Abstract
The utility model relates to a novel energy-conserving power transformer of dry-type has adopted the insulating casing structure, and the coil is placed in the insulating casing, has inlayed the insulator between the obvious space of coil and insulating casing, through epoxy pouring and solidification, makes epoxy and coil and insulating casing constitute an organic whole. The insulating shell consists of an outer wall, an inner wall, a shell bottom and a plurality of wire outlet terminals, and the opening of the insulating shell faces upwards. The insulating shell is made of electrical insulating paper boards or electrical insulating rubber boards, and can also be made of engineering plastics or glass fiber reinforced plastic materials by die pressing. It has reasonable structure and low cost.
Description
The utility model relates to a kind of general power transformer, particularly a kind of novel dry type energy-saving power transformer.
As everyone knows; along with electric load develops to intensity; requirement for the visual plant power transformer of electric power transfer is more and more stricter; realize the reliability service of safety nothing combustion in order to make power transformer; people develop the dry-type power transformer that substitutes oil-immersed type transformer; the kind of the dry-type power transformer that has come into operation at present is more; coil category division by its use; the impregnated coil is arranged; aluminium foil or poured with epoxy resin coil; Copper Foil formula poured with epoxy resin coil; also has the aluminum steel formula; copper cash formula poured with epoxy resin coil; and epoxy resin thin layer molded coil; epoxy resin enclosed coil; it is reported; the coil of above-mentioned poured with epoxy resin; complex process not only; and when cast is for the solid shape of the epoxy resin of auxiliary cast; need a large amount of metal dies; behind epoxy resin cure, also need slough metal die through the coil behind the poured with epoxy resin; time-consuming like this; make that coil cost cost is very high; many producers are in order to realize the continuous productive process of coil processing resene cast; introduce expensive production line toward contact; the cost of dry-type power transformer is further increased, and the characteristic of epoxy resin itself on the other hand is when the epoxy resin unprotect of having solidified is outer; the ambient temperature that does not often adapt to hurried variation; cause the finished product coil to be prone to crack performance, thereby reduce coil insulation, the serious whole winding that makes is scrapped.
The purpose of this utility model is, at above-mentioned the deficiencies in the prior art, under the prerequisite of the coil electric performance that does not change existing poured with epoxy resin encapsulation, existing dry-type power transformer improved, and proposes a kind of novel dry type energy-saving power transformer.
Technical solution of the present utility model is, coil for poured with epoxy resin is arranged, it is characterized in that, adopted insulation shell, coil is placed in the insulation shell, between the obvious space of coil and insulation shell, be embedded with insulant,, make epoxy resin and coil and insulation shell formation one by poured with epoxy resin and being solidificated in the insulation shell.Insulation shell by outer wall, inwall, shell at the bottom of and a plurality of outlet terminal form, it is as a whole that inwall, outer wall are connected, the opening of insulation shell up, a plurality of outlet terminals are on the outer wall of insulation shell.Insulation shell is by electric insulation cardboard or electric insulation offset plate processing and fabricating.Insulation shell can also be made by engineering plastics, fiberglass or other electrical insulating material mold pressing.
The utility model has the advantages that; use insulation shell substituted metal mould; both as the disposal pouring mould; conduct is by the containment vessel of molded coil again; make processing pouring forming technology process simplify; saved traditional knockout course; thereby reduced production cost; energy savings again; have certain force of strain and tensile resistence as the insulation shell of coil protect shell because of the characteristic of its manufacturing materials on the other hand; thereby the cast of protection coil; be full of cracks and deformation do not take place in the rapid variation that the encapsulant epoxy resin cure can stand ambient temperature; improve the qualification rate that manufactures a finished product; guarantee the coil insulation performance, be embedded with the anti-crack ability that insulant and long fibre can improve the epoxy resin cure body simultaneously in the space of casting epoxy resin, can also suitably reduce the consumption of epoxy resin; cost is reduced; therefore the utility model is economical and practical, reasonable in design, the difformity of insulation shell; can improve the profile of coil, make it variation.

Below, embodiment of the present utility model is described with reference to the accompanying drawings.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is made up of insulation shell 1, epoxy resin 2, coil 3, insulant 4, coil 3 is inserted in the insulation shell 1, between the obvious space of coil 3 and insulation shell 1, be embedded with insulant 4, by poured with epoxy resin and curing, make the epoxy resin 2 after the curing constitute a complete integral body with coil 3 and insulation shell 1, insulant 4 is the insulating material of long fibre or hard, and good insulation preformance has stretch-proof ability and certain force of strain.The insulating material of hard can be processed into fragment and chip, mix at the epoxy resin 2 that will pour into a mould as inserts, insulation shell 1 by outer wall 8, inwall 6, shell at the bottom of 7 and a plurality of outlet terminal 5 form, 7 are connected as a single entity inwall 6, outer wall 8 at the bottom of the shell, can be one by bonding and mold pressing.Leave certain space between inwall 6 and the outer wall 8 for putting coil 3 and casting epoxy resin 2 usefulness.The opening of insulation shell 1 up, a plurality of outlet terminals 5 are arranged in respectively on the outer wall 8 of insulation shell 1, a plurality of outlet terminals 5 can be processed separately, bond on the outer wall 8 again, also can make with other one that forms insulation shell 1 integral die together.The fragment and the chip that are cast in the insulant 4 that mixes in the epoxy resin 2 in the insulation shell 1 have certain ratio, not influence the epoxy encapsulation solidification effect, reduce the consumption of epoxy resin 2 under the every electric index of assurance coil 3 and the prerequisite of insulating properties thereof, the manufacturing materials of a plurality of outlet terminals 5 is identical with the material of the other parts of insulation shell 1, also can make separately of other electrical insulating material, insulation shell 1 is a basic module of the present utility model, it is again disposable cast mould, insulation shell 1 uses electrical insulation board or bonding the forming of electrician's glue art plate processing and fabricating, insulation shell 1 can also be used engineering plastics, fiberglass or other electrical insulating material mold pressing are made, one-shot forming.
As Fig. 5, Fig. 6, provided a kind of columnar the utility model component insulation shell 1 example, basic structure is identical with aforesaid insulation shell 1, just outer deformation, specification according to coil is different with shape, and we can also be designed to rhombus or rectangle or square structure to insulation shell 1.
