Special Features:
1.
Low partial discharge: the apparent discharge quantity is usually
less than 100pC;
2.
Low noise: Product of 63MVA or below 63MVA has a noise level less
than 60dB;
3.
Low loss: no-load loss is reduced by 20 percent compared with that
specified in national standards;
4.
High anti-short capability: the SFZ10-40000/110 transformer has
passed the short-circuit test carried out by China National
Transformer Quality Supervision Testing Center.
Winding:
The interleaved and continuous winding structure is adopted for HV
windings, thus to improve
the electric distribution and effectively improve the
anti-lightning impulse capability. Inner and
outer support strip structure is adopted. The support strips and
pads are all rounded to improve
insulation reliability. Oil-directing structure is adopted in the
winding, thus to reduce the hotspot
temperature and prolong insulation life.
Both the H.V and M.V. windings are usually provided with separate
voltage regulating windings,
so the ampere-turn of all the windings are completely balanced.
These can effectively eliminate
the axial electrodynamics force during external short circuit and
improve the dynamic stability
under external short circuit.
