Abstract
The utility model discloses a transformer core comprising a core post (1) and a winding (2) arranged inside the core post (1). Both the core post (1) and the winding (2) are elliptical. A plurality of guide radiating plates (3) are fixed to both the inner surface of the core post (1) and the outer surface of the winding (2). Radiating passages (4) are formed among the guide radiating plates (3). Each guide radiating plate (3) is composed of a vertical plate (5) and a transverse plate (6) perpendicular to each other. The transformer core is optimally designed, the guide radiating plates are added, leakage magnetic field is less dense, no-load loss is reduced, and core temperature rise is decreased.
Description
Technical field
The utility model relates to field transformer, particularly relates to a kind of transformer core.
Background technology
Well-known transformer is widely used aborning, transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, iron core is the important component part in transformer, and existing iron core in use still exists the higher problem of iron core temperature rise.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of transformer core, by iron core optimal design, sets up guiding heat radiation plate, reduces stray field intensity, reduces no-load loss, reduces iron core temperature rise.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of transformer core is provided, comprise stem and winding, described winding is positioned at stem, described stem and winding are ellipse, the inner surface of described stem and the outer surface of winding are fixed with a plurality of guiding heat radiation plates jointly, between described each guiding heat radiation plate, form heat dissipation channel, and described guiding heat radiation plate is comprised of orthogonal riser and transverse slat.
In preferred embodiment of the utility model, the quantity of described guiding heat radiation plate is eight, is uniformly distributed.
In preferred embodiment of the utility model, the length of described riser is greater than transverse slat.
The beneficial effects of the utility model are: the utility model transformer core, by iron core optimal design, is set up guiding heat radiation plate, reduces stray field intensity, reduces no-load loss, reduces iron core temperature rise.
