3-1-11 Stator Iron Core Overheat
CAUSE REMEDY
Stator voltage too high operation, and iron core loss
increasing results in iron core overheat. Adjust generator voltage for keep rated voltage
operation.
Stator winding temperature high, the heat conduct to
the iron core. If the stator temperature is too high at rated
condition, should lower the generator load.
Rotor exciting current is too big, and rotor winding
temperature too high, heat conduct to the stator iron
core.
Adjust generator load to make the power not out
of the specified valve.
Generator operating with load at low speed, and heat
dispersion condition poor result in iron core heating.
Adjust engine speed for good ventilation.
Stator and rotor iron core partly friction result iron
core heating. Grind the rotor iron core arc to remove iron
friction.
