What is the reason why the fan blades of the 500 kilowatt generator set are stuck?

Cracked and struck by lightning. According to the official website of China Profile Network, it is displayed.

1. Crack. The fan blades are exposed outdoors and the working environment is harsh. After a long period of operation, certain cracks will occur on the surface, which will affect the stress on the impeller, cause uneven stress on the transmission chain, and cause The gear box gear is faulty, causing the fan blades to get stuck, and the fan blades need to be replaced with new ones in time.

2. When struck by lightning, the blades are made of fiberglass material. There is moisture between the fiber layers during operation. When struck by lightning, a large current passes through the lightning protection channel instantaneously, and the heat generated causes the moisture to instantly Evaporating into water vapor will cause damage to the inner fiber layer of the fan blades, causing the fan blades to get stuck, and the fan blades need to be replaced with new ones in time.
