300kva Three Phase Pad Mounted Oil Type 12470v To 208v Step Down Transformer
Performance
1) The structure is compact and reasonable, and the volume is
small, which is only about one-third of the European-style box
change of the same capacity;
2) Fully sealed, fully insulated structure, no need to set up
safety barriers, and reliable guarantee for personal safety;
3) There are a variety of power supply schemes for users to choose
from, which can adopt terminal power supply and realize ring
network or dual power supply;
4) S11 oil-immersed power transformer is adopted, which has low
loss, low temperature rise and strong overload capacity;
5) Double fuses (backup protection fuse + plug-in fuse) are used
for protection, and the plug-in fuse fuse has the current and
temperature dual sensitivity characteristics to ensure the safe and
reliable operation of the product;
6) The 200A cable connector can be plugged and unplugged under
load, and can be operated as a load switch in an emergency. It also
has the characteristics of an isolating switch.
7) The winding adopts Dyn11 connection and the iron core adopts a
three-phase four-column structure, so that the product can run
under any asymmetric load, and the neutral point does not drift,
the voltage is stable, the power supply quality is high, the
cabinet heats up, the noise is low, and the lightning protection
performance is good ；
8) The cabinet adopts anti-corrosion design and special spray paint
treatment, beautiful and novel, suitable for various environments,
and achieve the effect of beautifying the city.
