Description

Technical Field

[0001] This utility model relates to the field of transformer frame technology, and more specifically to a vertical transformer frame structure. Background Technology

[0002] With the acceleration of industrialization and modernization, the demand for electricity in society is constantly increasing, and the amount of electricity used is growing explosively. This requires transformers in the power system to be able to withstand greater power and current, as well as higher reliability and efficiency. The vertical transformer skeleton structure has emerged to meet this need. The skeleton provides a clear path and space for the winding, making the winding process more orderly and precise. When manufacturing transformers, workers can wind the wires according to the shape and size of the skeleton, effectively reducing the probability of faults such as short circuits.

[0003] In existing vertical transformer frame structures, to effectively fix the magnetic core, it is usually necessary to wrap insulating tape around the outside of the magnetic core. From a practical point of view, when performing this wrapping operation, it is necessary to ensure that the insulating tape is evenly and tightly attached to the outside of the magnetic core to achieve the ideal fixing effect. However, although this method seems to put the magnetic core in a relatively stable state during initial installation, various complex factors can cause the magnetic core to gradually loosen during long-term use, which in turn causes the transformer to produce a whistling sound.

[0004] In addition, the existing vertical transformer frame structure has the disadvantage of low heat dissipation efficiency. When the temperature exceeds a certain limit, the performance of the insulation material inside the transformer will decrease, resulting in increased resistance, increased current loss, and thus reduced transformer efficiency.

[0005] To address the aforementioned problems, this application provides a vertical transformer frame structure. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vertical transformer frame structure to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a vertical transformer frame structure, including a frame assembly and a pin assembly installed below the frame assembly, a snap-fit ​​assembly is installed on the pin assembly, a positioning groove is provided on the frame assembly, a magnetic core assembly is provided on the outside of the frame assembly and the pin assembly, and a fixing assembly is installed on the magnetic core assembly;

[0008] Preferably, the skeleton assembly includes a winding drum, annular grooves, ventilation grooves, and connecting grooves. The winding drum has evenly distributed annular grooves and eight rows of ventilation grooves evenly distributed around its circumference. Eight connecting grooves connected to the ventilation grooves are formed between the upper and lower bottoms of the winding drum. Air flows through the connecting grooves between the annular grooves, effectively dissipating heat.

[0009] Preferably, the positioning groove includes a square snap-fit ​​groove and a cylindrical snap-fit ​​groove. The top of the winding drum has four square snap-fit ​​grooves and cylindrical snap-fit ​​grooves evenly distributed around its circumference. The cylindrical snap-fit ​​grooves are located at the top edge of the winding drum. At this time, the skeleton assembly and the pin assembly are removed as a whole, and the winding drum is limited by the square snap-fit ​​grooves and cylindrical snap-fit ​​grooves on the top of the winding drum to facilitate winding.

[0010] Preferably, the pin assembly includes a base, pin slots, inclined slots, and limiting blocks, wherein the base is fixedly installed at the bottom of the winding drum, the base has pin slots and inclined slots on its front and rear sides, and a pair of limiting blocks are fixedly installed on the base.

The snap-fit ​​block is slidably snapped into the inner cavity of the snap-fit ​​sleeve, and the positioning plastic part is fixedly installed on the snap-fit ​​block. The first spring is located on the left side of the snap-fit ​​point between the snap-fit ​​sleeve and the snap-fit ​​block. The snap-fit ​​assembly is distributed in a mirror image on both sides of the inclined groove opened on the front side of the base and is fixedly installed on the base. During the winding process, the main wire pin is snapped between the snap-fit ​​assembly. Under the action of the first spring pressing the snap-fit ​​block, it is limited by the two positioning plastic parts and the inclined groove opened on the front side of the winding cylinder.

[0012] Preferably, the magnetic core assembly includes an upper magnetic core and a lower magnetic core, wherein the upper magnetic core is attached above the lower magnetic core, the bottom of the lower magnetic core is engaged between two limiting blocks, and the cylindrical area between the lower magnetic core and the upper magnetic core is engaged inside the winding drum.

[0013] Preferably, the fixing assembly includes a first fixing block, a first fixing screw, a second spring, a slider, a first hinge, a second hinge, a connecting rod, a second fixing block, and a second fixing screw. The first fixing block is engaged with the side wall of the upper magnetic core. The threaded end of the first fixing screw passes through the first fixing block and engages with the magnetic core. The slider is slidably connected to the first fixing block. The second spring is fixedly installed at the engagement point between the slider and the first fixing block. The first hinge is fixedly installed on the first fixing block. The second hinges are fixedly installed in pairs on the lower magnetic core. The connecting rod is fixedly installed between the two second hinges at the end furthest from the lower magnetic core. The end of the first hinge furthest from the slider is rotatably sleeved onto the connecting rod. The second fixing block is fixedly installed... On the side of the second hinge away from the first hinge, the threaded end of the second fixing screw moves through the second fixing block and then threadedly engages with the lower magnetic core. After the winding is completed, the first fixing block is fixedly installed on the upper magnetic core by the first fixing screw. At this time, the second hinge is pushed upward, and the longer end of the second hinge is offset and rotated along the rotation axis of the second hinge until the second fixing block fixedly installed on the second hinge is in contact with the lower magnetic core. The second fixing screw is rotated to fix the second fixing block on the lower magnetic core. At this time, the first hinge engaged with the connecting rod is rotated to push the slider to move downward along the engagement point, and under the action of the second spring, it always gives the first fixing block a downward force so that the upper magnetic core fixedly connected to the first fixing block is always in close contact with the lower magnetic core.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] The fixing components ensure that the magnetic core remains in close contact after disassembly and assembly, effectively preventing the magnetic core from loosening during use and causing transformer whistling. At the same time, the ventilation slots and connecting slots in the frame assembly work together to effectively dissipate heat from the coils inside the frame, keeping them at the normal operating temperature and improving working efficiency.
