Description
Technical Field
[0001] The invention belongs to the technical field of dry-type transformers, and in particular relates to a noise-reducing dry-type transformer. Background Art
[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. Dry-type transformers are mainly composed of cores composed of silicon steel sheets and coils cast with epoxy resin. Insulating cylinders are placed between high-voltage and low-voltage coils to increase electrical insulation, and the coils are supported and constrained by pads. The fasteners of the overlapping parts have loose performance; existing dry-type transformers will generate greater noise when in use. Since dry-type transformers are often used in high-rise residential areas, office buildings, hospitals and other places, they have a certain impact on the lives of people around them.
[0003] However, when the existing dry-type transformer is in use, the heat it generates is often dissipated to the outside through the heat dissipation holes, which makes it easy for dust to be generated at the heat dissipation holes when placed for a long time. At this time, when receiving heat, it is easy for the dust in the heat dissipation holes to be lifted up and enter the dry-type transformer, causing damage to the dry-type transformer.

[0047] Embodiment 3:
[0048] The difference between Example 2 and this example is as follows: Figures 2 to 8 As shown, a noise reduction dry-type transformer, two collection boxes 3011 are fixedly connected with a positioning plate 3024 at one end away from the tilting block 3012, and the two positioning plates 3024 are symmetrical to each other.

[0049] The implementation principle of a noise reduction dry-type transformer of the present invention is as follows:
[0050] First, when the staff uses the transformer body 104, by starting the servo motor 201, the rotating rod 2011 can be driven to rotate. When the rotating rod 2011 rotates, it can make the guide sleeve 2014 reciprocate vertically with the assistance of the guide slot 2012, the guide slider 2013, the connecting rod 2015 and the moving plate 202. When the guide sleeve 2014 reciprocates vertically, it can drive the connecting rod 2015 and the moving plate 202 to reciprocate vertically.
[0051] When the movable plate 202 moves, it can push the wedge block 2021 to move, and when the wedge block 2021 can drive the placement plate 2022 and the guide rod 2023 to move with the assistance of the moving slide groove 203 and the moving slider 2031, when the placement plate 2022 drives the guide rod 2023 to move, the guide rod 2023 can clean the heat dissipation holes 1012 opened on the side wall of the protective shell 101, thereby ensuring that the heat dissipation holes 1012 will not be blocked (and when the movable plate 202 is reset, the wedge block 2021, the placement plate 2022 and the guide rod 2023 can be assisted by the elastic force of the reset spring 2032, so that the moving slider 2031 can be reset with the assistance of the moving slide groove 203, and when the moving slider 2031 is reset, it can drive the wedge block 2021, the placement plate 2022 and the guide rod 2023 to reset);
[0052] At the same time, when the placing plate 2022 moves, it can also drive the L-shaped rod 301 to move. When the L-shaped rod 301 moves, it can drive the collecting box 3011 to move horizontally. When the collecting box 3011 moves, it can push the flip plate 302 to open with the assistance of the rotating rod 3021. When the flip plate 302 is opened, the collecting box 3011 continues to move outward, which can allow the flip plate 302 to be located at the collecting position with the assistance of the positioning plate 3024. The dust in the heat dissipation hole 1012 opened at the protective shell 101 can be cleaned by the guide rod 2023, and then the dust can fall onto the flip plate 302, and then enter the collection box 3011 along the flip plate 302, so that the dust can be collected. Therefore, to a certain extent, it is avoided that the dust is lifted up by external force, which causes some dust to enter the heat dissipation hole 1012 again.
