Description

The amorphous alloy transformer winding construction that anti-short circuit capability is high

Technical field

This utility model relates to transformer technology field, is specifically related to the amorphous alloy transformer that a kind of anti-short circuit capability is high Winding construction.

Background technology

In recent years, the Accident of Transformer situation analysis announced in recent years from State Grid Corporation of China, anti-short circuit capability is the most Become the major reason of amorphous alloy transformer accident.Amorphous alloy transformer winding is rectangular configuration, and suffered electric power is remote not As common transformer circle winding is uniform, when bearing sudden short circuit electric power, it is easier to deformation.Amorphous alloy transformer body is adopted Using axial load-carrying members, rectangle winding is compressed by folder from top to bottom and pressing plate, low voltage layer type coil many employings foil structure, axially The axial electromagnetic force that leakage field produces is the least.In rectangle winding, electric current is producing stray field about, be divided into axial component and width to Component, axial leakage field produces diametral force with the Interaction Law of Electric Current in rectangle winding, along rectangle winding width radially to power, makes Interior winding is stressed, and outer winding tension power effect (interior loop is the most recessed, and exterior loop is the most swollen), to burn because of sudden short circuit The radial deformation that amorphous alloy transformer disassembles middle discovery long axis direction is the most serious.And long axis direction between low-voltage coil and iron core Not having good inner support, inside contract, to bear, the winding deformation that power causes when short circuit, these deformation are generally with main minor insulation Structural damage, time serious, even wire is pulled off.

Utility model content

For solving above-mentioned technical problem, the purpose of this utility model is the non-crystaline amorphous metal providing a kind of anti-short circuit capability high Transformer winding structure, can improve support strength when winding conducting wire is deformed inward.

For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions: one Plant the amorphous alloy transformer winding construction that anti-short circuit capability is high, including eight iron cores and three coil windings, these eight iron cores In, four iron cores are disposed side by side on the top unshakable in one's determination that other four is arranged side by side, and form four unshakable in one's determination group arranged from left to right Structure, each group unshakable in one's determination comprises two iron cores set up and down, is positioned at four iron cores on upper strata and is positioned at the four of lower floor It is provided with between individual iron core between epoxy resin bonded fiber, and each two iron core adjacent in left and right and is provided with cardboard, arrange from left to right Four unshakable in one's determination group in, adjacent unshakable in one's determination group of each two is respectively equipped with an epoxy cylinder, rotating around being provided with on each epoxy cylinder Coil windings.

Further, the thickness of described epoxy resin bonded fiber is 6~10mm.

The beneficial effects of the utility model are: this utility model four iron cores on upper strata and four ferrum being positioned at lower floor Being provided with epoxy resin bonded fiber between the heart, iron core is provided with epoxy cylinder, and coil windings is wound on epoxy cylinder, so that low-voltage line Between circle and iron core, long axis direction defines good inner support, improves support strength when winding conducting wire is deformed inward, Can bear and inside contract the winding deformation that power causes when short circuit.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation removing part iron core of the present utility model.

Detailed description of the invention

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 protection domain of the present utility model is made apparent clearly Define.

As depicted in figs. 1 and 2, the amorphous alloy transformer winding construction that a kind of anti-short circuit capability is high, including eight iron cores 1 With three coil windings 2, in these eight iron cores 1, four iron cores 1 are disposed side by side on the top of the iron core 2 that other four is arranged side by side, Form the structure of four arranged from left to right group unshakable in one's determination, each group unshakable in one's determination comprises two set up and down unshakable in one's determination 1, is positioned at Four iron cores on upper strata and be provided with epoxy resin bonded fiber 3, and each two adjacent in left and right between four iron cores of lower floor It is provided with cardboard 5 between unshakable in one's determination 1, in unshakable in one's determination group of four arranged from left to right, adjacent unshakable in one's determination group of each two is respectively equipped with one Individual epoxy cylinder 4, rotating around being provided with coil windings 2 on each epoxy cylinder 4.

Furtherly, the thickness of described epoxy resin bonded fiber 3 is 6~10mm.The thickness of epoxy resin bonded fiber 3 is according to capacity Change and change.Such as, thickness be the epoxy resin bonded fiber of 8mm be applicable to transformator that capacity is 200kVA~400kVA around Group structure.

This utility model at four iron cores on upper strata and is provided with epoxy resin bonded fiber 3 between four iron cores of lower floor, Iron core is provided with epoxy cylinder 4, and coil windings 2 is wound on epoxy cylinder 4, so that long axis direction shape between low-voltage coil and iron core Having become good inner support, anti-short circuit capability is strong, improves support strength when winding conducting wire is deformed inward, can bear The winding deformation that power causes is inside contracted when short circuit.

The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every Utilize equivalent structure or equivalence flow process conversion that this utility model description and accompanying drawing content made, or be directly or indirectly used in Other relevant technical fields, are the most in like manner included in scope of patent protection of the present utility model.
