Abstract
A kind of winding mould of dry-type transformer low pressure winding, comprise two be arranged in parallel for winding around supporting bracket and be fixed on the end plate at two supporting bracket two ends respectively by fastening bolt, the end plate at supporting bracket two ends is the oval plate-like piece that structure is identical, and the projection on end plate of its major axis and supporting bracket parallels, on the outline that oval end plate is relative with major axis, symmetry offers two zygonema mouths, and on the outline that oval end plate is relative with minor axis, symmetry offers two busbar export mouths; The middle part of described end plate is provided with winding shaft bore.The utility model forms the supporting mould of winding by arranging end plate at supporting bracket two ends, on end plate, then offer busbar export mouth and zygonema mouth adjust the gap between the coil forming winding, thus avoid the problem that the transformer that causes because coil winding density is unreasonable reduces useful life.
Description
Technical field
The utility model relates to dry-type transformer field, specifically a kind of winding mould of dry-type transformer low pressure winding.
Background technology
Dry-type transformer relies on cross-ventilation to cool, and be generally used for localized lighting, electronic circuit, its iron core and winding are not immersed in insulating oil.Dry-type transformer has two windings, and what voltage was higher is high pressure winding, and lower is low pressure winding, and winding has coil to be wound.When coiling winding, generally that coil winding is carried out coiling on mould, after completing, namely taking-up mould obtains the winding that coiling completes, but existing mould is just played a supporting role, during coiling, often cause there is gap between coil, cause the quality of winding and useful life not high like this.
Utility model content
For when solving coiling winding in prior art due to exist between coil gap cause winding quality and useful life difference problem, the utility model provides a kind of winding mould of dry-type transformer low pressure winding.
The utility model is the technical scheme solving the problems of the technologies described above employing: a kind of winding mould of dry-type transformer low pressure winding, comprise two be arranged in parallel for winding around supporting bracket and be fixed on the end plate at two supporting bracket two ends respectively by fastening bolt, the end plate at described supporting bracket two ends is the oval plate-like piece that structure is identical, and the projection on end plate of its major axis and supporting bracket parallels, on the outline that oval end plate is relative with major axis, symmetry offers two zygonema mouths, on the outline that oval end plate is relative with minor axis, symmetry offers two busbar export mouths, be arc male part between adjacent busbar export mouth and zygonema mouth, the middle part of described end plate is provided with winding shaft bore.
The bottom of described busbar export mouth is arc protruding laterally.
In the utility model, two described supporting brackets form the support of coiling winding, concordant with supporting bracket surface bottom the zygonema mouth on end plate, to use the gap of external force by zygonema mouth adjustment coiling; Described busbar export mouth is convenient to be connected with the coil interface forming winding in the good winding of busbar insertion coiling.
Beneficial effect: the utility model forms the supporting mould of winding by arranging end plate at supporting bracket two ends, on end plate, then offer busbar export mouth and zygonema mouth adjust the gap between the coil forming winding, thus avoid the problem that the transformer that causes because coil winding density is unreasonable reduces useful life.

Embodiment
As shown in the figure, a kind of winding mould of dry-type transformer low pressure winding, comprise two be arranged in parallel for winding around supporting bracket 2 and be fixed on the end plate 1 at two supporting bracket 2 two ends respectively by fastening bolt 3, the edge of supporting bracket 2 has the gradient of circular arc, to prevent from scratching coil, the end plate 1 at supporting bracket 2 two ends is the oval plate-like piece 101 that structure is identical, and its major axis parallels with the projection of supporting bracket 2 on end plate 1, on the outline that oval end plate 1 is relative with major axis, symmetry offers two zygonema mouths 102, the bottom of two zygonema mouths 102 is mutually concordant with the plate face of two supporting brackets 2, on the outline that oval end plate 1 is relative with minor axis, symmetry offers two busbar export mouths 104, the bottom of busbar export mouth 104 is arc protruding laterally, be arc male part 105 between adjacent busbar export mouth 104 and zygonema mouth 102, the middle part of described end plate 1 is provided with winding shaft bore 103.
The utility model in use, fastening bolt 3 is used two supporting brackets 2 and two end plates 1 to be assembled, then the one end along supporting bracket 2 starts coiling, a joint of coil is in the position of busbar export mouth 104 so that be connected with busbar, adjusted by the winding space that zygonema mouth 102 is good to coiling in the process of coiling, after coiling, two busbars are connected respectively with two joints of coil, and then busbar is inserted in winding coil by busbar export mouth 104, twisting off fastening bolt 3 makes end plate 1 be separated with supporting bracket 2, supporting bracket 2 is taken out from winding.
