Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a noise-reducing dry-type transformer. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. A dry-type transformer is a type of transformer. Dry-type transformers are often used in high-rise residential areas, office buildings, and hospitals. However, traditional dry-type transformers generate a lot of noise during use, which has a certain impact on the lives of people in the surrounding area.

[0003] Patent CN119786223A discloses a novel noise-reducing dry-type transformer. The dry-type transformer includes a base plate, a protective frame fixedly connected to the top edge of the base plate, two inspection doors on one side of the protective frame, rubber pads fixedly connected to the top of the base plate near the four corners inside the protective frame, and the same dry-type transformer fixedly connected to the top of the four rubber pads. A rectangular frame is fixedly connected to the top of the outer wall of the base plate, and the rectangular frame is connected to the base plate. A rectangular hole is opened at the top of the rectangular frame, and two side holes are opened on both sides of the rectangular frame. A first T-shaped block is slidably connected to both ends of the two side holes at the top. This patent achieves an effective improvement in the active heat dissipation efficiency of the dry-type transformer without affecting its natural heat dissipation and noise reduction function, achieving an optimized balance between noise reduction and heat dissipation performance, thereby improving the overall operational stability and reliability of the dry-type transformer. However, it suffers from the problem that transformer vibration does not completely reduce noise. Therefore, a noise-reducing dry-type transformer is proposed to solve the aforementioned problems.

The connection is made so that the circumferential surface of the connecting line 308 contacts the circumferential surface of the fixed rod 307. The rotating column 302 is connected to the reciprocating lead screw 1 303 and reciprocating lead screw 2 304 via a pulley set. The anti-theft device 4 includes a Z-shaped plate 401, a pressing wheel 402, a triangular prism 403, a sliding plate 404, a pressing block 405, a large spring 406, a door bolt 407, a limiting plate 408, and a door bolt block 409. The sliding plate 404 is fixedly connected to the rear of the transformer door 11, the door bolt block 409 is fixedly connected to the rear of the transformer door 11, the Z-shaped plate 401 is fixedly connected to the front of the irregular plate 305, the pressing block 405 is slidably connected to the bottom of the sliding plate 404, the triangular prism 403 is fixedly connected to the rear of the sliding plate 404, and the limiting plate 408 is fixedly connected to the bottom of the sliding plate 404.A large spring 406 is fixedly connected to the left side of the limiting plate 408, an extrusion wheel 402 is fixedly connected to the top of the Z-shaped plate 401, and a bolt 407 is fixedly connected to the right side of the extrusion block 405. The reinforcing device 5 includes a short reciprocating screw 501, a door panel 502, and an L-shaped plate 503.

The two ends of the large spring 406 are fixedly connected to the left side of the limiting plate 408 and the right side of the extrusion block 405, respectively.

[0024] Working principle: When the housing 1 shakes, it compresses the spring 202, and at the same time, it causes the connecting block 205 to move inward and compress the horizontal spring 208, which can reduce the shaking amplitude of the housing 1 and thus achieve the effect of noise reduction. The dual-axis motor 301 drives the rotating column 302 to rotate. The rotating column 302 drives the reciprocating screw 1 303 and reciprocating screw 2 304 to rotate through the belt. The reciprocating screw 1 303 drives the irregular plate 305 to move downward. The irregular plate 305 drives the damping sound insulation felt 309 on the surface of the roller 1 310 to move downward, which can block the air outlet and prevent sound from spreading out. The downward movement of the irregular plate 305 drives the moving plate 306 to move downward. The downward movement of the moving plate 306 drives the damping sound insulation felt 309 on the surface of the roller 2 311 to move upward through the connecting line 308, which can block the air inlet 10 and prevent sound from being transmitted.

[0025] The upward movement of the irregular plate 305 causes the Z-shaped plate 401 to move upward. The Z-shaped plate 401 then causes the extrusion roller 402 to move upward. The extrusion roller 402 extrudes the triangular prism 403, causing it to move to the right. The triangular prism 403 then causes the extrusion block 405 to move to the right. The extrusion block 405 then causes the door bolt 407 to move to the right, simultaneously extruding the large spring 406. The door bolt 407 moves to the right and enters the door bolt block 409, preventing the transformer door 11 from being opened and thus preventing theft. The dual-axis motor 301 drives the short reciprocating screw 501 to rotate. The short reciprocating screw 501 then causes the L-shaped plate 503 to move downward. The L-shaped plate 503 then causes the door panel 502 to move downward, blocking the transformer door 11 and further enhancing its anti-theft effect.

[0026] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the fire extinguishing device 6 includes a small motor 601, a rotating rod 602, a first bevel gear 603, a second bevel gear 604, a third bevel gear 605, a fourth bevel gear 606, a telescopic plate 607, a fixed body 608, a threaded rod 609, a horizontal reciprocating screw 610, a push plate 611, and a dry powder box 612.

The rotating plate 703 is fixedly connected to the right side of the housing 1, and the switch 705 is fixedly connected to the right side of the housing 1. The horizontal plate 704 is movable on the circumferential surface of the vertical reciprocating screw 702, and the power-off block 706 is fixedly connected to the bottom of the horizontal plate 704. The surface of bevel gear 603 meshes with the surface of bevel gear 604, and the surface of bevel gear 605 meshes with the surface of bevel gear 606.

[0027] Working principle: The small motor 601 drives the rotating rod 602 to rotate, which in turn drives the bevel gear 3 605 to rotate. The bevel gear 3 605 drives the bevel gear 4 606 to rotate, which in turn drives the threaded rod 609 to rotate. The threaded rod 609 drives the fixed body 608 to move, which in turn drives the telescopic plate 607 to extend or retract, thereby opening the dry powder box 612 and allowing the dry powder inside to fall out, which can prevent fire. The rotating rod 602 drives the bevel gear 1 603 to rotate, which in turn drives the bevel gear 2 604 to rotate, which in turn drives the bevel gear 2 605 to rotate. 4. The horizontal reciprocating screw 610 is rotated, which drives the push plate 611 to move back and forth, which can push out the dry powder remaining in the dry powder box 612 to prevent the fire from getting bigger. The rotating rod 602 drives the belt group 701 to rotate, which drives the vertical reciprocating screw 702 to rotate. The vertical reciprocating screw 702 drives the horizontal plate 704 to move downward, which drives the power cut-off block 706 to move downward to close the switch 705. This allows for power cut-off after a fire occurs to prevent the fire from spreading further and ensures the safety of personnel.
