[0002] A transformer rectifier that facilitates later maintenance is a power conversion device whose structural design fully considers ease of maintenance. Through modular layout, quick disassembly and assembly structure, and accessibility design, it allows technicians to perform repairs and component replacements more efficiently when equipment malfunctions or needs maintenance. Currently, commonly used transformer rectifiers generally have a complex disassembly process during subsequent maintenance and repair. Therefore, there is a need for a new type of transformer rectifier that facilitates later maintenance. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a transformer rectifier that facilitates subsequent maintenance, thereby solving the problem that existing transformer rectifiers generally have complex disassembly processes during subsequent maintenance and repair.

[0004] This utility model provides a transformer-rectifier that facilitates later maintenance, achieved through the following specific technical means:

[0005] A transformer rectifier that facilitates later maintenance includes a chassis, a top cover, and a mounting bracket;

[0006] The chassis has grooves on its left and right sides, and three sets of threaded holes on the outer sides of its front and rear ends. The chassis has eight sets of round holes and two sets of exhaust holes on its rear side. The top cover is placed on the outer side of the upper end of the chassis, and the lower sides of the left and right ends of the top cover are movably locked into the grooves on the left and right sides of the chassis. The top cover has three sets of threaded holes on its front and rear ends, which correspond to the threaded holes on the outer sides of the front and rear ends of the chassis. The fixing frame is movably locked into the inner side of the rear end of the chassis. The fixing frame has eight sets of threaded holes on its rear side, which correspond to the eight sets of round holes on the rear side of the chassis. The fixing frame has two sets of round holes, which correspond to the two sets of exhaust holes on the rear side of the chassis.

[0007] Furthermore, a set of sealing strips is connected to the inner sides of the front and rear ends of the top cover.

[0008] Furthermore, the front side of the chassis is connected to a connector, and two sets of L-shaped connectors are provided on the connector. The two sets of L-shaped connectors are symmetrical. Wiring ports A and B are respectively installed on the left and right sides of the front end of the chassis. Indicator lights A and B are installed on the front side of the chassis.

[0009] Furthermore, the chassis has five sets of grooves inside, and a connecting frame is provided inside each of the five sets of grooves. The main transformer inductor bracket is movably connected inside the chassis.

[0010] Furthermore, a set of exhaust fans is installed inside each of the two sets of circular holes on the fixing frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting up a top cover, this utility model facilitates the upper cover to be movably and snapped into the grooves on the left and right sides of the chassis through the lower sides of the left and right ends. The three sets of threaded holes at the front and rear ends of the top cover correspond to the threaded holes on the outer sides of the front and rear ends of the chassis. The top cover is connected to the chassis by threaded bolts. When disassembling, the top cover can be easily removed by simply unscrewing the threaded bolts. This facilitates quick maintenance of core components such as the main transformer inductor support and connecting frame inside the chassis, reducing the difficulty of maintenance.

[0013] 2. This utility model features a chassis with wiring ports A and B installed on the left and right sides of the front end. By using wiring ports A and B, input lines and output lines, as well as high-voltage lines and low-voltage lines, can be connected separately, avoiding wiring crossover and confusion, reducing the risk of wiring errors, and the partitioned layout facilitates quick location of line functions during later maintenance, thus improving maintenance efficiency.

[0014] 3. By setting up a main transformer inductor bracket, which is movably connected to the chassis, this utility model facilitates the independent disassembly and assembly of the main transformer inductor. When the main transformer inductor fails, maintenance personnel do not need to disassemble the entire internal wiring of the equipment. They can simply loosen the bracket connection to remove the inductor for inspection or replacement, which greatly shortens the maintenance time. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example:

[0025] As attached Figure 1 To be continued Figure 7 As shown:

[0026] This utility model provides a transformer rectifier that is easy to maintain in the later stage, including a chassis 1, a top cover 2, and a fixing frame 9;

[0027] The chassis 1 has grooves on its left and right sides, and three sets of threaded holes on the outer sides of the front and rear ends of the chassis 1. The chassis 1 has eight sets of round holes on its rear side and two sets of exhaust holes on its rear side. The upper cover 2 is placed on the outer side of the upper end of the chassis 1, and the lower sides of the left and right ends of the upper cover 2 are movably locked into the grooves on the left and right sides of the chassis 1. The upper cover 2 has three sets of threaded holes on its front and rear ends, which correspond to the threaded holes on the outer sides of the front and rear ends of the chassis 1. The fixing frame 9 is movably locked into the inner side of the rear end of the chassis 1. The fixing frame 9 has eight sets of threaded holes on its rear side, which correspond to the eight sets of round holes on the rear side of the chassis 1. The fixing frame 9 has two sets of round holes, which correspond to the two sets of exhaust holes on the rear side of the chassis 1.

[0028] Among them, such as Figure 7 As shown, a set of sealing strips 13 are connected to the inner sides of the front and rear ends of the upper cover 2. When the upper cover 2 and the chassis 1 are fixed through the threaded holes, the sealing strips 13 will be squeezed and filled in the joint between the upper cover 2 and the chassis 1 to form a sealed space, which effectively prevents dust, water vapor, oil and other impurities from entering the equipment from the joint, avoids problems such as short circuits and component corrosion caused by the accumulation of impurities, and extends the service life of the transformer rectifier.

[0029] Among them, such as Figure 2As shown, a connector 3 is connected to the front of the chassis 1, and two sets of L-shaped connectors 11 are provided on the connector 3. The two sets of L-shaped connectors 11 are symmetrical. Wiring ports A4 and B5 are installed on the left and right sides of the front of the chassis 1, respectively. Indicator lights A6 and B7 are installed on the front of the chassis 1. By setting wiring ports A4 and B5 on the left and right sides, the input lines and output lines, high-voltage lines and low-voltage lines can be connected separately to avoid the confusion of the lines and reduce the risk of wiring errors. The partitioned layout makes it easy to quickly locate the line function during later maintenance and improves maintenance efficiency. Indicator lights A6 and B7 can be used to correspond to different functional states.

[0030] Among them, such as Figure 2 As shown, the chassis 1 has five sets of grooves inside, and each of the five sets of grooves has a connecting frame 8. The main transformer inductor bracket 10 is movably connected inside the chassis 1. Through the five sets of connecting frames 8, an independent modular installation unit is formed. The connecting frame 8 can be used to fix core components such as transformers, rectifier modules, and capacitors. The shape and size of the grooves are precisely matched with the connecting frame to ensure accurate positioning of components during installation and avoid poor line contact or mechanical stress concentration caused by installation deviation. The movable connection between the main transformer inductor bracket 10 and the inside of the chassis means that the main transformer inductor can be independently disassembled and installed. When the main transformer inductor fails, maintenance personnel do not need to disassemble the entire internal wiring of the equipment. They only need to loosen the bracket connection to remove the inductor for inspection or replacement, which greatly shortens the maintenance time.

[0031] Among them, such as Figure 2 and Figure 4 As shown, a set of exhaust fans 12 are installed inside the two sets of round holes on the mounting bracket 9. Multiple sets of ventilation holes are provided on the front side of the chassis 1. By using the ventilation holes on the front side of the chassis 1 in conjunction with the exhaust holes on the rear side of the chassis 1, it is beneficial to form a through-type heat dissipation channel when the exhaust fans 12 draw air outward, thus avoiding local heat accumulation.

[0032] The specific usage and function of this embodiment are as follows:

[0033] like Figures 1 to 7 As shown, in this utility model, when the upper cover 2 and the chassis 1 are fixed through the threaded hole, the sealing strip 13 will be squeezed and filled at the joint between the upper cover 2 and the chassis 1 to form a sealed space, effectively preventing dust, water vapor, oil and other impurities from entering the equipment from the joint, avoiding problems such as short circuits and component corrosion caused by the accumulation of impurities, and extending the service life of the transformer rectifier. By setting the wiring ports A4 and B5 on the left and right sides respectively, the input line and output line, high voltage line and low voltage line can be connected in separate sections to avoid the line crossing and confusion, reduce the risk of wiring errors, and the partitioned layout facilitates quick location of line functions during later maintenance, improving maintenance efficiency. The indicator lights A6 and B7 can be used to correspond to different functional states respectively.

[0034] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
