The phenomenon and treatment method of Shangchai generator when the temperature is high?

What happens when the temperature of Shangchai generator is high? How should we deal with these phenomena? Here is a detailed explanation for you:
1. Phenomenon
1. The temperature of the stator coil and iron core of the generator exceeds the allowable value.
2. The temperature of the rotor coil rises abnormally.
3. Negative sequence current is generated, and the three-phase current of the stator may be unbalanced.
4. The vibration of the unit may increase.
2. Processing
1. Check whether the three-phase current of the generator is symmetrical.
2. Compare the meter with the normal situation.
3. Check whether the cooling water temperature, pressure and flow are normal.
4. If there is no abnormality in the above inspections, the reactive load of the generator should be appropriately reduced, and the active load should be reduced when it is invalid.
5. Monitor the temperature of each part of the generator.
6. If the temperature continues to rise due to internal faults, you should ask for a long shutdown for processing.
7. If all inspections are normal, only the temperature patrol instrument indicates that the alarm rises, and the changes of other parameters should be closely monitored, and the thermal workers should be contacted to verify the meter.
The above is the phenomenon and treatment method of Shangchai generator when the temperature is high.
