[0023] The heat dissipation protection mechanism 3 includes a temperature sensor 301, a controller 302, a connecting plate 303, heat dissipation holes 304, a fixing plate 305, a connecting column 306, a fan 307, a connecting groove 308, and an exhaust hole 309. The temperature sensor 301 and the controller 302 are installed on the inner wall of the outer casing 1. The connecting plate 303 is located on the inner side wall of the outer casing 1. Heat dissipation holes 304 are formed on the outer wall of the connecting plate 303. The fixing plate 305 is located on the outer wall of the connecting plate 303. The connecting column 306 is installed on the upper wall of the fixing plate 305. The fan 307 is located on the outer wall of the connecting column 306. The connecting groove 308 is formed on the outer wall of the connecting plate 303. An exhaust hole 309 is formed on the side wall of the outer casing 1. The vent 309, through the arrangement of temperature sensor 301, controller 302, connecting plate 303, heat dissipation hole 304, fixing plate 305, connecting post 306, fan 307, connecting groove 308 and exhaust hole 309, when the transformer is in use, firstly, when the temperature inside the casing 1 rises, temperature sensor 301 senses that the temperature is higher than a preset threshold, then controller 302 will control the internal circuit switch to start fan 307. Fan 307 will draw air from inside the casing 1 and discharge it from heat dissipation hole 304 into connecting groove 308, and finally discharge it to the outside through exhaust hole 309, thereby controlling the temperature inside the casing 1 and protecting the transformer installed inside the casing 1.
[0024] Furthermore, the connecting plate 303 is symmetrically arranged with respect to the central axis of the outer casing 1, and the heat dissipation holes 304 are evenly distributed on one side surface of the connecting plate 303. The connecting plate 303 allows the fan 307 to be mounted on the outer wall of the connecting plate 303.
[0025] Furthermore, the fixing plates 305 are evenly distributed on one side surface of the connecting plate 303, and the fans 307 are evenly distributed on one side surface of the connecting plate 303. The fixing plates 305 can be used to connect the connecting columns 306 to them.

[0027] Furthermore, the waterproof component 4 includes a waterproof plate 401, a waterproof groove 402, a waterproof strip 403, a connecting plate 404, and a lock 405. The outer wall of the housing 1 is provided with the waterproof plate 401, and a waterproof groove 402 is formed on the outer wall of the housing 1.

When placed outdoors, the waterproof plate 401 can prevent rainwater from entering the housing 1 through the vent 309 when it rains. The height of the vent 309 is lower than that of the heat dissipation hole 304, so even if a small amount of rainwater enters the connecting groove 308, it cannot enter the housing 1. Then, the connecting plate 404 will abut against the waterproof strip 403 in the waterproof groove 402 to prevent rainwater from entering the housing 1 from the front.

[0030] Working principle: When using the transformer, firstly, when the temperature inside the casing 1 rises, the temperature sensor 301 senses that the temperature exceeds the preset threshold. Then, the controller 302 controls the internal circuit switch to start the fan 307. The fan 307 draws air from inside the casing 1 and discharges it through the heat dissipation hole 304 into the connecting groove 308, and finally discharges it to the outside through the exhaust hole 309, thereby controlling the temperature inside the casing 1 and protecting the transformer installed inside the casing 1. When the transformer is placed outdoors, when rainy weather arrives, the waterproof plate 401 can prevent rainwater from entering the casing 1 through the exhaust hole 309. Furthermore, the height of the exhaust hole 309 is lower than that of the heat dissipation hole 304, so even if a small amount of rainwater enters the connecting groove 308, it cannot enter the casing 1. Then, the connecting plate 404 will press against the waterproof strip 403 in the waterproof groove 402 to prevent rainwater from entering the casing 1 from the front. Finally, the lock 405 fixes the connecting plate 404 to the casing 1 to isolate rainwater and protect the transformer from rainwater corrosion.
