Abstract
The utility model relates to an electronic conversion device applied to heating or illuminating devices, in particular to a low-voltage high-current transformer, which comprises lead wires, silicon-steel sheet iron cores, a support, nuts, screws, winding coils, insulating bakelite plates, heat-radiating air ducts and copper bars. The lead wires are lead out from the support fixedly through the nuts; the winding coils are of a square cake-shaped structure and are internally filled with the silicon-steel sheet iron cores, and the winding coils in each layer are spaced by the insulating bakelite plates to form one heat-radiating air duct; the winding coils in each layer are stacked in parallel connection manner and are output from the copper bars in a wiring manner; and the insulating bakelite plates are arranged between the screws for fixing the support and the winding coils. According to the utility model, by means of stacking the square cake-shaped coils in parallel connection manner and outputting the coils from the copper bars in a wiring manner, simplicity, convenience and feasibility are achieved for winding; and the heat-radiating air ducts are formed among the winding coils, so that the work temperature of the transformer can be reduced effectively, and a ventilation effect and a heat radiation effect are achieved.
Description
Technical field
The utility model relates to a kind of electronics converting means for devices such as heating heating or illuminations, specifically relates to a kind of low-voltage high-current transformer.
Background technology
Transformer Winding adopts copper cash or aluminum steel more in the industrial production, after the insulating barrier wrapping, twines according to the umber of turn that meets voltage request.Transformer capacity is larger, and operating current is larger, and the winding conducting wire sectional area is corresponding increase also.When voltage lower (voltage is lower than 100V), electric current large (between the electric current 300A-3000A), the general employing is divided into stranded conductor with heavy in section wire and links up, and the transformer wire diameter requires larger.When to stranded conductor coiling in parallel, make every effort to reach each burst conductor length consistent and strand between induced electromotive force equate, to sum up cause complex process and the difficulty of Transformer Winding.Simultaneously, larger electric current produces a large amount of heats easily through transformer, so heat dissipation ventilation also is the problem that low-voltage high-current transformer need to be considered.
Summary of the invention
For above-mentioned present situation, the purpose of this utility model provides a kind of low-voltage high-current transformer, and winding coil adopts square cake formula structure, make things convenient for coil winding, leave heat dissipation wind channel between the line disc coil, heat dissipation ventilation is effective, can effectively reduce the working temperature of transformer.
The technical scheme that the utility model adopts is: a kind of low-voltage high-current transformer comprises wire, silicon sheet core, support, nut, screw, winding coil, insulated electro plank, heat dissipation wind channel and copper bar.Described wire is fixedly drawn by nut from support; Described winding coil is square cake formula structure, and the inner silicon sheet core of filling separates with the insulated electro plank between every layer of winding coil, forms a heat dissipation wind channel; Described every layer of winding coil stacks in parallel, and exports from the copper bar wiring; Be provided with the insulated electro plank between described support bracket fastened screw and the winding coil.
The beneficial effects of the utility model are: winding coil adopts square cake formula structure, stacks and exports from the copper bar wiring with parallel way, and coiling is simple and easy to do like this; Separate the formation heat dissipation channel by the insulated electro plank between the winding coil, can effectively reduce the working temperature of transformer, play the effect of ventilation and heat.
