Abstract
The utility model discloses a kind of dry transformer high-tension coil horizontal type casting mold, including coil cast internal model, coil cast external mold, end positioning fixed supported slab, external mold liner plate, binding post fixed plate, coil cast internal model, coil cast external mold are horizontal, such a horizontal type casting mold is good because dissipating gas, cast is rapider, bubble is not likely to produce, reduces the partial discharge quantity of dry-type transformer, improves the operational reliability of dry-type transformer；Because not having to erect coil, reduce coil and collapse the possibility of line, product quality is relatively reliable, safer；The coil height poured can reach drawing requirement height, and end is smooth to be cut, without dust pollution, environmental protection；Because highly short, pouring can equipment funds input can be reduced, reduces cost.
Description
Technical field
Dry-Transformer Technology field is the utility model is related to, specially a kind of dry transformer high-tension coil horizontal type cast
Mould.
Background technology
For dry-type transformer compared with oil-filled transformer, dry-type transformer has the advantages of nonflammable explosive, and self-drying type becomes
Since depressor comes out, its capacity is increasing, the height of corresponding coil also more and more higher, and traditional vertical coil cast
Mould, vertical pouring is carried out by the sprue gate of coil end face, it is small because dissipating gas area, to prevent bubble, poring rate
Slowly, a defect when but pouring into a mould higher coil be present, coil cast does not complete also, and cast with epoxy resin
Increase through viscosity, Resin Flow is poor, so as to produce the problem of pouring into a mould easy outlet bubble；Simultaneously vertical pouring, exist coil because
The risk that line segment caused by standing up collapses；Mould one end of vertical pouring needs high-intensity sealing, a kind of coil mould of specification
Tool is all one-to-one pairing, it is impossible to which repetition is used other specification coil；, it is necessary to enter to upper surface after the completion of vertical pouring
Row polishing finishing, and dust pollution question can be produced；Vertical pouring needs the connection point terminal with coil cast external mold combination accessory
Fixed plate, it surrounds cast chamber outer wall, docking point terminal fixing plate volume, intensity, sealing jointly with coil cast external mold
Have higher requirements.
The content of the invention
To solve the above problems, the utility model provides a kind of dry transformer high-tension coil horizontal type casting mold, will
Vertical pouring device is changed to horizontal type casting mold, and cast is rapid, is not likely to produce bubble, reduces the shelf depreciation of dry-type transformer
Amount, improve the operational reliability of dry-type transformer；Reliable product quality is poured into a mould, end is smooth to be cut, no powder
Dustiness contaminates, environmental protection.
For achieving the above object, technical solution adopted in the utility model is：
A kind of dry transformer high-tension coil horizontal type casting mold, it includes coil cast internal model, coil cast external mold, end
Position fixed supported slab, external mold liner plate, binding post fixed plate, coil cast internal model, the cylinder that coil cast external mold is both ends open

With the branch wiring terminal fixed plate at center.
Described external mold liner plate is provided with stretching screw by hole, and its bracket arc and cast external mold are concentric, and bracket is to coil
Pour into a mould external mold and play picking-up supporting role.
The beneficial effects of the utility model are：
1. dry transformer high-tension coil horizontal type casting mold, outer die combination side is no longer poured into a mould using terminal plate and coil
Formula, but use to pour into a mould passage at binding post fixed plate, after using such a mode of connection instead, coil adds with extraneous contact area
Greatly, dissipate gas effect to be strengthened, poring rate can be accelerated in casting process, the cast of high coil is not completed also so as to solve,
Cast has occurred and that what viscosity declined with epoxy resin, poor permeability, the problem of being also easy to produce bubble；
2. such a casting mold does not have to erect coil, transport in whole whole production process coil, pour into a mould sidewards, can have
Effect reduces the risk that coil line segment because caused by standing up collapses, and product is more safe and reliable after cast.
3. coil cast external mold uses external mold liner plate to fix and strengthen jointly with end positioning fixed supported slab, in coil cast
Sealed between mould, coil cast external mold and end positioning fixed supported slab with U-shaped rubber strip, rubber strip is repeatable to be utilized, compared to tradition
Upright pouring die has saved the cost of glass for sealing glue；
4th, dry-type transformer horizontal type casting mold, can be on the basis of original pouring can equipment to Large Copacity because highly short
Transformer coil is poured into a mould, and double-deck pouring can be carried out to the coil of miniature transformer, so as to reduce the money of pouring can equipment
Gold input.
5. after carrying out casting complete by the present apparatus, as high-tension coil after the epoxy resin surface solidification trickled naturally
Patch panel, coil height disposably reaches requirement for height after cast, it is not necessary to coil of polishing, saving manpower, and without dust pollution,
Effectively increase the cast efficiency of mould.
