Abstract
The utility model relates to a transformer core. The periphery of the cross section of the core is formed by connecting four circular arcs, and the adjacent circular arcs of the four circular arcs are arranged in a mutually tangential way. Compared with the core with a long circle-shaped cross section, the radiation coefficient of the non-linear part is reduced to 1.05 to 1.08, the knocking is avoided when a coil is wound, and the defect of the coil caused by the knocking is reduced. Compared with the core with an elliptical cross section, the coil winding perimeter is shorter, and the core is more economical.
Description
Technical field
The utility model relates to transformer, relates in particular to a kind of transformer core.
Background technology
Generally there are three kinds of shapes in the cross section of existing distribution transformer and electrical transformer cores: circle, ellipse or Long Circle.Gloss obviously can't satisfy the needs that the coiling difference requires coil with the iron core of circular cross-section, and when iron core adopts long round section, the line part framing is not to docile during coil winding, design needs to consider that the bigger width of cloth is to coefficient (1.1 ~ 1.18), need beat during coiling, it is bigger that damaged probability is beaten in insulation; And when iron core adopted elliptic cross-section, the coil-winding girth was longer during coiling, and cost is higher, and the mould manufacture difficulty is big.
The utility model content
The purpose of this utility model is to provide a kind of transformer core, the periphery of the cross section of this iron core is that four arcs constitutes, can satisfy the coiling needs of different coils better, simultaneously, existing problem in the time of can avoiding adopting the iron core of oval and long round section again.
The technical solution of the utility model is as follows:
A kind of transformer core, the periphery of its cross section is formed by connecting by four arcs, and is tangent in twos between adjacent circular arc in the described four arcs.
Advantage of the present utility model is, compares with the iron core of long round section, and no line part framing reduces to 1.05 ~ 1.08 to coefficient, exempts to beat when realizing coil winding, reduces because beaing the coil defect that causes; Compare with the iron core of elliptic cross-section, the coiling girth is shorter, more economical.
Description of drawings

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
With reference to Fig. 1:
A kind of transformer core, the periphery of its cross section is formed by connecting by circular arc 1, circular arc 22, circular arc 33 and circular arc 44, and wherein, circular arc 1 is adjacent circular arc 22 and circular arc 44 is tangent respectively; The circular arc 22 that circular arc 33 also is adjacent and circular arc 44 are tangent respectively.
Claims (2)
1. a transformer core is characterized in that, the periphery of the cross section of this iron core is formed by connecting by four arcs.
2. a kind of transformer core according to claim 1 is characterized in that, and is tangent in twos between adjacent circular arc in the described four arcs.
