Abstract
The utility model discloses a kind of device for improving dry-type transformer phase insulation level, including：First folder and the second folder, fixed bit on three coils is provided with first folder, fixed bit under three coils is provided with second folder, it is corresponding between fixed bit and fixed bit under three coils on three coils to be provided with three coils, insulation board is provided between the adjacent coil, the insulation board is fixedly connected with first folder and second folder respectively by support member.The structure not only can greatly improve the dielectric level between three-phase coil, improve the reliability of transformer station high-voltage side bus in the case of constant by setting support member and insulation board between adjacent windings in dry-type transformer three-phase coil；And while the dielectric level between ensureing dry-type transformer three-phase coil, the insulation distance between three-phase coil can be suitably reduced, reduces the dosage of silicon steel sheet, reduces the volume of transformer.
Description
Technical field
Dry-Transformer Technology field is the utility model is related to, especially, it is alternate absolutely to be related to a kind of raising dry-type transformer
The horizontal device of edge.
Background technology
Common dry-type transformer is to ensure the dielectric level between three-phase coil at present, generally use increase three-phase coil it
Between the mode of insulation distance realize, so not only add the volume of transformer, while the main material of transformer can be increased
Expect the dosage of silicon steel sheet, cause the increase of transformer holistic cost.
Utility model content
The utility model purpose is to provide a kind of device for improving dry-type transformer phase insulation level, existing to solve
Common dry-type transformer ensures dielectric level between three-phase coil by the insulation distance between increasing three-phase coil in technology
Technical problem.
To achieve the above object, the utility model provides a kind of device for improving dry-type transformer phase insulation level, bag
Include：First folder and the second folder, fixed bit on three coils is provided with first folder, is set on second folder
There is a fixed bit under three coils, setting corresponding between fixed bit and fixed bit under three coils on three coils
There are three coils, insulation board is provided between the adjacent coil, the insulation board is pressed from both sides with described first respectively by support member
Part is fixedly connected with second folder.
Further, the insulation board is at least provided with two pieces.
Further, the support member is at least provided with four.
Further, the support member is screwed and is connected with first folder and second folder respectively.
The utility model has the advantages that：A kind of raising dry-type transformer phase insulation of the present utility model is horizontal
Device, the structure by setting support member and insulation board between adjacent windings, not only dry-type transformer three-phase coil away from
In the case of constant, the dielectric level between three-phase coil can be greatly improved, improves the reliability of transformer station high-voltage side bus；And
While ensureing the dielectric level between dry-type transformer three-phase coil, the insulation distance between three-phase coil can be suitably reduced, is subtracted
The dosage of few silicon steel sheet, reduce the volume of transformer.
Brief description of the drawings
Below with reference to figure, the utility model is described in further detail.Form the accompanying drawing of the part of the application
Further understood for providing to of the present utility model, schematic description and description of the present utility model is used to explain this reality

Product.
Preferably, the insulation board 6 improves the dielectric level between three-phase coil at least provided with two pieces.
Preferably, the support member 7 is at least provided with four so that insulation board 6 respectively with the first folder and the second folder phase
It is fixed.
Preferably, the support member 7 is screwed and is connected with first folder 1 and second folder 2 respectively,
Screw connection ease of assembly and dismounting.
As can be seen from the above description, the utility model the above embodiments realize following technique effect：The knot
Structure between adjacent windings 5 by setting support member 7 and insulation board 6, not only in dry-type transformer three-phase coil apart from constant
In the case of, the dielectric level between three-phase coil can be greatly improved, improves the reliability of transformer station high-voltage side bus；And ensureing dry type
While dielectric level between Three-Phase Transformer coil, the insulation distance between three-phase coil can be suitably reduced, reduces silicon steel sheet
Dosage, reduce the volume of transformer.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model；For this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
