[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] The utility model provides, for example Figure 1-3 The diagram illustrates a power transformer designed to prevent external damage. It includes an oil tank 1, which is cooled by radiators 2 located at four end faces. A nameplate 7 displaying transformer information is mounted at the front end of each radiator 2. The oil tank 1 outputs electrical energy through a low-voltage output terminal 4 located at its upper front side. A high-voltage output terminal 3 for connecting to a high-voltage power grid is located at the rear side of the upper end of the oil tank 1. A support frame 6 is mounted on the right side of the upper end of the oil tank 1, supporting an oil conservator 5 mounted at the upper end. Bases 8 are located on the left and right sides of the lower end of the oil tank 1, with load-bearing plates 9 mounted on their upper ends. The load-bearing plates 9 are supported by the upper ends of the bases 8 located on the left and right sides. The locking bolt 10 at the side position is installed with the base 8. The inside of the load-bearing plate 9 is fitted with the insertion post 11 at the left and right sides. The lower end of the insertion post 11 is fixed with the connecting plate 18. The upper end of the connecting plate 18 is fixed with the stainless steel spring 17 at the left and right sides. The other end of the stainless steel spring 17 is fixed with the load-bearing plate 9. The upper and lower ends of the load-bearing plate 9 are distributed with multiple balls 14 at the inner side. The middle inner side of the load-bearing plate 9 is fitted with the control handle 15. The upper end of the control handle 15 is fixed with the upper snap plate 13. The upper end of the upper snap plate 13 is fixed with the stainless steel bolt 12. The outer wall of the control handle 15 is fixed with the lower snap plate 16.

[0024] Inside the oil tank 1, there is a winding. The high-voltage side winding is connected to the high-voltage power supply and generates a magnetic field. This magnetic field is coupled to the low-voltage side winding through the iron core, inducing a voltage on the low-voltage side. Since the high-voltage side winding has more turns than the low-voltage side winding, under the action of magnetic coupling, the electrical energy on the high-voltage side is transferred to the low-voltage side through the iron core, realizing the voltage reduction transmission of electrical energy. The current in the winding generates a magnetic field, which in turn acts on the current in the winding, forming a self-excited magnetic field, so that the current in the winding can be transmitted stably. The winding generates a certain amount of heat during operation. The insulating oil dissipates the heat through the radiator 2, keeping the transformer's operating temperature within a safe range.

[0025] like Figure 1 and Figure 2 As shown, insulating oil is installed inside the oil tank 1. The oil tank 1 is cooled and insulated by the insulating oil when the transformer is working. The radiator 2 dissipates heat to the outside when the transformer is working. The nameplate 7 is installed on the outer wall of the radiator 2. The nameplate 7 can display the transformer model, rated capacity and rated voltage. The high voltage output terminal 3 is connected to the high voltage grid and inputs high voltage power into the transformer. The low voltage output terminal 4 is connected to the low voltage load and outputs the power after the transformer step-down to the user. The stainless steel bolt 12 is connected to the threaded hole at the lower end of the oil tank 1. The lower end of the oil tank 1 has insertion holes on the left and right sides. The insertion post 11 is inserted into the insertion hole at the lower end of the oil tank 1. The control handle 15 can control the installation of the stainless steel bolt 12 and the oil tank 1. The connecting plate 18 is installed below the load-bearing plate 9 by the stainless steel spring 17. The downward movement of the connecting plate 18 can disengage the insertion post 11 from the insertion hole of the oil tank 1.

[0026] Insertion holes are provided on the lower left and right sides of the oil tank 1. When the oil tank 1 does not need to rotate, the insertion post 11 can be inserted into the inside of the insertion hole, so that the oil tank 1 cannot rotate. When it is necessary to rotate so that the insertion post 11 is disengaged from the insertion hole, the oil tank 1 can rotate.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
