Abstract
The utility model relates to a power transformer comprising an iron core, a primary winding, a secondary winding and a winding column, wherein the primary winding and the secondary winding are wound on the winding column and connected with wiring terminals, at least two turns of the primary winding and the secondary winding are arranged, each turn comprises at least two coils, and ventilation gaps are arranged between each two turns. The power transformer improves the heat dissipation effect of the power transformer, ensures that the power transformer can operate safely, normally and efficiently, can lower wire diameters of the windings, and therefore lowers cost.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of power transformer.
Background technology
Power transformer is one of capital equipment of power plant and electric substation.The effect of transformer is many-sided, can not only boosted voltage electric energy be delivered to the electricity consumption area, can also be lower voltage use voltages at different levels, to satisfy the needs of electricity consumption.In a word, boost and all must be completed by transformer with step-down.Transmit in the process of electric energy in electric power system, will inevitably produce voltage and the loss of power two parts, voltage loss and voltage are inversely proportional to when carrying same power, square being inversely proportional to of power loss and voltage.Utilize transformer to improve voltage, reduced the power transmission loss.
Transformer is comprised of the two or more coil windings on same iron core, between winding is contacting and by electromagnetic induction principle work by alternating magnetic field.Coil windings of the prior art generally adopts the winding method that closely fits together continuously, causes its caloric value large, and radiating effect is bad.The load carried ability of power transformer depends primarily on the temperature of itself, in the course of the work, as long as be no more than the maximum temperature of operation, power transformer just can keep the operating state of Maximum Power Output, so the quality of transformer heat radiation directly affects its operating state.
Summary of the invention
The utility model proposes a kind of power transformer for above-mentioned deficiency of the prior art, has solved the bad problem of radiating effect in the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
Comprise iron core, winding, secondary winding and a wrapping post, be wound around winding and secondary winding on wrapping post, winding and secondary winding all are connected with binding post; A described winding and secondary winding are set at least two circles, and every circle comprises two coils at least, is provided with ventilation gap between circle and circle.
The ventilation gap interval setting of a described winding and secondary winding.
The utlity model has following advantage:
By the structure such as ventilation gap is set, improved the radiating effect of transformer, guaranteed that power transformer safety is normal, the high-efficient and lasting operation, and can reduce winding wire diameter, thus reduce costs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, iron core, 2, windings, 3, secondary winding, 4, wrapping post, 5, binding post, 6, ventilation gap.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe concrete structure of the present utility model in detail.
Embodiment
As shown in Figure 1, comprise iron core 1, winding 2, secondary winding 3 and a wrapping post 4, on wrapping post 4, winding 2 of winding and 3, windings 2 of secondary winding and secondary winding 3 all are connected with binding post 5; A described winding 2 and secondary winding 3 are set at least two circles, and every circle comprises two coils at least, is provided with ventilation gap 6 between circle and circle; The ventilation gap 6 intervals settings of a described winding 2 and secondary winding 3.
Claims (2)
1. power transformer, comprise iron core, winding, secondary winding and a wrapping post, is wound around winding and secondary winding on wrapping post, and winding and secondary winding all are connected with binding post; It is characterized in that a described winding and secondary winding are set at least two circles, every circle comprises two coils at least, is provided with ventilation gap between circle and circle.
2. power transformer according to claim 1, is characterized in that the ventilation gap interval setting of a described winding and secondary winding.
