Abstract
The utility model relates to an oil-immersed on load capacity-regulated transformer, which comprises a transformer housing, an iron core column arranged in the transformer housing, and coil windings sleeved on the iron core column. The coil windings are spaced layer by layer by a layer of adhesive injecting paper, the two sides of the adhesive injecting paper are coated with grid-shaped modified epoxy resin, and the adhesive injecting paper has the following characteristics that: the thickness is 0.06-1.00mm, the breakdown voltage is not lower than 4000V, the tensile strength of one side is not below 120Ma while that of the other side is not below 200MPa, and the bonding strength of the two sides are not below 380KPa. By adopting the adhesive injecting paper with the specification, the insulation among the coil windings of the transformer of 315KVA-10000V can be realized by only setting only one layer of the adhesive injecting paper, thus, the volume of the transformer is reduced, the amount of the used metal is decreased, and the cost of the transformer is lowered.
Description
Technical field
The utility model relates to a kind of oil-immersed on-load capacitance-adjustable transformer.
Background technology
At present, the coil windings interlayer of transformer can be placed insulating material, increases distance by insulating material, guarantees the good of electric property.And the performance of insulating material has directly influenced the performance of transformer.In the prior art, insulating material commonly used has cardboard, insulating varnish plate, insulating paper etc., and according to the difference of its insulation property, the quantity that is placed on the coil windings interlayer is also different.Now the insulating paper with following specification is an example: insulating paper thickness is 0.07～0.09mm; Puncture voltage is not less than 800V; Hot strength is not less than 36MPa; Adhesion strength is not less than 380KPa, the insulating paper of specification uses at rated capacity 315KVA like this, on the transformer of rated voltage 10000V, need be provided with 4, as every paper thickness is 0.08mm, the thickness of the insulating paper that every interlayer increases be 0.32mm just, is 11 layers as the number of plies of coil windings, and the thickness that whole winding increases is 3.2mm just.The volume of transformer increases like this, and loss also increases thereupon, influences cost and energy-conservation.
Summary of the invention
The utility model provides a kind of oil-immersed on-load capacitance-adjustable transformer.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of oil-immersed on-load capacitance-adjustable transformer, comprise the transformer housing, be arranged on described transformer housing inside iron core column, be enclosed within on the described iron core column the several layers coil windings, pass through the some gummed paper between every layer of described coil windings separately, described some gummed paper is provided with 1 layer, the two-sided of described some gummed paper is coated with the form diamond checks modified epoxy, has following characteristic:
The thickness of described some gummed paper is 0.06～1.00mm; The puncture voltage of described some gummed paper is for being not less than 4000V; The hot strength that the hot strength of described some gummed paper one side is not less than 120MPa, another side is not less than 200MPa; The adhesion strength on described some gummed paper two sides is not less than 380KPa.
Preferably, described coil windings is provided with 11 layers.
Because technique scheme utilization, the utility model compared with prior art has following advantage: the utility model is by adopting the some gummed paper of above-mentioned specification, between coil windings, only one deck need be set, just can satisfy the insulation between the transformer coli winding of 315KVA/10000V, effectively reduced volume of transformer, reduce the use amount of metal, reduced the cost of transformer.

Accompanying drawing 1 is the schematic diagram that is provided with of of the present utility model some gummed paper.
Wherein: 1, some gummed paper; 2, coil windings.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
A kind of oil-immersed on-load capacitance-adjustable transformer, comprise the transformer housing, be arranged on transformer housing inside iron core column, be enclosed within the coil windings on the iron core column.As shown in Figure 1,1 by some gummed paper 2 separately between every layer line circle winding, and some gummed paper 1 is provided with 1 layer, puts the two-sided of gummed paper 1 and is coated with the form diamond checks modified epoxy, has following characteristic:
The thickness of some gummed paper 1 is 0.06～1.00mm; Puncture voltage is for being not less than 4000V; The hot strength of some gummed paper 1 simultaneously is not less than 120MPa, and another side then is not less than 200MPa; The adhesion strength two sides of some gummed paper 1 all is not less than 380KPa.
Present embodiment is with rated capacity 315KVA, the transformer of rated voltage 10000V is an example, 1 of the some gummed paper that needs 0.08mm, the number of plies as coil windings is 11 layers, the thickness that whole winding increases is 0.8mm just, and 0.32mm has compared to existing technology reduced the overall size of coil greatly, the volume of transformer is reduced, reduce the transformer cost.
The point gummed paper of present embodiment also has good oil resistance in addition, and the energy long period of soaking is in the cold oil that oil becomes.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
