What are the basic methods for inspecting and inspecting power plant generator equipment?

The inspection items of the generator set are as follows:

1) The coil temperature and iron core temperature of the generator cannot exceed the standard

2) Generator inlet and outlet

Air temperature

Cannot exceed the standard

3)

No sparks in the sliding source ring

4) There is no discharge or spark inside the generator< /p>

5) The excitation current and voltage of the generator must be consistent with the primary voltage of the generator, the current matches and cannot exceed the standard.

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 journey generator air; is blocked or theair cooler is turned off and the water temperature Excessively high air temperature causes abnormal air temperature;

4.

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

1. Strictly monitor the imbalance current of the three-phase stator 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 be stopped for treatment;

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