capacity of the transformerThe transformer load capacity and
accident overloading capacity meet the requirement of GB/T15164
oil-immersed power transformer load guideTransformer structural
requirementsTransformer oil: insulation oil of transformer is 25#
transformer oil.Iron Core:The iron core is made of high quality
magnetic cold-rolled oriented silicon steel sheet with full oblique
joints at 45 degrees. The surface of the iron core is sealed with
special resin, resistant to moisture and stainless steel. The core
lamination adopts the latest step lamination method to reduce the
no-load loss and no-load current.Winding:The high and low voltage
winding of the transformer is made of high quality material, which
makes the winding ampere-turns balanced, has strong resistance to
short circuit, and reduces the eddy current loss of the
winding.Operation principleHigh pressure of 35 KV, D connection,
low voltage is 4 x 1.0 KV, using two groups of yanbian delta
connection, in addition, respectively is the delta connection and Y
connection to phase shifting transformer rectifier, yanbian
triangle phase-shifting Angle of plus or minus 15 degrees, a
24-pulse rectifier transformer combination, if delta connection and
low voltage transformer used Y connection to use, can be composed
of 12 pulse wave, two groups of yanbian delta connection can also
be used 12 pulse, low pressure 4 set of coils can be used at the
same time run 24 pulse wave respectively.Classification:1. By
phases: 1) Single-phase transformer: for single-phase load and
three-phase transformer group. 2) Three-phase transformer: used for
raising and lowering voltage of three-phase system. 2. According to
the cooling mode: 1) Dry-type transformer: natural cooling or fan
cooling by air convection, mostly used in high-rise buildings,
high-speed toll stations, local lighting, electronic circuits and
other small capacity transformers. 2) Oil-immersed transformer:
relying on oil as cooling medium, such as oil-immersed
self-cooling, oil-immersed air-cooling, oil-immersed water-cooling,
forced oil circulation, etc. 3. By use: 1) Power transformer: used
for the rise and fall voltage of power transmission and
distribution system. 2) Instrument transformer: such as voltage
transformer, current transformer, measuring instrument and relay
protection device. 3) Test transformer: can produce high voltage,
high voltage test for electrical equipment. 4) Special
transformers, such as furnace transformers, rectifier transformers,
adjusting transformers, capacitive transformers, phase-shifting
transformers, etc. 4. According to winding form: 1) Double-winding
transformer: used to connect two voltage levels in power system. 2)
Three-winding transformer: It is commonly used in regional
substation of power system to connect three voltage levels. 3)
Autotransformer: A power system for connecting different voltages.
It can also be used as a common boost or drop transformer. 5.
According to the form of iron core: 1) Core transformer: power
transformer for high voltage. 2) Amorphous alloy transformer:
Amorphous alloy iron core transformer is a new type of magnetic
conductive material. Its no-load current decreases by about 80%. It
is an ideal distribution transformer with energy-saving effect. It
is especially suitable for low load ratio areas such as rural power
grid and developing areas. 3) Shell transformer: special
transformer for large current, such as furnace transformer, welding
transformer, or power transformer for electronic instruments,
television, radio, etc. Product Show: /* January 22, 2024
