[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is widely used in industries, agriculture, transportation, urban communities, and other fields. In the existing power supply system, the transformer usually uses an oil-immersed transformer, which is mainly composed of an iron core, a winding, an oil tank, heat sink fins, an oil pillow, and other parts. The oil tank is the outer shell of the oil-immersed transformer, and other components are fixedly installed in the oil tank. The heat sink fins are installed on the outer wall of the oil tank. When the transformer is working, a large amount of heat will be generated. If the heat is not dissipated in time, it will directly affect the operation of the transformer, which will shorten the service life of the transformer at the least, and directly damage the transformer at the worst. The heat dissipation performance of the transformer currently used is average. In actual use, heat sink fins are set on both sides of the transformer. The heat dissipation area of ​​the transformer is limited, and the internal temperature cannot be fully and effectively dissipated.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0019] like Figure 1 As shown, a transformer with high stability of the present invention comprises an oil tank 1 and a bracket 2, wherein the transformer body is installed in the oil tank 1, and a plurality of heat dissipation fins 3 are distributed on the outer surface of the oil tank 1, and the bracket 2 is fixed to the bottom of the oil tank 1, and the bracket 2 has bolt holes, and is characterized in that it also comprises a heat dissipation unit and a fixing assembly, and the outer side surface of the oil tank 1 has longitudinally arranged heat dissipation fins 3, and each heat dissipation fin 3 is distributed at intervals; a heat dissipation unit is also provided on the outer side surface of the oil tank 1, and the heat dissipation unit is located below the heat dissipation fin 3, and each heat dissipation unit comprises a ventilation pipe 4 and two groups of air guide units, the ventilation pipe 4 is hollow inside and open at both ends, and the two groups of air guide units are symmetrically distributed in the ventilation pipe 4. As shown Figure 2 As shown, each group of air guide units includes a plurality of air guide fins 5, which are distributed at intervals, one end of the air guide fin 5 is fixed to the inner wall of the ventilation duct 4, and the other end of the air guide fin 5 is a free end, and the free end of the air guide fin 5 is inclined toward the opening of the ventilation duct 4 close to it, and the length of the air guide fin 5 of each group of air guide units gradually increases from the opening close to the ventilation duct 4 to the middle of the ventilation duct 4, and a plurality of through holes 4-1 are opened on the ventilation duct 4, and the through holes 4-1 are distributed in the gap between two adjacent air guide fins 5, and each through hole 4-1 corresponds to a heat dissipation fin 3 above the heat dissipation unit.

[0020] like Figure 1As shown, the bracket 2 is fixed by a fixing assembly, and the fixing assembly includes a fixing plate 6 and a pressure block 7. The pressure block 7 is Z-shaped, and the upper transverse section of the Z-shaped pressure block 7 abuts against the bracket 2, and the lower transverse section of the Z-shaped pressure block 7 abuts against the fixing plate 6, and the lower transverse section of the Z-shaped pressure block 7 is fixedly connected to the fixing plate 6 by a longitudinal positioning bolt 8. A strip hole 6-1 is opened on the fixing plate 6, and the longitudinal positioning bolt 8 is passed through the strip hole 6-1. The bracket 2 and the fixing plate 6 are fixed by a lateral positioning bolt 9, and the lateral positioning bolt 9 is passed through the bolt hole and the strip hole 6-1.

[0021] The bracket 2 is two C-shaped channel steels, and each C-shaped channel steel is fixed by a fixing component.

[0022] The fixing plate 6 is fixed to the surface to which the transformer is to be fixed by means of fastening bolts 10 .

[0023] Each outer side surface of the oil tank 1 is provided with a heat dissipation fin 3 and a heat dissipation unit.

[0024] The heat dissipation fins 3 are evenly spaced and distributed, the air guide fins 5 are evenly spaced and distributed, and the length of the air guide fins 5 of each group of air guide units gradually and evenly increases from the opening of the ventilation pipe 4 to the middle of the ventilation pipe 4.

[0025] The two groups of air guide units are symmetrically distributed about the perpendicular bisector of the ventilation pipe 4 where they are located.

[0026] A transformer with high stability of the present invention is provided with a heat dissipation unit below the heat dissipation fins 3, thereby improving the heat dissipation effect. The heat dissipation unit is very clever, wherein the ventilation pipe 4 is open at both ends, and each outer surface of the oil tank 1 is provided with a heat dissipation unit, that is, different surfaces of the oil tank 1 have ventilation pipes 4 with both ends open, thus obtaining openings of the ventilation pipes 4 facing different directions, thus increasing the air inlet direction of the ventilation pipe 4, and when the wind direction outside the transformer changes, the air inlet rate of the ventilation pipe 4 can be increased, and the wind blows through the air guide fins 5 in the ventilation pipe 4, taking away the heat, thereby improving the heat dissipation effect. In addition, the air guide fins 5 inside the ventilation duct 4 are inclined and gradually lengthened, so that the air guide fins 5 can intercept the wind flow section by section. Each air guide fin 5 guides the wind to each through hole 4-1 in turn from the air inlet of the ventilation duct 4 and discharges it from the through hole 4-1. The wind is intercepted section by section by the air guide fins 5 of different lengths, and the wind flow is discharged from each through hole 4-1. The wind flow will take away the heat on the air guide fins 5. At the same time, the wind discharged from the through hole 4-1 just blows onto the heat dissipation fins 3 corresponding to the through hole 4-1, taking away the heat on the heat dissipation fins 3, thereby accelerating the heat dissipation of the heat dissipation fins 3 and further improving the heat dissipation effect. The fixing assembly of the present invention can be universal for different transformer brackets. The strip hole 6-1 on the fixing plate 6 can allow for the uncertainty of the position of each bolt. The inner diameter of the strip hole 6-1 is smaller than each bolt, including the longitudinal positioning bolt 8, the lateral positioning bolt 9 and the tightening bolt 10, and the outer diameter of the nut provided. Each bolt passes through the strip hole 6-1. After the nut is screwed on, the bolt can be fixed to the fixing plate 6. The position of the Z-shaped pressing block 7 can be moved and adjusted along the strip hole 6-1 on the fixing plate 6 to adapt to the brackets 2 of different positions and different sizes and widths. If the upper and lower transverse sections of the Z-shaped pressing block 7 cannot make the Z-shaped pressing block 7 butt against the bracket 2 or the Z-shaped pressing block 7 butt against the fixing plate 6 due to thickness reasons, the butt can be achieved by adding a gasket between the Z-shaped pressing block 7 and the bracket 2 or between the Z-shaped pressing block 7 and the fixing plate 6. The insertion of the longitudinal positioning bolt 8 realizes the longitudinal fixation of the bracket 2, that is, the transformer; the insertion of the lateral positioning bolt 9 realizes the lateral fixation of the bracket 2, that is, the transformer; the tightening bolt 10 realizes the fixation of the fixing plate 6 to the required fixing surface of the transformer.

[0027] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
