Description

Technical Field

[0001] The utility model relates to the technical field of electronic product transformers, in particular to a highly durable power transformer. Background Art

[0002] In order for electronic products to operate normally, electronic transformers are usually installed. They are electronic devices that convert the alternating voltage of the mains into direct current and then output a high-frequency alternating voltage through semiconductor switching devices, electronic components and high-frequency transformer windings. They are also an AC-DC-AC inverter circuit described in electronics theory. In simple terms, it is mainly composed of a high-frequency transformer core (iron core) and two or more coils, which do not change their positions. From one or more electrical circuits, AC power is converted into AC voltage and current through electromagnetic induction. At the output end of the high-frequency transformer, high-frequency AC or DC power of different voltage levels is supplied to one or more power circuits.

[0003] The structure of conventional electronic transformers is relatively fixed and is spatially connected with other electronic components. Once an electronic transformer fails, short-circuits, or even generates a high-voltage arc, it will damage other surrounding components at the same time, causing the entire device to be unable to be used normally, thereby increasing the maintenance cost of electronic products.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-durability power transformer is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a high-durability power transformer to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a highly durable power transformer, comprising a mounting seat group and an outer box assembly, a transformer body is arranged at the top center of the mounting seat group, and protective frame groups are arranged on the upper and lower sides of the transformer body, and arc extinguishing protection frames are arranged on the left and right sides of the transformer body, and a lifting frame group is vertically arranged on the side of the arc extinguishing protection frame away from the transformer body, the outer box assembly is connected to the power output end of the lifting frame group, the outer box assembly comprises a protective box, buckles, ventilation mesh ports and docking blocks, buckles are symmetrically arranged on the left and right sides of the bottom of the protective box, and ventilation mesh ports are arranged on the outer surface of the protective box, and a docking block is arranged on the inner top of the protective box.

[0007] Furthermore, the mounting seat group includes a base, a sealing strip, a movable shaft frame and a fixed block, the edge of the base is provided with a sealing strip, and a movable shaft frame is provided on the side of the sealing strip away from the base, and the top of the movable shaft frame is connected to a fixed block.

[0008] Furthermore, the mounting base group further includes fixing bolts and pins. Fixing bolts are vertically and threadedly installed on both the left and right sides of the base, and pins are arranged at equal intervals on the bottom of the base. The surface structure of the bottom edge of the protective box matches the surface structure of the side edge of the base, and the sealing strip is fixedly connected to the base.

[0009] Furthermore, the protective frame group includes a strengthening frame, a heat conduction plate, and buffer blocks. A heat conduction plate is provided on one side of the strengthening frame close to the transformer body, and buffer blocks are symmetrically arranged on the left and right sides of the strengthening frame away from the heat conduction plate.

[0010] Furthermore, one side of the heat conduction plate away from the strengthening frame is attached to one end surface of the transformer body, and one end of the arc extinguishing protection frame is connected to the strengthening frame and is arranged in a "囗" - shaped structure with the strengthening frame.

[0011] Furthermore, the lifting frame group includes a support frame, a guide rail, and a slider. A guide rail is installed on one side of the support frame away from the arc extinguishing protection frame, and a slider is slidably installed on the surface of the guide rail.

[0012] Furthermore, one side of the slider away from the guide rail is connected to the inner wall of the protective box, and the support frames are vertically symmetrically installed on both the left and right sides of the base.

[0013] Furthermore, the surface structure of the fixed block matches the surface structure of the buckle, and the surface structure of the docking block matches the surface structure of the top end of the support frame.

[0014] The utility model provides a highly durable power transformer, which has the following beneficial effects:

[0015] 1. In the utility model, when the outer box assembly is docked with the mounting base group through the operation of the structure of the lifting frame group, at this time, the protective box will be docked with the base. The sealing strip is at the edge of the docking part between the protective box and the base, which can effectively avoid the problem of liquid ingress. After the protective box is docked with the base, under the rotation of the movable shaft frame, the fixed block at its top will swing left and right in the vertical direction and be docked with the buckle, thereby connecting and fixing the mounting base group and the outer box assembly, further ensuring the closure of the structure between the two. At the same time, the ventilation mesh openings provided on the outer surface of the protective box can effectively ensure the ventilation effect between the inside and the outside, so as to avoid the abnormal operation of the transformer body due to heat accumulation during operation. By using the above - mentioned structure, it can not only provide external structural protection for the whole device, but also make it have good structural mobility for easy equipment maintenance. At the same time, it can ensure that the internal transformer body has good durability, and effectively isolate the internal transformer body from other components to avoid the expansion of damage when faults occur to each other.

[0016] 2. The utility model connects the slider to the inner wall of the protective box. Therefore, when the slider is in operation, the entire outer box assembly can move up and down in the vertical direction along the surface of the guide rail, thereby realizing the rapid separation or docking of the mounting seat group and the outer box assembly to ensure the flexibility of the structural parts. In addition, since a docking block is provided at the top of the inner part of the protective box, when the mounting seat group and the outer box assembly structure are docked and closed, the top of the support frame will be inserted into the inside of the docking block, and at the same time, the reinforcing frame at the top of the transformer body and the buffer block on one side will be against the top of the inner wall of the protective box. By using the above structure, effective structural support can be provided in the vertical direction, and the arc extinguishing protection frames provided on the left and right sides of the transformer body are used to limit the arc and help extinguish the arc, thereby ensuring the safety and stability of the operation of the entire transformer body to the greatest extent, preventing the arc from damaging the internal and external structures, and also avoiding the arc from damaging other external electronic components, thereby reducing the risk of damage as much as possible. At the same time, the arc extinguishing protection frame cooperates with the structural setting of the lifting frame group, which can provide structural support in the vertical direction while providing a certain degree of buffer protection in the horizontal direction, so as to ensure the service life and durability of the transformer body.

The mounting seat group 1 includes a base 101, a sealing strip 102, a movable shaft frame 103 and a fixed block 104. The edge of the base 101 is provided with a sealing strip 102, and a movable shaft frame 103 is arranged on the side of the sealing strip 102 away from the base 101, and the top of the movable shaft frame 103 is connected to the fixed block 104. The mounting seat group 1 also includes a fixed The fixing bolts 105 and the pins 106 are vertically threadedly installed on the left and right sides of the base 101, and the pins 106 are evenly arranged and installed at the bottom of the base 101. The bottom edge surface structure of the protective box 601 matches the side edge surface structure of the base 101, and the sealing strip 102 is fixedly connected to the base 101. The surface structure of the fixed block 104 matches the surface structure of the buckle 602, and the surface structure of the docking block 604 matches the top surface structure of the support frame 501. 5, when the outer box assembly 6 is structurally docked with the mounting seat assembly 1, the protective box 601 will be structurally docked with the base 101, and the sealing strip 102 is at the edge of the docking point between the protective box 601 and the base 101, which can effectively avoid the problem of liquid ingress. After the protective box 601 is docked with the base 101, under the rotation of the movable shaft frame 103, the fixed block 104 on the top thereof will swing left and right in the vertical direction and dock with the buckle 602, so as to connect and fix the mounting seat assembly 1 with the outer box assembly 6.
