Product DescriptionThe SZ, SFZ, SFS, and SFSZ series power
transformers produced by our company have a maximum capacity of
240,000kVA for a 110kV voltage class and 400,000kVA for a 220kV
voltage class.This series of products are power equipment with low
loss, low noise, low partial discharge, and strong short-circuit
resistance, independently developed by combining domestic and
foreign advanced technologies.The transformer can transform the
grid voltage into the voltage required by the system or load, and
realize the transmission and distribution of electric energy. This
series of products can be installed and used outdoors (or indoors),
and are especially suitable for operation in humid environments.
They are ideal power distribution equipment in factories, rural and
urban vast power transmission and distribution networks.Model
DescriptionTechnical parameters Product features and
advantageProduct features:1. The iron core is made of cold-rolled
grain-oriented silicon steel sheet, with 45° full oblique joints,
no middle hole and epoxy tape binding structure, and the iron core
surface is coated with iron core protective paint to reduce loss
and noise;2 .Using a new type of oil channel structure, high heat
dissipation efficiency, reducing the temperature rise of the
transformer and prolonging the service life of the transformer;3.
The box adopts a fully sealed structure of the corrugated oil tank
to prevent air and water from contacting the transformer oil,
reducing the aging degree of the oil. The service life of the
transformer is extended, and the volume change of the transformer
oil in thermal expansion and contraction is adjusted through the
elastic deformation of the corrugated sheet;4. The transformer is
equipped with pressure release safety protection. When the
transformer fails and the pressure is too high, it can be reliably
and safely through the pressure release valve release to prevent
the expansion of the accident.Product advantages:1. Strong
short-circuit resistance.Advanced calculation programs are used to
calculate the short-circuit condition of the transformer, and
analyze the force and deformation of each part of the coil under
the short-circuit condition. It can greatly improve the anti-short
circuit capability of the transformer.2. Low-lossoptimized
electromagnetic calculation, using multiple shielding methods to
control magnetic flux leakage, reduce load loss and avoid local
overheating.Cold-rolled lattice-oriented high-permeability silicon
steel sheets are selected, fully inclined STEP stepping joints are
adopted, and no holes and no iron yokes are stacked to reduce
no-load loss, no-load current, and electromagnetic noise.3. The
body of high mechanical strengthadopts the six-sided positioning
method, which can meet the transportation acceleration of not more
than 0.3g in the horizontal direction and not more than 0.15g in
the vertical direction. Product detailsProducts real shotA
