Structural Features
Iron core: The magnetic material of iron core uses amorphous alloy. Since the
amorphous alloy does not have a crystal structure and has a soft
magnetic characteristic, the area of the hysteresis loop is very
narrow, the magnetization
power is small, the electrical resistivity is high, and the eddy
current loss is small, so the no-load loss and no-load current of
the transformer made of this material are used. very low. The core
is composed of four separate core frames in the same plane
to form a three-phase five-column type. It must be annealed, and it
must have a cross-barrier joint with a rectangular cross-sectional
shape.
Coil: In addition to using low-voltage windings (160kVA or less) with
copper conductors, a cylindrical structure made of copper foil is
generally used; high-voltage windings use a multi-layered
cylindrical structure to balance the winding ampere distribution
and magnetic flux leakage. High-voltage and low-voltage windings
are wound together with wire tension devices to form rectangular
coils, and the coils are solidified by hot-pressing and shaping to
enhance the mechanical strength of the windings and the ability to
withstand short circuit.
Oil tank: It adopts a beautiful full-sealing and maintenance-free corrugated
structure. Through advanced oil tank production technology,it
undergoes strict pressure...
