Background
14 days 7 months in 2009, a 1.5MW wind generating set in a certain wind farm in Nenggujinhaote city generates fire, and the engine room and the blades are all burnt. The reason for the fire is that in the maintenance process, a maintenance worker electrically welds in the engine compartment and carelessly causes the grease accumulated in the engine compartment to leak so as to cause the fire. 24 days in 2010, a fire accident and a unit collapse accident happen to a certain wind power plant in TongliaoLongshan in inner Mongolia, one 1.5MW unit is damaged, the fire reason is that a brake cannot be braked due to a mechanical or electrical equipment fault, a fan is over-speed and coasts seriously, a large amount of heat is generated by friction, a wheel hub is ignited, and the fire behavior rapidly spreads in strong wind. Then, the overspeed aerodyne generates severe vibration to cause the resonance of the engine room and the tower, and the combustion of the engine room and the tower collapses.
