Reason and elimination method in 2019 - tractor generator overheating
04 -
24 a, fault signs: tractor generator casing when the temperature is very high, more than 60 degrees, touch feel hot.
Second, the cause of the problem: the bearing oil shortage or gap is too small, result in bearing friction produce overheating phenomenon;
Bearing severe eccentric wear or damage, as well as the rotor shaft bending or floppy disk error, cause scratches the rotor pole and stator core, namely sweep chamber;
Stator winding interturn short circuit, open circuit or wrong wiring, make the internal short circuit current generator;
Generator overload operation.
Three, elimination method: regular maintenance of generator, found that lack of oil in a timely manner to add compound calcium base grease, general two-thirds full of bearing cavity;
Check shaft bending, bearing whether eccentric wear, replace the bearing when necessary, correcting the rotor shaft, core, etc;
Use multimeter method or try lamp method to check if the stator coil short circuit or open circuit, if yes, should be to coil around the set sequence,
Check whether the load to the matching of the generator, such as mismatch, should be replaced.
