Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, specifically a low-noise transformer. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current (AC) voltage. It mainly consists of a primary coil, a secondary coil, and an iron core (or magnetic core). Its core function is to increase or decrease voltage, and it can also perform current transformation, impedance transformation, isolation, and voltage stabilization. The working principle of a transformer is based on the electromagnetic induction phenomenon of "electricity generating magnetism, and magnetism generating electricity." When AC current passes through the primary coil, an alternating magnetic field is generated in the iron core, which in turn induces an electromotive force in the secondary coil. By adjusting the turns ratio of the primary and secondary coils, voltage transformation can be achieved. Transformers are widely used in power system transmission and distribution processes, such as converting high-voltage electricity from power plants into low-voltage electricity suitable for household and industrial use. In addition, they are also used in industrial equipment, agricultural machinery, transportation, and urban communities.

[0003] Existing transformers often reduce noise by covering them with soundproof enclosures. However, these enclosed enclosures severely affect the transformer's heat dissipation performance and can easily damage the transformer. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a low-noise transformer, which effectively solves the problem that existing transformers often reduce noise by covering the outside of the transformer with a soundproof cover, but the closed soundproof cover seriously affects the heat dissipation performance of the transformer and is prone to damage to the transformer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-noise transformer, comprising a soundproof cover, a support base fixedly installed at the bottom of the soundproof cover, a protective shell fixedly installed on one side of the soundproof cover, a protective door hinged to the front of the soundproof cover, a drive motor fixedly installed inside the protective shell, a heat dissipation pipe fixedly installed in the middle of the rear side of the soundproof cover, and an air inlet pipe fixedly installed on the other side of the soundproof cover. A layer of sound-absorbing cotton is provided on the inner walls of the soundproof cover, the air inlet pipe, the heat dissipation pipe, and the inner side of the protective door. Dustproof nets are fixedly installed inside the bottom of the air inlet pipe and the heat dissipation pipe. Several noise-reducing blocks with sound-absorbing properties are fixedly installed on the top of the two dustproof nets. A cooling fan is provided inside the upper end of the heat dissipation pipe, and an air intake fan is provided inside the upper end of the air inlet pipe. A transmission assembly is provided at the output end of the drive motor, and the transmission assembly is connected to the cooling fan and the air intake fan. When the drive motor operates, it outputs power to the cooling fan and the air intake fan through the transmission assembly, causing the cooling fan to rotate to dissipate heat and the air intake fan to rotate to draw in air. The transformer body is fixedly installed at the inner bottom of the soundproof cover.

[0006] Preferably, the transmission assembly includes a rotating rod, which is fixedly installed at the output end of the drive motor. One end of the rotating rod passes through the soundproof cover and extends into the interior of the air intake pipe, where a rotating shaft is fixedly installed. A bearing is rotatably installed on the surface of the rotating shaft, and the surface of the bearing is fixedly connected to the interior of the air intake pipe through three second support rods. The end of the rotating shaft away from the rotating rod is fixedly connected to the intake fan.

[0007] Preferably, two rotating sleeves are rotatably mounted on the surface of the rotating rod, and a fixed rod is fixedly mounted on the surface of each of the two rotating sleeves. One end of each of the two fixed rods is fixedly connected to the inside of the soundproof cover.

[0008] Preferably, a driving bevel gear is fixedly installed in the middle of the surface of the rotating rod, a driven bevel gear is meshed with one side of the surface of the driving bevel gear, a shaft is fixedly installed on one side of the driven bevel gear, a bushing is rotatably installed on the surface of the shaft, the surface of the bushing is fixedly connected to the inside of the heat dissipation pipe through three first support rods, and the end of the shaft away from the driven bevel gear is fixedly connected to the cooling fan.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator starts the drive motor to drive the rotating rod to rotate inside the two rotating sleeves. When the rotating rod rotates, it drives the rotating shaft to rotate inside the bearing. When the rotating shaft rotates, it drives the air intake fan to rotate, thereby drawing external air into the soundproof cover through the air intake pipe. At the same time, the dustproof net can prevent external dust from entering. When the rotating rod rotates, it drives the driven bevel gear to rotate through the active bevel gear.

[0010] When the driven bevel gear rotates, it drives the shaft to rotate inside the bushing. The rotation of the shaft drives the cooling fan to rotate, and the cooling fan dissipates the heat inside the soundproof cover through the heat dissipation pipe. At the same time, noise reduction is achieved through the sound-absorbing cotton on the inner walls of the soundproof cover, air inlet pipe, and heat dissipation pipe, as well as the inner side of the protective door. Furthermore, several noise-absorbing blocks on two dustproof nets further enhance sound absorption and noise reduction, thereby greatly improving the noise reduction effect. This allows the transformer to maintain its noise reduction capability while also possessing excellent heat dissipation performance, thus extending the transformer's service life.
