Description
Technical field
The present invention relates to a kind of transformator lobe of the lung shields stacking technique, belong to transformer technology field.
Background technology
The effect of transformator magnetic shield be avoid the coil windings of transformator, magnetic core (iron core) outwards Radiative EMI and
Affect the normal work of periphery electronic circuit.Background technology exist problem be：Transformer body end adopts magnetic shield technique
It is unreasonable, end turn leakage magnetic flux is easily produced, the overall shielding construction of transformator is complicated, and shield effectiveness is undesirable.
The content of the invention
It is an object of the present invention to provide a kind of transformator lobe of the lung shields stacking technique, transformer body end adopts lobe of the lung shape screen
Cover stalloy to be arranged in insulating press boards and supporting plate, effectively solving end turn leakage magnetic flux, simplify the overall shielding knot of transformator
Structure, shield effectiveness more preferably, solve the problems referred to above that background technology is present.
The technical scheme is that：
A kind of transformator lobe of the lung shields stacking technique, carries out stack, comprise the steps of from inside insulating part：
1）Insulating part is fixed on closed assembly platform, and insulating part open at one end block is made into insulating part with metal baffle
Inner chamber forms closing structure；
2）During stack, stalloy starts stack from non-central lateral central side, stalloy two ends is formed certainly with insulating part
Lock construction；One end positioning with the straightway of insulating part inner chamber and metal baffle end as stalloy, the stalloy other end press silicon steel
Leaf length is different and form lobe of the lung shape；
3）Resin is brushed in stack on the insulating part of stalloy bottom, according to insulating part cavity shape, using difference
The stalloy of length constitutes the profile of lobe of the lung shape, the full whole insulating part inner chamber of filling；
4）After the completion of stack, by semi-conductive tape electric iron, press on stalloy surface, and bulk silicon is made by ground strip
Steel disc bonding；
5）Resin is brushed on stalloy surface, resin is penetrated between silicon steel blade, will be stalloy bonding firm；
6）With insulating part cover closure insulating part inner chamber, riveted with screw rod, form lobe of the lung shielding, lobe of the lung shielding is made in upset
During, shielding stalloy can not depart from from insulating part.
The insulating part, is transformer body insulating supporting plate and insulating press boards.
The positive effect of the present invention：High-power transformer device body end profile shielding structure is shielded using lobe of the lung shape, i.e., in device body
Insulating support plate and insulating press boards are internally embedded stalloy；Lobe of the lung shape inner chamber is processed into, stalloy is piecemeal in insulating part
Stack is carried out, and the profile of lobe of the lung shape, the full whole insulating part inner chamber of filling is constituted using the stalloy of different length.Transformer body
End is arranged in insulating press boards and supporting plate using lobe of the lung shape shielding stalloy, and effectively solving end turn leakage magnetic flux simplifies and becomes
The overall shielding construction of depressor, shield effectiveness are more preferable.
