10 KV 30-2500 KVA High Voltage Power Three Phase Transformer
30-2500 KVA High Voltage Power Three Phase Transformer from China
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.
