Description

Technical Field

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

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is a basic equipment for power transmission and distribution and is widely used in industry, agriculture, transportation, urban communities and other fields. A single-phase transformer is a transformer with both primary and secondary windings being single-phase windings.

[0003] Chinese Patent Publication No. CN217902835U discloses a single-phase transformer, comprising a single-phase transformer body, a hanging ring, and a heat dissipation frame. The hanging ring is welded and fixedly mounted on the top surface of the single-phase transformer body, and the heat dissipation frame is provided on the outer surface of the single-phase transformer body. A fixing frame is installed at the center of the outer surface of the single-phase transformer body, and a positioning protrusion is provided on the bottom surface of the fixing frame. A straight plate is installed through the fixing frame, and a fixing plate is provided on the outer surface of the straight plate, and a through hole is opened on the fixing plate. A connecting strip is installed on the surface of the straight plate, and a sealing strip is provided on the top surface of the connecting strip, and the sealing strip is located below the heat dissipation frame.

[0004] In this existing design, although the sealing strip can be driven to rise by the connecting strip so that the sealing strip can slide into the heat dissipation frame for engagement and connection, thereby properly sealing the heat dissipation frame, thereby facilitating long-term storage of the single-phase transformer body as a whole and preventing foreign matter from entering the interior of the single-phase transformer body, the positions of the straight plate and the connecting strip can be positioned by engaging the through-holes on the fixing plate with the positioning protrusions, thereby facilitating the stability of the overall sealing. At the same time, the seal can be released by pressing down on the straight plate later, and the overall operation is convenient and quick. However, the heat dissipation frame is fixed and not easy to disassemble. When the heat dissipation requirements are different, it is not easy to increase or decrease the number and spacing of the heat dissipation slots according to the needs.

[0005] Therefore, a single-phase transformer is designed to solve the above problems. Utility Model Content

[0012] As a preferred embodiment of the single-phase transformer of the present invention, the baffle matches the shape and size of the heat dissipation slot, a magnet A is fixedly mounted inside the slider, and a magnet B is fixedly mounted on the surface of the slide rod.

[0013] As a preferred single-phase transformer of the present invention, the opposite sides of the magnet A and the magnet B are S pole and N pole respectively.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. In the utility model, a latch, a pull plate, a tension spring and a long block are provided. By pulling the pull plate, the latch is driven to move, and the latch is taken out from the inside of the heat dissipation frame. The heat dissipation frame is then released from the limit, and the heat dissipation frame can be removed by pulling it again, which is convenient for users to replace the heat dissipation frame in time according to actual heat dissipation needs to avoid affecting the use effect.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example

[0027] See also Figure 1-5The utility model provides a technical solution: a single-phase transformer, comprising a transformer body 1 and a heat dissipation frame 2, the heat dissipation frame 2 and the transformer body 1 are fixedly connected by a latch 4, and the fixing method is simple, and the latch 4 can be driven to move by pulling the pull plate 6, thereby releasing the limit of the heat dissipation frame 2, and then disassembling it, which improves the replacement efficiency. The heat dissipation frame 2 is located on the surface of the transformer body 1, and a long block 3 is fixedly installed on the surface of the transformer body 1. There are two groups of long blocks 3, and the two groups of long blocks 3 are diagonally distributed on the side of the heat dissipation frame 2, which is convenient for fixing the heat dissipation frame 2 to avoid shaking of the heat dissipation frame 2 during use and affecting normal use. A latch 4 is inserted on the surface of the long block 3, and a tension spring 5 is sleeved on the surface of the latch 4. One end of the tension spring 5 is fixedly connected to the surface of the transformer body 1, and the other end of the tension spring 5 is fixedly connected to the surface of the pull plate 6, so that the pull plate 6 can be automatically reset when the tension spring 5 is restored. , so that the pull plate 6 drives the latch 4 to fix the heat dissipation frame 2, one end of the latch 4 is fixedly installed with the pull plate 6, the surface of the heat dissipation frame 2 is provided with a groove 7, the inner wall of the groove 7 is fixedly installed with a slide bar 9, the surface of the slide bar 9 is slidably connected with a slider 10, and the side of the slider 10 is fixedly installed with a baffle 11, the baffle 11 and the shape and size of the heat dissipation groove 8 are matched, the interior of the slider 10 is fixedly installed with a magnet A12, and the surface of the slide bar 9 is fixedly installed with a magnet B13, which can block the heat dissipation groove 8 to prevent dust and other impurities from entering the interior of the transformer body 1 through the heat dissipation groove 8 due to long-term storage, thereby improving the protection effect. The opposite sides of the magnet A12 and the magnet B13 are S pole and N pole respectively. The slider 10 and the slide bar 9 can be fixed by the magnet A12 and the magnet B13, which makes it convenient to adjust the opening and closing of the heat dissipation groove 8 by the baffle 11. The surface of the groove 7 is provided with a heat dissipation groove 8.

[0028] Working principle: When replacing the heat dissipation frame 2, manually pull the pull plate 6 outward, the pull plate 6 drives the latch 4 to move outward, and at the same time the pull plate 6 pulls the tension spring 5 outward until the latch 4 is disengaged from the inside of the heat dissipation frame 2. At this time, pull another set of latches 4 to completely release the heat dissipation frame 2 from the limit, and remove the heat dissipation frame 2 from the surface of the transformer body 1. Then take a new heat dissipation frame 2, make the mounting holes on the surface of the heat dissipation frame 2 face the latch 4, and then release the hand pulling the pull plate 6. Since one end of the tension spring 5 is fixedly connected to the surface of the transformer body 1, and the other end of the tension spring 5 is fixedly connected to the surface of the pull plate 6, the tension spring 5 is lost when the pull plate 6 is released. Remove external force restrictions, and due to its own pulling force, the pull plate 6 is driven to move inward during the recovery process, and the pull plate 6 drives the pin 4 to move until the pin 4 passes through the mounting hole. At this time, the heat dissipation frame 2 can be fixed on the surface of the transformer body 1. When the transformer body 1 has not been used for a long time, manually slide the slider 10 downward to separate the magnet A12 from the magnet B13. At this time, the slider 10 can slide on the surface of the slide rod 9, and at the same time, the slider 10 drives the baffle 11 to move until the baffle 11 completely blocks the heat dissipation slot 8. At this time, the slider 10 just moves to the bottom end of the slide rod 9, and then the transformer body 1 can be placed.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields.
