Example, is explained in further detail the utility model.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
On the contrary, the utility model cover it is any be defined by the claims do in the spirit and scope of the utility model
Substitution, modification, equivalent method and scheme.Further, right below in order to make the public have a better understanding the utility model
It is detailed to describe some specific detail sections in the datail description of the utility model.Do not have for a person skilled in the art
The utility model can also be understood completely in the description of these detail sections.
There is no core pressing structure for triangular solid Wound iron-core transformer in the prior art, it is easily loose to will lead to lamination
The problems such as scattered, the magnetic line of force is unevenly distributed, and transformer noise is big, and transformer noload losses fluctuation is big, and iron core inserted sheet effect is bad.
The utility model embodiment provides a kind of core pressing structure of triangle open mouth three dimensional wound core transformer, such as schemes
Shown in 1 and 2, core pressing structure include for compressing the iron core pressing plate 1 of iron core, the iron core for fixing the iron core pressing plate
Folder and the iron core pressing plate insulation barrier 5 being set to below the iron core pressing plate 1 for insulation；
The iron core upper clamping piece uses channel steel structure, and the upper end of channel steel structure is fixedly connected with the iron core pressing plate 1, channel steel
The lower surface of the lower end of structure and transformer coil 9 contact and compress the transformer coil.
Further, the iron core upper clamping piece includes long axis upper clamping piece 7 and short axle upper clamping piece 8；By long axis upper clamping piece 7 and institute
It states short axle upper clamping piece 8 to be staggered, connects and composes the iron core upper clamping piece that shape is hexagon；The long axis upper clamping piece 7 and short axle
Upper clamping piece 8 is all made of channel steel structure.Preferably, the iron core upper clamping piece includes that long axis upper clamping piece 7 and short axle upper clamping piece 8 can be adopted
It is linked together with the mode of welding.
Further, the iron core pressing plate 1 uses strip plank frame, and quantity is three, each described iron core pressure
The both ends of plate are arranged on the long axis upper clamping piece of adjacent two.
