30kV Oil - Immersed Transformer, Three Phases, Two Winding, Power
Oil-immersed type transformer features low noise, low loss,
rational structure, high quality material, scientific design,
strict production technology and advanced test method. The product
also has the following additional advantages:
1. High mechanic strength, great anti-short circuit capability,
excellent anti-lightning impulse capability and high reliability.
All these performance indexes rank first in the industry in China.
2. Excellent overload capability, capable of continuously working
under 110% rated load.
3. Low loss, energy-saving, economic and maintenance free.
4. Nice appearance, small size, less installation space occupation
and low engineering cost.
5. Each performance index and technical specification excels that
specified in China GB, international IEC and industrial standards.
6. Hermetically sealed corrugated tank structure is adopted, thus
to effectively prevent air corrosion to the oil and prolong service
lifetime of the transformer.
The core is manufactured with high quality cold rolled
grain-oriented silicon steel of high magnetic conductivity, and 45°
Mitring and steps overlapping structure is used for core
production, thus to effectively reduce no-load loss and no-load
HV winding is manufactured with high quality copper conductor,
adopting optimized structure to improve electric distribution.
Lightning impulse wave process is carried out for calculation and
analysis, thus to improve transformer's anti-lightning impulse
LV winding is manufactured with high quality foil conductor, so the
ampere-turn balance is excellent and the transverse magnetic flux
leakage is low. The anti-short circuit capability is thus greatly
improved. Oil conduit is rationally designed in the windings to
increase winding's heat dispersion surface, effectively reduce
temperature and improve transformer's overload capability.
This series products are mainly supplied with two specification: YW
I and YW
II:YW I is normal type, YW II is the type with pressure-relief
Effective caliber for oil spraying is Φ 25mm,open pressure is
---Visual window and connected f;ange have vert good qualified
Is safe and reliable,without any leakage.Before it is delivered out
from the factory,it
Will be tested rvder 200kPa pressure for checking its leakage.
