Abstract
A foil winding structure of a low-voltage coil comprises a hollow cylindrical foil winding coil (1), a copper-row or aluminium-row head end (X) positioned in the foil winding coil (1), and a copper-row or aluminium-row tail end (A) positioned outside the foil winding coil (1), wherein the head end (X) and the tail end (A) are bent to form the radian the same as that of the inner diameter or the outer diameter of the foil winding coil (1). The foil winding structure overcomes the disadvantages such as two asymmetrical edges of an iron core caused by short mechanical distance between the prior foil type coil and the iron core. The utility model improves space utilization rate of the foil winding coil, and has the advantages of symmetrical iron core distribution, more uniform electric field distribution, more compact structure, simple manufacture and convenient use.
Description
Technical field
The utility model relates to parts on the transformer, and more particularly it is that a kind of low-voltage coil paper tinsel is around structure.
Background technology
Foil coil is because its Electric Field Distribution is even, and compact conformation, anti-short circuit capability are widely used in by force in the low-voltage coil, and its techno-economic effect is obvious in 630kVA and above distribution transformer especially.
The coil leading-out end of existing foil coil (having comprised the head and tail head) adopts copper bar mostly, its traditional structure foil coil (as shown in Figure 1), start X and the tail head A of coil draw from coil inner surface and outer surface respectively, since be the square-section they all need to occupy certain locus, internally cause with the mechanical distance of iron core not enough, need reduce lamination or remove minimum level at leading-out terminal, thereby make the iron core both sides asymmetric; External ledge causes with the electric insulation distance of high-tension coil not enough, needs the distance between adjustment or the increasing high-low pressure.Dry-type transformer also needs the Mould Machining size that becomes adapt is made difficulty, and manufactured size is difficult for guaranteeing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned existing disadvantages of background technology part, and provides a kind of low-voltage coil paper tinsel around structure.
The purpose of this utility model reaches by following measure: the low-voltage coil paper tinsel is around structure, it comprises cylinder paper tinsel coiling empty in, be positioned at the copper bar or the aluminium row head end of paper tinsel coiling, outer copper bar or the aluminium last person head with being positioned at the paper tinsel coiling, it is special to be that described head end and tail head are bent into internal diameter or the external diameter identical radian measure with the paper tinsel coiling.
The utility model low-voltage coil paper tinsel has following advantage around structure: improve space availability ratio, can save material; Iron core is distributed symmetrically, makes more even, the more compact structure of Electric Field Distribution; Make simple, easy to use.
Description of drawings
Fig. 1 is for having the low-voltage coil paper tinsel now around structural representation.
Fig. 2 is that the utility model low-voltage coil paper tinsel is around structural representation.
1 is the paper tinsel coiling among the figure, and X head end (copper bar or aluminium row), A are tail head (copper bar or aluminium row).
Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to qualification of the present utility model, only do for example.Simultaneously by illustrating that advantage of the present utility model will become clear more and understanding easily.
Consult Fig. 2 as can be known: the utility model low-voltage coil paper tinsel is around structure, it comprises cylinder paper tinsel coiling 1 empty in, be positioned at the copper bar or the aluminium row head end X of paper tinsel coiling 1, with the copper bar or the aluminium last person A that are positioned at outside the paper tinsel coiling 1, described head end X and tail head A are bent into internal diameter or the external diameter identical radian measure with paper tinsel coiling 1.
Claims (1)
1, the low-voltage coil paper tinsel is around structure, it comprises cylinder paper tinsel coiling (1) empty in, be positioned at the copper bar or the aluminium row head end (X) of paper tinsel coiling (1), outer copper bar or the aluminium last person head (A) with being positioned at paper tinsel coiling (1), it is special to be that described head end (X) and tail head (A) are bent into internal diameter or the external diameter identical radian measure with paper tinsel coiling (1).
