Description
Technical field
The utility model relates to a kind of transformer, particularly relates to a kind of many taps dry type isolating transformer.
Background technology
At present, the most of wire-wound cylindrical layer winding structure that adopts of many taps dry-type transformer, its winding forms by the electromagnetic wire coiling, there is certain defective in this structure: the ampere-turn unbalance factor of winding is bigger, when sudden short circuit, can produce huge axial force, damage coil easily, overall mechanical strength is poor, can cause under the serious situation burning.
The utility model content
The technical problems to be solved in the utility model provides a kind of many taps dry type isolating transformer, and the ampere-turn equilibrium rate is better, and exportable multiple voltage.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of many taps dry type isolating transformer comprises iron core, winding, secondary winding, a described described iron core of winding suit, and the described winding of described secondary winding suit,
A described winding and secondary winding are formed by the coiling of several layers conductor foil, are provided with insulating barrier between the described adjacent every two-layer conductor foil,
Described many taps dry type isolating transformer also comprises many tap leads device, described many tap leads device comprises some tap copper bars, described some tap copper bars are drawn from described secondary winding, and described tap copper bar is connected with conductor foil in the described secondary winding.
Preferably, the conductor foil in the secondary winding described in the utility model is pressed the segmentation of tap copper bar, and is connected to the upper and lower surface of corresponding tap copper bar in succession by argon arc welding.
Preferably, conductor foil described in the utility model is Copper Foil or aluminium foil; Described insulating barrier is formed by the coiling of F level DMD epoxy preimpregnation cloth.
As improvement, also be provided with the heat radiation air flue between a winding described in the utility model and the secondary winding.
Therefore compared with prior art, the utility model has following beneficial effect:
What winding of the present utility model adopted is paper tinsel formula structure, promptly constitute by conductor foil and insulating barrier, interlayer conductor contact-making surface is bigger and spacing is less, therefore higher turn-to-turn capacitance is arranged, and the voltage gradient in the winding distributes more even, approaching linear under surge voltage like this, so the ampere-turn equilibrium rate of winding is bigger, the short circuit axial force is very little, and anti-sudden short circuit ability is strong, has improved product quality; Many tap leads device that the utility model adopted in addition can be exported multiple voltage, is fit to different occasions, and is very easy to use.
