Brief Introduction Of Generator Hydrogen Cooler
The generator hydrogen cooling air path is shown in Figure 1 and Figure 2. The generator stator and rotor are divided into 11 ventilation zones along the axial direction.
4 FAQs about Generator hydrogen cooling air path
Can a self-circulating hydrogen cooling structure be used for a pm wind generator?
With the continuous improvement of permanent magnet (PM) wind generators' capacity and power density, the design of reasonable and efficient cooling structures has become a focus. This paper proposes a fully enclosed self-circulating hydrogen cooling structure for a originally forced-air-cooled direct-drive PM wind generator.
How does a hydrogen cooling system work?
The proposed hydrogen cooling system uses the rotor panel supports that hold the rotor core as the radial blades, and the hydrogen flow is driven by the rotating plates to flow through the axial and radial vents to realize the efficient cooling of the generator.
How does a hydrogen cooled generator work?
During normal operation, the hydrogen purity is monitored in an 80 to 100% H range to detect air leaks or hydrogen supply problems. During the start-up of a hydrogen-cooled generator, air in the generator is first displaced with carbon dioxide. After the first purge operation is complete, the generator is filled with hydrogen.
How does hydrogen coolant affect a generator?
Generator Eficiency: Maintaining a high concentration of hydrogen coolant increases the cooling eficiency of the generator (see Figure 1 for the cost of decreased hydrogen purity). Plant and Process Safety: Air in the hydrogen coolant can quickly lead to an explosive condition.
