Description
Technical field
The present invention relates to a kind of structure of transformer body, relate in particular to the machine body structure of amorphous alloy iron core dry distribution transformer.
Background technology
The iron core of dry-type distribution transformer adopts the folded system of cold-reduced silicon sheet to form basically at present, and the cross section of iron core column is rounded, and this iron core is because the magnetic property of silicon steel sheet own makes that the no-load loss of transformer is bigger.
Therefore existing a kind of amorphous alloy transformer, though obtained application with its good soft magnet performance, less characteristics such as no-load loss, but, because the width kind of amorphous alloy strips is fewer, be difficult to make the cross section of amorphous iron core rounded, therefore the cross section of the iron core column of amorphous alloy iron core dry distribution transformer is rectangular usually, and the cross section of the high and low pressure coil that matches is also rectangular.
Therefore, improve the distribution of high and low pressure coil bight electric field strength, making the machine body structure compactness is one of insider's problem of being devoted to study.
Summary of the invention
The object of the present invention is to provide a kind of machine body structure that can improve the electric-field intensity distribution in high-voltage coil and low-voltage coil bight and make the compacter amorphous alloy iron core dry distribution transformer of machine body structure.
The machine body structure of a kind of amorphous alloy iron core dry distribution transformer provided by the present invention, comprise amorphous alloy iron core, the high and low pressure coil that coaxial laminar is arranged, upper and lower folder and insulation fagging, it is characterized in that: it comprises that also one is arranged on the insulating cylinder between the high and low pressure coil, and between described lower clamping piece and high and low pressure coil lower end and several insulation pressing that between described upper clamping piece and high and low pressure coil upper end, are furnished with respectively; Wherein: described high and low pressure coil is to be seated on the lower clamping piece by these some insulation pressing that are furnished with, and yoke is to be suspended on the high and low pressure coil by these some insulation pressing that are furnished with and described insulation fagging on the described amorphous alloy iron core; Around the insulating cylinder that is provided with between described high-tension coil, low-voltage coil and the high and low pressure coil is respectively with the cuboid of fillet; The machine body structure of described amorphous alloy iron core dry distribution transformer, high-tension coil can be controlled by some insulation pressing to the distance of insulating cylinder to the distance and the low-voltage coil of insulating cylinder.
The machine body structure of above-mentioned amorphous alloy iron core dry distribution transformer is provided with insulation board to amorphous alloy iron core between the other post in the outer end at the side high-tension coil.
The machine body structure of above-mentioned amorphous alloy iron core dry distribution transformer, between lower clamping piece and high and low pressure coil lower end and between described upper clamping piece and high and low pressure coil upper end, the quantity that is respectively the insulation pressing of every phase bolster is eight, each two at its mesohigh and low-pressure side lead-in wire place, about the device body is alternate each two.
Adopt above-mentioned technical solution, the present invention is not only because the iron core that adopts amorphous alloy material to make, no-load loss is had substantial degradation, and make the machine body structure of this dry-type distribution transformer compacter, volume is little, reduction material consumption amount, insulation fagging wherein also plays the effect of supporting amorphous alloy iron core and the effect of reinforced insulation simultaneously, and the present invention has also improved the electric-field intensity distribution in the rectangular high-voltage coil and low-voltage coil bight of cross section.
