Yes. There are large and small cycles in the diesel generator cooling system. When the water temperature inside the diesel generator body is lower than 70°C, the water outlet valve of the thermostat is closed and all the cooling water returns to the water. pump through thermostat bypass valve Imported for recycling. A generator is a mechanical device that converts other forms of energy into electrical energy.
What are the dangers if the turbogenerator air temperature is too high or too low?
It has some impact, but I don't think it's big. Reactive power also has an impact on vibrations. In the past we have experienced significant unit vibration, particularly generator bearing vibration. Generally, we tried to reduce the air temperature by increasing the air temperature to a higher rating. The difference in inlet temperature from air temperature also affects the vibration of the unit.
If the generator wind temperature is too high, the temperature of the stator coil and iron core will increase accordingly, causing insulation weakening, loss of mechanical strength , significantly shortening the service life. of the generator, and in severe cases this will result in electricity production. The insulation of the machine is damaged and a breakdown causes accidents.
If the wind temperature is too low, the hydrogen gas will condense and leak, causing water droplets to condense on the generator coil, reducing its insulation capacity and damaging the generator. Therefore, the wind temperature of the generator must be maintained within the range specified by the regulations during normal operation.
