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) The air temperature at the inlet and outlet of the generator cannot exceed the standard
3) There is no spark in the carbon brush slip ring
4) There is no discharge or spark inside the generator
5) The excitation current and voltage of the generator should be consistent with those of the generator. The primary voltage and current match 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 orThe air 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.
