Over the past several thousand years, the metals of alloys used by the human beings are all those materials with crystalline structure, where the atomic three-dimensional space is provided with ordered arrange to form a periodic lattice structure.
When the amorphous alloy is rapidly cooled from the liquid state, because it can not crystallize in time and then will remain the liquid atoms in the condensed state of disordered arrangement at room temperature or low low temperature, the atoms will not be arranged in long-range ordered, periodical and ruled state but in long-range disordered state. The birth of amorphous alloys is also known as a revolution in metallurgy materials science.
2, Processing technology of the amorphous transformer core
By using the amorphous alloys with prominent magnetic properties to manufacture the core and applied to the transformer, it will be anticipated to obtain a very low core loss. However, due to itself properties, this kind of core have many characteristics and need our attention during the design and processing. Mainly reflected in the following aspects.
a) Cutting: Amorphous alloy materials are very hard and it is quite difficult to cut with conventional cutting machine. So it should be taken in account to reduce the shearing volume when design.
b) Stacking: the thickness of the amorphous alloy is extremely thin and the surface of the tape is not even, so the fill factor of the stacked core is very low;
c) Molding: Due to amorphous material are very sensitive to the mechanical stress, so it is necessary to take a special tightening measures in the production process.
d) Annealing: In order to reduce the core loss, annealing procedure is very important, and it is also the crucial technology in the whole process.
3, Structural features
Three phase five legs amorphous core is suitable for Dyn11 connection group transformer. The current design of existing core dimensions can meet the requirements regarding to our current assembly technology, facilities and craft ability during the amorphous transformer manufacturing.
By adopting the advanced distributed stacking structure in the core joint area, the stacked thickness normally less at least 7% compare to other competitors. And final reduce the whole transformer dimensions.
Lower exciting power could reduce the transformer noise during operation.
