Abstract
The utility model relates to a dry-type continuous coil which is continuously wound by positive and negative cakes, and is free from section and the layers are insulated. The internal space of the coil is adequately utilized and the filling coefficient is high. A section position is just reserved at a section tap of the coil. A winding former during coil winding is not needed to turn round so that the operating difficulty is reduced and the winding working hour is saved. For the whole coil, expect the branching taps are welded, no other parts are welded so that the dry-type continuous coil is simple to operate and the fault risk is reduced. The head and the tail of the coil are coated by insulating materials, and the initial voltage distribution of the coil is improved so that the coil can meet the required insulating level completely. The size of a transformer is reduced correspondingly by the compact structure of the whole coil, the loss is reduced, and meanwhile raw materials of the transformer are further saved.
Description
Technical field
The utility model relates to a kind of dry type continuous winding.
Background technology
At present; The coil of dry-type transformer adopts insulation system between subsection cylindrical formula belt basically; Decision is divided according to the height of coil voltage the hop count and the number of plies, common 10kV coil generally is divided into 4 sections 9 layers, if coil voltage reaches 35kV; The coil hop count can reach 8 ~ 12 sections, and the number of plies can reach 11 ~ 15 layers.Since in winding process coil be one section one section around, will be after intact one section, and will lead be cut off with the winding former tune again around another section, wait and weld again after having transferred, hop count coil soldering tip more at most is many more, has increased the coiling difficulty greatly.And the intersegmental distance of coil will satisfy the double requirements of insulation and machinery, and the layer insulation of coil will satisfy the requirement of electric insulation, can reduce the activity coefficient of whole winding like this, and the volume of whole transformer of corresponding increase does not have the effect of materials saving.
Summary of the invention
The purpose of the utility model is to provide a kind of dry type continuous winding, and the inner space of this dry type continuous winding is effectively made full use of, and activity coefficient is high; It is convenient for production to wind the line, and help enhancing productivity, and the whole compact structure of coil makes corresponding volume of transformer reduce, and has also practiced thrift the raw material of transformer when reducing the wastage.
The technical scheme of the utility model is: a kind of dry type continuous winding, comprise insulating cylinder, and it is characterized in that: the said insulating cylinder outside in axial direction is arranged at intervals with positive cake coil and anti-cake coil.
Briefly, said positive cake coil is the coil of radially reeling from inside to outside.Said anti-cake coil is the ecto-entad coil of reeling radially.
The advantage of the utility model is:
The one, no intersegmental, layer insulation, the coil inside space is effectively made full use of, and activity coefficient is high;
The 2nd, only leave an intersegmental position in coil grading tap place, winding former need not to turn around during coil winding, reduces operation easier and practices thrift coiling man-hour;
The 3rd, whole winding does not have other soldering tips again except the welding of shunting tap, and is simple to operate, reduces failure risk; The insulating material of employing end to end at coil adds bag, improves the coil starting voltage and distributes, and makes coil can satisfy desired insulation level fully;
The 4th, the whole compact structure of coil makes corresponding volume of transformer reduce, and has also practiced thrift the raw material of transformer when reducing the wastage.
Description of drawings
Fig. 1 is the background technology structural representation.
Fig. 2 is the structural representation of the dry type continuous winding among the embodiment.
Among the figure: 1-insulating cylinder, 2-positive cake coil, 3-anti-cake coil.
Embodiment
For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and conjunction with figs., elaborates as follows.
With reference to Fig. 1 and 2, the dry type continuous winding of the utility model comprises insulating cylinder 1, it is characterized in that: said insulating cylinder 1 outside in axial direction is arranged at intervals with positive cake coil 2 and anti-cake coil 3.
More particularly, said positive cake coil is the coil of radially reeling from inside to outside.Said anti-cake coil is the ecto-entad coil of reeling radially.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
