The present invention relates to a kind of composite type winding, be with 6 to constitute by high pressure winding 3, composite type square ring 4, composite type corner ring 5 and deflation, it is characterized in that: in described high pressure winding 3 each limit the outside be wrapped in composite type square ring 4, and corner in the outside composite type corner ring 5.
Described high pressure winding 3 interior circle filler strips 7 and outermost turn filler strip 8 hold lead 9.
Described composite type square ring 4 is made up of cardboard 2 and the DMD paper 1 that are nested in the cardboard 2.
Described composite type corner ring 5 is made up of cardboard 2 and the DMD paper 1 that are nested in the cardboard 2.
The thickness of described cardboard 2 is 0.5-1mm.
The thickness of described DMD paper 1 is 0.15-0.5mm.
Described composite type square ring 4 width are 75-105mm.

Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is further described, but claimed scope is not limited only to following description.
Composite type winding as shown in Figure 1 was with for 6 some compositions by high pressure winding 3, composite type square ring 4, composite type corner ring 5, deflation.Wherein composite type square ring 4 is wrapped in the long limit of high pressure winding 3 and the interior outside of minor face, and composite type corner ring 5 is wrapped in the inboard of high pressure winding 3 corners, is with 6 bundle to be bundled into the composite type winding construction with tightening.Make high pressure winding 3 structures of moulding be tending towards a firm state.
As shown in Figures 2 and 3, composite type square ring 4 and composite type corner ring 5 are to be that the cardboard 2 of 0.5-1mm and DMD paper 1 that thickness is 0.15-0.5mm combine by thickness, and are shaped as " U " type groove.Wherein cardboard 2 and DMD paper 1 all are a kind of materials with insulation property, and the requirement to cardboard 2 and DMD paper 1 thickness has effectively taken into account cost and best insulation effect.Simultaneously, high pressure winding 3 is by the parcel of composite type square ring 4 and composite type corner ring 5, " U " type groove makes square ring better be wrapped in winding, strengthened high pressure winding 1 to dielectric strength unshakable in one's determination, the electric discharge phenomena of winding end face have been prevented, slow down the ageing of insulation of high pressure winding 3, prolonged the useful life of winding construction in transformer.
The partial enlarged drawing of composite type winding construction as shown in Figure 4 and Figure 5, the present invention is when winding technique, the lead 9 of coiling according to winding around increasing interior circle filler strip 7 to the lead 9 at the winding medial surface, when coiling increases outermost turn filler strip 8 according to the winding width of cloth to size during to the circle last of be about to expiring circle, turn to high pressure winding 3.During winding technique, winding conducting wire 9 adopts the insulation filler strip to hold together at interior circle and outermost turn, and inside and outside filler strip is according to the needs of interior circle and outermost turn, do corresponding increase according to the different size of inside and outside circle, effectively lead 9 is wrapped up the insulator structure that forms a sealing, reduced the composite type winding construction in processing and manufacturing, combination, handling process to the damage of wire insulation body structure, improved the performance of winding, prolonged the useful life of transformer.
After the winding moulding, the combination square ring of being made up of as shown in Figures 2 and 3 cardboard 2 and DMD paper 14 encases interior foreign minister limit and the minor face of high pressure winding 3 respectively, be with 6 wrappings fixing with deflation, the inside and outside minor face winding leads in the top of high pressure winding 3 is lifted one's head both sides, encase the interior survey corner of high pressure winding 3 again with combination corner ring 5, and be with 6 wrappings to fix with deflation and can carry out shaping or other operations.
The present invention adopts composite type square ring and composite type corner ring, prevents the discharge of high pressure winding end face, prevents the quick aging of insulating, and improves the performance of winding, has prolonged the useful life of transformer.
