The STC generators are to be used in town,the countryside,
worksites,mountain districts and pasture lands as a electric
power source for lighting purpose.It can also be used as a
reserved power source for emergent case.The generators are of
dripproof with rotary field type and with the adoption of
harmonic excitation system, that allow your easy operation and
simple maintenance.
The generators are of three-phase four wire type,making use of
start connection with neutral point.The rated line voltage is
400V,phase voltage 230V,frequency 50Hz,power factor 0.8(lag).It
can provide 60Hz and the other voltage's generator according to
necessary.They can be coupled with a prime mover directly or
through v _belt,making right or reverse continuous rotation at
the rated speed.
When the revolution slip of prime mover is 3% and load varies in
the range of 0 100%,cos¦Õ,1.0
0.8they give good constant voltage.
After sudden change(increase or decrease) of load the generators
will soon return to their normal working state. Without any
starting devices the generator can directly start an unload
squirrel cageinduction motor. |
