Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a power transformer. Background Art

[0002] The transformer principle was first discovered by Faraday, but it was not put into practical use until the 1880s. In the competition between power plants that should output direct current and alternating current, one of the advantages of alternating current is that it can use transformers. Transformers can convert electrical energy into high voltage and low current forms, and then convert them back again, thus greatly reducing the loss of electrical energy during transmission, making it economical to transmit electrical energy over longer distances. In this way, power plants can be built far away from where electricity is used.

[0003] Existing transformers are cooled by cooling fans to prevent the transformer from being damaged due to excessive temperature. Generally, cooling fans are installed on the top and left and right sides of the transformer. On rainy days, rainwater can easily fall into the transformer from the cooling fan installation location, causing damage to the transformer. Utility Model Content

[0024] In order to buffer and reduce shock for the installation box 3, thereby ensuring the stability and safety of the installation box 3 and improving the service life of the installation box 3, support rods 15 are fixedly connected to the left and right sides of the inner wall of the outer frame 2 near the bottom. There are two support rods 15, and the two support rods 15 are arranged opposite to each other front and back. The left and right ends of the surface of each support rod 15 are movably sleeved with connecting blocks 16, and the top surface of each connecting block 16 is hinged with a support plate 17. The tops of the four support plates 17 are respectively hinged to the four corners of the bottom surface of the installation box 3, and springs 18 are sleeved on both ends of the surface of each support rod 15. One end of the spring 18 is fixedly connected to the connecting block 16, and the other end of the spring 18 is fixedly connected to the inner wall of the outer frame 2.

[0025] In order to support the connecting block 16 and reduce the pressure on the support rod 15, thereby improving the stability of the support rod 15 and at the same time not increasing the friction resistance of the connecting block 16 moving left and right, the bottom surface of the connecting block 16 is fixedly connected with a pulley 19, and the pulley 19 is slidably connected to the top surface of the mounting seat 1.

[0026] In order to support the left and right sides of the exhaust frame 13 and improve the stability of the exhaust frame 13, support blocks 20 are fixedly connected to the left and right sides of the bottom surface of the exhaust frame 13, and the bottom surface of the support block 20 is fixedly connected to the top surface of the outer frame 2.

[0027] For this purpose, the left and right sides of the front face of the installation box 3 are both hingedly connected with the first door panels 21 , and the left and right sides of the front face of the outer frame 2 are both hingedly connected with the second door panels 22 .

[0028] In order to improve the rainproof effect of the air intake pipe 8 and prevent rainwater from falling or splashing into the interior of the installation box 3, the air intake pipe 8 is L-shaped, and the air intake end of the air intake pipe 8 is arranged downward.

[0029] In order to ensure the speed of hot air discharge, the number of exhaust holes 14 is several, and the several exhaust holes 14 are linearly arranged from left to right.

[0030] Working principle: When the utility model is used, the cooling fan 6 is first started, and the cooling fan 6 rotates to cool the transformer body 4. When the cooling fan 6 is running, the external cold air is drawn into the connecting frame 7 through the air inlet pipe 8, and the cold air enters the first installation frame 5 from the connecting frame 7, and finally enters the installation box 3, and the cold air is sprayed onto the transformer body 4, so that the cold air cools the transformer body 4 by air. At the same time, the cooled cold air becomes hot and flows upward, and the hot air is drawn out by the exhaust fan 10, and the hot air is guided to move upward, and the hot air is discharged into the exhaust frame 13 through the air collecting hood 12 and the exhaust pipe 11, and the hot air is discharged through the exhaust hole 14. When the cold air enters and is drawn into the installation box 3, since the air inlet of the air inlet pipe 8 is set downward, it can effectively prevent rainwater from being drawn into the installation box 3. At the same time, when the hot air is discharged Since the exhaust hole 14 is arranged downward, rainwater can be prevented from entering the exhaust frame 13 from the exhaust hole 14, and rainwater can be prevented from entering the installation box 3, and the transformer body 4 can be prevented from being damaged by rainwater. The first door panel 21 and the second door panel 22 can improve the rainproof effect of the installation box 3, prevent rainwater from entering the interior of the installation box 3, and further improve the rainproof effect of the installation box 3. When the device vibrates, the installation box 3 will drop. When the installation box 3 drops, it will push the support plate 17 to rotate the support plate 17. The lower end of the support plate 17 pushes the connecting block 16 to move, so that the connecting blocks 16 on the left and right sides move toward the two ends of the support rod 15 respectively. The connecting block 16 squeezes the spring 18, and the spring 18 is squeezed and shrinks, thereby buffering and shock absorbing the installation box 3, ensuring the stability and safety of the installation box 3, and improving the service life of the installation box 3.

[0031] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
