Technical Field

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux intersecting the coil changes. This is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance. Transformers are basic equipment for power transmission and distribution, and are widely used in industries such as industry, agriculture, transportation, and urban communities.

[0025] See also Figure 1-3 The utility model provides a technical solution: an oil-cooled transformer, comprising a transformer 1, the transformer 1 being a rectangular parallelepiped structure, a bracket 2 for supporting equipment being fixedly provided at the bottom of the transformer 1, a high-voltage bushing 3 for ground insulation due to the equipment inlet and outlet lines and high-voltage circuits passing through objects being fixedly provided at the top of the transformer 1, a shell 4 being fixedly provided on the outside of the transformer 1, a heat dissipation oil channel 5 for heat dissipation being provided inside the shell 4, a mounting hole being reserved on the shell 4, a frame 7 being connected to the shell 4 by bolts through the mounting holes, the frame 7, a condenser 8 being fixedly provided on one side of the frame 7, an oil inlet 11 and an oil outlet 12 being fixedly provided on the top of the condenser 8 on the frame 7, and a fan 13 for rapid heat dissipation being fixedly provided on the other side of the frame 7.

[0026] In the above technical solution, if Figure 1 As shown, through the built-in heat dissipation oil channel 5 and the external condenser 8, the transformer 1 can be quickly cooled, so that the equipment has a better temperature control effect and can maintain good working conditions. The external heat dissipation device makes the internal cooling oil have a better heat dissipation effect, so that the heat dissipation performance of the equipment is better and more practical. The oil inlet 11 and the oil outlet 12 on the condenser 8 are connected to the oil channel in the shell 4, so that the equipment has a faster heat dissipation efficiency.

[0027] In the technical solution of the utility model, if Figure 3 As shown, two groups of brackets 2 are horizontally and symmetrically arranged on both sides of the bottom end of the transformer 1. The two groups of brackets 2 increase the stability of the device and provide the device with better structural stability.

[0028] In the technical solution of the utility model, if Figure 1 As shown, the outer side of the shell 4 is fixedly provided with heat dissipation fins 6 for increasing the heat dissipation effect. By installing the heat dissipation fins 6 on the outer side of the shell 4, the heat dissipation effect of the device is significantly increased, so that the device has a better heat dissipation effect.

[0029] In the technical solution of the utility model, if Figure 1 As shown, four groups of fixing holes 9 are fixed at the rectangular geometric corners on one side of the frame 7, and the frame 7 is bolted to the shell 4 through the fixing holes 9. This design makes the device and the external cooling mechanism have better stability and better quick disassembly through bolt connection, making the device more practical.

[0030] In the technical solution of the utility model, if Figure 2 As shown, the fan 13 includes a drive motor 14 fixedly mounted on a frame 7 and arranged horizontally, and a fan blade 15 is fixedly mounted on the output end of the drive motor 14. By cooling the fan 13, the heat exchange efficiency of the condenser 8 can be accelerated, so that the cooling oil inside the equipment can be better dissipated, and the equipment has better heat dissipation efficiency.

[0031] In the technical solution of the utility model, if Figure 1 As shown, the frame 7 is fixedly provided with a grille 10 for protecting the device on the left side of the fan 13. The grille 10 can effectively prevent foreign objects from getting stuck in the cooling fan 13, ensuring the normal operation of the device while making the device safer.

[0032] When in use, a large amount of heat will be generated under the continuous operation of the transformer 1. At this time, the cooling oil in the oil channel inside the shell 4 will continue to absorb heat. At the same time, the temperature of the cooling oil will continue to be reduced through the condenser 8 connected to the oil channel, so that the equipment always maintains a good heat dissipation effect. At the same time, the heat dissipation effect of the equipment is further enhanced by the heat dissipation fan 13. At the same time, oil cooling is adopted for heat dissipation. Since the specific heat capacity of the cooling oil is larger than that of the coolant, and the low-temperature applicability of the cooling oil is stronger, the equipment not only has a heat dissipation effect that exceeds that of water cooling, but also has stronger low-temperature adaptability, so that the equipment has better practicality.
