The transformer device with good heat dissipation effect according to claim 1 , wherein a fixing frame ( 11 ) is fixedly connected to the center of the bottom of the rain shield ( 13 ), and the fixing frame ( 11 ) The bottom of the cooling fan (10) is fixedly connected to the top of the cooling fan (10), and the surfaces of the first hose (17) and the second hose (19) are screwed to the inner walls of the water inlet and outlet ends of the circulation pipe (33) respectively. 9. A transformer device with good heat dissipation effect according to claim 1, characterized in that: a controller is fixedly connected to the bottom of the left side of the inner cavity of the protective box (1), and the output ends of the controller are respectively connected to the high-pressure water pump (16), the input ends of the alarm light (8), the cooling fan (10) and the solenoid valve (14) are electrically connected in one direction through wires, and the output ends of the water level sensor (5) and the temperature sensor (32) are connected to the control The input terminals of the device are connected by electrical signals. 10. The method for using a transformer device with a good heat dissipation effect according to claim 1, characterized in that it comprises the following steps: A: Set the detection values of the temperature sensor (32) and the water level sensor (5), add an appropriate amount of water to the water collection tank (6), and then filter the impurities in the water through the filter screen (27) and enter the water collection tank (6). ), at the same time the rain shield (13) can collect rainwater and lead it into the water collecting tank (6), when the water level in the water collecting tank (6) reaches the detection value of the water level sensor (5), it will send a signal to the controller , through the controller to control the alarm light (8), and through the alarm light (8) to alarm, reminding to add water; B: The temperature of the inner cavity of the protective box (1) is detected by the temperature sensor (32). When the temperature reaches the detected value, it sends a signal to the controller, and the controller controls the cooling fan (10) and the high-pressure water pump (16) respectively. and the solenoid valve (14), which work through the cooling fan (10), blowing air to the transformer body (2) in the protective box (1), and quickly dissipate the internal heat through the ventilation hole (3); at the same time, the solenoid valve ( 14) Open, the water in the water collecting tank (6) flows from the first hose (17) into the circulation pipe (33) through the inclined pipe (7), and the circulation pipe (33) cooled by the water is connected to the transformer body (2). Surface contact and rapid cooling, so as to achieve heat dissipation effect; C: When the transformer body (2) needs to be repaired or inspected, open the box door (29), unscrew the first hose (17) and the second hose (19) from the circulation pipe (33), and then Pull out the fixing pin (22), and pull out the mounting plate (21) from the groove (24) of the fixing block (23), so that the transformer body (2) is taken out from the protective box (1) to facilitate maintenance. .
