Phase change medium-based condenser device for evaporative cooling power transformer

The invention discloses a phase change medium-based condenser device for an evaporative cooling power transformer. The box body of the evaporative cooling power transformer is filled with a liquid insulating cooling medium with a phase change characteristic. The condenser device is communicated with the box body; the condenser device comprises a liquid storage tank, a liquid incoming pipeline, a liquid outgoing pipeline, a radiator and a pressure damper; the liquid storage tank comprises a liquid storage space capable of accommodating the liquid insulating cooling medium with the phase changecharacteristic and a steam space which is positioned above the liquid storage space and is used for heating the insulating cooling medium to expand so as to form steam; the liquid incoming pipeline and the liquid outgoing pipeline are communicated with the box body with the liquid storage space; the radiator is communicated with the steam space and is used for condensing the steam to form condensate and enabling the conde
