CHARACTERISTIC
Dingol generators have the features
and advantages such as with compact design(small in sizes
and light in weight) and large power output.
Dingol generators can be powered
by diesel engines from any of the world's leading manufacturers.
Up to now, these generators have been widely used in ships,
oil fields, trains, telecommunications and high-layer buildings.
The brushless gene,rators of
power range covers ratings from 5KVA to 1000KVA. The generators
are normally available in either of two versions-400V, 50Hz
or 450V, 60Hz although otherratings up to 660V are also available.
Short time load rating of up to 150% of the rated current
in 2 minutes.
The generators can carry a load of 110% for one hour in six.
ELECTRIC ADVANTAGE
Regulation accuracy
when no load to full load.
AVR WSR31¡¡£¡¡¡À0.5%
External and internal
voltage control range: £¾ ¡À 10%
Dynamic voltage characteristics
The transient dip in voltage when rated load is placed on
the alternator at 0.8 power factor is 20%Un.The recovery time
is between 0.2 and 1.0 second.
Unbalanced load
The alternators permit an unbalanced load of 25% rated current.
The deviation of line voltage is less than 5%.
The generators are including main alternator, exciter, excitation
system. Brushless and constant voltage are available on product
design.
All windings are made of class
H copper wire and class H insulating materials. The standard
insulation used a special epoxy resin impregnation process.
The insulation system of the windings conforms to the requirements
of temperature class H. The insulation is resistant to moisture,
oil vapour, contamination and corrosive sea air.
Alternator's frame is made of
6mm steel plate. End bracket is made of high strength casting.
These result in alternator strong and pleasing to the eye,
vibration level derated.
Small measurement, light weight,
simple construction modern CAD optimum design.

Supply automatic voltage regulation AVR with high reliability.
Permanent Magnet Generator(PMG) can
meet special place leading non-line facility and alternating
load.
Main stator windings are 2/3 pitch,
eliminating third harmonic neutral currents. One slot stator
skewing further reduces harmonics.
The generators are available in voltage
range up to 660V, according to connection change for 12 leads
of main stator.
General international SAE disc coupling
for single bearing generator. Ensure the concentricity of
gensets. Simple installation and maintenance.
Radio interference suppression
The alternators are supplied with interference suppression
grade N to VDE 0875.
Parallel operation
During the usually short period required for no-break load
transfer the alternators can be operated in parallel regardless
of design variant and manufacturer.
The reactive load sharing is assured by a droop compensation
device. Thus equipped, the alternators are suitable for parallel
operation with other alternators having the same voltage droop
or with a supply system. |
