[0002] A three-phase transformer is an electrical device that can transform three-phase alternating current from one voltage level to another. It typically consists of a high-voltage winding, a low-voltage winding, an iron core, and an oil tank.

[0026] Please see Figure 1-3This utility model provides an embodiment of an oil-immersed three-phase transformer: An oil-immersed three-phase transformer includes a transformer body 1 and a protective cover 2. The transformer body 1 includes heat dissipation fins 101 and insulators 102. Multiple sets of heat dissipation fins 101 are evenly arranged on the outer side of the transformer body 1, allowing heat dissipation to the transformer body 1 and preventing damage due to overheating. Multiple sets of insulators 102 are arranged and installed on the top of the transformer body 1. The protective cover 2 includes a duct 202, an air inlet pipe 204, a blower 205, and an air outlet 207. The duct 202 is located below the bottom of the protective cover 2, and two sets of air inlet pipes 204 are symmetrically arranged at the front end of the top of the duct 202. At the rear end, a blower 205 is located at one end of the air inlet duct 204, which can generate airflow to reduce the temperature of the heat dissipation fins 101. Multiple sets of air outlets 207 are evenly distributed at the bottom of the air duct 202 to blow cool air onto the heat dissipation fins 101, thereby improving the heat dissipation effect of the three-phase transformer. A solar panel 201 is installed on the top of the protective cover 2 to power the blower 206 and reduce the heat dissipation power consumption of the transformer. Connecting posts 203 are provided at the four corners of the bottom of the protective cover 2 to install and fix the air duct 202, making the use of the three-phase transformer more stable. Mounting blocks 206 are provided at both ends of the top of the protective cover 2 to install the blower 205 on the top of the transformer body 1.

[0027] Please refer to this carefully. Figure 1 and Figure 3 The transformer body 1 has mounting brackets 3 on both sides of the bottom. The protective cover 2 can be installed on the top of the transformer body 1 through the mounting brackets 3. The transformer body 1 has mounting seats 301 on both sides of the bottom. The top of the two sets of mounting seats 301 is equipped with bow-shaped brackets 302, which have a shock absorption effect and make the installation and use of the transformer body 1 more stable.

[0028] Please refer to this carefully. Figure 1 and Figure 2 The transformer body 1 has multiple sets of mounting holes on its top, and sealing rings are provided on the inner side of the mounting holes. The transformer body 1 has windings inside, and insulators 102 are connected to the windings through the mounting holes, so that the insulators 102 can be fixedly installed on the top of the transformer body 1, which facilitates the installation and use of the three-phase transformer. One end of each of the two sets of air inlet pipes 204 is welded to the outside of the air duct 202, and the air inlet pipes 204 and the air duct 202 are connected. The blower 205 is detachably connected to the other end of the air inlet pipe 204 through fixing bolts, and the blower 205 is installed and used at one end of the air inlet pipe 204. The blower 205 is connected to the air duct 202 through the air inlet pipe 204, and the generated air force can be delivered to the inside of the air duct 202. The air inlets of the two sets of blowers 205 are equipped with protective nets to prevent debris from entering the blower 205 and causing damage.

[0029] Please refer to this carefully. Figure 1 and Figure 3 The transformer body 1 has a mounting groove on its top. A solar panel 201 is detachably connected to a protective cover 2 via this groove, allowing the solar panel 201 to be mounted on top of the protective cover 2. The solar panel 201 is electrically connected to a blower 205 via the transformer, providing power to the blower 205 and reducing the transformer's heat dissipation. Both sets of mounting blocks 206 are welded to the top of the transformer body 1. The blower 205 is detachably connected to the mounting blocks 206 via fixing bolts, allowing the blower 205 to be mounted on top of the mounting blocks 206, thus ensuring more stable operation of the blower 205. The bottom end of the connecting column 203 is welded to the air duct 202. The air duct 202 is fixedly connected to the protective cover 2 through the connecting column 203. The air duct 202 can be fixed to the bottom of the protective cover 2 through the connecting column 203. The top ends of the two sets of mounting brackets 3 are welded to the bottom of the protective cover 2. The protective cover 2 is fixedly connected to the transformer body 1 through the two sets of mounting brackets 3. The mounting brackets 3 can support and fix the protective cover 2. The two sets of mounting seats 301 are detachably connected to the transformer body 1 through fixing bolts, which facilitates the stable installation of the transformer body 1 and makes the use of the three-phase transformer more stable.

[0030] Working principle: Before use, two sets of mounting brackets 301 are installed at the bottom of the transformer body 1 using fixing bolts. The transformer is stably installed by the support of the two sets of mounting brackets 301. When in use, the power is turned on, and the protective cover 2 is fixed to the transformer body 1 by the two sets of mounting brackets 3. The transformer body 1 is cooled by the heat dissipation fins 101. The blower 205 generates air force, which is delivered to the inside of the air duct 202 through the air inlet duct 204. The air force is blown to the heat dissipation fins 101 through the air outlet 207, which can reduce the temperature on the heat dissipation fins 101, thereby facilitating the cooling of the transformer body 1. The solar panel 201 on the top of the protective cover 2 can provide power to the blower 205, which can reduce the heat dissipation power consumption of the transformer, reduce the operating cost of the three-phase transformer, and thus improve the service life of the three-phase transformer.
