Abstract
The utility model discloses a radiator structure of a phase-shifting rectifier dry transformer, which comprises a plurality of three-phase three-limb core limbs arranged in parallel, a plurality of high voltage and low voltage coils, a plurality of main insulations among the high voltage coils and low voltage coils, a plurality of insulated braces and upper and lower grips evenly axially distributed on the external peripheries of the main insulations, as well as a wind shield. The high voltage coils and the low voltage coils are sleeved on the core limbs and arranged coaxially from inside to outside in the order of high voltage-low voltage coils; the wind shield is arranged round the middle of the axial direction of the high voltage and low voltage coils at an effective height. As the wind shield is arranged round the middle of the axial direction of the high voltage and low voltage coils at a one third or two third height, the heat of the coils above the wind shield can be dissipated in a centralized manner through a fan arranged on the top of the box body. The utility model has the advantages of effectively improving the heat dissipation conditions of the transformer, and tremendously reducing the heat of the transformer with low cost and easy feasibility.
