By adopting technique scheme, insulating oil flowline from transformer body under the effect of oil pump is inhaled into oil pipe, through being arranged on after the cooling fluid heat radiation in inner housing, through oil inlet pipe, flow back to the inside of transformer body, so periodic duty makes the insulating oil temperature of transformer body inside moderate in normal operating temperature range again.Due to not heat conduction of vacuum, utilize the vacuum heat-insulating layer forming between shell body and inner housing, reduce the interference that auxiliary radiating device is subject to external environment factor, under hot environment, still can keep original radiating effect, simultaneously, metallic support sheet can be delivered to shell body by the heat after heat radiation in inner housing again and dissipate, and prevents that heat from assembling in inner housing, and auxiliary radiating device loses radiating effect.
The utility model is further set to: described oil pipe comprises some straight tubes and some bend pipes, between two adjacent straight tubes, by bend pipe, joins end to end.
By adopting technique scheme, reasonably utilized the space of inner housing, lengthened the length of oil pipe in inner housing, the contact area of oil pipe and cooling fluid is increased, guarantee the radiating effect of oil circulation each time.
The utility model is further set to: described transformer body is provided with the control device for control oil pump start and stop, and the inside of transformer body comprises the thermocouple for detection of insulating oil temperature.
By adopting technique scheme, utilize thermocouple to detect the temperature of insulating oil, when the temperature of insulating oil reaches set point, thermocouple can pass to control device by temperature signal, control device just control oil pump starts, and insulating oil is sent into auxiliary radiating device heat radiation; When the temperature of insulating oil drops to set point, thermocouple just can be notified control device, and oil pump is quit work.
The utility model is further set to: described oil pipe is that aluminum alloy materials forms, described shell body coating solar heat reflection layer.
By adopting technique scheme, aluminium alloy density is low, and intensity is high, and plasticity is good, has good thermal conductivity and corrosion stability, industrial, is widely used, and the oil pipe radiating effect forming with aluminum alloy materials is remarkable; The enough usable reflection sun heat radiation of solar heat reflection layer, alleviates auxiliary radiating device and raises because solar light irradiation produces temperature, guarantees the radiating effect that auxiliary radiating device keeps under solar light irradiation, extends the useful life of transformer.
