The transformer iron core is characterized in that each iron core unit is spliced into a shape like the Chinese character 'ri' by two sets of iron yoke units and three sets of stem units, and junctures between the iron yoke units and the stem units are 45 degrees. The transformer iron core is low in processing cost and lower in loss.
Description
Technical field
The utility model relates to a kind of transformer, specifically a kind of transformer core.
Background technology
Generally speaking, transformer work under exchange status always, power loss not only on the resistance of coil, also is created in the iron core under the alternating current magnetization., there is alternating current in transformer when work in the coil, the magnetic flux that its produces yes alternation.The magnetic flux of this variation produces induced current in iron core.The induced current that produces in the iron core, circulation in perpendicular to the plane of flow direction forms eddy current loss.
Can reduce " eddy current loss " through iron core being processed into sheet.In order to reduce eddy current loss, the iron core of transformer builds up with lamination insulated from each other, makes eddy current in the loop of thin-and-long, through less cross section, to increase the resistance on the eddy current path.If reduce eddy current in theory, lamination thickness is thin more, and the iron core slip of splicing is narrow more, and effect is good more.But lamination is thin more, and its processing cost will be high more.
The utility model content
For this reason, the utility model technical problem to be solved is transformer core of the prior art is improved, and then the transformer core that a kind of processing cost is low and loss is lower is provided.
For solving the problems of the technologies described above; A kind of transformer core of the utility model; Form by the multilayer iron core unit; Said iron core unit comprises stem stem unit and iron yoke unit, and said iron core unit is spliced into " day " shape by two groups of iron yoke unit and three core assembly pole units, and the seam between said iron yoke unit and the said stem stem unit is 45 degree.
Said iron yoke unit is cascaded by a plurality of iron yoke subdivisions; Said stem stem unit is cascaded by a plurality of stem stem subdivisions, and the core column sheet that said iron yoke subdivision is arranged by multi-disc iron yoke sheet ladder in the said stem stem subdivision that forms and be adjacent cooperates the ladder splicing.
Said iron yoke subdivision and said stem stem subdivision are respectively 5 grades of ladders and arrange.
5 grades of ladders in the said iron yoke subdivision in the iron core unit of one deck are arranged as each level to be made up of a slice iron yoke sheet, and the core column sheet of ladder splicing in the said stem stem subdivision that is adjacent also is that each grade is made up of a slice core column sheet; 5 grades of ladders in the said iron yoke subdivision in all the other iron core unit are arranged as each level to be made up of two iron yoke sheets, and the core column sheet of ladder splicing in the said stem stem subdivision that is adjacent also is that each level is made up of two core column sheets.
Said iron yoke sheet and said core column sheet are cold-reduced silicon sheet.
The thickness of every said iron yoke sheet and said core column sheet is 0.23～0.3mm.
The technique scheme of the utility model is compared prior art and is had the following advantages,
(1) in the said transformer core of the utility model; Form by many groups iron core unit; Every group of said iron core unit cascaded by the multilayer lamination, and every lamination is spliced into " day " shape by two iron yoke sheets and three core column sheets, and the seam between said iron yoke sheet and the said core column sheet is 45 degree; Angle through changing seam has changed the magnetic resistance of core column sheet and then has changed the magnetic flux density through every core column sheet, thereby realizes reducing loss on the low basis of processing cost.
(2) in the said transformer core of the utility model, each layer core column sheet of arranging and be adjacent through ladder between the said iron yoke of each layer sheet cooperates the ladder splicing, and structure is compact more, and the volume of transformer is littler.
(3) in the said transformer core of the utility model; Preferred in the middle of 5 grades of ladders in the said iron yoke subdivision in the iron core unit of one deck be arranged as each level and form by a slice iron yoke sheet, and the core column sheet of ladder splicing in the said stem stem subdivision that is adjacent also is that each grade is made up of a slice core column sheet; 5 grades of ladders in the said iron yoke subdivision in all the other iron core unit are arranged as each level to be made up of two iron yoke sheets, and the core column sheet of ladder splicing also is that each level is made up of two core column sheets in the said stem stem subdivision that is adjacent, the production efficiency height.
(4) in the said transformer core of the utility model; Preferred every group of said iron core unit cascaded by 5 layers of lamination, and said lamination is a cold-reduced silicon sheet, and the thickness of every said lamination is 0.23～0.3mm; Promptly can not increase processing cost, can guarantee that again eddy current loss is minimum.
