Abstract
The invention relates to a lung-shaped shield stacking technology for a transformer, and belongs to the technical field of transformers. The technical scheme is that the shield structure at the end part of the high-capacity transformer body is lung-shaped, namely, silicon steel plates are inserted into an insulating body support plate and an insulating press plate; a lung-shaped inner cavity is formed through processing, the silicon steel plates are stacked one by one in the insulating part, and the silicon steel plates with different lengths are utilized to form the outline and round corners of the lung shape and fill the whole inner cavity of the insulating part. The lung-shaped shield stacking technology for the transformer has the advantages that, the lung-shaped shielding silicon steel plate adopted by the end part of the transformer body are arranged in the insulating press plate and the support plate, so that the leakage flux problem of the end part of the coil is effectively solved, the whole shielding structure of the transformer is simplified, and the shielding effect is improved.

Background technology
The effect of transformer magnetic screen is the normal work avoided the outside Radiative EMI of the coil windings of transformer, magnetic core (iron core) and affect periphery electronic circuit.Background technology Problems existing is: transformer body end adopts magnetic screen technique unreasonable, and easy generating coil brow leakage leads to, and the shielding construction of transformer whole is complicated, and shield effectiveness is undesirable.
Summary of the invention
The object of the invention is to provide a kind of transformer lobe of the lung shielding stacking technique, transformer body end adopts lobe of the lung shape shielding silicon steel sheet to be arranged in insulating press boards and supporting plate, effective solution end winding leakage flux, simplify the shielding construction of transformer whole, shield effectiveness is better, solves the problems referred to above that background technology exists.
Technical scheme of the present invention is:
A kind of transformer lobe of the lung shielding stacking technique, carries out stack from insulating part inside, comprises following steps:
1) insulating part is fixed on closed assembly platform, and by metal baffle by the block of insulating part open at one end, makes insulating part inner chamber form closing structure;
2) during stack, silicon steel sheet is stack from non-central side direction central side, makes silicon steel sheet two ends and insulating part form self-locking structure; Locate with one end that the straightway of insulating part inner chamber and metal baffle end are silicon steel sheet, the silicon steel sheet other end forms lobe of the lung shape by silicon steel sheet length difference;
3) insulating part of stack limit in limit bottom silicon steel sheet brushes resin, according to insulating part cavity shape, use the silicon steel sheet of different length to form profile and the fillet of lobe of the lung shape, fill full whole insulating part inner chamber;
4) after stack completes, by semi-conductive tape electric iron, press on silicon steel sheet surface, and make bulk silicon steel disc bonding by ground strip;
5) silicon steel sheet surface brush is resinized, and makes resin infiltrate between silicon steel blade, and silicon steel sheet is firmly bonding;
6) with insulating part cover closure insulating part inner chamber, with screw rod riveted joint, form lobe of the lung shielding, the lobe of the lung is shielded in switching process, shielding silicon steel sheet can not depart from from insulating part.
Described insulating part is transformer body insulating supporting plate and insulating press boards.
Good effect of the present invention: high-power transformer device body end profile shielding structure adopts the shielding of lobe of the lung shape, namely embeds silicon steel sheet at device body insulating support plate and insulating press boards inside; Be processed into lobe of the lung shape inner chamber, silicon steel sheet is piecemeal in insulating part carries out stack, uses the silicon steel sheet of different length to form profile and the fillet of lobe of the lung shape, fills full whole insulating part inner chamber.Transformer body end adopts lobe of the lung shape shielding silicon steel sheet to be arranged in insulating press boards and supporting plate, and effectively solve end winding leakage flux, simplify the shielding construction of transformer whole, shield effectiveness is better.
