TFW series three-phase brushless excitation synchronous alternators
by introducing and developing on foreign advanced technology of
well-known alternators, are our newly developed products, The
generator set by coupling the alternators with engine are mainly
designed to serve as power generating unit in national defence ,
post and telecommunications, hospital, hotel, market and factory as
electric appliances or standby power. The alternators are made as
per standard JB/T3320.2-2000 and in conformity to IEC34-1. Being
tested by national authority department, the generator’s
performance achieves advanced international level .The
characteristic of alternators see as the followings:
1. Blushless, self-excited, insulation class H with high
temperature 180℃, so can reliablly run in bad conditions .
2. Steel welding frame, casting end bracket, the alternators have
two constrution of two-bearing and single-bearing;
3. Stator winding’s pitch is 2/3, the output voltage wave is
excellent;
4. Fine dynamic characteristics when load or unload suddenly;
5. Generally the alternators are two-bearing construction, also can
produce for single-bearing construction;
6. TIF<50, THF<2%, the alternators with high quality of AVR
have excellent properties;
7. 12 leads are suit for different connections, generally the
output voltages have: 400V/200V---50Hz and 480V/240V---60Hz;
8. The units can run at 50Hz and 60Hz;
9. The units can run at single phase by changing the output
connections, but the power at single phase only is about 60% of
three-phase’s power;
10. Standard drip-proof type is IP21, if our customer requires that
IP22 or IP23 are also produced; But the power will be reduced for
5% at IP23;
YHG series brushless three phase synchronous alternators are the
newest productsYHG series generator’s construction and shape are
different from TFW2 series generaror, these are the most different
between YHG and TFW2. YHG series alternators are designed to meet
market’s requirement.
The requirements for environment:
1. Altitude: not exceed 1000m.
2. Cooling air temperature: 258~313K(-15 ~40℃ ).
3. Relative air humidity: not exceed 90%. |
