Abstract

The utility model relates to a vertical casting mold for a layer coil of a dry-type transformer. The mold comprises a bottom plate, an internal mold and an external mold; the internal mold is an integral cylinder; the external mold is a barrel which is provided with an opening which is axially protruded outwards and a folding-piece turnup; a cross section of the external mold is formed through the combining of a C-shaped circular arc curved surface section and an L-shaped straight-line section connected with the two ends of an arc; the opening of the folding-piece turnup of the external mold is provided with a tapping mold plate; the tapping mold plate, the internal mold and the external mold are arranged on the bottom plate; the internal mold is positioned in the external mold; and the internal mold is fixedly connected with the tapping mold plate. The vertical casting mold for the layer coil of the dry-type transformer of the utility model adopts the spatial structure, makes full use of the limited space among the windings of the dry-type transformer, has simple structure, is convenient for molding and demoulding and improves the production efficiency; in addition, the internal mold and the external mold adopt the integral structure, so that the vertical casting mold is easy to manufacture, avoids using more connecting pieces and saves the cost.

Description

The upright casting mold of dry-type transformer layer coil
Technical field
The utility model belongs to electrical equipment technical field, is specifically related to the upright casting mold of a kind of dry-type transformer layer coil.
Background technology
The high-tension coil of poured with epoxy resin type dry-type transformer be divided into paper tinsel around and wire-wound, the wire-wound high-tension coil is divided into laminar and cake formula again.Wire-wound high voltage layer type coil generally is flat watering, earlier that winding technique is good, refill mould and pour into a mould, carry out the suit of winding after cast is good again, and terminal place face is opened wide as the sprue gate during cast, wrap up in sheet metal outward and make mould, the coil two ends use steel plate to add the rubber slab sealing, and it is bigger that such mode takies casting space, is unfavorable for the raising of production efficiency, for improving this situation, we have designed the upright dress mould mode and the cast mould of coil.
The utility model content
The purpose of this utility model provides the upright casting mold of a kind of dry-type transformer layer coil, and the existing casting mold of solution takes up room greatly and the low problem of production efficiency.
For achieving the above object, the utility model adopts following technical scheme: the upright casting mold of a kind of dry-type transformer layer coil, this mould comprises base plate, internal mold and external mold, described internal mold is the integral type cylinder, external mold is that a place has outside axially outstanding opening and has the cylindrical shell of tabs flange, and its cross section is combined by the arc-shaped surface section of C type and the L type straightway that is connected on the circular arc two ends; The tabs flange opening part of described external mold is equipped with the tap template, and described tap template, internal mold and external mold all are located on the base plate, and internal mold is positioned at external mold, is mutually permanently connected between internal mold and the tap template.
Described base plate is provided with sealed rubber plate, and described tap template, internal mold and external mold all are located on the sealed rubber plate.
Fixedly connected by two connecting plates up and down between described internal mold and the tap template.
Described internal mold center is provided with core through screw rod, is provided with the fixed cross frame in internal mold, external mold upper end surface on the core through screw rod, and four ends of fixed cross frame are equipped with screw rod respectively, and each screw rod all is fixed on the base plate.
The upright casting mold of dry-type transformer layer coil of the present utility model adopts tridimensional structure, makes full use of the confined space between the dry-type transformer winding, and is simple in structure, adorns mould, is convenient in demoulding, and improved production efficiency; In addition, inside and outside mould adopts integral structure, makes easily, has avoided using more connector, has saved cost.

Embodiment
Below in conjunction with specific embodiment the utility model is done further introduction.
As Fig. 1~Figure 5 shows that structural representation of the upright casting mold specific embodiment of the utility model dry-type transformer layer coil, as seen from the figure, this mould comprises base plate 1, internal mold 2 and external mold 3, internal mold 2 is the integral type cylinder, external mold 3 is that a place has the outside axial cylindrical shell of giving prominence to opening and having the tabs flange, and its cross section is combined with the L type straightway that is connected on the circular arc two ends by the arc-shaped surface section of C type, the opening part of external mold is equipped with tap template 4, and the tap template is provided with tap stomidium 41.Tap template 4, internal mold 2 and external mold 3 all are located on the base plate 1, and internal mold 2 is positioned at external mold 3, fixedly connected by two connecting plates 5 up and down between internal mold and the tap template.
Internal mold of the present utility model and external mold adopt steel plate to make, and the tap template adopts aluminium material, and connecting plate adopts glass-cloth board, can adjust the distance between internal mold and external mold, the tap template, if be cast in the coil the inside, and also can be well bonding with epoxy resin.
As shown in Figure 5, base plate 1 is provided with sealed rubber plate 6, before the cast, coil stands upright on the base plate and sealed rubber plate of casting mold, at first install internal mold 2, with coil winding on internal mold, empty between each section of coil every putting resin mass 7 with no office, this resin mass is cast in the coil the inside, must guarantee no partial discharge, can ftracture with the good bonding nothing of epoxy resin simultaneously, support prevents from, then external mold and tap template are assemblied on the base plate, the junction of each parts uses clamping element to fix and seal, and from the upper end resin is injected base plate 1 then, internal mold 2, external mold 3, in the space that tap template 4 surrounds.Behind the casting complete, clamping element unclamps, and casting mold is broken.
As shown in Figure 1, when coiling and cast, for guaranteeing the balance of whole casting mold, the internal mold center is provided with core through screw rod 8, be provided with fixed cross frame 9 in internal mold, external mold upper end surface on the core through screw rod, four ends of fixed cross frame are equipped with screw rod 10 respectively, and each screw rod all is fixed on the base plate 1.The upright casting mold of dry-type transformer layer coil of the present utility model adopts tridimensional structure, makes full use of the confined space between the dry-type transformer winding, and is simple in structure, adorns mould, is convenient in demoulding, and improved production efficiency; In addition, inside and outside mould adopts integral structure, makes easily, has avoided using more connector, has saved cost.
