Description
Technical field
The present invention relates to a kind of shaper for being used to make insulating cylinder.
Background technology
There is an insulation distance between the high and low pressure coil of Cast Resin Dry-Type Transformer, usually this is insulated
Distance referred to as main empty path.If main empty path is too small, it cannot meet the insulating requirements between high and low pressure coil；Main empty path is excessive,
Transformer manufacturing cost can be increased again.The insulating cylinder that suitable dimension is placed in main empty path is (a kind of to be poured for being placed on epoxy resin
The seal of insulating effect is played between the high-tension coil and low-voltage coil of note dry-type transformer coil), high and low pressure can be homogenized
Field strength distribution between coil, strengthens the insulating requirements of transformer.The shape of epoxy-resin-poured is general
There is the rectangle three kinds (cross sections) that circle (cross section), oval (cross section) and corner are fillet, respectively such as attached drawing 1, attached drawing 2
And shown in attached drawing 3, it will be appreciated that the shape of insulating cylinder equally exists circular (cross section), oval (cross section) and corner is
Three kinds of classifications (cross section) such as rectangle of fillet.
Insulating cylinder is usually to be rolled to form by PET composite polyester film insulation flexible plates, the lower above-mentioned three classes of surface analysis
The manufacturing process of insulating cylinder, wherein, section is relatively simple for the manufacturing process of circular insulating cylinder, by PET composite polyester films

Position, in lap-joint, with 3M insulating tapes, inside and outside sealing part pastes jail, as shown in Figure 4；Section is exhausted for oval and rectangle
Edge cylinder manufacturing process is relatively complicated, makes the mould identical with its shape first, mould is through on square shaft, be then fitted into around
On line machine, PET composite polyester film insulation flexible plates are set on mould, with tightening belt (length direction meeting after one kind is heated
The band of contraction) binding method PET composite polyester film insulation flexible plates are fixed on mould, such as attached drawing 5 and the institute of attached drawing 6
Show, wherein, the material of mould is generally steel or cast aluminium, is formed by machine finishing, and cost is higher, and different product
The barrel shape that insulate is different, and it is huge such as to correspond mould input cost；Then heat to be carried out into drying chamber fixed together with mould
Shape, due to made of metal material mould caloric receptivity it is larger, whole thermo setting time take around 3~5 it is small when (in a fixed number
Under amount), heat setting terminates to cool down, takes off tightening belt (can only be disposable) form removal, then as round insulation cylinder
Method with insulating tape inside and outside Sealing piece jail.
From upper analysis, the existing process for making insulating cylinder exists, and the material of mould is generally steel or cast aluminium, passes through
Cross machine finishing to form, cost is higher, and the insulation barrel shape of different product is different, and die cost input is high；Heat is fixed
The type time is grown, and energy consumption is big；Tightening belt can only be disposable, it is necessary to waste a large amount of tightening belts, i.e. waste of materials.
The content of the invention
