Characteristics
1. core
High quality cold-rolled grain oriented silicon steel sheet is
selected as the core, the full inclined pore free structure is
adopted, and the low magnetic steel plate is used as the pull plate
to firmly connect them upper and lower clamps with the core into a
steel structure, so as to obtain less no-load loss and lower noise.
The burr of silicon steel sheet shear port shall not be greater
than 0.02mm. The no-load performance index is better than the
national standard of China.
2 coil
According to the capacity of the transformer, the winding adopts
cylinder, spiral, continuous and other structures. For the winding
of 110kV UHV Transformer, the winding adopts tangle or inner screen
structure, so as to effectively improve the distribution of impulse
voltage. The conductor adopts transposed conductor or composite
conductor, so as to reduce the additional loss of the winding, and
uses computer simulation to calculate the impact of electric field
and winding The characteristics ensure the excellent electrical
characteristics and impact strength of the winding, and the
effective measures are adopted in the process to ensure its safe
and reliable operation.
3 fuel tank
The oil tank adopts a flat top bell jar structure, and the box wall
is welded with folded plate type reinforcing iron, which improves
the mechanical strength of the oil tank. In order to reduce the
stray loss of the transformer, the inner wall of the large
transformer is equipped with a magnetic shield.
