Box-type transformer convenient for heat dissipation

The utility model discloses a box-type transformer convenient for heat dissipation, which relates to the field of transformers and comprises a box body, a fire extinguishing assembly is arranged in the box body and comprises a servo motor, a gas storage tank and an oxygen consumption cavity, the servo motor and the gas storage tank are positioned in the box body, and the oxygen consumption cavity is positioned at the lower part in the box body. According to the transformer anti-collision device, attention of a driver can be drawn through the reflective strips, the transformer can be avoided as much as possible, when collision occurs, after the anti-collision plates are stressed, the movable rods push the pressing plates to extrude the air bags, then the sliding blocks slide in the sliding grooves, meanwhile, the first springs and the second springs deform at the same time, and the anti-collision devices are arranged in the box body. The impact force can be reduced under buffering of the air bag, the first spr
