Abstract
The utility model discloses an amorphous distribution transformer's structure unshakable in one's determination, including unshakable in one's determination and insulating backplate, this iron core has two stem portions, upper yoke portion and indisputable yoke portion down, and respectively around being equipped with the coil winding, lower indisputable yoke portion unshakable in one's determination be the overlap joint structure in two stem portions unshakable in one's determination, two core -covering part of insulating backplate, and two core -covering part of insulating backplate pass through the silica gel cladding and in the lower indisputable yoke portion of iron core, are equipped with U -shaped silicon steel sheet skeleton in the iron core, and this U -shaped silicon steel sheet skeleton is detained and is established on the coil winding, separates the terminal surface and the iron core of coil winding. The utility model provides a whole indisputable yoke portion is down sealed to insulating backplate, and tighter reality, can avoid the amorphous piece to spill over. In addition, when transformer operation or transportation oscillation generation, effort that U -shaped silicon steel sheet skeleton can the buffer coil winding produces the iron core reduces vibration unshakable in one's determination to the production of the piece that the suppression caused because of iron core vibration.
Description
Technical field
This utility model is related to transformer technology field, particularly to a kind of core construction of amorphous distribution transformer.
Background technology
Amorphous alloy distribution transformer is described as the power transformer product of 21st century energy-conservation, but because of its band material unshakable in one's determination
The particularity of matter itself, the fragment producing in manufacture process easily remains in oil, and the safe operation to transformator causes a hidden trouble.
In addition, transformator is in transport or operation, vibration can be produced, iron core be impacted so that iron coring vibration, be more also easy to produce broken
Piece.In prior art, strong to the processing method controllability of fragment it is impossible to ensure the quality of product.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of knot unshakable in one's determination of amorphous distribution transformer
Structure, not only can reduce producing it is also possible to the fragment preventing overflows of fragment.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, this utility model is achieved through the following technical solutions: one
Plant the core construction of amorphous distribution transformer, including unshakable in one's determination and insulation protective board, this iron core has two stem portions, upper yoke portion
With lower yoke portion, two stem portions unshakable in one's determination are arranged with coil windings respectively, lower yoke portion unshakable in one's determination is bridging arrangement, institute
State two covering portion of insulation protective board, two covering portion of described insulation protective board pass through gel coated in described lower yoke portion unshakable in one's determination
On, iron core in be provided with u shape stalloy skeleton, this u shape stalloy skeleton be located in coil windings, by the end face of coil windings with
Iron core separates.
Further, this u shape stalloy skeleton is arranged at the downside of coil windings.
Further, it is provided with dividing plate between two coil windings.
The beneficial effects of the utility model are: be stained with absolutely by silica gel in lower yoke portion unshakable in one's determination of the present utility model
Edge backplate, insulation protective board is by whole lower yoke portion encapsulating unshakable in one's determination, and relatively tight consolidation, and amorphous fragment can be avoided to overflow.
In addition, being provided with u shape stalloy skeleton in iron core, when transformer station high-voltage side bus or transport produce vibration, u shape stalloy skeleton can delay
Rush coil windings to the active force producing unshakable in one's determination, reduce iron coring vibration, thus suppression is because of the product of the fragment caused by iron coring vibration
Raw.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the expanded view of the insulation protective board in this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model
Define.
As depicted in figs. 1 and 2, a kind of core construction of amorphous distribution transformer, including unshakable in one's determination 1 and insulation protective board 2, this ferrum
The heart 1 has two stem portions 11, upper yoke portion 12 and lower yoke portion 13, and unshakable in one's determination 1 two stem portions 11 are arranged with line respectively
Circle winding 3, unshakable in one's determination 1 lower yoke portion 13 is openable bridging arrangement, and insulation protective board 2 has two symmetrical with respect to middle part
Individual covering portion 21, the middle part of insulation protective board 2 has two openings 22 being located between two covering portion, two of insulation protective board 2
Covering portion 21 passes through gel coated in described unshakable in one's determination 1 lower yoke portion 13, is provided with u shape stalloy skeleton 4, this u shape in unshakable in one's determination 1
Stalloy skeleton 4 be located in coil windings 3, and the end face of coil windings 3 is separated with unshakable in one's determination 1.
Furtherly, this u shape stalloy skeleton 4 is arranged at the downside of coil windings 3.
Furtherly, it is provided with dividing plate 5 between two coil windings 3.
During work, by insulation protective board 2 according to lower yoke shape shear forming, the insulation protective board after shearing has two openings
With two covering portion.When device body assembles, u shape stalloy skeleton 4 is buckled in coil windings 3, and insulation protective board 2 is positioned over coil
At the lower surface of winding 3, the unshakable in one's determination 1 lower yoke portion 13 overlapping is opened, unshakable in one's determination 1 is pushed in coil windings 3, makes
Two stem portions 11 obtaining unshakable in one's determination 1 penetrate in corresponding coil windings 3 and the opening 22 of insulation protective board 2, then beating iron core 1
Lower yoke portion 13 overlap joint opened merges.Silica gel is scribbled on lower yoke portion 13, after the completion of lower yoke portion 13 overlap joint merges, by insulation shield
Two covering portion 21 of plate 2 bend 90 degree, thus whole insulation protective board 2 passes through gel coated in lower yoke portion 13 unshakable in one's determination.
Whole lower yoke portion 13 unshakable in one's determination is encapsulated by insulation protective board 2, and relatively tight consolidation, can avoid the amorphous producing
Fragment overflows.In addition, being provided with u shape stalloy skeleton 4 in iron core, u shape stalloy skeleton 4 by the end face of coil windings 3 with unshakable in one's determination
End face separate, transformer station high-voltage side bus or transport produce vibration when, u shape stalloy skeleton 4 can be with buffer coil winding 3 to whole
The active force producing unshakable in one's determination, reduces iron coring vibration, thus suppression is because of the generation of the fragment caused by iron coring vibration.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in
Other related technical fields, are all included in the same manner in scope of patent protection of the present utility model.
