As shown in fig. 2, the water flooding detection system 4 includes a float 41, a detection circuit 42 connected to the float 41, and a detection module 43 connected to the detection circuit 42. Wherein, the floater 41 is arranged on the side wall of the bottom of the box body, the arrangement height of the floater 41 is determined according to the geographical position environment at the time, the float 41 is moved when the accumulated water reaches the float 41, a relay 421 connected to the float 41 is included in the detection circuit 42, the float 41 is moved when the accumulated water overflows the position of the float 41, further, the relay 421 is driven to close, so that the detection circuit 42 is turned on to output a high level signal, the detection module 43 detects the high level signal and outputs the water level information at this time, if the output state is the water immersion state to the main control unit 8, the main control unit 8 receives the water level information, the starting motor works to drive the first movable cover plate to horizontally slide to seal the hollow area 11 at the bottom of the box body, so that accumulated water is prevented from entering the box body from the hollow area 11, make circuit or cable in the box wet or meet water, and then make the transformer unable work.

According to the box-type transformer provided by the invention, the proper temperature range for the cable to work and the corresponding control instruction are preset by a computer program, so that the proper working temperature of the cable can be ensured to be in the proper range. For example, when the ambient temperature is lower than a certain temperature (e.g., 10 degrees celsius), the main control unit 8 starts the low-temperature environment adaptive function. For example, the cable is operated at a suitable temperature of 30 ℃, and when the temperature in the low-voltage cabinet is lower than 28 ℃, the motor pushes the first motorized cover plate on the bottom hollowed-out area to close the hollowed-out area, so that cold air is prevented from entering the box-type transformer, and the second motorized cover plate at the air outlet is closed. After the above actions are carried out for a certain time (such as 5 minutes), if the temperature is not up to 30 ℃, the heating device in the cabinet body is started to heat the air.

When the main control unit detects that the temperature of the cable in the transformer is higher than a certain temperature (for example, 95 degrees), the cable cooling function, that is, the semiconductor cooling device needs to be started.

Wherein, under the condition that there is ponding bottom the cabinet body in rainy day, when the master control unit detected the state information that soaks, then starter motor drove first movable cover plate and seals the fretwork region, prevents that water from getting into the cabinet body, leads to the cabinet body can not work.
