1. Check the contact of the dynamic and static contact of the electric brake on time, and deal with it immediately if the compression spring is loose or the single touch finger is not parallel to other touch fingers.
2, generator outlet, neutral lead connection part should be secure, unit operation should be regular excitation to static excitation device to the phase of the split-phase cable, static excitation device to rotor slip-ring cable, rotor slip-ring temperature imaging inspection.
3, the new machine into production and old machine maintenance, should pay attention to check the stator core pressure and tooth pressure refers to the pressure deviation, especially at both ends of the tooth, if there is a loose phenomenon, should be dealt with, can be put into operation. The iron loss test should be carried out when the connection or the insulation of iron core is suspected.
4. In the process of manufacturing, transportation, installation and maintenance, attention should be paid to prevent welding slag or metal chips and other small foreign matters falling into the stator core ventilation slot.
5, the generator insulation overheating alarm, should be analyzed the reason, when necessary to stop the elimination of treatment.
