Description
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

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
