Air Cooled Generator Stator Coil Temperature

Introduction The stator coil temperature of air-cooled generator can be analyzed from the following points: 1: Abnormal load and too high voltage will increase iron loss; excessive current will also increase copper loss;

Air Cooled Generator Stator Coil Temperature

It can be analyzed from the following points:

1: Abnormal load and too high voltage will increase iron loss; excessive current will increase copper loss; excessive excitation current will also affect the rotor coil. mount.

2: Insufficient ventilation of the motor, the air duct is blocked.

3: Accumulation of dust in the machine, places with poor working conditions, dust and oil (upper leakage ) In areas where oil and downspout conductive oil) are serious, it is difficult for the motor stator coil to dissipate heat, resulting in an increase in temperature.< /p>

4: Intake air temperature is too high. pupil. You can check whether the charging state of the generator is normal and whether the three-phase current is balanced, whether there is friction noise in the generator and whether the rotor is in contact.

If nothing of the abovee is not true! It is estimated that the motor insulation has aged! Additional insulation must be carried out!

Thermal energy production What is the difference between factory direct air cooling and indirect air cooling?

Possible reasons and solutions for poor air cooler performance:

1. Low cooling water pressure --- increase the water pressure.

2. The cooling water pipe is clogged with foreign objects - clean and clean it.

3. The cooling water temperature is high: this is the most common problem in summer. You may consider using deep well water.

4. The air cooling chamber has a poor seal --- leak.

In addition, you can observe the temperature difference between inlet and outlet water and analyze the cooling effect of the chiller. If the efficiency has reachedAs a standard, this is not a design problem.

I did both. Both direct air cooling and indirect air cooling are based on circulating water cooling. It uses an air cooling island with a large fan and an air cooling island. the heat dissipation surface, you can watch the Suzhou electric field. Indirect air cooling is done through an intermediate cooling tower (similar in shape to a cooling water tower). There are intercooling triangles around the bottom of the intercooling tower. convection inside and outside the intermediate cooling tower. You can take a look at the 660,000 units of the Shaanxi Qinling electric field.
