Abstract
The utility model discloses a main pole iron core which comprises an iron core main body, three first screw holes, three second screw holes and a plurality of supporting feet. The first screw holes and the second screw holes are respectively formed in two sides of the iron core main body, and the supporting feet are arranged at the bottom end of the iron core main body. The main pole iron core reduces eddy-current loss and reduces temperature rise.
Description
Technical field
The utility model relates to a kind of iron core, particularly relates to a kind of main pole iron core.
Background technology
Iron core is the member with characteristics such as high initial permeability, low-loss and magnetic property are stable that soft magnetic material is made.Transformer core commonly used is generally all made of silicon steel sheet.Silicon steel is a kind of silicon steel of (silicon also claims silicon) that closes.The general iron core of all being made transformer by silicon steel is that in hot-wire coil, it can produce bigger magnetic flux density, thereby can make the volume-diminished of transformer because silicon steel itself is the very capable magnetisable material of a kind of magnetic conduction.Power loss in the iron core is " iron loss ", and iron loss is caused by two reasons, one be " magnetic hysteresis loss ", one is " eddy current loss ".Magnetic hysteresis loss be iron core in magnetization process, owing to the iron loss that exists hysteresis to produce, the size of this loss is directly proportional with the area size that magnetic hysteresis loop surrounded of material.The magnetic hysteresis loop of silicon steel is narrow and small, and the iron core magnetic hysteresis loss of making transformer of it is less, and its degree of heat is reduced greatly.But the iron core that existing silicon steel is made also exists this problem of eddy current loss to need to solve.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of main pole iron core, and it has reduced eddy current loss, has reduced temperature rise.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of main pole iron core, it is characterized in that, it comprises iron core main body, first screw hole, second screw hole, a plurality of leg, the quantity of the quantity of first screw hole, second screw hole all is three, first screw hole, second screw hole lay respectively at the both sides of iron core main body, and leg is positioned at the bottom of iron core main body.
Preferably, be provided with one the 3rd screw hole between described first screw hole, second screw hole.
Preferably, be provided with a groove between described adjacent two legs.
Positive progressive effect of the present utility model is: the utility model main pole iron core has reduced eddy current loss, has reduced temperature rise.
Description of drawings
Fig. 1 is the structural representation of the utility model main pole iron core.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model main pole iron core comprises iron core main body 1, first screw hole 2, second screw hole 3, a plurality of leg 5, the quantity of the quantity of first screw hole 2, second screw hole 3 all is three, first screw hole 2, second screw hole 3 lay respectively at the both sides of iron core main body 1, and leg 5 is positioned at the bottom of iron core main body 1.Can be provided with one the 3rd screw hole 4 between first screw hole 2, second screw hole 3.Be provided with a groove 6 between adjacent two legs 5.
The utility model main pole iron core makes eddy current in the leg of thin-and-long, by less cross section, thereby has reduced eddy current loss, has reduced temperature rise.First screw hole, second screw hole, the 3rd screw hole can be fixed with other elements, thus convenient the installation and the location.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
