[embodiment]
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to accompanying drawing 1,2,3,9,11.A kind of three-phase three-column amorphous matter iron core of the utility model, contain noncrystalline outer unshakable in one's determination 1, inner iron core 2, amorphous thin ribbon cuts off and engages mouth 4, resin glue coating 5, end face chevron support iron plate 6, internal layer chevron support iron plate 7, upper clamping piece 11, lower clamping piece 12, hanger 13, insulating material 14, upper side shelves pressure 15 and base 17, described three-phase three-column amorphous matter iron core is by an exterior capacity 1, two inner iron cores 2 constitute, the amorphous thin ribbon of amorphous iron core 3 usefulness extremely thin (about 0.025mm) is here reduced, stack, overlap joint is made, amorphous thin ribbon cuts off joint mouth 4 and engages with overlapping mode, and the cut-out of single-core circulation engages mouth can be provided with a place by the size of core dimensions, two places or more than three places; According to the size of transformer capacity, three-phase three-column amorphous matter iron core can be designed to the single-core layer: two inner iron cores and one are outer unshakable in one's determination, or are made up of two layers unshakable in one's determination or three layer institutes more than the iron core.
Because of amorphous thin ribbon extremely thin, its mechanical strength can't support the weight of itself, also can produce fragment sometimes, so, can coat the filler resin glue of strengthening with glass fiber mesh at end face of iron core, treat that the intensity of the resin glue coating 5 that its sclerosis back forms strengthens intensity (referring to accompanying drawing 4) unshakable in one's determination.
Referring to accompanying drawing 5～9.Expansion along with transformer capacity, iron core also increases thereupon, singly be that resin glue coating 5 is difficult to support its weight, and the characteristic of amorphous iron core is to be subject to external stress influence, the method that the utility model is taked is the weight after bonding support iron plate on the iron core supports unshakable in one's determination the increase.The utility model is made the chevron support iron plate by the shape of three-phase three-column amorphous matter iron core, has: end face surpasses the height of amorphous iron core 3 with chevron support iron plate 6---its chevron pin is longer; Internal layer is with chevron support iron plate 7---its chevron pin is shorter, and is short in the height of amorphous iron core 3; Cutting circular hole 8 is set on support iron plate, and purpose is to strengthen and the bonding contact-making surface of resin glue, makes support iron plate and resin glue adhesively tighter; At end face fixedly round tip 9 (not having on chevron support iron plate 7 at internal layer) of welding is set on chevron support iron plate 6, conveniently passes set bolt 16 and make it to be connected with clamping component; The bottom of support iron plate is bent into the L type bending reinforcement 10 of 90 degree, and protrudes the yoke portion edge of amorphous iron core, can strengthen the enabling capabilities of iron plate by the iron plate bending part when iron core is erect.End face is bonded in the end face of upper strata iron core with chevron support iron plate 6 usefulness resin glues, and internal layer is bonded in the inner face of the iron cores that are made of two or more layers unshakable in one's determination with chevron support iron plate 7 usefulness resin glues.Because of what adopt is the fixing supporting way of side gluing, the suffered stress of amorphous iron core 3 lamination directions is minimized, thereby guarantee optkmal characteristics (iron loss and noise) unshakable in one's determination.
The weight of the visual iron core of the thickness of support iron plate (comprising intensity) designs and mates.
Referring to accompanying drawing 10,11.Single use support iron plate also is not enough to erect relievedly with handling and lifts three-phase three-column amorphous matter iron core, therefore, has also used clamping component when using support iron plate to support amorphous iron core 3 weight.Clamping component of the present utility model comprises upper clamping piece 11, lower clamping piece 12, upper side shelves pressure 15 and set bolt 16; Described upper clamping piece 11, lower clamping piece 12 are the metallic plate of bathtub construction, are provided with hanger 13 at upper clamping piece 11.Clamp with two upper clamping pieces 11 in the upper end unshakable in one's determination that is bonded with support iron plate, be lined with the upper side shelves between two upper clamping pieces 11 and press 15; Clamp with two lower clamping pieces 12 in the lower end unshakable in one's determination that is stained with support iron plate, use set bolt 16 lock rings between two lower clamping pieces 12; Mounting seat 17 on lower clamping piece 12.
The three-phase three-column amorphous matter that assembling is finished is unshakable in one's determination to lift in whole handling, can vertically place (setting).
