Water-cooled box-type substation

The invention relates to the technical field of box-type substations, in particular to a water-cooling box-type substation, and solves the problems that in the prior art, only a cooling fan is adopted for heat dissipation, so that the heat dissipation of a device is low, the temperature in the substation cannot be quickly reduced, and an internal circuit is short-circuited. A water-cooled box-type transformer substation comprises a transformer substation body, exhaust fans communicated with the interior of the transformer substation body are arranged on two side walls of the transformer substation body, cooling shells are arranged on the other two side walls of the transformer substation body, and the sides, away from the transformer substation body, of the cooling shells are communicated with an external shell. A detachably connected first filter plate is arranged on one side, far away from the transformer substation, of the outer shell; through holes communicated with the cooling shell are formed in the two
