Abstract
The utility model discloses an amorphous alloy iron core with thin epoxy coatings, the thin epoxy coatings are coated on two sides in addition to lap joint regions, and the thickness of each epoxy coating is 0.3mm-0.8mm. The thickness of each epoxy coating is 0.4mm. The thin epoxy layers of 0.3mm-0.8mm are coated on the surfaces on two sides of the amorphous alloy iron core, thereby being capable of significantly reducing the stress generated by epoxy curing, further reducing the no-load loss and the no-load current and improving the electrical performance of the amorphous iron core; simultaneously, the thickness of the coatings becomes thinner, the epoxy curing time is shortened, and the production efficiency of the amorphous iron core is improved; and furthermore, as the overall size of the iron core is reduced, the outline dimension of a transformer is correspondingly reduced, and the manufacturing cost of the transfer is further reduced.
Description
Technical field
The utility model belongs to field transformer, particularly a kind of thin epoxy coating amorphous alloy iron core.
Background technology
Non-crystaline amorphous metal is the new material that utilizes flash set technology to make, has excellent soft magnet performance, be silicon steel sheet, permalloy and ferritic regeneration product, be used for distribution transformer as transformer magnetic conduction magnetic circuit more, it is compared with silicon steel and more helps being magnetized and degaussing, thereby has good excitation property and iron loss characteristic, when being used to process transformer core, because its magnetization is quite easy, can reduce the no-load loss of transformer significantly.
Because the hardness height of amorphous alloy material, thin thickness, and after heat treatment amorphous sheet becomes fragile, so no matter be to produce assembling, still in the use of amorphous transformer, all can inevitably produce some fragments, if do not controlled, then when transformer moved, the amorphous fragment that circulates with the transformer insulating radiation just might cause problems such as short circuit and burn out transformer.The existence of obvious inner amorphous fragment all has bigger influence to the performance and the reliability of amorphous transformer itself.
For the shape of fixing amorphous alloy iron core and prevent that the amorphous fragment from falling into transformer coil and causing short trouble, amorphous transformer core is general all at the thick epoxy resin of coating on both sides 2mm at present.But because epoxy coating thickness is bigger, when curable epoxide, be easy to generate stress, and amorphous iron core counter stress is very responsive, causes the no-load loss of amorphous iron core and no-load current bigger, influences transformer performance; Thicker epoxy coating has increased curing time simultaneously, causes production efficiency low, and delivery cycle is long; Moreover the epoxy coating that 2mm is thick strengthens core dimensions, and device body, the fuel tank profile of transformer all increase, and corresponding transformer cost is higher.
The utility model content
The purpose of this utility model is to provide a kind of thin epoxy coating amorphous alloy iron core, to solve when the curable epoxide the excessive technical problem such as amorphous iron core electrical property reduction that causes of stress.
For solving above technical problem, the technical scheme that the utility model provides is as follows:
A kind of thin epoxy coating amorphous alloy iron core, the overseas one deck epoxy coating that is coated with of overlap is removed in its both sides, it is characterized by, and the thickness of described epoxy coating is less than 1mm.
Further be characterized as, described epoxy coating thickness is 0.3mm-0.8mm.
Further be characterized as, described epoxy coating thickness is 0.4mm.
Advantage of the present utility model is:
The amorphous alloy iron core both side surface is applied the thin epoxy of one deck less than 1mm, can significantly reduce the stress of amorphous iron core, thereby reduce no-load loss and no-load current, improve the electrical property of amorphous iron core; Coating layer thickness attenuation simultaneously, the curable epoxide time shortens, and has improved the production efficiency of amorphous iron core; Moreover, because the iron core overall dimensions reduces, dwindled the overall dimension of transformer accordingly, can further reduce the manufacturing cost of transformer.
Description of drawings
Fig. 1 is the amorphous alloy iron core front view of the utility model one execution mode.
Fig. 2 is the end view of Fig. 1.
Embodiment
Below by specific instantiation and accompanying drawings execution mode of the present utility model, those skilled in the art can understand other advantage of the present invention and effect easily by the content that this specification disclosed.The utility model also can be implemented or be used by other different instantiation, and the every details in this specification also can be based on different viewpoints and application, carries out various modifications and change under the spirit of the present utility model not deviating from.
As depicted in figs. 1 and 2, thin epoxy coating amorphous alloy iron core of the present utility model is provided with one deck epoxy coating 2 on the surface that amorphous alloy iron core 1 needs to apply epoxy coating, generally be to apply epoxy coating at the U on ring transformer cores top type zone (seeing that A-A is with the upper part among Fig. 1), epoxy coating thickness is less than 1mm.
Realize that method of the present utility model is, remove the dust and the chip on amorphous alloy iron core 1 surface with brush; On amorphous alloy iron core 1, A-A along the line sticks a shielding tape in following place, prevents that epoxy resin from exosmosing; With hairbrush epoxy resin evenly is coated in the amorphous alloy iron core 1 iron core surface more than the A-A along the line, coating layer thickness is 0.3mm-0.8mm, and preferred coating layer thickness is 0.4mm; Amorphous iron core is put into the baking oven baking, and baking temperature is 100-150 ℃, and stoving time is 10-50min; After treating that epoxy coating solidifies, iron core is stood up to apply second, repeat above-mentioned steps.Certainly the performance for the epoxy coating that can make 0.3mm-0.8mm reaches instructions for use, change the allotment index of epoxy resin, guarantees that the performance of each side is issued to the performance of the epoxy coating of existing 2mm thickness in the situation of low thickness.
Carry out epoxy coated in this way, can make coating layer thickness be reduced to not enough 1mm by original 2mm, the suffered stress of amorphous iron core diminishes, and simultaneously, the coating attenuation both can make coating even, solidifies easily again, has shortened 60% curing time; The whole height of iron core reduces 2-3mm, thereby can reduce the size of transformer, has reduced the transformer manufacturing cost.
The foregoing description is illustrative principle of the present utility model and effect thereof only, but not is used to limit the utility model.Any those skilled in the art all can be under spirit of the present utility model and category, and the foregoing description is modified and changed.Therefore, rights protection scope of the present utility model should be listed as claims.
