50/60Hz 34.5kV 3150kVA three phase cast resin dry type
transformerTransformer Advantage1. Low loss, low noise, low partial
discharge.2. Strong anti-short circuit capability and high
anti-lightning impact level.3. Excellent moisture resistance for
operation at 100% relative humidity.4. Strong overload capability
for long-term operation at 150% loading. Transformer Test ReportFor
all transformers developed and supplied by Pearl Electric, Type
tests and Specials Tests have been carried out in
internationally-recognized independent test lab, and test reports
have been obtain, including:1. C2/E2/F1 test report for cast resin
dry type transformer2. Aging test report for cast resin dry type
transformer3. Aseismatic report for cast resin dry type
transformer4. Type and special test reports for class 1E dry type
transformer for nuclear power station application5. Type and
special test reports for various traction/excitation trasnformers6.
. Type and special test reports for amorphous alloy core dry type
transformer7. Type and special test reports for three-phroof
(salt-fog, midew, humdid-heat) performanceTransformer
ChracteristicsTransformer Core1. The core is made of high quality
grain-oriented cold-rollled silicon steel of high magnetic
conductivity, by using 45°five-step overlapping method to reduce
the no-load loss and no-load current.2. Simulation analysis method
is applied for the core design, thus to precisely and effectively
calculate the vibration frequency and scale.3. Flexible connections
are adopted between the core and coils, core and clamps. With these
measures, transformer's noise level has been improved by 10-15dB
over the conventional products.Transformer WindingsLV windings1.
For LV windings above 400 kVA capacity, superior foil conductors
are adopted for winding manufacturing, thus to obtain better
amper-turn balance and less transverse magnetic flux leakage, and
finally to greatly improves transformer's anti-short circuit
capability.2. By reasonably designing the oil passage within the
winding, winding's heat dispersion effect is greatly increased.
Thus the reasonable design has decreased temperature rise and
improved products' overload capability.HV windings1. HV windings
are manufactured with superior wire conductors, insulated
reinforced with fiber glass.2. The HV windings are cast under
vacuum and high pressure conditions in Germany HUBERS vacuum Cast
Machine, resulting the best resin penetration and very low partial
discharge( partial discharge for 11kV product could be lower than
5Pc).3. Optimized structure is adopted for HV windings to improve
transformer's electric field. Lighting impulse simulation
calculation was adopted for winding model design, thus to
substantially improve product's anti-lighting capability.PEARL
