Abstract
This invention discloses a compound iron-core element and its manufacturing method, in which, the core is made up of an iron base nm crystal alloy core and amorphous alloy core or silicon-steel plate core in the mode of coaxial lamination or concentric circle cover, the iron base nm crystal alloy core and the amorphous alloy core are formed by rolling the strips of the alloys to be heat-processed and combined.
Description
Technical field the present invention relates to a kind of element that is used for perceptual device, relates in particular to a kind of combined iron-core element and manufacture method thereof that is specially adapted to measuring current transformer.
Prior art is used for the precision current instrument transformer of measuring circuit, uses sloping film alloy and cobalt base amorphous alloy iron core usually, and the shortcoming of using this material is the manufacturing cost height, and uses silicon sheet core to make, and then the mutual inductor measuring accuracy of measurement of Zhi Zuoing is low.
Summary of the invention the objective of the invention is the problem at above-mentioned prior art existence, provides a kind of with low cost, simple in structure, has the high combined iron-core element of quality of excellent magnetic energy.
Technical scheme of the present invention comprises two iron-core workpieces of forming of iron core independently each other, it is characterized in that described iron-core workpiece be two independent each other, the iron core of unlike material constitutes with different combining forms each other.
Described two each other independently iron core be respectively iron-base nanometer crystal alloy iron core and amorphous alloy iron core or iron-base nanometer crystal alloy iron core and silicon sheet core, described combining form is mutually stacked or mutual ring sets of two separate iron cores.
Described iron-core workpiece is perhaps constituted by the with one heart mutual ring set of its height two iron cores identical with shape by mutual stacked the constituting of its inside and outside footpath two iron core coaxial lines identical with shape.
Described amorphous alloy iron core and iron-base nanometer crystal alloy iron core are reeled by non-crystalline thin-band and nano-crystalline thin band respectively and are made annular, and described silicon sheet core is reeled by silicon steel sheet or the folded annular that is made for
Described iron-core workpiece is provided with sheath, and described sheath is formed by being ring-like body and ring-like upper shield, and the inwall suitable for reading of described body is provided with a groove along perisporium, and the outward flange of described upper shield is curved.
Between the top of iron-core workpiece and bottom and sheath, be provided with foam-rubber cushion or scribble electronics silica gel; Described sheath is close to sponge, iron-core workpiece.
This method comprises: the iron core that non-crystaline amorphous metal and iron-base nanometer crystal alloy strip is rolled into required form respectively; Or it is silicon steel sheet is folded or roll into the iron core of required form.By the required technological parameter requirement of product above-mentioned made amorphous alloy iron core and iron-base nanometer crystal alloy iron core are heat-treated respectively.With above-mentioned after heat treatment the iron-base nanometer crystal alloy iron core and amorphous alloy iron core or silicon sheet core mutually stacked or mutual ring set be combined into iron-core workpiece, with the sheath of packing into of the iron core after the combination, closely cooperate between sheath and iron-core workpiece and two iron cores.
The present invention utilizes the iron core magnetic property of two kinds of unlike materials to be combined into iron-core workpiece, form a kind of special magnetic signature, with this perceptual device of making, especially for the current measurement instrument transformer, not only has excellent electromagnetic performance, and, replace expensive cobalt-based and sloping film alloy material with cheap material, reduce cost, replace the part silicon steel sheet with iron-base nanometer crystal alloy, improve the class of cost performance of product and iron core product, improve accuracy of detection, reduce leakage current loss.
Description of drawings Fig. 1 is the structural representation of an embodiment of the present invention.Fig. 2 is the mansion view of Fig. 1.Fig. 3 is the structural representation of another embodiment of the present invention.Fig. 4 is that Fig. 3 A-A is to cutaway view.
Embodiment as shown in Figure 1, the mutual formation assembling iron core body stacked together of annular amorphous alloy iron core that interior external diameter is identical with shape and iron-base nanometer crystal alloy iron core 2 coaxial lines, and place in its cavity shape sheath identical with described iron-core workpiece profile, that form by body 3 and upper shield 4.The body 3 inboard perisporiums suitable for reading of described sheath are provided with a groove 8, the outward flange shape of upper shield 4 and the groove 8 of body 3 match, and upper shield 4 embeds in the groove 8 of body 3, makes the sheath compactness, be convenient to cooperatively interacting of coiling and iron-core workpiece, sheath is close to iron-core workpiece and two iron cores is combined closely; Surface in the upper and lower part of iron-core workpiece scribbles one deck electronics silica gel 5 respectively.
In another embodiment as shown in Figure 2, the thickness of shape, ring body constitutes iron-core workpiece with highly identical silicon sheet core 7 and iron-base nanometer crystal alloy iron core 2 ' mutually concentric ring set, and place in the sheath of forming by body 3 ' and upper shield 4 ', between the upper and lower part of iron-core workpiece and sheath, respectively be provided with a foam-rubber cushion 6.
