[0038] The working principle of the present invention is as follows: during use, the three-phase oil-immersed transformer body 1 is stably placed at the position where it needs to be used through the support legs 2. The support legs 2 can support and fix the three-phase oil-immersed transformer body 1, which is convenient for the stable use of the three-phase oil-immersed transformer body 1. After the three-phase oil-immersed transformer body 1 is stably placed, the three-phase oil-immersed transformer body 1 is further installed and fixed. After the three-phase oil-immersed transformer body 1 is installed and fixed, the power line that needs to be transformed is connected to the three-phase oil-immersed transformer body 1, and further Open the three-phase oil-immersed transformer body 1. When the three-phase oil-immersed transformer body 1 is opened, the three-phase oil-immersed transformer body 1 can transform the power of the power line that needs to be transformed for use. During the use of the three-phase oil-immersed transformer body 1, a certain amount of heat will be generated in the three-phase oil-immersed transformer body 1. The oil in the oil reservoir 7 is further transported to the three-phase oil-immersed transformer body 1. The oil in the oil reservoir 7 enters the three-phase oil-immersed transformer body 1, which can insulate and cool the three-phase oil-immersed transformer body 1, thereby facilitating the normal use of the three-phase oil-immersed transformer body 1.
[0039] When the oil enters the three-phase oil-immersed transformer body 1 to cool the three-phase oil-immersed transformer body 1, the temperature of the oil will rise. In order to ensure the normal use of the three-phase oil-immersed transformer body 1, when the temperature of the oil rises, the oil needs to be replaced, and the second oil pump 4 is further opened. When the second oil pump 4 is opened, the second oil pump 4 can extract the oil carrying heat in the connected three-phase oil-immersed transformer body 1, and the second oil pump 4 can transport the extracted oil to the oil cooling box 8 through the second connecting pipe 6. The second connecting pipe 6 allows the oil to pass through the oil cooling box 8. The cover plate 26 at the upper end enters the oil cooling box 8. After the oil enters the oil cooling box 8, it will fall onto the heat absorbing mesh plate 9. After the oil falls onto the heat absorbing mesh plate 9, it will fall through the heat absorbing mesh plate 9. In the process of the oil falling through the heat absorbing mesh plate 9, the heat absorbing mesh plate 9 can absorb the heat carried by the oil. The heat absorbing mesh plate 9 enables the oil to fall evenly, which helps the heat absorbing mesh plate 9 to absorb the heat in the oil. After the oil falls to the bottom of the oil cooling box 8 through the heat absorbing mesh plate 9, the heat absorbing block 10 can absorb the heat remaining in the bottom oil that falls into the oil cooling box 8.

The thermoelectric device 19 can transport the converted electrical energy to the electrically connected rotating motor 13 for the rotating motor 13 to be turned on and used. When the rotating motor 13 is turned on, the output end of the rotating motor 13 can drive the connecting disk 14 to rotate. During the rotation of the connecting disk 14, the connecting disk 14 can drive the first connecting rod 15 and the second connecting rod 15 to rotate. The rod 16 rotates, and during the rotation of the first connecting rod 15 and the second connecting rod 16, the first connecting rod 15 and the second connecting rod 16 can stir the oil in the oil cooling tank 8, which helps to cool the oil in the oil cooling tank 8 and improve the working efficiency of the oil cooling. The heat collected by the heat recovery device 11 can be transported to the first heat-conducting rod 20, and the heat is transferred to the second heat-conducting rod 21 fixedly connected to the first heat-conducting rod 20 through the first heat-conducting rod 20. The heat insulation sleeve 23 on the outside of the first heat-conducting rod 20 can insulate the first heat-conducting rod 20 to prevent heat loss on the first heat-conducting rod 20, which helps the first heat-conducting rod 20 to transfer heat.
[0041] The second heat-conducting rod 21 can transfer heat to the connected third heat-conducting rod 22, the first heat-conducting plate 24 and the second heat-conducting plate 25. The heat carried by the second heat-conducting rod 21, the third heat-conducting rod 22, the first heat-conducting plate 24 and the second heat-conducting plate 25 can heat the air on the upper side of the three-phase oil-immersed transformer main body 1, and can evaporate the moisture in the air on the upper side of the three-phase oil-immersed transformer main body 1, thereby preventing the air humidity on the upper side of the three-phase oil-immersed transformer main body 1 from affecting the use of the three-phase oil-immersed transformer main body 1. If the three-phase oil-immersed transformer main body 1 is installed outdoors, when it snows in winter, snowflakes will adhere to the three-phase oil-immersed transformer main body 1. When more snow accumulates on the three-phase oil-immersed transformer main body 1, it is easy to affect the three-phase oil-immersed transformer main body 1. The use of the three-phase oil-immersed transformer body 1, the heat carried by the second heat-conducting rod 21, the third heat-conducting rod 22, the first heat-conducting plate 24 and the second heat-conducting plate 25 can melt the snow, thereby preventing the snow from accumulating on the three-phase oil-immersed transformer body 1 and affecting the use of the three-phase oil-immersed transformer body 1, and facilitating the normal use of the three-phase oil-immersed transformer body 1. After the oil in the oil cooling tank 8 is cooled, the first oil pump 3 is turned on. When the first oil pump 3 is turned on, the first oil pump 3 can extract the cooled oil in the connected oil cooling tank 8, and the first oil pump 3 can transport the extracted oil to the oil storage cylinder 7 through the first connecting pipe 5, so as to facilitate the recycling of the oil.
[0042] During use, the heat carried by the oil can be collected during the cooling process of the oil carrying heat, which helps to recycle the heat carried by the oil, improve the working efficiency of the oil cooling in the three-phase oil-immersed transformer body 1, and help to use the three-phase oil-immersed transformer in an energy-saving and environmentally friendly manner.
[0043] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
