[0020] like Figure 1-Figure 3 As shown, a dry-type transformer that can avoid falling off includes a protective mechanism 1 and an exhaust mechanism 3. A diffuser mechanism 2 for discharging heat is installed in the middle of the surface of the protective mechanism 1, and the exhaust mechanism 3 for exhausting heat is arranged in the middle of the inner side of the diffuser mechanism 2, a transformer body 101, a lightning rod 102 and a grounding wire 103. A lightning rod 102 is installed on the upper side of the transformer body 101, and the bottom of the lightning rod 102 is connected to the grounding wire 103. Through the lightning rod 102, when the transformer body 101 is in an outdoor environment, lightning can be conducted into the ground through the grounding wire 103, thereby preventing the high-voltage current caused by lightning from damaging the transformer body 101, a cooling box 201, a shielding cover 202 and a dustproof net 203. The shielding cover 202 is fixed on the top of the cooling box 201, and the dustproof net 203 is arranged in the middle of the surface of the cooling box 201, a motor 301, a rotating shaft 302 and the first A blade wheel 303, the output end of the motor 301 is connected to the rotating shaft 302, and the first blade wheel 303, the tooth chain 304 and the second blade wheel 305 are fixed to the middle of the surface of the rotating shaft 302, the tooth chain 304 is connected to the upper and lower parts of the rotating shaft 302, and the second blade wheel 305 is provided above and below the tooth chain 304. The motor 301 can drive the rotating shaft 302 and the first blade wheel 303 to rotate, so that the heat generated when the transformer main body 101 is working can be discharged to the outside to prevent high temperature from affecting the operation of the entire transformer. At the same time, the first blade wheel 303 is long and can increase the exhaust area. The tooth chain 304 can be used to link the second blade wheel 305 to rotate in the same direction as the first blade wheel 303, thereby improving the heat dissipation efficiency. The dustproof net 203 and the shielding cover 202 can be used to block the exhaust to prevent external impurities, dust and rainwater from entering the cooling box 201;
[0021] like Figure 2-Figure 4As shown, a limiting mechanism 4 for preventing falling is provided on the top of the protective mechanism 1. The limiting mechanism 4 includes a wiring seat 401, a sliding groove 402, a sliding rod 403, a limiting plate 404, a spring 405 and a lead plug 406. A sliding groove 402 is provided on the upper part of the wiring seat 401, and a sliding rod 403 passes through the middle of the sliding groove 402. A limiting plate 404 is fixed to the top of the sliding rod 403, and a spring 405 is connected to one side of the surface of the limiting plate 404, and a lead plug 406 is provided on the other side of the limiting plate 404. The limiting plate 404 is elastically connected to the wiring seat 401 through the spring 405, and the sliding rod 403 is slidably connected to the wiring seat 401 through the sliding groove 402.
[0022] Through the limit plate 404 and the spring 405, the convex teeth on the surface of the limit plate 404 can perform one-way engagement restriction after the lead plug 406 is inserted, so that the lead plug 406 can lose the ability to be pulled outward after insertion. Through the sliding rod 403 with a rough outer surface, it can be moved upward along the terminal seat 401 and the sliding groove 402 with the help of external force, so that the engagement between the limit plate 404 and the lead plug 406 can be lost, and the lead plug 406 can be removed. In this way, when the limit plate 404 is engaged and limited, the firmness of the connection of the lead plug 406 can be improved to avoid falling off, thereby ensuring the safety of the transformer during operation.
[0023] Working principle: When using the transformer, first, through the limit plate 404 and the spring 405, the convex teeth on the surface of the limit plate 404 can perform one-way engagement restriction after the lead plug 406 is plugged in, so that the lead plug 406 can lose the ability to be pulled outward after being plugged in, and then through the sliding rod 403 with a rough outer surface, it can be moved upward along the terminal seat 401 and the sliding groove 402 with the help of external force, so that the limit plate 404 and the lead plug 406 can lose the ability to engage, and then the lead plug 406 can be taken out, and then through the lightning rod 102, when the transformer body 101 is in an outdoor environment, the lightning can be conducted into the ground through the grounding wire 103, from This can prevent the high voltage current caused by lightning from damaging the transformer main body 101. Subsequently, the motor 301 can drive the rotating shaft 302 and the first blade wheel 303 to rotate, so that the heat generated by the transformer main body 101 during operation can be discharged to the outside, avoiding high temperature affecting the operation of the entire transformer. At the same time, the first blade wheel 303 is long and can increase the exhaust area. Then, through the tooth chain 304, the second blade wheel 305 can be linked to rotate in the same direction as the first blade wheel 303, thereby improving the heat dissipation efficiency. Finally, the dustproof net 203 and the shielding cover 202 can be used to block the exhaust and prevent external impurities, dust and rainwater from entering the cooling box 201.
