The reasons for the temperature rise of various parts of the generator are as follows:
1. The three-phase current of the stator is unbalanced;
< /p>
2. The cooling water pressure, flow rate and temperature are abnormal;
3. The generator air path is blocked or the air cooler is cut off, and the water temperature is too high, causing wind Abnormal temperature;
4. Long-term overload.
The handling method when the above reasons occur is:
1. Strictly monitor the three-phase stator current imbalance and shall not exceed the regulations;
2. Adjust the pressure, flow, and temperature of the internal cooling water system;
3. If it is found that air enters the rotor coil, If the cooling water flow decreases and the temperature rises abnormally, the machine should be shut down for processing;
4. Increase the amount of water in the air cooler or pour it into supplementary water.
