Abstract
The invention discloses an external cooling device for transformer oil, which is provided with a cooling pond, a cooling coil, an oil scavenging pump, an oil-controlled valve gate and an umbrella-shaped nozzle. The end face of the cooling coil is provided with a radiating fin, an upper end of the cooling pond is provided with a water collecting pipe and the umbrella-shaped nozzle, and the oil scavenging pump can pump cooling oil into a transformer through the oil-controlled valve gate directly. By means of external cooling of the transformer oil and a structure of oil pump circulation, a remarkable cooling effect of the transformer is obtained under a normal full loading condition, and even in hot summer, over temperature can not occur during full-loading operation of the transformer, thereby overcoming defects of stopping work and production and damaging equipment caused by the fact that the transformer is forced to power off automatically because of operation of a gas relay when temperature rises to be beyond limit.
Description
Technical field the present invention relates to transformer, directly relates to external cooling device of transformer oil, is specially adapted to high pressure and surveys the use of lowering the temperature of the electric power transformer insulated oil body of 6KV-35KV outward.
The background technology high-tension electricity generally all wants the step-down of electrification transformer to use after the user is transmitted; All will dispose transformer, particularly smelting industry in unit and industrial and mining enterprises, the transformer capacity of use is quite big; Smelting furnace uses big electric current; Smelting quality is good, and furnace temperature is high, is extensively adopted by people always.Though yet in use people find that also existing transformer capacity is big, electric current is strong, also has certain weakness, has adopted big electric current acting just because of smelting furnace; Full-load run will certainly cause transformer core seriously to generate heat, and insulating oil heat conduction only depends on the heat radiation of transformer self-radiating sheet, under having ready conditions, can install blower fan blowing carrying out cooling additional; Temperature also is difficult for controlled, and temperature regular meeting reaches depreciation, causes the Buchholz relay action often, forces 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 objective of the invention is to realize like this: external cooling device of transformer oil has cooling pond and cooling coil.
As a kind of improvement of the present invention, the upper end of said cooling pond is provided with the cooling coil of fin.
As further improvement of the present invention, the position, top of said cooling coil is provided with collector pipe and cold water umbrella shower nozzle.
As another kind of improvement the of the present invention, said cooling coil upper end is provided with scavenge oil pump.
As another improvement of the present invention, said scavenge oil pump front end is provided with oil-controlled valve door lock.
The present invention is owing to adopted the cooling coil that is provided with fin in the upper end of cooling pond, the upper end of cooling coil that collector pipe and cold water umbrella shower nozzle are set, and the cooling coil upper end is provided with scavenge oil pump; The scavenge oil pump front end is provided with the structure of oil-controlled valve door lock; Thereby make make transformer that the obvious cooling effect arranged by the very convenient and easy of the external change of transformer oil under normal full load, promptly be hot summer; Overtemperature does not appear in transformer full-load run yet; Thereby also just 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, below in conjunction with accompanying drawing the present invention is described further.
The embodiment accompanying drawing shows the structure of external cooling device of transformer oil of the present invention, and the upper end of cooling pond 9 is provided with the cooling coil 5 of fin 14, and the position, top of cooling coil 5 is provided with collector pipe 13 and cold water umbrella shower nozzle 6.The cooling coil upper end is provided with scavenge oil pump 4, and scavenge oil pump 4 front ends are provided with oil-controlled valve door lock 2.
Installation process of the present invention is: at first cooling coil 5 is fixed in the cooling pond 9, cooling coil 5 one ends connect transformer 1, and the other end connects scavenge oil pump 4, oil-controlled valve door lock 2 valves 3, wire connection 12.Water supply pump 7 one ends connect collector pipe 13, umbrella shower nozzle 6, and the other end connects well casing 8,
Use of the present invention is: after transformer 1 operation; Open valve 3 and fuel outlet valve 10 in advance; So start scavenge oil pump 4, this moment, transformer 1 interior transformer oil and cooling coil 5, scavenge oil pump 4, valve 3, oil-controlled valve door lock 2 and fuel outlet valve 10 promptly constituted path enforcement circulation.And then start water supply pump 7, and open return pipe 11, this moment, cold water can lead to the purpose of the fin realization cooling of collector pipe 13 and 6 pairs of cooling coil 5 upper ends of umbrella shower nozzle.
