Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
By Fig. 1-2, provided, the utility model comprises housing, iron core, low pressure conductive foil winding and high-pressure conductive paper tinsel winding, housing 9 in-built cored 6, low pressure conductive foil winding and high-pressure conductive paper tinsel winding are housed on iron core successively, low pressure conductive foil winding is along long, to being uniform staggered with, to install around the composite construction forming by the elementary conductive foil 5 of multilayer and the first insulating barrier 3 on iron core, elementary conductive foil 5 is Copper Foil, aluminium foil or oxide-film aluminium foil around a kind of, on the surface of elementary conductive foil, there is insulating barrier, high-pressure conductive paper tinsel winding is long to be uniform staggered with the composite construction forming on low pressure conductive foil winding outside by the secondary conductive foil 7 of multilayer and the second insulating barrier 4 edges, secondary conductive foil 7 is Copper Foil, a kind of in aluminium foil or oxide-film aluminium foil, there is insulating barrier on secondary conductive foil surface, between low pressure conductive foil winding and high-pressure conductive paper tinsel winding, be provided with for insulating and leading to the oil duct 8 of oil cooling, oil duct 8 is connected with the conservator 10 that is contained in housing 9 outsides through pipeline.
For guaranteeing result of use, on described low pressure conductive foil winding, low-voltage lead 1a, the 1b being connected with elementary conductive foil 5 is housed, low pressure conductive foil winding can be drawn or be introduced by low-voltage lead 1a, 1b;
On described high-pressure conductive paper tinsel winding, high-voltage connection 2a, the 2b being connected with secondary conductive foil 7 is housed, high-pressure conductive paper tinsel winding can be drawn or be introduced by high-voltage connection 2a, 2b;
Described iron core is prior art, and described conductive foil winding according to actual needs, can, by three-phase high and low pressure conductive foil winding or two-phase high and low pressure conductive foil winding, provide the situation of 3 groups in Fig. 2.
Compared with prior art, the utlity model has following outstanding advantage:
1, adopt Copper Foil, aluminium foil or oxide-film aluminium foil to replace traditional aluminum steel or copper cash, increased the cross-sectional area of wire, electric capacity improves more than 25 times, reduces the direct current loss in winding, strengthens the overload capability of transformer;
2, with Copper Foil, aluminium foil or oxide-film aluminium foil, replace traditional aluminum steel or copper cash, dwindled the volume of coil, and then reduce core volume, therefore, reduced transformer noload losses, also reduced the noise of transformer;
