Technical Field

The utility model relates to a transformer field specifically is a double-deck vertical transformer integrated configuration.

Background

Most of the winding structures of the conventional vertical transformer are wound on a bobbin with the same framework, and the conventional structure often causes insufficient safety distance between a primary stage and a secondary stage under the condition that the space occupied by the transformer is limited. And the utility model discloses integrated configuration can be with elementary and secondary completely isolation, and also can keep apart between a plurality of secondary windings, can effectually play insulating effect, increase the effect of ampere distance, current conventional vertical transformer winding structure is mostly around on same skeleton bobbin, if there is the requirement of higher safe distance, the wire rod of higher safe specification is chooseed for use to the accessible, increase the magnetic core size, mode realization such as increase other insulating materials, but all can increase the transformer volume, if the output that the product needs is many, and safe distance requires highly, then the transformer volume can be very big. And the design adopts the utility model discloses three-layer composite structure's transformer can separate the coiling with a plurality of windings, and primary-secondary, secondary-secondary can both effectively separate, and safe distance is guaranteed, can also increase the output, saves space.
