Description
Technical field
This utility model relates to dry-type transformer coil field, particularly to a kind of dry-type transformer coil
The shaped device of cast.
Background technology
In the manufacture process of epoxy resin dry type transformer, need with epoxy resin fix coil around
Group.The coil windings of each transformator will casting epoxy resin, due to the epoxy resin of vacuum pouring
Being liquid body, the coil of casting complete is when performing curing process operation, and epoxy resin solidifies receipts gradually
Contracting, causes coil height step-down, the shaped device then needing coil to pour into a mould to make improvements.
Utility model content
The purpose of this utility model is to provide for a kind of dry-type transformer coil shaped device, solves and waters
Note coil curing process epoxy resin solidification shrinkage causes the technical problem of coil height step-down.
According to an aspect of the present utility model, it is provided that a kind of dry-type transformer coil shaped device,
Including casting mold and coil, casting mold includes die body, inner ring plate, outer ring plate, and inner ring plate is with outer
Ring flat-plate is built in die body with one heart, and inner ring plate is closed circular, and outer ring plate is fixed bar by outer spill and connected
Becoming closed-loop, coil is built between inner ring plate, outer ring plate the toroidal cavity formed, the end face of die body
Being communicated with resin-cast hole and the resin charging aperture of toroidal cavity, the side of die body is communicated with annular
Cavity and for control cast height spout hole.
Owing to coil curing process can complete epoxy resin charging process by resin charging aperture, because of
This efficiently avoid epoxy resin solidification shrinkage gradually and causes the phenomenon of coil height step-down.
In some embodiments, the bottom surface of die body is provided with base plate, and inner ring plate, outer ring plate are mounted on
Base plate.Thus, inner ring plate, outer ring plate can consolidate the bottom surface being fixed on die body, it is ensured that poured into a mould
The stability of journey.
In some embodiments, inner ring plate, outer ring plate are all in elliptical ring.Thus so that poured into a mould
Journey epoxy resin can be poured into a mould equably.
This utility model simple in construction, saves material, substantially increases production efficiency, and reduce life
Produce cost.
Accompanying drawing explanation
Fig. 1 is the schematic front view of this utility model one embodiment dry-type transformer coil shaped device；
Fig. 2 is the schematic top plan view of dry-type transformer coil shaped device shown in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in further detail by embodiment.
As shown in Figure 1, 2, this dry-type transformer coil shaped device includes casting mold 1 and coil 2,
Casting mold 1 includes die body 11, inner ring plate 12, outer ring plate 13, and inner ring plate 12, outer ring plate 13 are equal
In elliptical ring, the bottom surface of die body 11 is provided with base plate 14, and inner ring plate 12, outer ring plate 13 are mounted on the end
Plate 14, inner ring plate 12 be built in die body 11 concentric with outer ring plate 13, inner ring plate 12 in closed circular,
Outer ring plate 13 is fixed bar 15 by outer spill and is connected into closed-loop, and coil 2 is built in inner ring plate, outer
The toroidal cavity 3 formed between ring flat-plate, the end face of die body 11 is communicated with the resin of toroidal cavity 3 and waters
Orifice 4 and resin charging aperture 5, the side of die body 11 is communicated with toroidal cavity 3 and waters for control
The spout hole 6 of note height.
Casting mold 1, according to the height dimension of coil 2 pour mass, arranges spout hole, at coil 2 ring
During epoxy resins vacuum pouring, it is accurately controlled the height of poured with epoxy resin, due to vacuum pouring
Epoxy resin be liquid body, the coil 2 of casting complete perform curing process operation time, asphalt mixtures modified by epoxy resin
Fat solidification shrinkage gradually, causes coil 2 height step-down, and above-mentioned shaped device arranges resin charging aperture 5,
I.e. add epoxy resin charging link, i.e. when coil 2 curing process starts, according to technological procedure
Carry out curing operation after 9 hours, open baking oven and coil 2 is carried out epoxy resin charging, fed
Continue executing with coil 2 curing operation after one-tenth, efficiently avoid epoxy resin solidification shrinkage gradually and lead
The phenomenon of induced coil 2 height step-down, saves material, substantially increases production efficiency, and reduce life
Produce cost.
Above-described is only embodiments more of the present utility model.Ordinary skill for this area
For personnel, on the premise of creating design without departing from this utility model, it is also possible to make some deformation
And improvement, these broadly fall into protection domain of the present utility model.
