Abstract
The utility model relates to a dry type transformer, in particular to a high tension coil structure of an epoxy resin cast dry type transformer, which comprises epoxy resin, electromagnetic wires and fiber glass gridding cloth. The structure is characterized in that the fiber glass gridding cloth with holes is formed between layers of the electromagnetic wires; holes with identical specifications and sizes are uniformly distributed on the fiber glass gridding cloth; and square holes with identical specifications and sizes are uniformly distributed on the fiber glass gridding cloth. The structure ensures that the epoxy resin can be completely impregnated into the inner part of a coil when the high tension coil is cast, the local discharge capacity is reduced, and the service life of the transformer is prolonged.
Description
Technical field
The utility model relates to a kind of dry-type transformer, is specifically related to a kind of structure of poured with epoxy resin dry-type transformer high-tension coil, belongs to the electric equipment field.
Background technology
Poured with epoxy resin dry-type transformer high-tension coil generally adopts insulating material such as DMD insulating papers more at present, because the non-constant of this type of insulating material impregnability, itself and epoxy resin are immiscible, resin can't soak into coil in whole casting process, therefore the every layer conductor of high pressure winding is almost completely isolated, thereby the local electric weight of high-tension coil is increased, influence the useful life of transformer.
Summary of the invention
The purpose of this utility model provides a kind of structure of poured with epoxy resin dry-type transformer high-tension coil, it makes poured with epoxy resin dry-type transformer high-tension coil epoxy resin when cast can be impregnated into coil inside fully, reduce the partial discharge quantity of transformer, improved the useful life of transformer.
Technical solutions of the utility model are: a kind of structure of poured with epoxy resin dry-type transformer high-tension coil, it comprises epoxy resin, electromagnetic wire, glass fiber grid cloth, it is characterized in that: the interlayer of electromagnetic wire has glass fiber grid cloth with holes.
Be evenly distributed with the identical hole of specification size on the described glass fiber grid cloth.
Be evenly distributed with the identical square hole of specification size on the described glass fiber grid cloth.
The utility model has the advantages that: owing to replaced the DMD insulating paper of common usefulness with glass fiber grid cloth, wherein glass fiber grid cloth is between the electromagnetic wire, because the identical square hole of specification size is arranged in the middle of the glass fiber grid cloth, high-tension coil is in casting process like this, and the square hole that epoxy resin can soak into glass fiber grid cloth fully is cast on the electromagnetic wire.Make high-tension coil can soak into whole winding fully in casting process, it is as a whole that whole winding becomes, and greatly reduces the partial discharge quantity of transformer like this, improved the mechanical strength of transformer, increased the useful life of transformer.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, epoxy resin; 2, electromagnetic wire; 3, glass fiber grid cloth.
Embodiment
Embodiment 1: as shown in Figure 1, it comprises epoxy resin 1, electromagnetic wire 2, glass fiber grid cloth 3, and glass fiber grid cloth 3 is characterized in that as the layer insulation of electromagnetic wire 2: the interlayer of electromagnetic wire 2 has glass fiber grid cloth 3 with holes.
Embodiment 2: and embodiment 1 is basic identical, and institute is not both and is evenly distributed with the big or small identical hole of specification on the glass cross lattice cloth 3.The hole can be a square hole, also can be elliptical aperture.
Therefore epoxy resin 1 is easy to be penetrated on the electromagnetic wire 2 of winding arranged side by side by glass fiber grid cloth 3.Transformer coil inside is soaked into fully, 2 one-tenth in electromagnetic wire is as a whole in the transformer coil, and owing to there is glass fiber grid cloth 3 in whole winding, to play booster action, the transformer coil bulk strength is greatly improved, reduce the partial discharge quantity of transformer, increased the useful life of transformer.The structure of this poured with epoxy resin dry-type transformer high-tension coil, glass fiber grid cloth 3 and electromagnetic wire 2 closely are intertwined.
