Description
Technical field
The utility model belongs to field transformer, particularly a kind of amorphous alloy iron core of mixed coating end face.
Background technology
Non-crystaline amorphous metal is the new material utilizing flash set technology to manufacture, there is excellent soft magnet performance, be used for as transformer magnetic conduction magnetic circuit in distribution transformer at present, it is compared with silicon steel and is more conducive to being magnetized and degaussing, thus has good excitation property and iron loss characteristic.Amorphous alloy transformer compares no-load loss decline about 80% with existing S9 serial transformer, no-load current declines about 50%, and energy-saving effect is remarkable.
Because the hardness of amorphous alloy material is high, thickness is thin, and after heat treatment amorphous sheet becomes fragile, so no matter be in production assembling, or in the use procedure of amorphous transformer, all can inevitably produce some fragments, if do not controlled, then when transformer runs, the amorphous fragment circulated with transformer insulating radiation just likely causes the problems such as short circuit and burns out transformer.The existence of obvious inner amorphous fragment, has larger impact to the performance of amorphous transformer itself and reliability.
In order to fixing amorphous alloy iron core shape and prevent from amorphous fragment from falling into transformer coil causing short trouble, current amorphous transformer core, generally all apply at both sides end face the soft glue that a layer thickness is about 1mm.But because soft glue adhesion strength is weak, after iron core forming form removal, between amorphous sheet, easily cause cracking; Simultaneously in transportation, core window is easily made to be out of shape; When transformer body assembles, because iron core is softer, make assembly manipulation comparatively difficult, and after iron core overlapping part opens, iron core stem stem have the risk of cracking.
Therefore, amorphous alloy iron core end coating structure should adopt certain measure, to solve existing amorphous alloy iron core Problems existing.
Utility model content
The purpose of this utility model is the amorphous alloy iron core providing a kind of Novel end face coating structure, to solve the technical problems such as the soft function of glue coating of existing amorphous iron core is easy to crack.
For solving above technical problem, the technical scheme that the utility model provides is as follows:
A kind of amorphous alloy iron core of Novel end face structure, comprise the overlapping regions and U-shaped region that are made up of amorphous alloy iron core, the common looping transformer core of described overlapping regions and U-shaped region, the amorphous alloy iron core of described Novel end face structure also comprises thin epoxy resin layer and soft glue water layer, described soft glue water layer is coated on the U-shaped sweep in U-shaped region, and described thin epoxy resin layer is coated between soft glue water layer and overlapping regions.
As further improvement of the utility model, the thickness of described thin epoxy resin layer is less than 1mm.
As further improvement of the utility model, the thickness of described soft glue water layer is less than 1mm.
As further improvement of the utility model, very close to each other between described thin epoxy resin layer and soft glue water layer, thin epoxy resin layer and soft glue water layer compact siro spinning technology form one deck adhesive layer.
The beneficial effects of the utility model are as follows:
The new structure adhesive coating that the utility model is less than 1mm by applying one deck to amorphous alloy iron core both sides end face, the adhesion strength between amorphous sheet can be strengthened, prevent the cracking after form removal, can ensure that iron core is indeformable in transportation simultaneously, keep good rectangular window, thus be conducive to the stable of properties of product, because iron core performance easily declines after iron core stress deformation.Coating thin epoxy resin simultaneously near iron core overlapping regions ensure that the convenience that device body assembles, and avoids stem stem to ftracture, and improves device body efficiency of assembling.
