Finally, the mounting base plate 1 is installed and fixed, and then the transformer body 2 is installed and fixed. When the transformer body 2 is vibrated, it is buffered by the first buffer spring 403, thereby ensuring the stability of the transformer body 2.

[0023] The four corners of the mounting base plate 1 are fixedly connected with mounting blocks 101, the bottom of the mounting base plate 1 is provided with a heat dissipation groove 102, and the top of the mounting base plate 1 and below the transformer body 2 are provided with a plurality of heat dissipation holes 103. The mounting base plate 1 is mounted and fixed by the mounting blocks 101, thereby mounting and fixing the transformer body 2. After the mounting base plate 1 is installed, air can flow in the heat dissipation groove 102, and a space is left between the bottom of the transformer body 2 and the mounting base plate 1, so that air can also flow. The heat dissipation groove 102 is connected with the space at this location through the heat dissipation holes 103, so that the heat at the bottom of the transformer body 2 can be quickly dissipated, thereby improving the heat dissipation effect of the transformer body 2.

[0024] Protective blocks 104 are fixedly connected at the four corners of the mounting base plate 1 and the top plate 3 and on the outside of the positioning rod 401, and buffer blocks 105 are fixedly connected to the outsides of multiple groups of protective blocks 104, and both ends of the multiple groups of buffer blocks 105 are fixedly connected to the protective blocks 104 through second buffer springs 106. When the transformer body 2 is installed on the inner side of the mounting base plate 1 and the top plate 3, the outer side of the transformer body 2 is protected by the multiple groups of protective blocks 104. At the same time, after the transformer body 2 is installed, the buffer blocks 105 cooperate with the second buffer springs 106 to buffer the collision and prevent the internal transformer body 2 from being affected by external forces.

Heat dissipation ducts 303 are opened on the left and right sides of the inside of the heat dissipation cover 301 and above the ventilation holes 202. When the transformer body 2 is working, the heat dissipation fan 302 inside the heat dissipation cover 301 is started, and the heat is exhausted by external exhaust to extract the heat, so as to extract the heat transferred from the transformer body 2 to the top plate 3. At the same time, when the heat dissipation fan 302 is working, the air is sucked in through the ventilation holes 202, then circulated in the heat dissipation duct 303 and finally discharged. Under the action of suction, the air can quickly circulate in the intervals between the heat dissipation fins 201, thereby further improving the external heat dissipation effect of the transformer body 2, thereby ensuring the safe operation of the transformer body 2.

[0027] The front and rear ends of the heat dissipation cover 301 are fixedly connected with a fixing plate 304, and the left and right ends of the fixing plate 304 are fixedly connected to the top plate 3 by screws. The heat dissipation cover 301 is installed on the top of the top plate 3 through the fixing plate 304, which is convenient for disassembly and maintenance.

[0028] A protective net 305 is fixedly installed on the top of the cooling fan 302, and a mounting cover 306 is fixedly connected to the outside of the cooling fan 302.

[0029] Implementation plan: align the hole in the connecting block 402 on the outside of the transformer body 2 with the positioning rod 401 and lower it until the receiving ring 404 supports the connecting block 402, thereby installing the transformer body 2 on the top of the mounting base plate 1, then align the hole on the top plate 3 with the top cover of the positioning rod 401, and then screw on the fixing cover 405 to install the transformer body 2 on the inner side of the mounting base plate 1 and the top plate 3 to protect the transformer body 2. The outer side of the transformer body 2 is protected by multiple sets of protective blocks 104. At the same time, after the transformer body 2 is installed, the buffer block 105 cooperates with the second buffer spring 106 to buffer the collision and prevent the internal transformer body 2 from being affected by external forces, thereby improving the safety of the transformer body 2. Finally, the mounting base plate 1 is installed and fixed, and then the transformer body 2 is installed and fixed. When the transformer body 2 is vibrated, it is buffered by the first buffer spring 403, thereby ensuring the stability of the transformer body 2. After the mounting base plate 1 is installed, the air can The heat dissipation groove 102 is connected with the space at the bottom of the transformer body 2 through the heat dissipation hole 103, so that the heat at the bottom of the transformer body 2 can be quickly dissipated. The multiple groups of heat dissipation fins 201 on the outside of the transformer body 2 can improve the external heat dissipation effect of the transformer body 2 itself. When the transformer body 2 is working, the heat dissipation fan 302 inside the heat dissipation cover 301 is started, and the heat dissipation is carried out by exhausting air externally to extract the heat from the transformer body 2 to the top plate 3. At the same time, when the heat dissipation fan 302 is working, the air is sucked in through the ventilation hole 202, then circulated in the heat dissipation duct 303 and finally discharged. Under the action of suction, the air can quickly circulate in the interval between the heat dissipation fins 201, which further improves the external heat dissipation effect of the transformer body 2. The whole operation process is simple and convenient, which can improve the overall stability and safety of the electronic transformer, improve the heat dissipation effect of the electronic transformer, and ensure the safe operation of the electronic transformer.
