What is the definition of temperature rise of diesel generator set?

The temperature rise of the diesel generator set is an important indicator in the design and operation of the motor, which indicates the degree of heating of the motor. During operation, if the temperature rise of the motor suddenly increases, it indicates that the motor is faulty, or the air duct is blocked or the load is too heavy .

 

The temperature rise of the diesel generator set is the temperature difference between the motor and the environment, which is caused by the heating of the motor. The iron core of the motor in operation will generate iron loss in the alternating magnetic field, copper loss will occur after the winding is energized, and other stray losses will be generated. These will increase the motor temperature. On the other hand, the motor also dissipates heat. When the heat generation and heat dissipation are equal, the equilibrium state is reached, and the temperature no longer rises and stabilizes at a level. When the heat generation increases or the heat dissipation decreases, the balance will be destroyed, the temperature will continue to rise, and the temperature difference will be expanded, the heat dissipation will be increased, and a new equilibrium will be reached at another higher temperature, but the temperature difference at this time, that is, the temperature rise has increased than before. .

 

Therefore, the temperature rise of the diesel generator set is an important indicator in the design and operation of the motor, which indicates the degree of heating of the motor. During operation, if the temperature rise of the motor suddenly increases, it indicates that the motor is faulty, or the air duct is blocked or loaded. too heavy.
