Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformers, in particular to cooling equipment for box-type transformers. Background Art

[0002] Box-type transformers, referred to as box transformers, are traditional transformers designed in a box-type housing. They are small in size, light in weight, low in noise, low in loss, and high in reliability. They are widely used in residential areas, commercial centers, light stations, airports, factories, mines, enterprises, hospitals, schools and other places. Box-type transformers are a complete set of power distribution equipment, which is composed of transformers, high-voltage voltage control equipment, and low-voltage voltage control equipment. The basic principle is to reasonably assemble the pressure starting system, armored wire, substation automatic system, DC system and corresponding technical equipment in the prescribed order, and install all components in a specific waterproof, dustproof and rat-proof fully sealed tempered box structure to form a specific transformer. Box-type transformers have been widely used in power engineering construction.

[0003] In the prior art, because the box-type transformer has the advantage of occupying a small space, the internal integration space is narrow. When high temperature is generated during long-term operation, in order to avoid excessive internal temperature, it is necessary to use air conditioning to assist in cooling and cooperate with the ventilation system to maintain internal operation stability. However, due to the narrow internal integration space, its traditional ventilation method only relies on exhaust fan equipment, and its heat dissipation efficiency is insufficient. It is impossible to quickly reduce the internal high temperature, which poses a safety hazard. For this reason, we propose a cooling device for box-type transformers. Utility Model Content

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] The utility model provides Figure 1-4 A cooling device for a box-type transformer is shown, comprising a main frame 1, a ventilation plate 2 is engaged in the middle of the main frame 1, and a fan 3 is connected to the front end of the main frame 1, the main frame 1 comprises a mounting frame 101, and mounting plates 102 are distributed at both ends of the mounting frame 101, bolts 103 are distributed on both sides of the mounting plate 102, and plate frame grooves 203 are opened on the inner walls at both ends of the mounting frame 101.

[0028] In order to improve the stability of the use process, such as Figure 1 As shown, when the cooling device is in use, the mounting frame 101 can be used to cooperate with the mounting plates 102 at both ends to be fixed to the inner wall of the box-type transformer, and the placement position must ensure that the box-type transformer has a reserved window. The mounting frame 101 is fixed to the window structure completely by the mounting plate 102 and the bolts 103 to ensure the stability of the overall ventilation and cooling process.

[0029] like Figure 2-3 As shown, the ventilation plate 2 includes a plate frame 201, and brackets 202 are arranged at both ends of the plate frame 201, the outer wall of the bracket 202 is fitted with a plate frame groove 203, and the back of the plate frame groove 203 is connected with a structural rod 204, a dustproof mesh frame 205 is fitted on one side of the structural rod 204, and a ventilation hole 206 is arranged inside the plate frame 201, and a compression chamber 207 is opened around the inner wall of the ventilation hole 206.

[0030] In order to improve the internal cooling efficiency of the installed box-type transformer, Figure 2-3 As shown, during use, the cooling device can be ventilated through multiple sets of ventilation holes 206 distributed inside the plate frame 201, and during the ventilation process, the conical compression chamber 207 structure of the inner wall can be used to compress and cool the inhaled air, and the low-temperature gas can be blown into the transformer to increase the overall internal cooling speed. The plate frame 201 can be combined with the dustproof grid 205 to reduce the entry of dust generated during the ventilation process, and the plate frame 201 can also be taken out of the plate frame slot 203 at any time, and the blowing direction can be changed in conjunction with the fan 3. The structure is simple and easy to adjust and use, and the cooling efficiency is high.

[0031] like Figure 4 As shown, the fan 3 includes a fan frame 301, and a fan blade 302 is arranged in the middle of the fan frame 301, connecting strips 303 are distributed at both ends of the fan frame 301, and screws 304 are distributed at both ends of the connecting strip 303, and one side of the connecting strip 303 is attached to the main frame 1.

[0032] Finally, in order to maintain stable ventilation efficiency and facilitate maintenance, Figure 4 As shown, this cooling device forms the main driving force for ventilation by mounting the fan rack 301 on the front end of the mounting frame 101, and the mounting frame 101 itself is connected and fixed by the connecting strips 303 and screws 304 at both ends of the fan rack 301, which is convenient for removal and installation.

[0033] In summary, when using the cooling device, firstly, a plurality of windows of corresponding sizes to the mounting frame 101 are opened around the installed box-type transformer, and then the mounting frame 101 is aligned with the windows, and then the mounting plates 102 and bolts 103 on both sides of the mounting frame 101 are tightened and fixed. After the mounting frame 101 is installed, the plate frame 201 is slid into the plate frame groove 203 through the clamping frames 202 on both sides, so that the conical opening of the ventilation hole 206 faces inward, and then the fan frame 301 and the mounting frame 101 are screwed together. The fan frame 301 is connected and fixed with the wire 304. When it is installed and used, the fan frame 301 drives the fan blades 302 to rotate to draw air from the outside of the transformer to the inside. The air enters the ventilation hole 206 after being filtered by the dustproof grid 205. At the same time, the progressive conical compression chamber 207 in the ventilation hole 206 gradually compresses the air to form a relatively low-temperature gas that enters the transformer to complete the cooling process. When compression is not needed, it is only necessary to pull out the plate frame 201, and then the fan frame 301 rotates in the opposite direction to blow out the internal high temperature.
