Abstract
The utility model discloses an insulating dry -type transformer of pure epoxy, the linear motor mover comprises an iron core, high -low pressure combination formula coil, steel sheet bend folder and upper portion copper bar, high -low pressure combination formula coil is formed with epoxy integral cast around the back by high -pressure coil and low voltage coil cover, each steel sheet is bent the bottom surface of folder and is fixed mutually with iron core the left side post and iron core the right post respectively, each looks high -low pressure combination formula coil is fixed mutually through the alternate connecting pipe that is located its front side, the upper portion copper bar is fixed on the bend upper portion of folder of the steel sheet that lies in the iron core rear side through the insulator, the lower extreme at the upper portion copper bar is fixed to the lead -out wire of high -low pressure combination formula coil. The utility model provides the high anti short circuit ability and the operational reliability of transformer has the excellent features of resistant high wet, resistant dust, salt spray resistance.
Description
Technical field
The utility model relates to a kind of dry-type transformer.
Background technology
Epoxy resin-insulated dry type transformer can improve insulation characterisitic, the impact resistance of transformer, reduce partial discharge quantity, extend the service life of transformer, the environment such as transformer when operation air humidity, dust, salt fog have dropped to minimum on the impact of transformer, improve the operational reliability of transformer, there is very high competitiveness in future market.
Summary of the invention
The purpose of this utility model has just been to provide a kind of pure epoxy resin insulating dry type transformer that improves the insulation characterisitic of transformer, resistance to high humidity, salt spray resistance, resistance to dust, and for achieving the above object, its technical scheme of taking is:
Comprise iron core, high-low pressure combined-type coil, steel plate bending folder and top copper bar, high-low pressure combined-type coil is poured into a mould and is formed with epoxy resin integral around rear by high-tension coil and low-voltage line snare, between the internal layer of high-low pressure combined-type coil and skin, be provided with solvent-free grid cloth, iron core sleeve is in high-low pressure combined-type coil, before and after iron core top, the left end of side is fixed with respectively iron core left side post, before and after iron core top, the right-hand member of side is fixed with respectively iron core the right post, steel plate bending folder is two, they are horizontally set at respectively the both sides, front and back above iron core, the bottom surface of each steel plate bending folder fixes with iron core left side post and iron core the right post respectively, each phase high-low pressure combined-type coil fixes by the alternate tube connector that is positioned at its front side, top copper bar is fixed on the top of the steel plate bending folder that is positioned at iron core rear side by insulator, the lead-out wire of high-low pressure combined-type coil is fixed on the lower end of top copper bar.
The utility model has been broken conventional transformer high and low pressure coil and has been separated, utilized air-insulated mentality of designing, adopted high and low pressure coil cover around structure, high-low pressure conductor is all sealed in epoxy resin, has the good characteristic of resistance to high humidity, resistance to dust, salt spray resistance. By steel plate bending folder, iron core left and right side column is clamped, by the tension of top copper bar, between three-phase coil, add alternate tube connector, make transformer form a firmly entirety. Not only improved the efficiency of production and processing, and high-tension coil, low-voltage line snare be around integrated poured, space reduces, and axially short-circuit electromotive force reduces, the stability while having improved operation.
