Abstract
A transformer winding die belongs to dies, and mainly solves the problem that a winding die for an ellipsoidal iron core lacks in the industrial production. The transformer winding die comprises a columnar winding die, wherein the cross section of the winding die is manufactured into an ellipsoidal die with two straight sides, the upper arc portion, the lower arc portion and the straight section portion of the die are designed into groove structures, and reinforcing plates are arranged inside the upper and the lower arc portions, thereby the winding die can be specially used for winding a coil winding with two straight sides and ellipsoidal cross section. As the straight section portions are designed into groove structures, the coil winding can not generate edges during the winding process, and can form a coil structure which is evenly distributed, thereby guaranteeing the electric performances of a transformer.
Description
Technical field
The utility model relates to a kind of mould, specifically a kind of winding mould of transformer special use.
Background technology
In present transformer Electromagnetic Design, the iron core of most of transformer all is designed to cylindrical structural, so it is cylindric that its coil windings also can be designed to, so that snugly fit on the cylindrical core, coil windings can directly be twined in transformer fe in the heart, also can on the winding mould, twine, and then be installed on the iron core, common winding mould is columniform, but for both sides is the elliptic cross-section transformer core of straight flange, make if directly on the mould of this structure, twine, form unnecessary corner angle at arcuate structure and straight flange structure interface place easily, influence the use of transformer.So lack a kind of mould that above-mentioned oval transformer core winding uses that is suitable for now in the industrial production.
The utility model content
At lack in the existing industrial production that above-mentioned oval ironcore choke winding uses mould, the utility model provides a kind of mould that both sides are the oval coil winding use of straight flange that is specially adapted for, this mould is by being that the oval mould of straight flange partly is provided with groove with both sides, can prevent effectively that unnecessary corner angle from appearring in coil windings when twining, influence the use of transformer.
The concrete technical scheme that the utility model adopts is: a kind of Transformer Winding mould, comprise cylindricality winding mould, it is characterized in that, described winding mold sections is set as the oval mould that both sides are straight flange, the part of segmental arc up and down of mould partly is set as groove structure with straight section, usually the width setting with the straight section part is lower than the segmental arc part, thereby forms a groove.Because segmental arc part partly forms groove with straight section, thus in winding process the ground floor coil near mould, when coil around behind certain size, the coil both sides just become straight line portion, have guaranteed the insulation distance between coil and the iron core; Advanced technique for coiling makes winding that higher dielectric strength be arranged, and the load loss of transformer is lower, and electric property is more reliable, and anti-short circuit capability is stronger.
Be provided with stiffener in the segmental arc about described,, influence winding and use to guarantee that this mould can not be out of shape when coil windings is twined.
The beneficial effects of the utility model are: this Transformer Winding mould is lower than the height of arc section by the height setting with the straight section part, making this winding mould can be used for the coiling both sides specially is the coil windings of the elliptic cross-section of straight flange, because straight section partly is set as groove structure, make coil windings when twining, can not produce corner angle, but form equally distributed loop construction, guaranteed the electric property of transformer.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is a left view of the present utility model.
The 1st, last segmental arc, the 2nd, following segmental arc, the 3rd, straight section, the 4th, stiffener, the 5th, support plate, the 6th, positive backward leading screw, the 7th, connector.
Embodiment
As shown in Figure 1, this Transformer Winding mould, comprise cylindricality winding mould, the winding mold sections is set as the oval mould that both sides are straight flange, as shown in Figure 2, the part of segmental arc up and down of mould is set as a groove structure with straight section 3 parts, the width setting of straight section 3 is lower than the segmental arc part, thereby form a groove, segmental arc and straight section 3 junctions are provided with connector 7 up and down, usually all be provided with the support plate 5 that supporting mould is used in the winding mould, the positive backward leading screw 6 that support plate 5 is provided with takes off ready-made coil windings to guarantee that this mould is convenient.The ground floor coil is near mould in winding process, when coil around behind certain size, the coil both sides just become straight line portion, have guaranteed the insulation distance between coil and the iron core; Advanced technique for coiling makes winding that higher dielectric strength be arranged, and the load loss of transformer is lower, and electric property is more reliable, and anti-short circuit capability is stronger.
Be respectively equipped with stiffener in last segmental arc 1 and the following segmental arc 2,, influence winding and use to guarantee that this mould can not be out of shape when coil windings is twined.
This Transformer Winding mould is by partly being provided with groove with straight section and arc section, make coil windings when twining, can not produce corner angle, but forming equally distributed loop construction, it is the coil windings of the elliptic cross-section of straight flange that this winding mould can be used for the coiling both sides specially.
Other contents of not describing are prior art, do not repeat them here.
Claims (2)
1. a Transformer Winding mould comprises cylindricality winding mould, it is characterized in that, described winding mold sections is set as the oval mould that both sides are straight flange, and the part of segmental arc up and down of mould is set as groove structure with straight section (3) part.
2. a kind of Transformer Winding mould according to claim 1 is characterized in that, is provided with stiffener (4) in the described up and down segmental arc.
