The invention provides a substation system transformer intellectualized cooling system. The system comprises a transformer, a base for supporting the transformer and a frame platform arranged on the surrounding ground of the transformer, a circle of pressure pipelines are arranged at the portion, around the transformer, on the frame platform and are communicated with a water supply mechanism, a walking mechanism is arranged at the portion, corresponding to the pressure pipelines, on the frame platform, an atomizing spraying mechanism is arranged on the walking mechanism, several L-shaped connection pipelines are vertically arranged on the pressure pipelines, the atomizing spraying mechanism is matched with the connection pipelines, a temperature monitoring mechanism is arranged at the portion, corresponding to the transformer, on the pressure pipelines and is connected with a control mechanism, the control mechanism is connected with the walking mechanism and the atomizing spraying mechanism, a water collection tank is arranged below the frame platform, and a water storage layer is arranged in the water storage tank. By means of the substation system transformer intellectualized cooling system, the temperature of the transformer can be automatically detected, spraying and atomizing cooling can be conducted in a high-temperature area, the safety when the substation transformer is run is improved, and the stable supply of electric power is guaranteed.
