Technical Field

[0001] The utility model relates to the technical field of electric power equipment and discloses a power transformer. Background Art

[0002] The power transformer is a soft magnetic electromagnetic component that provides power transmission, voltage conversion and insulation isolation for the power supply. According to the size of the transmitted power, the power transformer can be divided into several stages: high power, medium power, low power and micro power. The design of the power transformer is different for different transmission powers.

[0003] The patent with the patent authorization publication number CN218826484U discloses a power transformer, including a shell, a connection assembly is arranged on the side of the shell, a top plate is connected to the top of the shell, and a top plate through hole is opened inside the top plate. Although the above patent sets a sealing assembly to make the slide block the top plate through hole under the action of spring 2 to prevent dust from entering the shell, the actual temperature inside the power transformer is much higher than that outside. When the internal temperature of the power transformer is too high, the power transformer cannot be protected from overheating, which may easily cause safety hazards.

[0004] In view of this, a power transformer with an overheat protection function is needed to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1: A power transformer, see Figure 1-Figure 6, including a transformer body 1, an adjustment disk 2, a mounting shell 4, a mounting block 5, an electrical connection 6 and a thermistor 7. An adjustment disk 2 is arranged on the top of the transformer body 1, and the transformer body 1 is adjusted by rotating the adjustment disk 2. The transformer body 1 is provided with a mounting shell 4 by welding, and a mounting block 5 is arranged inside the mounting shell 4 by welding. The mounting shell 4 is connected with an electrical connection 6, and the electrical connection 6 is connected to the mounting block 5. The mounting shell 4 is connected with a thermistor 7, and the thermistor 7 contacts the mounting block 5. When the temperature inside the transformer body 1 is too high, the thermistor 7 will be deformed. It also includes a connector 3, and the connector 3 is connected to the bottom of the transformer body 1. A connecting port is opened on the top of the transformer body 1. It also includes a protective cover 21, and the top of the transformer body 1 is covered with a protective cover 21. The protective cover 21 shields the connecting port to prevent dust and other impurities from falling into the connecting port.

[0030] When the power transformer is needed, the staff picks up the transformer body 1, plugs the connector 3 into the power supply, connects the transformer body to the power supply, and then rotates the adjustment disk 2 to adjust the transformer body, so that the transformer body 1 converts the voltage of the power supply. When the internal temperature of the transformer body 1 is too high, the thermistor wire 7 is deformed and loses contact with the mounting block 5, thereby cutting off the power to the transformer body 1, thereby protecting the power transformer and the power supply to avoid safety hazards. The protective cover 21 protects the connection port to prevent foreign objects from falling into the connection port.

[0031] Example 2: Based on Example 1, please refer to Figure 1 and Figure 4 , also includes a first rotating rod 8, a clamping plate 9, a torsion spring 10, a second rotating rod 11 and a rotating plate 12. Two first rotating rods 8 are arranged at the bottom of the transformer body 1 by welding. The clamping plate 9 is rotatably arranged on the first rotating rod 8. Two torsion springs 10 for resetting the clamping plate 9 are sleeved on the first rotating rod 8. The clamping plate 9 is provided with a second rotating rod 11 by welding. The rotating plate 12 is rotatably arranged on the second rotating rod 11. It also includes a fixing bolt 13. The fixing bolt 13 is slidably arranged on the rotating plate 12. It also includes a magnetic block 22. The rotating plate 12 is provided with a magnetic block 22. The magnetic block 22 fixes the rotating plate 12 to the power supply.

[0032] When the transformer needs to be fixed, the staff rotates the clamping plate 9 downward to make the clamping plate 9 perpendicular to the transformer body 1, and the torsion spring 10 returns to its original shape to rotate the clamping plate 9 upward to clamp the power supply, and then rotates the rotating plate 12 upward to make it located on both sides of the power supply, thereby fixing the transformer body 1 on the power supply, thereby preventing the transformer body 1 from moving.

[0033] See also Figure 5 and Figure 6, also includes a first mounting plate 14, a condenser 15 and a ventilation fan 16. A plurality of first mounting plates 14 are arranged on the left and right sides of the transformer body 1 by welding. The plurality of first mounting plates 14 are evenly spaced. A plurality of condenser 15 are arranged on the plurality of first mounting plates 14 by bolt connection. A plurality of ventilation fans 16 are arranged on the left and right sides of the transformer body 1 by bolt connection. The ventilation fan 16 rotates to suck the outside air into the transformer body 1. It also includes a protective net 17. The protective net 17 is embedded on the left and right sides of the transformer body 1. The protective net 17 protects the ventilation fan 16 to prevent foreign matter from being drawn into the ventilation fan 16. It also includes a second mounting plate 18, a connecting rope 19 and a rubber sleeve 20. A second mounting plate 18 is arranged on the right side of the transformer body 1 by welding. A connecting rope 19 is connected to the second mounting plate 18. The connecting rope 19 is elastic. A rubber sleeve 20 for protection is connected to the end of the connecting rope 19.

[0034] The operation of the transformer generates heat, and the staff turns on the condenser 15 and the ventilation fan 16. The ventilation fan 16 rotates to suck the outside air into the transformer body 1. The condenser 15 cools the air, and the air continues to flow inward, thereby dissipating the heat of the transformer body 1, thereby preventing the high temperature from affecting the normal operation of the transformer. When the connector 3 is not needed, the staff picks up the connecting rope 19 and puts the rubber sleeve 20 on the connector 3, thereby protecting the connector 3, thereby preventing the connector 3 from oxidation and rusting.
