Versatile Amorphous Oil-immersed Transformer
By using the amorphous alloy with outstanding magnetic permeability, it can be used as the core material of transformer, and the loss value can be very low. However, it has many characteristics, which must be guaranteed and considered in design and manufacturing. The main body reflects the following aspects:
(1) The hardness of amorphous alloy sheet material is very high, and it is difficult to cut with conventional tools, so the design should consider reducing the shear amount.
(2) The single sheet thickness of amorphous alloy is extremely thin, and the surface of the material is not very flat, so the core filling coefficient is low.
(3) Amorphous alloys are very sensitive to mechanical stress. In the structural design, the traditional design scheme with iron core as the main bearing structure must be avoided.
(4) In order to obtain excellent low loss characteristics, amorphous alloy iron chips must be annealed.
(5) From the electrical…
