[0022] To make the technical problems, technical solutions and beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] The embodiment provided by this utility model is shown in Figures 1-3. It includes a transformer 10, an oil tank 20 fixedly mounted at the bottom of the transformer 10, the oil tank 20 mounted on a mounting bracket 30, a cooling assembly 40 fixedly mounted at the rear end of the oil tank 20, and an oil pump 50 fixedly mounted on the side wall of the oil tank 20. The input end of the oil pump 50 is connected to the oil tank 20, and the output end is connected to the cooling assembly 40. The cooling assembly 40 is used to reduce the temperature of the oil pumped by the oil pump 50. An oil inlet 60 is fixedly mounted at the front end of the oil tank 20, and a waterproofing device is provided at the front end of the oil tank 20. The anti-theft component 70 includes an anti-theft box 71, which is fixedly installed at the front end of the fuel tank 20. The rear end of the anti-theft box 71 has an anti-theft hole that matches the fuel inlet 60. The fuel inlet 60 is inserted into the anti-theft box 71 through the anti-theft hole. An anti-theft nut 72 is fixedly installed on the inner wall of the anti-theft box 71. The anti-theft nut 72 is fitted onto the fuel inlet 60 and its size matches the diameter of the fuel inlet 60. An anti-theft bolt 73 is threaded onto the anti-theft nut 72. An anti-theft opening 74 is opened at the front end of the anti-theft box 71 and is located directly in front of the anti-theft bolt 73.

[0024] During operation, the operator starts the transformer 10. The insulating oil in the oil tank 20 serves to insulate and dissipate heat for the transformer 10. As the transformer 10 operates, the temperature of the insulating oil in the oil tank 20 gradually rises. When the temperature of the insulating oil reaches a certain value, the operator starts the cooling component 40 and the oil pump 50. The oil pump 50 drives the insulating oil in the oil tank 20 into the cooling component 40 to quickly cool the high-temperature insulating oil. The cooled insulating oil then flows back into the oil tank 20. Through the above methods, the oil temperature in the oil tank 20 is maintained at a certain level. When the operator needs to add oil to the oil tank 20, the operator inserts the anti-theft bolt 73 into the anti-theft box 71 through the anti-theft port 74 and unscrews the anti-theft bolt 73. The operator then inserts the external oil pipe into the oil inlet 60 through the anti-theft nut 72 and then adds oil to the oil tank 20. After the oil is added, the operator removes the oil pipe, screws the anti-theft bolt 73 into the anti-theft nut 72, and tightens the anti-theft bolt 73.

[0025] It should be noted that the anti-theft bolt 73 is a non-standard bolt, which requires special tools to tighten. The anti-theft bolt 73 is existing technology. The structure of the anti-theft bolt 73 will not be described in detail in this solution. For reference, please refer to the Chinese utility model patent "Anti-theft device for oil-immersed transformer" with application number CN201120079403.1 and publication date of 2011.09.21.

[0026] Preferably, the cooling assembly 40 includes a cooling box 41, which is fixedly connected to the oil tank 20. A cooling oil pipe 42 is fixedly installed inside the cooling box 41. The input end of the cooling oil pipe 42 passes through the side wall of the cooling box 41 and is connected to the output end of the oil pump 50. The output end of the cooling oil pipe 42 passes through the side wall of the cooling box 41 and is connected to the oil tank 20. A butterfly valve is fixedly installed at the output end of the cooling oil pipe 42. A cooling fan 43 is fixedly connected to the rear end of the cooling box 41.

[0027] Preferably, a bracket 44 is fixedly installed inside the cooling box 41, and the cooling oil pipe 42 is fixedly installed on the bracket 44. The bracket 44 supports and fixes the condenser cooling oil pipe 42, improves the stability of the cooling oil pipe 42, avoids shaking, and has a good cooling effect.

[0028] Preferably, a support base 80 is fixedly provided around the outer side of the anti-theft nut 72. The bottom of the support base 80 is fixedly connected to the inner side wall of the anti-theft box 71. The support base 80 provides support and fixation for the anti-theft nut 72, preventing the anti-theft nut 72 from shaking and affecting the anti-theft effect.

[0029] Preferably, a first baffle 90 is vertically installed inside the anti-theft box 71. The left and right sides of the first baffle 90 are fixedly connected to the inner sidewall of the anti-theft box 71, respectively. The end of the anti-theft nut 72 away from the oil inlet 60 abuts against the first baffle 90. The anti-theft bolt 73 passes through the first baffle 90, and the nut abuts against the side of the first baffle 90 away from the anti-theft nut 72. The first baffle 90 plays a positioning role. Since the anti-theft nut 72 is set inside the anti-theft box 71, the first baffle 90 can help the staff determine the position of the anti-theft nut 72, making it convenient for the staff to install the anti-theft bolt 73.

[0030] Preferably, a second baffle 100 is horizontally arranged inside the anti-theft box 71. The left and right sides of the second baffle 100 are fixedly connected to the inner sidewall of the anti-theft box 71, respectively. The top of the first baffle 90 is fixedly connected to the upper surface of the inner wall of the anti-theft box 71, the bottom is fixedly connected to the rear end of the second baffle 100, and the front end of the second baffle 100 is fixedly connected to the front inner sidewall of the anti-theft box 71. The second baffle 100 is located below the anti-theft opening 74. The first baffle 90, the second baffle 100, and the inner wall of the anti-theft box 71 together form a sealed space. When the staff pours oil into the oil inlet 60, this arrangement can prevent the insulating oil from dripping to the bottom of the anti-theft box 71, making it easy for the staff to clean up the overflowing insulating oil.

[0031] Preferably, a level gauge 110 is fixedly installed on the oil tank 20, which makes it easier for staff to monitor the oil level in the oil tank 20 and makes it more convenient to use.

[0032] Preferably, an installation plate 120 is fixedly installed on the side wall of the oil tank 20, and the oil pump 50 is installed on the installation plate 120, which facilitates the installation and replacement of the oil pump 50 by the staff and improves work efficiency.

[0033] Preferably, a support rod 130 is horizontally fixed on the mounting frame 30. The support rod 130 is used to improve the stability of the mounting frame 30 and prevent the mounting frame 30 from shaking when the device is moved.

[0034] Preferably, casters 140 are fixed at the four corners of the bottom of the mounting bracket 30 to facilitate the movement of the device by the staff and make it easier to use.

[0035] The working principle of this embodiment, and its more specific process, are as follows:

[0036] When the operator starts the transformer 10, the insulating oil in the oil tank 20 serves to insulate and dissipate heat for the transformer 10. As the transformer 10 operates, the temperature of the insulating oil in the oil tank 20 gradually rises. When the temperature of the insulating oil reaches a certain value, the operator starts the cooling assembly 40 and the oil pump 50. The oil pump 50 drives the insulating oil in the oil tank 20 into the cooling oil pipe 42. The cooling fan 43 accelerates the airflow, removing the heat from the insulating oil in the cooling oil pipe 42 through heat exchange. Then, the heat is removed from the output end of the cooling oil pipe 42. When the butterfly valve is opened, the ambient temperature insulating oil flows back into the oil tank 20. Through the above method, the oil temperature in the oil tank 20 is always maintained within a certain range. When the staff needs to add oil to the oil tank 20, the staff extends into the anti-theft box 71 through the anti-theft port 74 and unscrews the anti-theft bolt 73. The staff inserts the external oil supply pipe into the oil filling port 60 through the anti-theft nut 72 and then supplies oil into the oil tank 20. After the oil supply is completed, the staff removes the oil supply pipe, screws the anti-theft bolt 73 into the anti-theft nut 72, and tightens the anti-theft bolt 73.

[0037] It should be noted that the transformer 10, cooling fan 43, and level gauge 110 in this solution are existing technologies. Any equipment that can achieve the above functions can be selected according to the usage parameters. Therefore, their structures are not described in this solution.

[0038] This utility model discloses an anti-theft oil-immersed transformer. An anti-theft component 70 is installed at the front end of the oil tank 20. The anti-theft component 70 includes an anti-theft box 71, which is fixedly installed at the front end of the oil tank 20. An anti-theft hole matching the oil inlet 60 is opened at the rear end of the anti-theft box 71. The oil inlet 60 is inserted into the anti-theft box 71 through the anti-theft hole. An anti-theft nut 72 is fixedly installed on the inner wall of the anti-theft box 71. The anti-theft nut 72 is fitted onto the oil inlet 60, and its size matches the diameter of the oil inlet 60. An anti-theft bolt 73 is threaded onto the anti-theft nut 72. This design effectively prevents oil theft from occurring, reduces maintenance costs, and saves resources.
