Reasons for increased temperature of various parts of the generator and how to deal with them

The reasons for the increase in temperature of different parts of the generator are as follows:

1. The three-phase current of the stator is unbalanced;

2. Cooling water pressure, flow and temperature are abnormal

3. The path generator air is blocked or air cooler; is cut off and the water temperature is too high, causing abnormal wind temperature;

4.

The treatment method when the above reasons occur is as follows:

1. Strictly monitor the imbalance of three-phase stator current and must not exceed 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, the cooling water flow decreases and the temperature increases abnormally, the machine should bee stopped for treatment;

4; . Increase the amount of water in the air cooler or pour in additional water.
