Description
Technical field
The utility model discloses a kind of dry-type transformer three-dimensional rolled iron core, specially power equipment technology is led
Domain.
Background technology
Transformer is the device for converting alternating voltage, electric current and impedance, when being connected with alternating current in primary coil, iron core
Exchange flux is just generated in (or magnetic core), makes to induce voltage (or electric current) in secondary coil.Transformer is by iron core (or magnetic core)
Formed with coil, coil there are two or more than two windings, wherein connect the winding of power supply primary coil, remaining winding
Secondary coil.In generator, either coil movement by magnetic field or Movement in Magnetic Field by fixed coil, can be in coil
Induced potential, this two kinds of situations, the value of magnetic flux is constant, but has variation with the magnetic flux quantity of coil intersecting chain, this is mutual inductance
The principle answered.Transformer is exactly a kind of utilization undesirable mutual electromagnetic inductance effect, voltage of transformation, the device of electric current and impedance.Existing transformation
Its efficiency of the irony winding of device is low, iron space factor is low, magnetic resistance is big.For this purpose, we have proposed a kind of dry-type transformers with three
Dimension three dimensional wound core comes into operation, to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of dry-type transformer three-dimensional rolled iron cores, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides the following technical solutions：A kind of dry-type transformer is rolled up with 3 D stereo
Iron core, including about two groups mounting brackets disposed in parallel are vertically equipped with inserted sheet iron core between mounting bracket described in two groups, and insert
The mounting bracket being located above is run through at the top of piece iron core and used screw-nut is fixedly connected with the surface of mounting bracket, described
The left and right sides of inserted sheet iron core is equipped with iron core, and iron core is located between two groups of mounting brackets, according to side clockwise on the iron core
Formula uniform winding has metal material belt, the left and right ends of the mounting bracket to be additionally provided with fixed plate.
Preferably, the iron core is equipped with three groups, and three groups of iron core arrangements in equilateral triangle.
Preferably, the section of the metal material belt is isosceles trapezoidal structure.
Preferably, the iron core is semicircular structure, and the cross section of the metal material belt on three groups of iron cores is close to circle
Quasi- polygonized structure.
Compared with prior art, the utility model has the beneficial effects that：Three groups of iron cores winding of the utility model is compacted, iron
The fill factor of core is high, and magnetic resistance is small, and the continuous winding of metal material belt can ensure that magnetic conduction direction is consistent with actual magnetic flux direction.

The heart, including about two groups mounting brackets 1 disposed in parallel are vertically equipped with inserted sheet iron core 2 between mounting bracket 1 described in two groups, and
The mounting bracket 1 being located above is run through at the top of inserted sheet iron core 2 and the surface of used screw-nut and mounting bracket 1 is fixed and connected
It connects, the left and right sides of the inserted sheet iron core 2 is equipped with iron core 3, and iron core 3 is located between two groups of mounting brackets 1, on the iron core 3
There are metal material belt 4, the left and right ends of the mounting bracket 1 to be additionally provided with fixed plate 5 according to clock-wise fashion uniform winding.
Wherein, the iron core 3 is equipped with three groups, and three groups of 3 arrangements in equilateral triangle of iron core, and the metal material belt 4 is cut
Face is isosceles trapezoidal structure, and the iron core 3 is semicircular structure, and the cross section of the metal material belt 4 on three groups of iron cores 3 is close
Circular quasi- polygonized structure.
Operation principle：Using fixed plate 5 by the present apparatus be mounted on dry-type transformer in, by three groups of iron cores 3 uniformly not between
The metal material belt 4 of disconnected winding, enables the induced potential in coil of iron core 3, and three groups of 3 arrangements in equilateral triangle of iron core, really
The mean value for protecting magnetic flux is constant, and generates the mutual induction of electromagnetism, and magnetic conduction direction is consistent with actual flow direction, the present apparatus
