Abstract
The utility model relates to a mute oil-immersed transformer which comprises a transformer box body, insulation cooling oil added into the transformer box body and a winding immersed into the insulation cooling oil. The winding is formed by an iron core and a coil tightly wound around the surface of the iron core. The iron core is formed by stacking a plurality of sets of 8-shaped silicon steel sheets. An 8-shaped EVA adhesive film pad is arranged between every two adjacent sets of 8-shaped silicon steel sheets in an interlaid mode. Each set of 8-shaped silicon steel sheet comprises four to six 8-shaped silicon steel sheets. The size of the 8-shaped EVA adhesive film pads is smaller than the size of the 8-shaped silicon steel sheets. According to the mute oil-immersed transformer, the EVA adhesive film pads are arranged in the iron core in the interlaid mode, the iron core is formed by stacking the 8-shaped silicon steel sheets, resonance generated during magnetostriction of the silicon steel sheets is weakened through flexibility and elasticity of the EVA adhesive film pads, and noise generated when the transformer works is reduced; meanwhile, the middle of a basalt fiber composite board is provided with a certain hole and space, and the noise generated inside the transformer can be effectively filtered out and relieved.
Description
Technical field
The utility model relates to a kind of oil-immersed type transformer, is specifically related to a kind of squelch type oil-immersed type transformer.
Background technology
Oil-filled transformer is the significant components of transformer station, and oil-filled transformer is generally arranged in independent transformer room.Rely on oil to make coolant, as oil, oil, oil immersed water cool and forced oil-circulation etc.The main transformer of general booster stations is all oil immersed type, no-load voltage ratio 20KV/500KV, or 20KV/220KV, general power plant is for being with self load (such as coal pulverizer, induced draft fan, forced draft fan, circulating water pump etc.) station transformer be also oil-filled transformer, its no-load voltage ratio is 20KV/6KV.Therefore, unit and industrial and mining enterprises all will configure transformer, particularly smelting industry, and the transformer capacity of use is quite large, and smelting furnace uses large electric current, and smelting quality is good, and furnace temperature is high, is extensively adopted by people always.
High magnetic effect orientating-sensitive sheet is the important materials of transformer core, along with the increase of transformer capacity, control transformer noise and reduction no-load loss seem particularly important, and the one of the main reasons that transformer noise produces is exactly the magnetostriction of silicon sheet core, magnetostriction is exactly that silicon steel sheet is in magnetization process, ferromagnetic length changes, although the variation of length only has millions of/mono-, but this also can produce sound wave, therefore study low magnetostriction or just more and more come into one's own without magnetostrictive silicon steel sheet, because silicon steel sheet face coat can exert an influence to its performance, therefore people utilize insulating coating to make silicon steel sheet be subject to certain pulling force to change domain structure in recent years, improve magnetic.This insulating coating has low thermal coefficient of expansion.Because the difference of the thermal coefficient of expansion of coating and silicon steel sheet is larger, both shrinkage differences when cooling, coating can make silicon steel sheet be subject to certain pulling force, thereby can reduce the loss of silicon steel sheet Unit Weight and reduce the magnitude of magnetostriction of silicon steel sheet.
But, coating is set on silicon steel sheet only reduces himself magnitude of magnetostriction, can not thoroughly eliminate, when after multi-disc silicon steel sheet is stacked, under superposition, noise problem highlights again mutually.
EVA is the copolymer of ethene and vinylacetate VA, be a kind of hot-melt plastic, EVA rubber cushion has outstanding high and low temperature resistance, keeps good use elasticity in the temperature range of-70 DEG C-+260 DEG C, resistance to ozone, Weather-resistant, should make the sealing gasket in thermomechanical.Nontoxic thermal insulation, insulated product and the druggist rubber sundrier made of EVA.EVA has the premium properties such as waterproof, fire-retardant, high temperature resistant, conduction, wear-resisting, oil resistant, is widely used in the multiple industries such as machinery, electronics, hot-water heating.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of transformer that can further weaken work noise.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of quiet oil-filled transformer, comprise transformer-cabinet, add the insulation cold oil of note in described transformer-cabinet and be immersed in the winding in described insulation cold oil, winding is by iron core and tightly forms around the coil on described iron core surface, described iron core is by many groups day font silicon steel sheet stacked composition, the day font silicon steel sheet therebetween of every two adjacent groups is provided with day font EVA glued membrane pad, every group day font silicon steel sheet include 4-6 sheet day font silicon steel sheet, the size of described day font EVA glued membrane pad is less than the size of described day font silicon steel sheet.
Further, described transformer-cabinet is by glueing joint and form after the splicing of basalt fibre composite plate.
Further, described transformer tank external surface is bonded with spaced apart radiating fin by adhesive.
The beneficial effects of the utility model are:
The utility model is folded with EVA glued membrane pad in by the stacked iron core forming of multilayer day font silicon steel sheet, by utilizing the flexibility of EVA glued membrane pad and elasticity to weaken the resonance that multilayer silicon steel sheet produces when the magnetostriction, reduce the noise that transformer produces in the time of work.
And the middle part of basalt fibre composite plate has certain hole and space, can be effectively by by the inner noise filtering producing of transformer with alleviate.
Brief description of the drawings
Below in conjunction with accompanying drawing, quiet oil-filled transformer of the present utility model is described further.
Fig. 1 is the structural representation of winding.
Fig. 2 is the structure explosive view of iron core.
Embodiment
Shown in Fig. 1 and Fig. 2, quiet oil-filled transformer in the utility model, comprise transformer-cabinet, add the insulation cold oil of note in described transformer-cabinet and be immersed in the winding in described insulation cold oil, winding is by iron core 1 and tightly forms around the coil 2 on described iron core 1 surface, described iron core 1 is by many groups day 3 stacked compositions of font silicon steel sheet, every two groups of adjacent day font silicon steel sheet 3 therebetween are provided with day font EVA glued membrane pad 4, every group day font silicon steel sheet 3 include 4-6 sheet day font silicon steel sheet 3, the size of described day font EVA glued membrane pad 4 is less than the size of described day font silicon steel sheet 3.
Described transformer-cabinet is by glueing joint and form after the splicing of basalt fibre composite plate.
Described transformer tank external surface is bonded with spaced apart radiating fin by adhesive.
The above-described embodiment that is not limited to of the present utility model; the technical scheme of above-mentioned each embodiment of the present utility model can combined crosswise form new technical scheme each other; all employings are equal to the technical scheme of replacing formation in addition, all drop in the protection range of the utility model requirement.
