Abstract
A transformer iron core belongs to transformer iron cores, and mainly solves the problem that the magnetic flux density of a common transformer iron core is not easy to be changed. The transformer iron core comprises an iron core stacked by core posts with a stepped cross section, the thickness of the first core post in the center of the iron core is 63%-74% of the total thickness of iron core, and the step-shaped core posts are stacked into an iron core with an ellipsoidal cross section for reducing the cost of a coil winding. The transformer iron core is provided with the first core post with adjustable thickness, thereby effectively solving the problem that the magnetic flux density of the transformer iron core is not easy to be changed. As the cross section of the iron core is an ellipsoidal structure, the transformer iron core effectively reduces cost of the coil winding, has simple structure and is suitable for mass production.
Description
Technical field
The utility model relates to a kind of iron core of transformer.
Background technology
In present transformer Electromagnetic Design, the iron core of most of transformer all is designed to cylindrical laminated structure, form by the silicon steel sheet stack, because during the traditional fabrication transformer, Step Circular is adopted in stem stem cross section unshakable in one's determination, its stem stem the fixing formula of diameter utilization calculate, all fix according to the iron core that formula calculates, the magnetic flux density of stem stem is by the number of turn decision that is wrapped in its outside winding, magnetic flux density is crossed conference makes higher harmonic components unshakable in one's determination bigger, transformer is produced very big influence, if change the magnetic flux density of stem stem, must change winding and be wrapped in the number of turn on the stem stem, will change its number of turn after winding is installed must change again, both wasted time and energy, waste material increases cost again.
The utility model content
The problem that is not easy to change at the magnetic flux density of existing transformer core, the utility model provides a kind of novel transformer core, it is by being provided with the stem stem of adjustable thickness, reach adjusting to magnetic flux density unshakable in one's determination, thereby reduce higher harmonic components, reduce noise, reduce no-load loss, increase the conversion of electric energy.
The concrete technical scheme that the utility model adopts is: a kind of transformer core, comprise the iron core that be piled into for the notch cuttype stem stem in the cross section, it is characterized in that, described center unshakable in one's determination is provided with removable first stem stem, the thickness of first stem stem is made as the 63%-74% of total folded thickness unshakable in one's determination, stem stem all adopts high magnetic conduction high-quality grain orientation cold-reduced silicon sheet to make, adopt 45 degree full bias seams, choosing by core section of the first stem stem thickness converts, the optimum thickness of its first stem stem should be total folded thick 63%-74% unshakable in one's determination, the thickness of first stem stem is made as adjustable, can regulate magnetic flux density by the thickness of regulating first stem stem.
After coil windings is determined, can regulate first stem stem unshakable in one's determination and reduce magnetic flux density unshakable in one's determination, lower magnetic flux density makes the higher harmonic components that produces in the iron core less, and therefore the flexible noise intensity that is produced of the silicon steel sheet magnetic hysteresis that causes can reduce, and has reduced no-load loss; Unshakable in one's determination through making transformer in running, avoid getting rusty after the special processing again.
Described core section is made as ellipsoidal structure, and winding is provided with and corresponding ellipsoidal structure unshakable in one's determination, is piled into the iron core of elliptic cross-section by the notch cuttype stem stem, can reduce the cost of coil windings.
The beneficial effects of the utility model are: this transformer core is by being provided with first stem stem of adjustable thickness, efficiently solve the not problem of malleable of transformer core magnetic flux density, reduce magnetic flux density unshakable in one's determination by regulating first stem stem, lower magnetic flux density makes the higher harmonic components that produces in the iron core less, therefore the flexible noise intensity that is produced of the silicon steel sheet magnetic hysteresis that causes can reduce, reduced no-load loss, cross section unshakable in one's determination is an ellipsoidal structure, effectively reduced the use cost of coil windings, simple in structure, be suitable for large-scale production.
Description of drawings
Accompanying drawing 1 is a cross section structure schematic diagram of the present utility model.
The 1st, unshakable in one's determination, 2 is first stem stems.
Embodiment
As shown in Figure 1, this transformer core, comprise the iron core 1 that be piled into for the notch cuttype stem stem in the cross section, 1 center unshakable in one's determination is provided with removable first stem stem 2, the thickness of first stem stem 2 is made as the 63%-74% of unshakable in one's determination 1 total folded thickness, can in this scope, regulate the thickness of first stem stem, stem stem all adopts high magnetic conduction high-quality grain orientation cold-reduced silicon sheet to make, adopt 45 degree full bias seams, after coil windings is determined, first stem stem 2 that can regulate iron core 1 reduces magnetic flux density unshakable in one's determination, and lower magnetic flux density makes the higher harmonic components that produces in the iron core less, and therefore the flexible noise intensity that is produced of the silicon steel sheet magnetic hysteresis that causes can reduce, reduced no-load loss, core section is made as ellipsoidal structure, is piled into the iron core of elliptic cross-section by the notch cuttype stem stem, can reduce the cost of coil windings.
This transformer core is by being provided with adjustable thickness first stem stem, the magnetic flux density that efficiently solves transformer core is the problem of malleable not, reduce magnetic flux density unshakable in one's determination by regulating first stem stem, lower magnetic flux density makes the higher harmonic components that produces in the iron core less, therefore the flexible noise intensity that is produced of the silicon steel sheet magnetic hysteresis that causes can reduce, reduced no-load loss, cross section unshakable in one's determination is an ellipsoidal structure, effectively reduced the use cost of coil windings, simple in structure, be suitable for large-scale production.
What other contents of not describing adopted is prior art, does not repeat them here.
