Attention points for local heating of diesel generator set
Xiaobian today to tell you in the hot summer, the emergence of local fever some attention points, and solutions.
1. Check the contact condition of the dynamic and static contacts of the electric brake knife brake on time. If it is found that the pressing spring is loose or the single contact finger is not parallel to other fingers, it needs to be handled immediately.
2. The connection part of generator outlet and neutral point lead shall be reliable. During the operation of the unit, infrared imaging temperature measurement inspection shall be conducted for the phase separation cable from excitation transformer to static excitation device, cable from static excitation device to rotor slip ring, and rotor slip ring.
3. During the commissioning of the new unit and the maintenance of the old machine, attention should be paid to check whether the stator iron core is pressed and whether there is pressure deviation of the tooth pressure finger, especially the teeth at both ends. If the looseness is found, it should be treated before it can be put into operation. The iron loss test shall be conducted when the iron core insulation is suspected or handed over.
4. In the process of manufacturing, transportation, installation and maintenance, attention should be paid to prevent welding slag or metal chips from falling into the ventilation slot of stator core.
5. When the generator insulation overheat alarm, the cause should be analyzed, and if necessary, the generator should be shut down for defect elimination.
