10kV Oil Immersed Off - Load Tap Changer Power Distribution Transformer
General:
11KV class transformers are widely used in power transmission and distribution stations, industry plants, Generation Set-up Unit (GSU). They have the characteristic of high efficiency, low loss and maintenance free.
Structural Features :
► Iron core
The iron core is made of cold rolled grain oriented silicon steel
sheet. Laminations are cut to length on GEORG cut-to- length line
with step-lap cut and automatic stacking functions. The multi-step
lamination structure can reduce the loss and noise .The steel sheet
in the core limbs and yokes are clamped together by glass-epoxy
bonds.
► Winding
High quality enameled or paper covered copper is used as conductor,
the winding was made as drum type, spiral type, improved spiral
type, continuous type and interleaved type to ensure the insulation
strength. Standard tapings are ±2*2.5%of the HV winding.
► Tank
The tank, cover and the conservator are
made by corrugated steel plate .For the small transformers, we use
a deep tank and a cover, but for larger transformers, we
manufacture bell type .The corrugated construction are a effective
way for oil cooling.
► Insulation oil
The tanks are filled with high quality grade mineral oil as per
IEC296 and it is PCB and PCT free. The oil is used to help cooling
the transformer. It is also used provide part of the electrical
insulation between internal live parts.
►Tap changer
Tap changers are used to regulate the output voltage of the
transformers to required levels .We achieve this by changing the
ratios of the transformer on the system by altering the number of
turns in the HV winding .Tap changers can be on load (OLTC) or off
load(OCTC).
► Assembly
The core and the windings assembled together from the active part
of the transformer. The active body assembled with multi-windings
and identical pressure dry method adopted, effectively improved the
electrical strength and the ability to short circuit withstanding
