Abstract： To evaluate the fire-extinguishing effectiveness of non-pressurized suspended ultra-fine dry powder extinguishing devices （with 90% of the powder particles ⩽ 15 μ m） in suppressing fires within the nacelle of a wind turbine （including both the nacelle space and the area beneath the nacelle base plate） after undergoing environmental tests such as high temperature， low temperature， vibration， and damp heat， a 50 m 3 fire test chamber was constructed to conduct Class B fire tests. The test also took into account fire scenarios beneath the nacelle base plate and obstructed conditions inside the nacelle. A metal cover plate was placed 20 cm directly above the oil pan to simulate an obstruction， and a metal baffle （20 cm×20 cm in size） was positioned 20 cm below and to the side of the nozzle of the non-pressurized suspended ultra-fine dry powder extinguishing device. After these environmental tests， the startup performance， discharge performance， and fire-extinguishing performance of the devices were tested. The results showed that the non-pressurized suspended ultra-fine dry powder extinguishing devices could start and discharge normally after exposure to high temperature， low temperature， vibration， and damp heat environments， with no adverse impact on their fire-extinguishing performance， and successfully extinguished the fires.
