wind is discharged from the heat dissipation windows 2 on both sides of the terminal box body 1. This design not only improves the heat dissipation efficiency, but also effectively prevents dust and other tiny particles from entering the interior of the terminal box through the double-layer mesh structure covering the inner wall of the heat dissipation window 2, thereby protecting the internal electronic components from contamination.

[0026] A ventilation pipe 8 is installed in the middle of the interior of the ventilation window 6, and a curved groove 9 is connected to the outer side of the lower end of the ventilation pipe 8. A card seat 11 is fixedly installed inside the curved groove 9, and a filter screen 12 for dust filtering is embedded in the card seat 11. An air outlet 10 is provided at one end of the curved groove 9 away from the ventilation pipe 8, and the curved groove 9 is communicated with the interior of the terminal box body 1 through the air outlet 10. The external structure of the curved groove 9 is a curved structure, and the curved groove 9 is distributed in a cross shape with respect to the symmetrical center line of the ventilation pipe 8. The inlet end of the curved groove 9 is communicated with the lower end of the ventilation pipe 8, and the curved groove 9 is communicated with the heat dissipation fan 3 through the ventilation pipe 8;

[0027] Specifically, the internal structure of the heat dissipation fan 3 is designed to be bucket-shaped, and the bucket mouth pipe 13 arranged at the bottom can be smoothly connected to the upper end of the ventilation pipe 8. This design ensures that the wind generated by the heat dissipation fan 3 can effectively enter the ventilation pipe 8 and flow along a specific path. The lower end of the ventilation window 6 and the inlet end of the curved groove 9 are also designed to be connected to each other, so that the wind can smoothly enter the interior of the curved groove 9 from the ventilation pipe 8. The structure of the curved groove 9 is a curved structure, which not only helps to extend the air flow path, but also through its complex conveying path design, while the air flows, it prevents dust from directly entering the interior of the terminal box body 1. A filter screen 12 is also embedded in the interior of the curved groove 9. The filter screen 12 can effectively intercept and filter dust and other tiny particles in the air. The air that has undergone such double treatment will eventually be discharged into the interior of the terminal box body 1 through the air outlet 10 arranged on the outer wall of the ventilation window 6, ensuring that the temperature inside the terminal box is maintained at an appropriate level, thereby protecting the stable operation of the internal electronic equipment.

[0028] The working principle of the present invention is:

[0029] When using the present invention, the cooling fan 3 starts working first, and the generated wind force is carried into the ventilation pipe 8 along the bucket mouth pipe 13 at the bottom of the cooling fan 3, and then enters the curved groove 9 through the ventilation pipe 8. When the air circulates inside the curved groove 9 of the curved structure, it will be filtered by the filter mesh 12, and the dust and tiny particles in the air are effectively intercepted. The clean air continues to flow along the path of the curved groove 9, and is finally discharged into the interior of the terminal box body 1 evenly through the air outlet 10. This process not only achieves effective heat dissipation inside the terminal box, but also ensures the cleanliness of the internal environment and prevents dust from contaminating electronic components. At the same time, the heat dissipation window 2 set on the side of the terminal box body 1 also plays a role in auxiliary heat dissipation. It allows hot air to be discharged from the inside of the terminal box, further improving the heat dissipation efficiency. In addition, the double-layer mesh structure covering the inner wall of the heat dissipation window 2 effectively blocks the entry of external dust and tiny particles, provides a good operating environment for the interior of the terminal box, realizes the dual functions of dustproof and heat dissipation, and ensures the stable operation of the outdoor terminal box of the substation.

[0030] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
