Embodiment
With reference to Fig. 1, a kind of heat abstractor being applied to dry-type transformer, comprise more than one for accelerating the blowing device 2 of transformer 1 surrounding air flowing, the motor 21 that this blowing device 2 comprises fan leaf 20 and drives described fan leaf 20 to rotate, here, described blowing device can adopt a motor 21 to drive the structure of one piece of fan leaf 20 rotation, the structure that simultaneously a motor 21 also can be adopted to drive polylith fan leaf 20 simultaneously to rotate, namely described blowing device 2 comprises a motor 21 and polylith is driven the fan leaf 20 simultaneously rotated by this motor 21; Also comprise more than one temperature difference electricity generation device 3, the hot junction of described temperature difference electricity generation device 3 contacts with transformer 1, and the electric energy output end of temperature difference electricity generation device 3 is then connected with described motor 21 simultaneously.In the utility model, the hot junction of described temperature difference electricity generation device 3 contacts with transformer 1, the cold junction of temperature difference electricity generation device 3 then can be exposed in air or close proximity to ground etc., when transformer 1 operationally causes its temperature to raise because transformer 1 constantly gathering heat, and then the temperature in hot junction that temperature difference electricity generation device 3 contacts with transformer 1 also constantly raises, cold junction due to temperature difference electricity generation device 3 is exposed to aerial or close proximity to ground etc., therefore there is the temperature difference in the hot junction of temperature difference electricity generation device 3 and cold junction, and then temperature difference electricity generation device 3 can generate electricity, electric energy is delivered to motor 21 place by the electric energy output end of temperature difference electricity generation device 3, when the cold junction of temperature difference electricity generation device 3 and the temperature difference in hot junction continue to increase, the voltage that temperature difference electricity generation device 3 exports also constantly increases until reach the rated operational voltage of motor 21, now motor 21 normally works with drive fan leaf 20 rotation blowing, accelerate transformer 1 ambient air flowing heat radiation.
When motor 21 task driven fan leaf 20 blowing heat radiation, transformer 1 ambient air can accelerate to circulate heat radiation, therefore the temperature of transformer 1 can decline, therefore the temperature in hot junction that temperature difference electricity generation device 3 is connected with transformer 1 is also declining, and then the temperature difference between the cold junction of temperature difference electricity generation device 3 and hot junction diminishes, so the voltage that temperature difference electricity generation device 3 produces can diminish gradually, when temperature difference electricity generation device 3 export voltage can not driven motor 21 work time, motor 21 is shut down, fan leaf 20 also no longer rotates blowing heat radiation, therefore transformer 1 ambient air no longer accelerates flowing heat radiation, thus the temperature of transformer 1 can raise again again, correspondingly, the temperature difference between the cold junction of temperature difference electricity generation device 3 and hot junction also can increase again, so the voltage that temperature difference electricity generation device 3 exports can become large again gradually until again can rotate and drive fan leaf 20 to rotate blowing heat radiation by drive motors 21, circulation like this is continuous, the start and stop of blowing device 2 control by the temperature of transformer 1 self, without the need to controlling manually, do not need to adopt thermostat to control yet, structure is simple, both the automatic start-stop of heat abstractor can have been realized, do not need to adopt thermostat to control yet, part parts are saved, reduce production cost of the present utility model.
Because heat abstractor of the present utility model uses by adopting temperature difference electricity generation device 3 to generate electricity to work for blowing device 2, therefore without the need to consuming electric energy that external power source provides or consuming the electric energy that transformer 1 self provides, therefore the social energy can be saved.
Due to blowing device 2 select different motors 21 time, need temperature difference electricity generation device 3 to export different voltage and just can make the work of motor 21 normal rotation, and the voltage that temperature difference electricity generation device 3 exports is except outside the Pass the temperature difference between its hot junction and cold junction has, also relevant with its structure, in the utility model, preferably, described temperature difference electricity generation device 3 is thermal generator or thermo-electric generation sheet.
