Generator Air gap diaphragms are components installed inside the generator primarily used to improve the cooling effect and enhance the efficiency of the generator. By setting baffles in the air gap of the generator, the baffles guide the cooling airflow more effectively over the critical areas of the rotor and stator, thereby reducing the temperature of the generator components and improving the reliability and lifespan of the generator.

During operation, large generators generate a significant amount of heat, which requires an effective cooling system to maintain their normal operating temperature. The application of air gap baffles can optimize the distribution of the cooling airflow, improve cooling efficiency, and this is especially important in high-power equipment such as large steam turbo-generators and nuclear steam turbo-generators.

Function and Advantages:

1. Enhance Cooling Efficiency: Air gap diaphragms alter the direction and distribution of the airflow, allowing the cooling air to flow more uniformly over the heat-generating components of the generator, thereby improving the overall cooling effect.

2. Reduce Temperature Gradient: By guiding the airflow with the baffles, the internal temperature gradient of the generator can be reduced, avoiding local overheating and improving the thermal stability of the generator.

3. Improve Ventilation System Performance: The application of air gap baffles can increase the axial wind volume of the ventilation channels, enhancing the performance of the ventilation system, and in turn, improving the ventilation cooling effect of the generator.

In practical applications, research on Air gap diaphragms mainly focuses on their design, optimization, and experimental validation. For example, some studies use CFD (Computational Fluid Dynamics) software to simulate and analyze the effect of air gap baffles, to determine the optimal height and position of the baffles. Additionally, there are studies that use experimental simulations to verify the effect of air gap baffles on improving the dynamic air gap eccentricity fault of the generator.

Air gap diaphragms in generators are an effective cooling improvement measure that can significantly enhance the cooling performance and operational reliability of generators. Through in-depth research and optimization of baffle design, the working performance and service life of generators can be further improved. In the design and maintenance of high-power generator sets, the application of air gap baffles is a direction worth paying attention to.
