Description
Technical field
The utility model relates to a kind of oil tank of transformer, especially a kind of large oil immersed formula oil tank of transformer.
Background technology
Transformer is owing to there being the existence of iron loss and copper loss in running, and these losses are all outwards dispersed energy transform into heat energy, thereby causes transformer constantly heating and temperature rising.And transformer capacity is larger, the loss producing is more, the power conversion of loss is that heat makes transformer heating, and outwards transmit by the hot conduction and convection effect of transformer insulation oil, heat rises winding, iron core, oil tank wall and oil surface temperature, surpass the temperature rise level that transformer allows, light reduce useful life of transformer, heavy damage transformer.
The conventional type of cooling of high-power transformer is generally divided into three kinds at present: oil-immersed self-cooled, oil-immersed forced-air cool, forced oil-circulation formula.Oil-immersed self-cooled is exactly to take heat to oil tank wall and radiating tube by oily Effect of Nature Convection, then relies on the convection current conduction of air by dissipation of heat, and this type of cooling does not have special cooling device conventionally; But this type of cooling cooling rate is slow, cooling effectiveness is not high, particularly during summer high-temperature high load capacity, more than the temperature of high-power transformer still can reach 80 degree.Oil-immersed forced-air cool is on the basis of oil-immersed self-cooled, on oil tank wall or radiating tube, installs fan additional, utilizes hair-dryer to help cooling; The cooling effect of this type of cooling is relatively better, but has the shortcoming that fan electromotor loss is large, cost is high.Forced oil-circulation formula is to utilize oil pump to squeeze into after oil cooler is taken away heat the oil in transformer to return to fuel tank again; The cooling effect of this type of cooling is relatively better, but exists the loss of electric machine large, the shortcoming that cost is high.
In addition, what the oil-immersed pump of high-power transformer tank cooler adopted is general all iron pump, during oil-immersed pump operation, can produce metal dust, as fuel pump impeller and the fricative metal dust of pump case and enter in the working connection of transformer, easily causes multipoint earthing unshakable in one's determination.
Summary of the invention
The purpose of this utility model is just to provide a kind of large oil immersed formula oil tank of transformer, solves problems of the prior art.
The purpose of this utility model is achieved through the following technical solutions: a kind of large oil immersed formula oil tank of transformer, comprise tank body of oil tank, gilled radiator, cooling system, described tank body of oil tank evenly arranges several gilled radiators outward, each gilled radiator is by oil inlet pipe, flowline and tank body of oil tank UNICOM, described cooling system comprises the cooling water pipe that is positioned at each gilled radiator top, cooling water pipe is connected with cistern by water pump, and each cooling water pipe offers osculum in the position that is positioned at fin upside.
Further, described cooling water pipe comprise some transverse arrangement of turbo with two water pipes of longitudinally arranging, the water pipe two ends of described transverse arrangement of turbo are communicated with the two ends of longitudinal layout water pipe respectively, have several osculums on the water pipe of transverse arrangement of turbo.
Further, the below of described gilled radiator is provided with for collecting the water leg of cooling water, and water leg is connected by pipeline with cistern.
Further, the flowline place of each gilled radiator and tank body of oil tank UNICOM is provided with filter screen.
The utlity model has following beneficial effect:
The utility model tank body of oil tank evenly arranges several gilled radiators outward, each gilled radiator and tank body of oil tank UNICOM, each gilled radiator top is provided with cooling water pipe, cooling water pipe is connected with cistern by water pump, and each cooling water pipe offers osculum in the position that is positioned at fin upside.Water pump is sent the cooling water in water storage container into cooling water pipe and is discharged to fin and lowered the temperature by osculum, and tank is collected to the cooling water after fin cooling and is recycled in tank by drainage pipe.Because specific heat of water is large, the heat that cooling water absorbs is more than air-cooled mode, and the water velocity of cooling water is fast, so the relatively air-cooled mode of cooling effect is better, can make the temperature of high-power transformer decline more than 20 degrees Celsius.In addition, the flowline place of each gilled radiator and tank body of oil tank UNICOM is provided with filter screen, so the utility model can avoid the impurity such as metal dust to enter in the working connection of transformer.The utlity model has good heat dissipation effect, equipment loss is little, use cost is low advantage.

Fig. 3 is the schematic diagram of the utility model cooling system.
In figure, tank body of oil tank 1, gilled radiator 2, cooling water pipe 3, osculum 31, water leg 4, oil inlet pipe 5, filter screen 6, flowline 7, cistern 8.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, a kind of large oil immersed formula oil tank of transformer, comprise tank body of oil tank 1, gilled radiator 2, cooling system, outer several gilled radiators 2 that evenly arranges of described tank body of oil tank 1, each gilled radiator 2 is by oil inlet pipe 5, flowline 7 and tank body of oil tank 1 UNICOM, described cooling system comprises and is positioned at each gilled radiator top cooling water pipe 3, and cooling water pipe is connected with cistern 8 by water pump, and each cooling water pipe 3 offers osculum 31 in the position that is positioned at fin upside.
Further, described cooling water pipe 3 comprise some transverse arrangement of turbo with two water pipes of longitudinally arranging, the water pipe two ends of described transverse arrangement of turbo are communicated with the two ends of longitudinal layout water pipe respectively, have several osculums 31 on the water pipe of transverse arrangement of turbo.
Further, the below of described gilled radiator 2 is provided with for collecting the water leg 4 of cooling water, and water leg 4 is connected by pipeline with cistern 8.
Further, the flowline place of each gilled radiator and tank body of oil tank UNICOM is provided with filter screen 6.
Water pump is sent the cooling water in water storage container into cooling water pipe and is discharged to gilled radiator fin and lowered the temperature by osculum, and tank is collected to the cooling water after fin cooling and is recycled in tank by drainage pipe.Oil in fuel tank enters gilled radiator from oil inlet pipe, enters fuel tank after cooling by flowline.Because specific heat of water is large, the heat that cooling water absorbs is more than air-cooled mode, and the water velocity of cooling water is fast, so the relatively air-cooled mode of cooling effect is better, can make the temperature of high-power transformer decline more than 20 degrees Celsius.In addition, the flowline place of each gilled radiator and tank body of oil tank UNICOM is provided with filter screen, so the utility model can avoid the impurity such as metal dust to enter in the working connection of transformer.
Above-described, be only preferred embodiment of the present utility model, can not limit the scope that this practicality is implemented, every equalization of doing according to the utility model claim changes, and all should still belong in the scope that the utility model contains.
