Description

Technical Field

[0001] The invention relates to the technical field of electric power, in particular to an energy-saving and noise-reducing transformer. Background Art

[0002] From the late 9th century to the early 20th century, transformers were gradually used in power systems. During this period, the design and manufacture of transformers mainly relied on experience, and the material properties and manufacturing processes were relatively backward, resulting in large transformers, high losses, and low efficiency.

[0003] In the 1940s, with the development of materials science and manufacturing technology, transformer technology made a major breakthrough. The application of high-performance materials such as silicon steel sheets and aluminum alloys has reduced the size of transformers, reduced losses, and improved efficiency. At the beginning of the 21st century, with the development of computer technology, communication technology, and Internet of Things technology, transformers began to move towards intelligence. Intelligent transformers integrate sensors, controllers, communication modules, etc., and can realize functions such as remote monitoring, fault diagnosis, and automatic adjustment. Transformers can be divided into many types according to their structure, purpose, and performance, such as oil-immersed transformers, dry-type transformers, and amorphous alloy transformers. Among them, oil-immersed transformers use transformer oil as an insulating medium and cooling medium, and have excellent insulation and heat dissipation properties; dry-type transformers use epoxy resin materials to cast iron cores and coils, which have the advantages of simple structure and easy maintenance; amorphous alloy transformers use amorphous alloy materials as magnetic circuit materials, which have the characteristics of good temperature resistance and high energy efficiency. In terms of application areas, transformers are widely used in power systems, industrial fields, urban construction, and other aspects. In the power system, transformers play a vital role, including power generation, transmission, transformation, and distribution. In the industrial field, transformers are widely used in steel, petroleum, chemical, papermaking and other industries. In urban construction, transformers are also widely used in subways, light rails, high-rise buildings and other fields.

[0004] When the transformer is working, noise will be generated due to the magnetostrictive vibration of the iron core, the electromagnetic vibration of the coil, the cooling system and the flow of transformer oil. Summary of the invention

[0005] The invention aims to solve the technical problem of how to reduce the noise of the transformer, and the energy-saving noise-reducing transformer proposed, the technical solution of the invention is as follows: The energy-saving noise reduction transformer comprises: a box, an automatic noise reduction device, a ventilation device, a dust prevention device, and a controller.

A plurality of second ventilation holes are respectively arranged on the two noise reduction plates, and cooperate with a plurality of the first ventilation holes.

[0007] When the noise detector detects that the transformer noise reaches a set value, the controller controls the first electric push rod and the second electric push rod to extend to drive the first noise reduction plate and the second noise reduction plate to move upward, so that the first heat dissipation hole and the second heat dissipation hole are staggered, thereby achieving a noise reduction effect.

[0008] When the noise detector detects that the transformer noise is lower than the set value, the controller controls the first electric push rod and the second electric push rod to shorten and drive the first noise reduction plate and the second noise reduction plate to move downward, so that the first heat dissipation hole and the second heat dissipation hole are connected, thereby achieving ventilation.

[0009] Furthermore, the first noise reduction plate and the second noise reduction plate are made of polyester fiber.

[0010] The fiber structure inside the polyester fiber sound insulation board is dense and uniform, with good damping performance and sound energy conversion ability.

The four sliding blocks 407 are respectively fixedly connected to the two scrapers 406 and slidably connected to the two filter plates 402, and their sliding directions are perpendicular to the first noise reduction plate 205.

[0045] When the first noise reduction plate 205 and the second noise reduction plate 207 move upward, the first noise reduction plate 205 and the second noise reduction plate 207 drive the second connecting rod 403 to move upward, the second connecting rod 403 drives the third connecting rod 405 to move, and the movement of the third connecting rod 405 drives the scraper 406 and the sliding block 407 to move toward the direction close to the bracket 404, thereby cleaning up the debris and dust on the filter plate 402 to prevent the filter plate 402 from being blocked.

[0046] When the first noise reduction plate 205 and the second noise reduction plate 207 move downward, the first noise reduction plate 205 and the second noise reduction plate 207 drive the second connecting rod 403 to move downward, and the movement of the third connecting rod 405 drives the scraper 406 and the sliding block 407 to move away from the bracket 404, thereby cleaning up the debris and dust on the filter plate 402 to prevent the filter plate 402 from being blocked.

[0047] The dustproof device includes: a support column 501 and a dustproof plate 502. The support plate is vertically arranged above the box 101, and the lower end is fixedly connected to the outer top surface of the box 101. The dustproof plate 502 is V-shaped, arranged above the support column 501, and fixedly connected to the upper end of the support column 501.

[0048] The dustproof plate 502 can reduce the amount of debris that enters the box body 101 through the first wind cap 301, the second wind cap 304 and the dustproof box 401, and also plays a waterproof role.

[0049] The filter plate 402 is made of synthetic fiber.

[0050] Synthetic fiber material has high filtration efficiency and can effectively remove tiny particles in the fluid The support column 501 is fixedly connected to the dustproof plate 502 by welding.

[0051] The support column 501 is fixedly connected to the dustproof plate 502 by welding, which is convenient for workers to install.

[0052] Working principle: When the noise detector 208 detects that the noise of the transformer 203 reaches the set value, the controller 102 controls the first electric push rod 204 and the second electric push rod 206 to extend and drive the first noise reduction plate 205 and the second noise reduction plate to move upward, so that the first heat dissipation hole and the second heat dissipation hole are staggered, thereby achieving the effect of noise reduction. At the same time, the first noise reduction plate 205 drives the first connecting rod 311 to rotate, and the first noise reduction plate 205 and the second noise reduction plate 207 second connecting rod 403 move upward.

[0053] When the first connecting rod 311 rotates, the first connecting rod 311 pushes the sliding plate 310 to move toward the air outlet 309 until the air inlet 308 is not blocked. At this time, the air inlet 308 is unblocked, and driven by the first hood 301, the first hood 301 will drive the first rotating rod 302 to rotate, and the rotation of the first rotating rod 302 drives the forward fan 303 to rotate. Driven by the second hood 304, the second hood 304 will drive the second rotating rod 305 to rotate, and the rotation of the second rotating rod 305 drives the reverse fan 306 to rotate. The forward fan 303 sucks external cold air from the first hood 301 into the inside of the box 101, and the reverse fan 306 discharges the hot air inside the box 101 from the second hood 304, thereby preventing overheating inside the box 101 when the noise reduction of the transformer 203 body is performed.

[0054] When the second connecting rod 403 moves upward, the second connecting rod 403 drives the third connecting rod 405 to move, and the movement of the third connecting rod 405 drives the scraper 406 and the sliding block 407 to move toward the bracket 404, thereby cleaning up the debris and dust on the filter plate 402 to prevent the filter plate 402 from being blocked.

[0055] When the noise detector 208 detects that the noise of the transformer 203 is lower than the set value, the controller 102 controls the first electric push rod and the second electric push rod 206 to shorten and drive the first noise reduction plate 205 and the second noise reduction plate to move downward, so that the first heat dissipation hole and the second heat dissipation hole are connected, thereby achieving ventilation. At the same time, the first noise reduction plate 205 drives the first connecting rod 311 to rotate in the opposite direction, and the first noise reduction plate 205 and the second noise reduction plate 207 second connecting rod 403 move downward.

[0056] When the first connecting rod 311 rotates in the opposite direction, the first connecting rod 311 pulls the sliding plate 310 to move toward the air inlet 308 until the air inlet 308 is blocked, and the second hood 304 drives the second rotating rod 305 to rotate, and the rotation of the second rotating rod 305 drives the reverse fan 306 to rotate, thereby exhausting the hot air from the box body 101. With the cooperation of the first ventilation hole 209 and the second ventilation hole 210, an air duct is formed, and the cold air enters the box body 101 through the dustproof box 401, thereby dissipating the heat inside the box body 101.

[0057] When the second connecting rod 403 moves downward, the second connecting rod 403 drives the third connecting rod 405 to move, and the movement of the third connecting rod 405 drives the scraper 406 and the sliding block 407 to move away from the bracket 404, thereby cleaning up the debris and dust on the filter plate 402 to prevent the filter plate 402 from being blocked.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
