Transformer box

The invention discloses a transformer box. The transformer box comprises a box body, a water tank, a water pipe and a water pump; a cavity is formed in the box body, an air channel is formed between the cavity and the outer side face of the box body, and first air ports are formed in the two opposite outer side faces of the box body respectively; the water tank is arranged on the top of the box body, the water pipe is arranged in the air channel and disposed around the cavity, the two ends of the water pipe are communicated with the water tank separately, and the water pump is arranged in thewater tank and used for driving water in the water pipe to flow circularly. The transformer box solves the problems that a transformer box in the prior art is monotonous in function and poor in sealing and heat dissipation performance, a large amount of heat can be generated in long-time operation of a transformer and affects the normal operation of the transformer, and a too low temperature alsoaffects the normal operati
