Abstract
The utility model relates to an amorphous alloy dry-type transformer coil and belongs to the technical field of amorphous alloy dry-type transformers. The amorphous alloy dry-type transformer coil is characterized in that the foil-wrapped coil is rectangular, and the rectangular foil-wrapped coil is cast into a steel integral structure through epoxy resin. The utility model has the advantages of simple structure, compactness in installation, convenience in assembly, economy and practicality, high product strength, saved transformer manufacturing cost, simplified assembly process, improved heat-dissipating capacity, strong short-circuit-prevention performance, etc.
Description
Technical field
The utility model belongs to the amorphous alloy dry-type transformer technical field, particularly relates to a kind of coil of amorphous alloy dry-type transformer.
Background technology
At present, existing amorphous alloy dry-type transformer, because the restriction of amorphous band, coil can only be designed to rectangular configuration, for paper tinsel around square coil, anti-short circuit capability is relatively poor, and conventional big capacity amorphous alloy dry-type transformer is taked to place the glass cloth tube between iron core and low-voltage coil, does to support between coil and glass cloth tube and improves anti-short circuit capability.Because the existence of glass cloth tube causes coil dimension bigger than normal, main material cost height, problems such as coil weak heat-dissipating.
Summary of the invention
The utility model provides a kind of coil of amorphous alloy dry-type transformer for solving the technical problem that exists in the known technology.
The purpose of this utility model provides a kind ofly to be had simple in structurely, installs compact, easy to assembly, economical and practical, the product strength height has been saved the transformer production cost, simplified assembling process, improved heat-sinking capability, the coil of amorphous alloy dry-type transformer of characteristics such as the product anti-short circuit capability is strong.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Coil of amorphous alloy dry-type transformer is characterized in: the paper tinsel coiling is a rectangle, and paper tinsel becomes a tempering structural entity around square coil by poured with epoxy resin.
The utility model can also adopt following technical scheme:
Described coil of amorphous alloy dry-type transformer is characterized in: paper tinsel insulate in there is the coiling of glass fiber grid cloth the square coil inboard, and there is glass fiber grid cloth coiling external insulation in the outside.
Advantage and the good effect that the utlity model has are:
Coil of amorphous alloy dry-type transformer is owing to adopted the utility model brand-new technology scheme, compared with prior art, coil of amorphous alloy dry-type transformer, at first turn to interior insulation with glass fiber grid cloth, secondly around amorphous alloy transformer coil, turn to external insulation with glass fiber grid cloth then, last coil after reaching specification requirement by relevant technology group mould, cast, curing.
The utlity model has simple in structure, install compact, easy to assembly, economical and practical, advantage such as the product strength height has been saved the transformer production cost, has simplified assembling process, has improved heat-sinking capability, and the product anti-short circuit capability is strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, insulating resin layer in the 1-, 2-amorphous alloy transformer coil, 3-external insulation resin bed.
Embodiment
For further understanding technology contents of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Consult accompanying drawing 1.
Embodiment 1
Coil of amorphous alloy dry-type transformer, its paper tinsel coiling 2 is a rectangle, paper tinsel becomes an integral body around square coil 2 by poured with epoxy resin, forms a tempering structure.
Paper tinsel is insulating resin layer 1 in there is the coiling of glass fiber grid cloth square coil 2 inboards, and there is glass fiber grid cloth coiling external insulation resin bed 3 in the outside.
The concrete assembly structure of present embodiment:
Coil of amorphous alloy dry-type transformer, at first turn to interior insulation with glass fiber grid cloth, secondly around amorphous alloy transformer coil, turn to external insulation with glass fiber grid cloth then, last coil after reaching specification requirement by technology group mould, cast, the curing of being correlated with.
The paper tinsel coiling is become an integral body with poured with epoxy resin, form a tempering structure, improved anti-short circuit capability greatly, replaced the glass cloth tube, make transformer device structure compact more, reduced overall dimension, saved production cost, improved efficiency.Owing to removed the support between coil and the glass cloth tube, effectively increased area of dissipation, improved the heat-sinking capability of coil.
