IEC600762. Voltage Grade: 6kv, 10kv, 11kV, 13.8kv, 15kv3. Voltage
Regulation Mode: Off circuit tap changing or on load tap changing4.
Tapping Range: ± 5%, ± 2× 2.5%, ± 4× 2.5% or others5. Frequency:
50Hz; 60Hz6. Phase: Three phase7. Connection Sign: Yyn0, Dyn11,
Dyn5 or others8. Short Circuit Impedance: Standard impedance (For
details see technical data sheet)Main characteristics of
oil-immersed transformer:1. High short-circuit resisting ability
and fine mechanical performance2. Low power consumption, low
partial-discharge and low noise3. No leakage, free of core and
winding body lifting and no maintenanceMain technical points of
oil-immersed transformer:1. Scientific computing method:Adopt
advanced computing software for electromagnetic heat and mechanical
power to calculate the distribution of electromagnetic field and
magnetic leakage, choose insulation tolerance and analyze wave
process; The software is used for simulation design of plane and
three-dimensiona dynamic model, which guarantees the products a
reliable performance and a rational structure.2. Rational array of
structure:According to the computing result, choose rational
insulation structure, wire specification and magnetic flux
density.Adopt magnetic screen for oil tank. Calculate the natural
vibration frequency of drawplate and iron core. Adopt multistage
step lapped joint fully-oblique structure...Reduce on-load power
consumption and noise. Increase the short circuit resisting ability
by adopting round bar and cardboard sleeve.Reduce the
partial-discharge by applying rounding process on the fringes of
insulation parts and metal parts and metal parts inside the
transformer.3. Advanced processing methods:Cut the iron core
automatically, so the precision is high and the burr is very
small.Adopt non-overlapping upper yoke processing.Apply double-H
setting glue on the surface, Coil the wire vertically, and a
numerical control tension device is needed.Set-assemble is adopted
for the body of transformer. Integral preassemble is adopted for
the wire lead.Full automatic control gas-kerosene drying process is
adopted for the body of transformer. Preassemble is adopted for
general assembly.4. Perfect quality assurance system: Control the
quality of products according to the ISO19001 quality standards.5.
Systematic data management: ERP&PDM data management programs
are adopted during the whole process from sale to leaving
