Abstract
The utility model discloses a coil winding and casting mould of a solid winding iron-core resin dry insulating type transformer and belongs to the technical field of power equipment; the coil winding and casting mould comprises an inner mould (1) and an outer mould (2); the inner mould is arranged in the outer mould; gear baffle plates (3) are respectively arranged on the upper and lower ends of the inner mould and the outer mould; wherein, the gear baffle plates at the lower end are sealed with lower end surfaces of the inner mould and the outer mould; a rotational rail ring (4) is arranged on the gear baffle plates, and a fixing block (5) fixed with an iron-core column is arranged on the rail ring; the inner mould, the outer mould, the outer mould and the rail ring are respectively divided into at least two blocks along the axial direction, and all blocks are connected by fastening pieces. The coil winding and casting mould integrates a winding mould and a casting inner mould into one body, the cost, and working time are not only saved, but also the problem that the mould is difficult for being assembled after winding is solved. The gear baffle plates not only support and drive the inner mould to finishing winding when in wire winding, but also can be used as bottom plates of the casting mould; the coil winding and casting mould has simple structure, and mould assembling and demoulding are convenient.
Description
Technical field
The utility model belongs to the technical field of power equipment, specifically is meant a kind of coiling of three dimensional wound core resin insulating dry type transformer and casting mold of being used for.
Background technology
Traditional laminated core poured with epoxy resin dry-type transformer, normally earlier that winding technique is good, refill mould and pour into a mould, carry out the suit of winding after cast is good again.But remain silent for the Wound iron-core transformer for solid, winding is directly on core limb, dress mould, the demoulding all will be subjected to great spatial limitation like this, be applicable to three dimensional wound core winding resin insulating dry type transformer coil and casting mold so must design a cover.
The utility model content
The utility model purpose is to provide a kind of coiling of three dimensional wound core resin insulating dry type transformer and casting mold of adorning mould, being convenient in demoulding.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: three dimensional wound core winding resin insulating dry type transformer coil and casting mold, the internal mold and the external mold that comprise tubular, internal mold is located in the external mold, the two ends up and down of internal mold and external mold are respectively equipped with the gear plate washer, wherein the gear plate washer and the internal mold of lower end, the lower surface of external mold seals mutually, the gear plate washer is provided with rotating orbit ring, orbit ring is provided with the fixed block that can fix with core limb, described internal mold, external mold, the gear plate washer, orbit ring is divided at least two vertically, connects by securing member between each piece.
Earlier internal mold, external mold, gear ring and orbit ring are taken apart and be enclosed within on the core limb again, two fixed blocks are separately fixed at the two ends of core limb, start coil winding machine, and the transmission by the gear baffle plate drives the coiling that the internal mold of fixing on it is finished winding.Internal mold both had been a winding former, was again the internal mold of cast.Can pour into a mould after coiling is finished, behind the casting complete, securing member unclamps, can be with under internal mold, external mold, gear ring and the orbit ring blocked breaking.
The utility model unites two into one winding former and cast internal mold, has not only provided cost savings, man-hour, but also has solved the problem of dress mould difficulty after the coiling.The gear baffle plate has both supported, has driven the coiling that internal mold is finished winding in when coiling, again when cast as the base plate that waters injection molding.The utility model is simple in structure, the dress mould, be convenient in demoulding.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, but does not constitute any restriction of the present utility model.
As shown in Figure 1, three dimensional wound core winding resin insulating dry type transformer coil described in the utility model and casting mold, the internal mold 1 and the external mold 2 that comprise tubular, internal mold 1 is located in the external mold 2, the two ends up and down of internal mold 1 and external mold 2 are respectively equipped with gear plate washer 3, wherein the gear plate washer 3 of lower end and internal mold 1, the lower surface of external mold 2 seals mutually, gear plate washer 3 is provided with rotating orbit ring 4, orbit ring 4 is provided with the fixed block 5 that can fix with core limb, described internal mold 1, external mold 2, gear plate washer 3, orbit ring 4 is divided at least two vertically, connect by securing member between each piece, the contact-making surface that each parts connects is placed the sealing offset plate and is sealed.
Be provided with guide vane end stop 6 between described internal mold 1 and the external mold 2, its effect is to support between internal mold 1 and external mold 2, guarantees the distance between the inside and outside mould, thereby guarantees the thickness of pouring layer.
Elder generation takes internal mold 1, external mold 2, gear ring 3 and orbit ring 4 apart and is enclosed within on the core limb again, and two fixed blocks 5 are separately fixed at the two ends of core limb.Start coil winding machine, the transmission by gear baffle plate 3 drives the coiling that the internal mold of fixing on it 1 is finished winding.Internal mold 1 both had been a winding former, was again the internal mold of cast.Can pour into a mould after coiling is finished, during cast that iron core is upright, behind the casting complete, securing member unclamps, can be with under internal mold 1, external mold 2, gear ring 3 and orbit ring 4 blocked breakings.
Claims (2)
1. three dimensional wound core winding resin insulating dry type transformer coil and casting mold, it is characterized in that: the internal mold (1) and the external mold (2) that comprise tubular, internal mold (1) is located in the external mold (2), the two ends up and down of internal mold (1) and external mold (2) are respectively equipped with gear plate washer (3), wherein the gear plate washer (3) of lower end and internal mold (1), the lower surface of external mold (2) seals mutually, gear plate washer (3) is provided with rotating orbit ring (4), orbit ring (4) is provided with the fixed block (5) that can fix with core limb, described internal mold (1), external mold (2), gear plate washer (3), orbit ring (4) is divided at least two vertically, connects by securing member between each piece.
