Abstract
The invention discloses an external cooling device of transformer oil, provided with a cooling pond, a cooling coil, an oil-scavenging pump, an oil-controlled valve gate and umbrella-shaped nozzles. Cooling fins are arranged on the end surface of the cooling coil, a water-collecting pipe and the umbrella-shaped nozzles are arranged at the upper end of the cooling pond, and cooling oil can be directly pumped into a transformer by the oil-scavenging pump through the oil-controlled valve gate. Due to the adoption of the external cooling of the transformer oil for lowering the temperature and the circulating structure of the oil pump in the invention, the transformer has obviously cooling effect in a normal full-load state and can not be overheated in the full-load state even in hot summer so as to avoid the severe defects of work and production standstill and equipment damage caused by the action of a gas relay because the temperature raises to exceed a limit, and the transformer is automatically power-down.
Description
Technical field the present invention relates to transformer, directly relates to external cooling device of transformer oil, is specially adapted to the use of lowering the temperature of the electric power transformer insulated oil body of high-pressure side 6KV-35KV outward.
Background technology all disposes transformer, particularly smelting industry in industrial and mining enterprises, and the transformer capacity of use is quite big, and smelting furnace uses big electric current, and smelting quality is good, and the furnace temperature height is extensively adopted by people always.Though yet in use people find that also existing transformer capacity is big; electric current is strong; but also there is certain weakness; adopted big electric current acting just because of smelting furnace; full-load run; will certainly cause transformer core seriously to generate heat, insulating oil heat conduction is by transformer self-radiating sheet heat radiation and install blower fan blowing exothermic temperature additional and also be difficult for controlledly, and temperature regular meeting reaches depreciation; cause the Buchholz relay action; force transformer to cut off the power supply automatically, therefore, because the transformer outage; temperature descends in the body of heater; the material body solidifies, and damage equipment causes stop work and production, directly causes heavy economic losses to country.
Summary of the invention the present invention will provide a kind of external cooling device of transformer oil exactly, and it can overcome existing transformer effectively and have fully loaded overtemperature since the dawn of human civilization, will occur the drawback of outage automatically when temperature reaches the cutting edge of a knife or a sword value.
The present invention is achieved in that external cooling device of transformer oil, has cooling pond and cooling coil, scavenge oil pump.
As a kind of improvement of the present invention, the upper end of described cooling pond is provided with the cooling coil of fin.
As a further improvement on the present invention, the upper end of described cooling coil is provided with collector pipe and cold water umbrella shower nozzle.
As another kind of improvement the of the present invention, described scavenge oil pump is high temperature resistant oil pump, artificial control.Work another for backing up for one.
As another improvement of the present invention, described oil-controlled valve door lock is for opening automatically and cutting out automatically.
The present invention is owing to adopted the external cold water cooling of transformer oil, oil pump is implemented the structure of circulation, thereby make transformer that the obvious cooling effect arranged under normal full load, it promptly is hot summer, overtemperature does not appear in transformer full-load run yet, thereby avoided the action of Yin Wendu rising Buchholz relay, forced transformer to cut off the power supply automatically, caused the great drawback of stop work and production damage equipment.
Appended drawings is the structure principle chart of external cooling device of transformer oil of the present invention, and the invention will be further described below in conjunction with accompanying drawing.
The embodiment accompanying drawing shows the structure of external cooling device of transformer oil of the present invention, cooling coil 5 is set in the cooling pond 9, cooling coil 5 upper ends are provided with collector pipe 13 and umbrella shower nozzle 6, cooling coil 5 one ends are provided with fuel outlet valve 10, the other end is provided with scavenge oil pump 4, oil-controlled valve door lock 2 one ends are provided with valve 3 other ends silk joint cover 12 are set, water supply pump 7 collector pipes 13. end faces are provided with umbrella shower nozzle 6, the other end connects well casing 8, return pipe 11 1 ends connect cooling pond 9. installation processes of the present invention: at first cooling coil 5 is fixed in the cooling pond 9, cooling coil 5 one ends connect transformer 1 fuel outlet valve 10, connect scavenge oil pump 4, oil-controlled valve door lock 2 one ends connect valve 3, and the other end and wire connection 12 transformer 1 connect firmly.Water supply pump 7 one ends connect collector pipe 13, umbrella shower nozzle 6, and the other end connects well casing 8, and return pipe 11 connects cooling pond 9.
