Reliable And Safe 50 Kva Dry Type Transformer Used For Airports And
Dry Type Transformer Introduction
A. the material of iron corn is high magnetic flux cold rolled grain
oriented silicon steel sheet, of which the thickness
is less than 0.3 mm. Meanwhile, Protective resin covered on the
surface of iron core for Moisture proof and rust proof.
B. The structure of low voltage winding is Cylindrical, which is made
by copper foil. The high voltage winding has
the structure of Multi-storey. The style of designing can improve
the mechanical strength and the ability of Anti short circuit.
C. The cooling system equips low noise fans adapted by Temperature
Controller to add 40% more capacity for the Transformer.
D. the Protection Level of the transformer executed by the standard
of IP20 can defense the transformer from any items
which the diameter is greater than 12 mm. To meet the needs of
clients, the protection level can reach to IP23,
which can defense ≤60 degree angle water falls.
E. No load loss and load loss meet the standard of GB/T 10228-2008,
however, the no load loss of SC(B) 10 is lower 10%
of the standard of GB/T 10228-2008 and the load loss is lower than
5% of GB/T 10228-2008.
Applied Standards : GB/T 10228, GB1094.11, IEC60076-11, DIN42523
Through the "three-phase five-limb" structure, frame structure and
the rational design, the core is protected to prevent the core from
being affected by externally applied forces and thus to ensure its
no-load performance. During core mould designing, computer
simulation analysis is carried out for precisely calculating the
vibration frequency and scale, thus to avoid cavity resonance
produced by core structure during operation. During production,
special vibration-reducing and noise-decreasing materials are used.
All these measures are for reducing the transformer's noise during
HV winding is manufactured with high quality copper wire,
reinforced with glass fiber and being casted with epoxy resin at
vacuum state with pressure, having the resin fully impregnated into
the coils in the most professional imported equipment. Therefore,
product's partial discharge is especially low, for example,
transformer of 10kV-level has only a partial discharge less than 5
pC. During the HV winding design, rational structure is adopted to
improve the electric distribution. With the lighting impulse wave
simulation calculation and analysis being carried out through
special auxiliary computer software, product's anti-lightning
impulse capacity is greatly improved.
LVwinding (with the rated power equal to or higher than 200kVA) is
manufactured with high quality foil conductor, resulting in
excellent ampere-turn balance, low transverse magnetic flux leakage
and higher anti-short circuit capability. By designing reasonable
air conduit in the windings to increase the heat-dispersion
surface, transformer's temperature rise is effectively controlled
and the overload capacity is greatly improved.
