Embodiment
embodiment 1
Ask for an interview Fig. 1 and Fig. 2, a kind of power transformer, include iron core, coil; It is characterized in that described iron core is made up of the first iron core column 11, second iron core column 12, the 3rd iron core column 13, upper yoke 21, lower yoke 22, upper yoke and lower yoke are all in-line; First, second, third iron core column be arranged in parallel, be not in contact with each other and length is equal, first iron core column, the second iron core column, upper yoke, lower yoke form the first appearance coil bore 31, second iron core column, the 3rd iron core column, upper yoke, lower yoke form the second appearance coil bore 32; First, second, third iron core column is fixed and is positioned at the top of first, second, third iron core column by upper yoke, and first, second, third iron core column is fixed and is positioned at the below of first, second, third iron core column by lower yoke; Iron core is integrated casting formation; Coil is made up of the first compound winding 41 and the second compound winding 42, and the first compound winding is coated on that the first iron core column is outer and a part is arranged in the first appearance coil bore, and the second compound winding is coated on that the 3rd iron core column is outer and a part is arranged in the second appearance coil bore; First compound winding is made up of the first high pressure winding of mutually insulated and the first low pressure winding, and the first high pressure winding and the first low pressure winding are all coiled into by enamelled wire; Second compound winding is made up of the second high pressure winding of mutually insulated and the second low pressure winding, and the second high pressure winding and the second low pressure winding are all coiled into by enamelled wire; Enamelled wire in described first high pressure winding and the second high pressure winding is all made up of B alloy wire and the wire enamel that enveloped by B alloy wire; Enamelled wire in described first low pressure winding and the second low pressure winding is by copper wire or B alloy wire and formed by the wire enamel that copper wire or B alloy wire envelope.
A kind of power transformer described above, it is congruent for it is characterized in that described first appearance coil bore and second holds coil bore.
A kind of power transformer described above, is characterized in that the material of described iron core is silicon steel.
A kind of power transformer described above, is characterized in that described B alloy wire is aluminum-alloy wire or Mg alloy wire or copper alloy silk or aluminum-magnesium alloy wire.
A kind of power transformer described above, is characterized in that the material of described wire enamel is polyurethane-type or polyester-type or polyester-imide type or polyamidoimide type or polyester-amides imine.
In the utility model, because iron core is that one casting forms, compared with superposing with silicon steel sheet of the prior art the iron core that formed, avoid the air gap losses because the gap in iron core produces, and eliminate assembling procedure, save corresponding cost of labor, and do not need superpose after again with glue class bonding, bake matters, save cost of labor and make core specification unify, the significant change of core dimensions can not be caused due to man-made assembly; In addition, because iron core is integral type structure, the magnetic hysteresis loss in iron core and eddy current loss are greatly reduced; Because transformer is when electric power is applied, usually the effect of power delivery is born, namely energy is delivered to the low pressure winding of low-voltage, high electric current from the high pressure winding of high voltage, low current, therefore, in high pressure winding side, the enamelled wire adopting B alloy wire conductor to form, such that transformer weight is lighter, heating is less, cost is lower; Therefore transformer cost is lower.Transformer in the utility model with adopt in prior art the stacked formation of silicon steel sheet iron core transformer compared with, the efficiency of transmission of electric energy brings up to 99.84% ~ 99.45% from 98.36%, and useful life extends 3% ~ 6%.
