Traction Alternator ( DR101/03AZ replaceable with GTA17PB1 ) |
Traction Alternator DR101/03AZ meets the
requirements of high horse power Diesel-Electric
Locomotives of up to 3300 HP capacity, such as
those of Indian Railways. This Alternator is suitable
for rotational speeds up to 1100 RPM.
This Traction Alternator is a salient pole, 3-phase
star connected, separately excited, single bearing
machine, directly coupled to Diesel Engine.
Auxiliary Generator and Exciter mounted on
the gearbox of the Alternator are gear driven,
besides catering for Loco control system power
and Alternator field excitation requirements
respectively, act in tandem to crank Diesel
Engine. Power Take Off Unit, also mounted on
the Alternator gearbox, drives blower unit for
providing cooling air to the traction motors. Some
of the special features of the Alternator are:
- VPI of stator winding and rotor field coils in
solvent less resin of Class 200, to ensure void
free insulation.
- Brazed connections of joints of the stator
winding.
- Self ventilation with its own fan, thereby no
need of external source of cooling air.
- Alternator R, Y, B leads terminating in a terminal
box, to facilitate connections with the rectifier.
