Description
Technical field
Field is manufactured the present invention relates to design of transformer, it is more particularly to a kind of to strengthen the amorphous alloy of anti-short circuit capability
Heart distribution transformer winding construction.
Background technology
At present, in terms of Accident of Transformer situation analysis, anti-short circuit capability is not important as power transformer accident enough
Reason.For enhancing amorphous oil-immersed transformer winding anti-short circuit capability, each producer all tries every possible means, and is adopted low voltage layer type coil more
Use foil structure, the axial electromagnetic force very little that axial leakage field is produced.Coil uses side plate, wood block filler and 10mm epoxies on radial
Glass-cloth board is in coil both sides stretching and control coil axial compression technique, and the guarantee wire during coiling
Tensile force.But due to the influence of technological level and production equipment etc., tend not to control well.Particularly in short circuit, spoke
Coil diameter is set to become big to electromagnetic force.When act on the tension on wire it is excessive when the radial short axle side of winding can produce forever
Deformation (interior loop is recessed inward, and exterior loop is swollen outward) long, and due to the radial short axle line part of pre-structure on the outside of A, C phase coils
Divide and do not support well, cause winding deformation, this deformation generally causes turn-to-turn short circuit with wire insulation breakage.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of amorphous alloy core distribution change for strengthening anti-short circuit capability
Depressor winding construction.
The technical solution adopted for the present invention to solve the technical problems is：It is a kind of to strengthen the amorphous alloy of anti-short circuit capability
Heart distribution transformer winding construction, it includes the coil that three-phase is unshakable in one's determination and is wrapped in iron core；Three-phase upside unshakable in one's determination is set
Upper clamping piece is equipped with, downside is provided with lower clamping piece, and the left and right sides is each provided with side plate；The side plate passes through with upper clamping piece and lower clamping piece
Bolt is fixed；Reinforcing plate is further fixed on the inside of the side plate；The reinforcing plate is pressed on coil；The reinforcing plate and coil
Gap be provided with cardboard.
The reinforcing plate is a few font bent plates；The crowning of a few font bent plates is pressed on coil, and several fonts are curved
Two pawl ends of plate are bolted on side plate；Reinforcement is provided with the pawl end of several fonts of reinforcing plate.
Beneficial effects of the present invention：The present invention a kind of enhancing anti-short circuit capability Amorphous Alloy Distribution Transformer around
Group structure, installs reinforcing plate mounting means additional, it is ensured that coil is in short circuit, and amorphous coil is radial using on the outside of A, C phase coils
Short-axis direction straight line portion reaches the spacing of reinforcing plate, radial electromagnetic force by the fixation of side plate by good contact area
Make exterior loop there is no space swollen outward during effect, reach the purpose of protective winding deformation.
