Abstract

The utility model relates to a pouring mould of a transformer, which is characterized by consisting of an internal ring hoop and an external ring hoop that have the basically same structure, wherein both the internal ring hoop and the external ring hoop comprise steel plates (1) which encircle a circle; two ends of the steel plates (1) are bended and respectively form a left bend (1a) and a right bend (1b), wherein the left bend (1a) is welded with a left hoop (2), and the right bend (1b) is welded with a right hoop (3); and the left hoop (2) and the right hoop (3) are connected with each other by a bolt (4). The pouring mould has the remarkable advantages that the structure is simple, the pouring mould can be respectively used for pouring a low-voltage coil and a high-voltage coil on the whole, and the pouring and sealing demand of transformer coils with different sizes can be met.

Description

The transformer teeming mould
Technical field
The utility model belongs to technical field of transformer manufacturing, is a kind of transformer teeming mould that is used for the cast transformer coil specifically.
Background technology
Existing dry-type transformer, all be provided with low-voltage coil and high-tension coil, during installation, low-voltage coil is sleeved on the transformer core, again high-tension coil is sleeved on the low-voltage coil, and between iron core and low-voltage coil, increase insulation between the high and low pressure coil, be difficult to satisfy high and low pressure coil and the coil insulation distance between over the ground by traditional air insulation mode.For this reason, company begins to consider to low-voltage coil and high-tension coil encapsulated epoxy resin, make low-voltage coil and high-tension coil all become the global facility of independence and mutually insulated, so both can prevent to reach between the high and low pressure coil coil to the discharge between the iron core, also be convenient to the installation and the transportation of transformer.
But the shortcoming of prior art is: do not have a kind of casting mold rational in infrastructure, be difficult to carry out integrated poured to low-voltage coil and high-tension coil respectively.
The utility model content
The purpose of this utility model is to provide a kind of transformer teeming mould, can carry out integrated poured to the high and low pressure coil respectively.
To achieve these objectives, a kind of transformer teeming mould described in the utility model, its key is: be made up of inner ring anchor ear and outer ring anchor ear, wherein the inner ring anchor ear comprises steel plate, and this steel plate is encircled into a circle, and the two ends of described steel plate are bending in circle all, it is curved curved with right folding to form left folding respectively, be welded with left anchor ear on described left folding is curved, be welded with right anchor ear on described right folding is curved, described left anchor ear is connected by bolt with right anchor ear;
Described outer ring anchor ear is consistent with the structure of inner ring anchor ear, and its difference is: the two ends of described steel plate are bending outside circle all, and described left anchor ear, right anchor ear and bolt all are installed in outside the circle of outer ring anchor ear.
Inner ring anchor ear and outer ring anchor ear surround coil windings in the barrel of a cylindrical tube, behind the gap of epoxy resin embedding inlet wire circle winding, coil windings are shaped to a cylindrical structure that insulation effect is good.
Described left anchor ear is L-shaped, and an one flanging is connected with described left folding is curved, and another flanging has notch, and this notch is towards described right anchor ear;
Described right anchor ear is also L-shaped, and an one flanging and described right folding are curved to be connected, and another flanging is towards described left anchor ear, and stretches into the notch of described left anchor ear.
Left and right anchor ear is by the guiding of notch, and by the location of bolt realization to steel plate, the steel plates of different sizes can satisfy the embeddings of different big small coils.
Remarkable result of the present utility model is: a kind of transformer teeming mould is provided, and it is simple in structure, can be respectively low-voltage coil and high-tension coil is carried out integrated poured, simultaneously, can satisfy the embedding demands of different big primary transformer coils.
Description of drawings
Fig. 1 is the structural representation of inner ring anchor ear;
Fig. 2 is the assembly structure figure of left and right anchor ear;
Fig. 3 is the structural representation of outer ring anchor ear.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, 2, a kind of transformer teeming mould, form by inner ring anchor ear and outer ring anchor ear, wherein the inner ring anchor ear comprises steel plate 1, and this steel plate 1 is encircled into a circle, and the two ends of described steel plate 1 are bending in circle all, form curved 1a of left folding and the curved 1b of right folding respectively, be welded with left anchor ear 2 on the curved 1a of described left folding, be welded with right anchor ear 3 on the curved 1b of described right folding, described left anchor ear 2 is connected by bolt 4 with right anchor ear 3;
As shown in Figure 3, described outer ring anchor ear is consistent with the structure of inner ring anchor ear, and its difference is: the two ends of described steel plate 1 are bending outside circle all, and described left anchor ear 2, right anchor ear 3 and bolt 4 all are installed in outside the circle of outer ring anchor ear.
As shown in Figure 1, 2, 3, described left anchor ear 2 is L-shaped, and an one flanging is connected with the curved 1a of described left folding, and another flanging has notch, and this notch is towards described right anchor ear 3;
Described right anchor ear 3 is also L-shaped, and the curved 1b of an one flanging and described right folding is connected, and another flanging is towards described left anchor ear 2, and stretches into the notch of described left anchor ear 2.
Its operation principle is: coil windings, inner ring anchor ear and outer ring anchor ear are all put on the base of heating furnace, and inner ring anchor ear and outer ring anchor ear are placed with one heart, coil windings is placed in the gap between inner ring anchor ear and the outer ring anchor ear, tights a bolt 4, and locks with nut.After starting heating furnace heating ring epoxy resins and being fluid, again under vacuum state in the gap infusion epoxy resin, when epoxy resin the gap is filled full after.Remove vacuum then and will water injection molding and hang in the heating furnace and be heating and curing, cool off heating furnace at last, till the epoxy resin full solidification.Unclamp bolt 4 again, take inner ring anchor ear and outer ring anchor ear away, so just formed a coil that independently waters envelope.
The tap of low-voltage coil winding can be stretched out from the gap between inner ring anchor ear and the outer ring anchor ear, and the tap of the high-tension coil double-screw bolt of burn-oning is drawn by perforate on the steel plate 1.
