Embodiment
Referring to figs. 1 through Fig. 5, a kind of big electric current output transformer comprises the former limit winding that is wrapped on the iron core and is wrapped in the outer secondary winding of described former limit winding, and described secondary winding is assembled by following independently parts:
First pedestal is provided with arc groove 9, and this arc groove 9 is divided into first secondary 2 and columniform first center pillar 4 with described first pedestal.
After described first pedestal and the assembling of second pedestal, first center pillar 4 interts at the die of described second center pillar 3, and the top of first center pillar 4 exceeds the top of described second center pillar 3; Constitute an annular containing cavity 5 for ccontaining described former limit winding between the outer wall of described arc groove 9, half-cylindrical breach 8 and second center pillar 3, by the insulating cement isolated insulation, described second center pillar and first center pillar are by insulating cement or gap isolated insulation between described first pedestal and second pedestal; The top of the top of described second center pillar and described first pedestal is by the copper coin electric connection, draw by copper coin on the top of the top of described second pedestal and described first center pillar becomes the output bus, first pedestal and second pedestal are provided with some screws 7, and copper coin is just fixed by the screw that is installed in the screw 7.
First center pillar of the present utility model is cylindrical, and second center pillar is the pipe shape, and the surface area of first center pillar, second center pillar is bigger, can bear bigger electric current, and caloric value and own loss are little, can accomplish bigger power.
The secondary winding is divided into first pedestal, second pedestal, three independent sectors of second center pillar, can adopt method for turning processing, also can adopt injection moulding or powder metallurgy process to make, the convenient making and assembling, particularly the volume of second pedestal, second center pillar is less, in turning process, can utilize rim charge to make, reduce production costs.
First secondary 2 and columniform first center pillar 4 constitute the first circle secondary winding, second pedestal 1 and second center pillar 3 constitute the second circle secondary winding, the different name end of two windings connects by copper coin, then, the free end of the free end of the first circle secondary winding and the second circle secondary winding is drawn by copper coin, just forms the bus of secondary winding.Change the output voltage of transformer if desired, under the situation that former limit winding remains unchanged, can be by changing the number of turn of secondary winding, namely changing no-load voltage ratio realizes, in like manner, except the secondary winding at two ends, the different name end of all secondary windings once links to each other and forms open circuit, then the free end of the secondary winding at two ends is drawn by copper coin and get final product, the periphery of described first center pillar 4 is 32mm to the distance of arc groove 9 and half-cylindrical breach 8 sidewalls, can accomplish output frequency up to 30KHz, the height of first center pillar 4 is 63mm, and the benefit of this design is to accomplish that voltage output reaches more than the 60V.
Second center pillar, first center pillar adopt the nested installation method of concentric, are convenient to expand the secondary winding quantity of transformer.
Because when changing electric pressure, former limit winding is constant, just the secondary winding changes, the size of transformer can not have greatly changed substantially, therefore, second center pillar goes for the transformer of different secondary windings, has versatility, can realize large batch of production, as make the transformer of 4 circle secondary windings, second center pillar is constant, in other three center pillars, two center pillars adopt tubular structure, and middle one is adopted column structure, and other three center pillars of assembling back adopt the concentric mode to be nested in the second center pillar die and get final product.
